Chapter 3

The Pesticide Label

This Chapter describes pesticide labeling, which includes the label itself
plus all other information referenced on the label or received from the
manufacturer when you buy the product. By law, pesticide users are
required to comply with all the instructions and use directions found
on the pesticide labeling. The pesticide product label is the main method
of communication between a pesticide manufacturer and pesticide users.
The labeling may include brochures, leaflets, and other information that
accompanies the pesticide product. Pesticide labeling provides applicators
with specific instructions on how to use products safely and correctly.

The labeling is the law, and pesticide applicators are provided with
specific and detailed use information when purchasing the product.

Section 1: The Importance of
Pesticide Labeling
One of the more important tools to ensure the safe and effective use of
pesticides is the product label. Pesticide manufacturers are required by
law to put certain information on the label. Labels are legal documents
providing directions on how to mix, apply, store, and dispose of pesticide
products.

As part of the registration process, the U.S. Environmental Protection

Agency (EPA) must approve all language that the manufacturer (registrant)
proposes to include in the product labeling. The EPA reviews the labeling
to make sure it contains all the information needed for safe and effective
use of the pesticide product. Only after the EPA has reviewed the labeling
and registered the product can a pesticide be sold for use in the United
States. A pesticide must also be registered with the Minnesota Department
of Agriculture (MDA) before it can be sold, distributed, or used in the state.
This Section describes the reasons that pesticide labeling is so important to
the applicator.

Learning Objectives:
1. Explain the difference between the pesticide label and pesticide
labeling.
2. List two reasons why the EPA registration number is placed on a
product label.
3. List at least three reasons why reading a pesticide label is important
to the pesticide applicator.

Basis of Pesticide Labeling
In this manual you will often be advised to “read the label” and “follow the
directions on the label.” That’s because so much important information on
how to use a pesticide is found on the label. This information is the result
of years of research and testing for each pesticide that is put on the market.
A manufacturer may make and screen thousands of compounds before
finding one that can pass all the tests needed for a label to receive clearance
from the EPA. These tests include the following:
w Toxicological tests to determine possible health hazards to humans
and animals.
w Metabolism studies to see how long it takes a compound to break
down into simple, less toxic materials.
w Residue tests to find out how much of the pesticide or its
breakdown products remain on farm products, such as crops, meat,
milk, and eggs.
w Soil movement tests to determine how long a pesticide stays in the
soil, and how it moves in the soil and groundwater.
w Wildlife tests to determine the immediate and long-range effects
on wildlife.
w Performance tests to prove that the pesticide controls the pest and
improves the quality and quantity of the crop.

The EPA reviews these test results and determines whether to approve the
pesticide. Once it is approved, the pesticide is registered. Information on
the label and labeling must not differ from the information given to the
EPA when the product was registered.

The label is the information printed on or attached to the pesticide

container or wrapper; labeling refers to the label plus all additional product
information, such as brochures and flyers, provided by the manufacturer
or dealer. Both the label and labeling are legally binding documents and
must be followed. State labels—that is, special local needs and emergency
exemption labels—should be in your hands at the time of application.

Types of Pesticide Registration

You are responsible for applying only pesticides registered with both the
EPA and the MDA. A registered pesticide is one that has been researched
and approved by the EPA for uses that are specified on the label and
labeling. Look for the EPA registration number that must appear on all
pesticide labels that confirms EPA registration.

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) allows

for three variations from the standard pesticide registration process, each of
which is named for the part FIFRA where they are described.

1. The
Chapter 3. Integrated Pest
Pesticide Management
Label
65
 24(c) Special Local Need Registrations
Special Local Need (SLN) registrations, also called 24(c) registrations, allow
states to apply to EPA to expand or limit labeled uses of already registered
pesticides to accommodate area-specific conditions. In some cases, SLN
registration may allow pesticide use on minor crops not specified on the label, and
in other cases SLN registration will add more restrictive use limitations than those
found on the label. You must have the SLN additional labeling in your possession
to use the pesticide for any purpose not listed on the label. These registrations are
legal only in the region, state, or local area specified in the SLN labeling.

