4. FIRST AID MEASURES
For advice, contact a Poisons Information Centre (Phone eg. Australia 131 126; New Zealand 0 800
764766) or a doctor. Urgent hospital treatment is likely to be needed.

Inhalation: Remove victim from area of exposure - avoid becoming a casualty. Remove
contaminated clothing and loosen remaining clothing. Allow patient to assume
most comfortable position and keep warm. Keep at rest until fully recovered. If
patient finds breathing difficult and develops a bluish discolouration of the skin
(which suggests a lack of oxygen in the blood - cyanosis), ensure airways are
clear of any obstruction and have a qualified person give oxygen through a face
mask. Apply artificial respiration if patient is not breathing. Seek immediate
medical advice.

Skin Contact: If spilt on large areas of skin or hair, immediately drench with running water and
remove clothing. Continue to wash skin and hair with plenty of water (and soap
if material is insoluble) until advised to stop by the Poisons Information Centre or
a doctor.

Eye Contact: Immediately wash in and around the eye area with large amounts of water for at
least 15 minutes. Eyelids to be held apart. Remove clothing if contaminated and
wash skin. Urgently seek medical assistance. Transport to hospital or medical
centre.

Ingestion: Immediately rinse mouth with water. If swallowed, do NOT induce vomiting. Give
a glass of water. Get to a doctor or hospital quickly.

5. FIRE FIGHTING MEASURES

Hazards from Combustible gas. May form flammable vapour mixtures with air. Avoid all
Combustion ignition sources. All potential sources of ignition (open flames, pilot lights,
products furnaces, spark producing switches and electrical equipment etc) must be
eliminated both in and near the work area. Do NOT smoke. Flammable
concentrations of ammonia gas can accumulate in the vapour space of storage
containers/vessels. Caution should be exercised when opening.

Precautions for fire The main products of combustion in air, at or above 780 °C, are nitrogen and
fighters and special water with small amounts of nitrogen dioxide and ammonium nitrate. Ammonia
protective decomposes into flammable hydrogen gas at approximately 450 °C. May form
equipment: flammable mixtures in air. The presence of oil or other combustible material will
increase the fire hazard. Fatalities have occurred as a result of the explosive
nature of the ammonia gas. If involved in a fire, keep containers cool with water
spray. If safe to do so, remove containers from path of fire. Fire-fighters to wear
full body protective clothing and self-contained breathing apparatus. Consider
evacuation.

Suitable Fine water spray, normal foam, dry agent (carbon dioxide, dry chemical
Extinguishing Media: powder). Water spray can be used to bring down the vapour but should not be
sprayed on pools of liquid ammonia.

Hazchem Code: 2RE

6. ACCIDENTAL RELEASE MEASURES
Emergency If contamination of sewers or waterways has occurred advise emergency
procedures: services or State Department of Agriculture.

Methods and Shut off all possible sources of ignition. Avoid breathing in vapours. Work up
materials for wind or increase ventilation. Clear area of all unprotected personnel. Wear
containment and protective equipment to prevent skin and eye contamination and the inhalation
clean up: of vapours. Stop leak if safe to do so.

Additional information: GAS: For a small gas leak, increase ventilation and allow gas to vent to a safe
area. For larger gas leaks, use fire hoses equipped with fog nozzles to disperse
gas down-wind. Do NOT spray water directly on the leak or ammonia container.
LIQUID: Large volumes of gas will evaporate from a liquid spill. For small liquid
spills, increase ventilation and allow the liquid to volatilise to safe area. For
large spills, cover liquid with protein foam 150 mm thick. DO NOT HOSE
LIQUID AMMONIA TO DRAIN; contact with water will accelerate vapourisation
due to liberation of heat upon mixing with water.

7. HANDLING AND STORAGE

Conditions for safe Store ammonia in a cool, well ventilated area, away from sources of heat or
storage: ignition and foodstuffs. Store away from oxidising agents, boron halides, acids,
acid anhydrides, acid chlorides, halogens (eg. chlorine), interhalogens, heavy
metals and their salts, ethylene oxide, hypochlorous acid and acetaldehyde.
Check cylinders regularly for leaks. The transport of liquefied ammonia in a tank
or bulk container made of quenched and tempered steel is prohibited unless the
liquefied ammonia contains not less than 0.2% water mass. May be an
explosion hazard, expecially in confined spaces. Ensure pressure gauges and
fittings are not made of copper, zinc or alloys (eg. brass).