Section 18 Emergency Exemptions

Emergency exemptions address pest problems for which no pesticides are
registered. The EPA can issue an emergency exemption at the request of the
state regulatory agency. Usually these needs are based on specific public health
emergencies or other crises that require the use of an unregistered pesticide.
There must be no feasible alternative to the exemption. Known as a Section 18
exemption, it allows the sale and use of a certain pesticide product for a specific
non-registered purpose during a specified period of time. For example, in 2004
some products received Minnesota Section 18 Emergency Exemption for use on
soybeans to combat soybean rust. Applicators must have a copy in their possession
and follow the instructions in the Section 18 approval letter from EPA to the state
to legally use the product.

laws and
regulations. When to Read the Pesticide Label
It is important for applicators to read and understand the pesticide label. Important
times to read the label include:
w Before buying the pesticide. Make sure the pesticide is registered for your
intended use. Understand any site restrictions. Be certain its use is suitable
for weather conditions at the time of application. Find out what personal
protective equipment and special application equipment will be needed.
w Before mixing and applying the pesticide. Learn how to mix and apply
the material safely. Find out what precautions to take to prevent exposure
to people and non-target organisms. Learn what first aid and medical
treatments are necessary should an accident occur.
w When storing pesticides. Find out how to store the pesticide properly.
Understand the special precautions to prevent fire hazards or spills.

Section 2: Parts of the Label
It is the user’s responsibility to read and understand the label before buying,
using, storing, or disposing of a pesticide. This Section will describe the
various label components and what important information these label parts
provide for pesticide applicators. Parts of the example label on page 64 will
be used to illustrate label parts.

Learning Objectives:
1. Compare and contrast pesticide trade, common, and chemical
names.
2. List and define pesticide label “signal words.”
3. Describe where you should look on a pesticide label to find out what
to do if a pesticide gets on the skin, in the eyes, is swallowed, or
inhaled.

Trade, Brand, or Product Name

The brand or trade name shows up plainly on the front panel of the
label and is the one used in advertisements and by company sales people.
Manufacturers use different trade names, even though the products contain
the same active ingredient. The brand name often indicates the type of
formulation and the percentage of active ingredient present. For example,
in the sample label on page 68, “VIP No Pest Gel” is a registered trade or
brand name of the product. Gel in the brand name indicates the product’s
formulation.

Label
67
 Ingredient Statement
Every pesticide label has an ingredient statement that provides the amount
of active ingredients (those that the manufacturer claims have effects
on the targeted pests) in the formulation, the official chemical name, and
amount of other ingredients.

Other ingredients (often called inert ingredients) are substances added

to the active ingredients to formulate the final usable product, but have no
effect on targeted pests. Unlike active ingredients, these other ingredients
are considered proprietary information. Inert ingredients that are not
considered hazardous and are less than 1 percent of the product may not
require listing on the MSDS label (see Section 3 in this Chapter for more
information about the MSDS). The other ingredients may have effects on
humans or other animals, plants, or the environment. However, the EPA
maintains a list of other ingredients that are not considered to pose excess
hazards to non-target organisms, and manufacturers choose from this list
when they formulate products.

The chemical name is the scientific name that identifies the chemical
components and structure of the pesticide’s active ingredient. Because
chemical names of active ingredients are usually complex, many are given
a shorter common name. Only those common names officially accepted
by the EPA may be used in the ingredient statement on the pesticide label.
Labels are not required to include the common name in the ingredients
statement. By referring to the common or chemical names, rather than the
brand name alone, you are certain of getting the right product for your
needs. In the sample label on page 69, “galactothion” is the common name
and “0,0-diethyl methyl phosphorothiate” is the chemical name of the
active ingredient.

Use Classification Statement

The EPA classifies some pesticide products as restricted use (RUP). Every
product that is federally classified as a restricted-use pesticide must include
the following statement at the top of the front panel of the pesticide label:

Unclassified or general-use pesticides can be purchased and used by

the general public or by farmers without certification. Farmers and
other producers of agricultural commodities must be certified as private
applicators to apply RUPs in Minnesota. Remember if you hire a service
to apply pesticides on your farm, the applicator must hold a commercial
pesticide applicator license to apply any pesticide, RUPs and non-RUPs.

Type of Pesticide
The type of pesticide is usually listed on the front panel of the pesticide
label. This short statement indicates in general terms where the product can
be used. Examples of description of pesticide types include the following:

Insecticide for control of certain insects on fruits, nuts, and ornamentals.

Insecticide for broad-spectrum control of crawling, flying, and wood-infesting

insect pests on indoor and outdoor surfaces, as well as pests of trees,
landscape ornamentals, and residential and commercial lawns.

Herbicide for the control of woody brush and weeds.

 Net Contents
The pesticide label must show how much product is in the container. This
is expressed as pounds or ounces for dry formulations or as gallons, quarts,
or pints for liquids. Liquid formulations may also list the pounds of active
ingredient per gallon of product.

Registration number Establishment

number

Name and Address of Manufacturer

The law requires that the manufacturer or formulator of a product put the
name and address of the company on the label.

Emergency Telephone Number

Many pesticide manufacturers include emergency telephone numbers on
their product labels to provide customers technical information on how to
respond in the event of an emergency (poisoning, spill, fire) involving their
products.

Registration Numbers
An EPA registration number must appear on all pesticide labels, except
those designated by EPA as 25(b) minimum-risk pesticides. The EPA
registration number indicates that the pesticide product has been registered
and its label approved by the EPA. For special local needs registration, the
EPA registration number will start with SLN.

Establishment Number
Don’t confuse the EPA establishment number with the EPA registration
number. An EPA establishment number identifies the facility where the
pesticide was produced. This is required on the product label in case a
problem arises or the product is found to be adulterated in any way.

Signal Words and Symbols

Most pesticide labels must include a signal
word. This important designation gives
the user an indication of the relative acute
human toxicity and help you choose the
least toxic chemical that provides the
PRIVATE PESTICIDE APPLICATOR TRAINING MANUAL 19th Edition
70
needed level of pest control (for more about signal words, their meaning
and toxicity, see chart on page 234, Appendix A, Pesticide Toxicities and
Chapter 6, Health and Safety). The signal word must appear in large letters
on the front panel of the pesticide label along with the statement “Keep
out of Reach of Children.” Very low toxicity pesticides (Toxicity Category
IV) are no longer required to display a signal word, although many
manufacturers still include a “CAUTION” signal word on the label of these
products.

Precautionary Statements
Pesticide labels contain statements on how applicators can protect
themselves, their employees, and other persons or animals. Sometimes
these statements are listed under the heading “Hazards to Humans and
Domestic Animals” or may be included in other sections of the label.
Personal protective equipment (PPE) listed in precautionary statements
included on the label must be worn during use of the pesticide.

Hazard statements (hazards to humans and domestic animals,

environmental hazards, and physical or chemical hazards) are not located
in the same place on all pesticide labels. Some labels group them under the
headings listed above. Other labels list them on the front panel beneath the
signal word. Still other labels list the hazards in paragraph form somewhere
else on the label under headings such as “Note” or “Important.” Before
using a pesticide, read and understand the label to ensure that you handle
the product properly and safely. The following types of precautionary
statements found on the label give the pesticide applicator the best
instructions on how to prevent problems.

Routes of Entry and Specific Action Statements

Routes of entry and specific action statements go hand-in-hand. Routes of
entry indicate how the pesticide enters the human body (orally, inhaling,
or absorbing through the skin and eyes). Specific action statements usually
follow, either directing or recommending specific precautions. These
statements are particularly important if the label does not list required
personal protective equipment.

These statements are directly related to the pesticide’s acute toxicity and
signal words. Many pesticide products are hazardous by more than one
route of entry. Study these statements to understand how you may be
exposed and what to do to prevent exposure. The table on page 73 shows
examples of signal words and corresponding precautionary statements that
you might see on a label.