Precautions for safe Avoid skin and eye contact and breathing in vapour. Keep out of reach of
handling: children.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
National Exposure 8 hr TWA = 17 mg/m3 (25 ppm)
Standards 15 min STEL = 24 mg/m3 (35 ppm)

*As published by the National Occupational Health and Safety Commission.

TWA (Time Weighted The time-weighted average airborne concentration over an eight-hour working
Average) day, for a five-day working week over an entire working life.

STEL (Short Term The average airborne concentration over a 15 minute period which should not
Exposure Limit) be exceeded at any time during a normal eight hour work day. According to
current knowledge this concentration should neither impair the health of, nor
cause undue discomfort to, nearly all workers.

These Exposure Standards are guides to be used in the control of occupational health hazards. All
atmospheric contamination should be kept to as low a level as is workable. These exposure standards
should not be used as fine dividing lines between safe and dangerous concentrations of chemicals. They
are not a measure of relative toxicity.

Engineering Ensure ventilation is adequate to maintain air concentrations below Exposure

controls: Standards. Use with local exhaust ventilation or while wearing air supplied
mask. Ammonia gas is generally lighter than air and will disperse under normal
conditions. However, when ammonia liquid contacts air, the gas produced may
be heavier than air. Prevent concentration in hollows or sumps. Do NOT enter
confined spaces where vapour may have collected. An asphyxiant gas which
can lead to the reduction of the oxygen concentration by displacement or
dilution. The minimum oxygen content in air should be 18% by volume under
normal atmospheric pressure.

Personal Protective The selection of PPE is dependent on a detailed risk assessment. The risk
Equipment assessment should consider the work situation, the physical form of the
chemical, the handling methods, and environmental factors.

GENERAL Avoid all contact. Ensure safety shower and eyewash station is close at hand.
Persons who could be subject to ammonia exposure must not wear contact
lenses. Always wash hands before smoking, eating, drinking or using the toilet.
Wash contaminated clothing and other protective equipment before storage or
re-use.

EYE Wear gas tight goggles which have a seal between the face and the frame. A full
face shield shall only be worn to supplement the protection provided by the gas
tight goggles.

SKIN Wear coveralls, or full length trousers with a long sleeved shirt, with gloves and
boots. Available information suggests that gloves made from chlorobutyl-proofed
fabric or butyl rubber should be suitable for intermittent contact. However, due to
variations in glove construction and local conditions, a final assessment should
be made by the user. A complete encapsulating suit is recommended for heavy
exposures.

RESPIRATORY Use with adequate ventilation. Up to 250 ppm - wear vapour respirator with type
K cartridge or air supplied mask meeting the requirements of AS/NZS 1715 and
AS/NZS 1716. Greater than 250 ppm – wear air supplied full face mask meeting
the requirements of AS/NZS 1715 and AS/NZS 1716.

No adverse health effects expected if the product is handled in accordance with this Safety Data Sheet
and the product label. Symptoms or effects that may arise if the product is mishandled and overexposure
occurs are:

Ingestion: Not a likely route of exposure, however, swallowing liquid will result in freeze
burns of the mouth, throat and stomach.

Eye contact: A severe eye irritant. Corrosive to eyes; contact can cause corneal burns.
Contamination of eyes can result in permanent injury. Liquid splashes or spray
may cause freeze burns to the eye.

Skin contact: Liquid splashes or spray may cause freeze burns. Contact with skin will result in
severe irritation. Corrosive to skin - may cause skin burns.

Inhalation: Material is irritant to the mucous membranes of the respiratory tract (airways).
Exposure to concentrations above the Exposure Standard of 25 ppm may cause
irritation to the eyes, nose and throat. Higher concentrations may cause
breathing difficulty, chest pain, bronchospasm, pink frothy sputum and
pulmonary oedema. This may further predispose the patient to the development
of acute bronchitis and pneumonia.

Long Term Effects: Chronic exposure to ammonia may cause chemical pneumonitis and kidney
damage.

Toxicological Data: Inhalation LC50 (rat): 2000 ppm/4hr.

SKIN: Irritant (human).
EYES: Severe irritant (human).
Ammonia: Lowest Published Lethal Concentration (human) = 5,000 ppm/5 min.
Irritation of the respiratory tract and conjunctivae was found in workers inhaling
100 ppm ammonia and 20 ppm caused complaints and discomfort to
unacclimatitised workers. Studies on the effect on man of exposures in the 5-50
ppm range are few, however general field experience in a large number of
workers exposed to ammonia from blueprinting and copying machines indicates
a maximum acceptable concentration without severe complaints of 20-25 ppm.