Protective Clothing and Equipment Statements

Pesticide labels vary in the type of information they contain on protective
clothing and equipment. Some pesticide labels fully describe appropriate
protective clothing and equipment, while others carry no PPE information

 at all. Some labels list the kinds of respirators that must be worn when
handling and applying the product; others require the use of a respirator,
but do not specify a type or model.

More detailed information may be found on the pesticide’s Material Safety

Data Sheets or MSDS (see Section 3 for more on MSDS). Follow all
directives on protective clothing or equipment that appears on the label and
in the MSDS. Labels list the minimum PPE required, but applicators can
choose to use more. To determine the proper type of protective clothing
and equipment, also consider the signal word, the route of entry statements,
the specific action statements, and the MSDS.

Other Precautionary Statements

Labels often list other precautions that should always be followed when
handling the product. These are self-explanatory and common sense
statements. The absence of such statements from the label does not indicate
that these precautions should be ignored.

w Do not contaminate food or feed.

w Remove and wash contaminated clothing before reuse.

 First Aid
The first aid section on the label, sometimes called “Statement of Practical
Treatment,” lists actions to be taken in case of poisoning or accidental
exposure. All DANGER labels and some WARNING and CAUTION
labels contain a note to physicians describing the appropriate medical
procedures and antidotes for poisoning emergencies. The label should
always be available in case of emergencies.

Statement of Practical Treatment

w If in eyes: Flush with plenty of water. Get medical attention if
irritation persists.
w If on skin: Wash with plenty of soap and water. Get medical
attention if irritation persists.
w If swallowed: Do not induce vomiting. Promptly drink a large
quantity of milk, egg whites, or gelatin solution. If these are not
available, drink large quantities of water. Never give anything
by mouth to an unconscious person. Call a physician or Poison
Control Center immediately.
w If inhaled: Move victim to fresh air.

Environmental Hazards
Some products are classified as restricted-use because of the environ-
mental hazards they may pose. Watch for special warning statements
on the label concerning hazards to the environment. Different types of
environmental hazard statements may be included on the label.

General Environmental Statements

General environmental label statements are reminders to follow certain
common-sense procedures to avoid contaminating the environment. The
absence of any or all of these statements does not mean that you do not
need to take adequate precaution. Examples of general environmental
statements include:
w Do not apply when runoff is likely to occur.
w Do not apply when weather conditions favor drift from treated
areas.
w Do not contaminate water by improperly disposing of rinse water
and other pesticide wastes.
w Do not apply when bees are likely to be in the area.
w Do not apply directly to water or to areas where surface water is
present or to intertidal areas below the mean high-water mark.
w The use of this chemical in areas where soils are permeable,
particularly where the water table is shallow, may result in
groundwater contamination.

PRIVATE PESTICIDE APPLICATOR TRAINING MANUAL 19th Edition

74
 Example of an Environmental Hazards Label
Statement
This product is toxic to aquatic invertebrates. Drift and runoff may
be hazardous to aquatic organisms in neighboring areas. Under some
conditions, this chemical may also have a high potential for runoff
into surface water for several weeks or months after application. Do
not cultivate within 10 feet of aquatic areas so as to allow growth
of a vegetative filter strip. Drift from applications of this pesticide is
likely to result in damage to sensitive aquatic invertebrates in water
bodies adjacent to treatment area.

For terrestrial uses, do not apply directly to water or to areas where

surface water is present or to intertidal areas below the mean high-
water mark, except under forest canopy when aerially applied to
control forest pests. Do not contaminate water when disposing of
equipment, wash waters, and rinsate. Do not apply when weather
conditions favor drift or runoff from areas treated.

This pesticide demonstrates the properties and characteristics

associated with chemicals detected in groundwater. The use of this
chemical in areas where soils are permeable, particularly where the
water table is shallow, may result in groundwater contamination.

Hazards to Wildlife Statements

If a pesticide is especially hazardous to wildlife, the label will say that. The
label statement helps applicators choose the safest product for a particular
job and reminds them to take extra precautions. For example:
w This product is highly toxic to bees.
w This product is extremely toxic to fish and aquatic invertebrates.
w This product is toxic to birds and other wildlife.

Physical or Chemical Hazards

This section of the label describes any special fire, explosion, or chemical
hazards the product may pose. For example:
w Flammable—do not use, pour, spill, or store near heat or open flame.
Do not cut or weld container.
w Corrosive—store only in a corrosion-resistant tank.

Agricultural Use Requirements

An “Agricultural Use Requirement” box is found only on labels of products
that are covered by the EPA Worker Protection Standard (WPS – see Chapter

(REI) and PPE for WPS-covered handlers and early-entry workers. The
WPS REI specifies how much time must pass between the application of a
pesticide and the reentry of unprotected workers into a treated area.

If there are multiple REIs on a label, you can usually find the appropriate
REI at the beginning of the use-direction section for each crop. If no REI
statement or other entry restrictions appears on the label, then all persons
should wait at least until sprays have dried or dusts have settled before
reentering a treated area without label-required PPE. An example of an
Agricultural Use Requirements is shown below.

Example of Agricultural Use Requirements

Use this product only in accordance with its labeling and with the
Worker Protection Standard, 40 CFR, part 170. This standard contains
requirements for the protection of agricultural workers on farms,
forests, nurseries, and greenhouses, and handlers of agricultural
pesticides. It contains requirements for training, decontamination,
notification, and emergency assistance. It also contains specific
instructions and exceptions pertaining to the statements on this label
about personal protective equipment (PPE) and restricted-entry
interval. The requirements in this box only apply to uses of this product
that are covered by the Worker Protection Standard.
Do not enter or allow worker entry into treated areas during the
restricted-entry interval (REI) of 12 hours. Exception: if the product
is applied by drenching, the Worker Protection Standard, under certain
circumstances, allows workers to enter the treated area if there will be
no contact with anything that has been treated.
PPE required for early entry to treated areas that is permitted under the
Worker Protection Standard and that involves contact with anything
that has been treated, such as plants, soil, or water is:
w Coveralls.
w Waterproof gloves.
w Shoes plus socks.

Non-agricultural Use Requirements

The requirements in this Section apply to pesticide uses that are not within
the scope of the WPS, such as the application of pesticides to lawns, golf
courses, ornamental plantings, structures (except greenhouses), aquatic
areas, and rights-of-way. Specific reentry times are not generally listed
for these uses, though the label often cautions people and pets not to enter
treated areas until spray has dried or dust has settled.

 Example of Non-agricultural Use Requirements
The requirements in this box apply to uses of this product that are NOT
within the scope of the Worker Protection Standard for agricultural
pesticides (40 CFR, part 170). The WPS applies when this product
is used to produce agricultural plants on farms, forests, nurseries, or
greenhouses. Do not allow others to enter treated areas until sprays
have dried.

Storage and Disposal

All pesticide labels contain general instructions for the appropriate storage
and disposal of the pesticide and its container. One or more statements
may appear in a special section of the label titled “Storage and Disposal”
or under headings such as “Important,” “Note,” or “General Instructions.”
These may include:
w Store herbicides away from fertilizers, insecticides, fungicides, and
seeds.
w Store at temperatures above 32°F (0°C).
w Do not reuse container; render unusable.
w Do not contaminate water, food, or feed by storage or disposal.
w Triple-rinse, or equivalent, and dispose of in an approved landfill.

More information about storage and disposal of pesticides in Minnesota

can be found in Chapter 7, Safe Handling.

Directions for Use

These instructions provide the directions on how to use the product. The
use instructions will tell you:
w The crop, animal, or site the product is intended to protect.
w The pests that the manufacturer claims the product will control.
w How much to use (rate) and how often.
w Where and when the material should be applied.
w The proper mixing instructions.

 Label Summary
Many terms are used on labels to describe when and how to use pesticides.
Your understanding of these terms will help you obtain optimum results
from pesticide applications. Refer to the Appendix B, Glossary in this
manual to look up a term. If you do not understand the directions on a
label, check with your pesticide dealer or salesperson, the University of
Minnesota Extension, or the Minnesota Department of Agriculture.

The label provides a wealth of information for pesticide applicators.

Remember, the label is a legal document. It is illegal and considered a
misuse to use any registered pesticide in a manner inconsistent with its
labeling. Following label directions maximizes effective control of pests
and minimizes hazards to people and the environment.

Section 3: Material Safety Data

Sheets (MSDS)
Material Safety Data Sheets (MSDS) are very useful documents for
learning about specific chemical and physical properties of pesticides or
other potentially hazardous substances. Manufacturers of these substances
are required to develop and to provide upon request an MSDS for each
product. The information in the MSDS complements the pesticide label.
This Section describes the information a pesticide applicator can obtain
from the MSDS and where to find them.

Learning Objectives:
1. List three uses of MSDS.

While the pesticide label focuses on how to use the product safely, the
MSDS provides technical information about the product’s hazards to
workers and end users. The MSDS provides detailed information about
the product’s composition, physical and chemical properties and hazards,
toxicological and ecological information, and first aid procedures.

Emergency responders often require the product MSDS before responding

to incidents involving pesticides and other chemicals. Businesses using
pesticides and other products are required to keep appropriate MSDS and
make them available to workers or others who may come into contact with
the substance, its diluted end product, or its residues. Private applicators
should obtain MSDS for the pesticides they use. MSDS are available from
manufacturers and distributors of pesticides.

Pesticide applicators should review the toxicological, first aid, and PPE
sections of the MSDS before handling a pesticide concentrate. Because
MSDS are technical documents, parts of them can be difficult to under-
stand. Ideally, the MSDS is used in combination with the pesticide label,
but it should never be used in place of the actual product label.

Components of the MSDS

The information contained in the MSDS may appear under various
headings and does not have to follow the same order, but the elements of all
MSDS are the same.

Chemical Product Identification

As with the pesticide label, the MSDS identifies the ingredients in
the product by common (generic) name, percentage of the active
ingredient(s), and percentage of inert or other ingredients. This section
of the MSDS may also provide information about the class of chemical,
such as “organophosphate insecticide” or “chlorophenoxy herbicide.”
Because chemicals in a particular class share certain characteristics, this
information may be helpful, particularly to the health-care professional.
This section also may provide brand names of other products with the same
composition.

 Physical and Chemical Properties
This Section describes the product’s physical appearance and provides
information about how the product behaves under certain physical and
chemical conditions. Particularly relevant are the measures for water
solubility, vapor pressure, soil KOC, stability, and freezing/boiling
point. These physical and chemical properties can impact mixing and
storage, drift, leaching, and runoff. More information about water solubility
and vapor pressure can be found in Chapter 5, Protecting the Environment.

The Soil Organic Carbon-Water Partitioning Coefficient (or soil KOC)

is the ratio of the mass of a chemical that is adsorbed by soil per unit mass
of organic carbon in the soil per the equilibrium chemical concentration
in solution. Soil KOC values are useful in predicting the mobility of
pesticides; higher KOC values correlate to less mobility, while lower KOC
values correlate to more mobility. This parameter is used to calculate a soil
concentration that protects groundwater.

From a human exposure standpoint, products with high water solubility are
not stored in body fat but excreted in urine. Products with relatively high
volatility are more likely to be detected through smell than products with
low volatility. Some MSDS provide direct information about the odor of
a product. Products may range from practically odorless to very strong in
odor.

Stability and the freezing and boiling points of a substance determine

whether a product can be stored over the summer or winter. Freezing and
excessive heating may degrade the product, resulting in a loss of efficacy
against the pest.

Fire and Explosion Hazards
Some substances can spontaneously catch on fire at a certain temperature.
In such cases, the MSDS identifies the temperature, called the flash point,
at which the substance catches fire. The MSDS may list conditions to avoid,
such as materials that are incompatible with the product. For instance, some
substances can react with galvanized containers to form hydrogen gas, a
highly combustible material.

Toxicological Information/Human Health Data

The MSDS identifies by what route(s) of exposure the product may be
harmful (for example, ingestion, through the mouth; dermal, through
the skin or eyes; and inhalation, by breathing in the product’s vapors).
The MSDS also summarizes results of toxicological tests performed on
laboratory animals and discusses the potential for effects on humans. Here
is a list of toxicological and health data commonly found on MSDS:
w Acute toxicity,
w Chronic toxicity,
w Delayed toxicity,
w Oncogenicity (ability to cause tumors),
w Carcinogenicity (ability to cause malignant tumors, or cancer),
w Teratogenicity (ability to cause birth defects), and
w Fetotoxicity (other adverse effects on the fetus, such as low birth
weight or spontaneous abortion).

The MSDS also lists symptoms of acute overexposure and usually lists
medical conditions that may be aggravated by exposure to the product.
It is important to remember that a substance’s level of acute toxicity is not
related to its ability to cause chronic or delayed effects. The MSDS usually
provides specific information about the product’s ability to cause eye and
skin irritation or allergic responses.

Allergic responses are also not related to the chemical’s level of acute
toxicity. Thus, it is possible for a slightly toxic pesticide (Category III)
to be associated with adverse long-term effects or allergic reactions and,
conversely, for a highly toxic pesticide (Category I) to have no known long-
term or allergic effects. (See Chapter 6, Health and Safety, for a discussion
of toxicity categories.)

Cholinesterase Inhibitors
If the pesticide can inhibit cholinesterase, an enzyme that regulates
nerve impulses, the MSDS may identify the pesticide as a cholinesterase
inhibitor. Cholinesterase inhibitors are a class of compound that includes
chemical warfare nerve agents and certain insecticides. Cholinesterase
inhibitors can have serious health effects, such as depression of respiratory
drive, paralysis of muscles of respiration, and airway constriction.

 Regulatory Exposure Limits
Some compounds have regulatory limits on the concentration and the
amount of time a worker can be exposed to them. These limits are based
on the concentrated product, rather than the diluted or mixed form, and are
listed in the MSDS.

Personal Protection Recommendations

Many products do not require special protective equipment. Others require
chemical-proof gloves, goggles, respirators, or other gear. Remember that
the equipment listed on the MSDS pertains to the product as formulated.
Refer to the pesticide label to check whether protective gear listed on the
MSDS is required to be worn while handling the diluted product.

Additional Information
The MSDS must also provide:
w Emergency and first aid procedures—specific information
about first aid and emergency treatment for persons exposed to the
product. The MSDS provides treatment information for emergency
responders and physicians.
w Ecological or environmental hazards—information on acute
and chronic effects on wildlife in similar terms as the statements
pertaining to humans.
w Spills, fires, and accident procedures—directions for cleaning up
spills and leaks, as well as special information for firefighters.
w Storage and disposal—directions on how to store and properly
dispose of the pesticide. This information may range from very
specific to quite general.

Have an MSDS available for every pesticide product that you are using.
Read both the pesticide label and the MSDS for a more complete picture of
the potential hazards associated with the pesticide. Both the label and the
MSDS provide valuable information in case of a pesticide emergency.

Summary
The language on pesticide labels is strictly regulated by the EPA, in
coordination with pesticide manufacturers, to provide precise information
on how to use pesticides correctly and safely. It is the applicator’s
responsibility to read, understand, and follow the label directions to ensure
that pesticides are applied according to regulations. The label directions
are written to instruct the applicator how to use the pesticide for effective
control of the target pest while minimizing harmful effects to other
organisms and the environment. Make sure the pesticide has both federal
and state registration for its intended use.

Pesticide labels in combination with MSDS provide a wealth of information
on the hazards associated with each pesticide. Carefully review these
documents before applying any pesticide. Applicators are better prepared to
avoid any harmful effects if they understand the properties of the pesticide
thoroughly. Remember, it is the applicator’s responsibility to ensure that
pesticides are applied effectively and as safely as possible.
