LABORATORY SAFETY RULES, PROCEDURES AND REGULATIONS
Safety Rules
Ensuring laboratory safety is not just the responsibility of the teacher; it is the responsibility of
everyone working in the laboratory. You are expected to be familiar with the safety rules and to conduct
your laboratory work in a safe manner at all times. The science teacher will review the following safety rules
and regulations with you and will point out the location and operation of the safety equipment (e.g.,
emergency eyewash station) and other available safety equipment. You must follow the minimum health and
safety protocols in compliance with the IATF (Inter-Agency Task Force) standards.
Personal Protective Equipment and Proper Attire
1. You must wear a face mask all the time.
2. You must wear approved safety goggles. It must always be worn while a hazardous experiment is in
progress. The goggles must have indirect ventilation which conforms with ANSI Z87.1-2015 and
with D3 marking. Contact lens are strongly discouraged.
3. Lab coat and surgical gloves are highly recommended. They offer additional protection against
chemical splash or spill. They are either available from the bookstore or online stores.
4. Wear full-length pants or full-length skirt.
5. Wear a shirt that completely covers your torso. Exposed shoulders, backs, abdomens, and hips are
not safe in the lab.
6. Wear close-toed shoes with back (e.g., sneakers). No open-toed shoes, flip-flops, or sandals.
7. Long hair must be pulled back and properly restrained, and jewelry should be worn sparingly.
Safety Precautions
1. If you have fever, cough, nasal problems, any symptoms of Covid-19, and any Medical conditions
that might be exacerbated by working closely with chemicals, please consult with the School Nurse
for further diagnosis.
2. Before entering the laboratory, make sure to sanitize with alcohol, hand sanitizer, or washing your
hands with soap and water; and step on the foot bath. Monitor your body temperature.
3. Always maintain social distancing at least 6 feet apart.
4. Always sanitize the table and chairs with warm water before placing notebooks and sitting down.
5. Cellphone use is not allowed in the lab. Please turn the cell phone to vibration, silent, or off. If you
receive a call or need to make a call, please ask your teacher’s permission to answer the call outside.
6. Do not eat and drink inside the lab.
7. Sweep up broken glassware immediately and dispose it in the designated disposal area.

8. Familiarize yourself with the experimental procedure before beginning work; take notes of any
procedure that might pose a safety problem. Your Science teacher should point out all safety hazards
before the beginning of each experiment.
9. No unauthorized experiments may be performed.
10. In case of an accident, inform your Science teacher immediately.
11. Treat all chemicals as if they were potentially dangerous. If a chemical comes into contact with your
skin or eyes, wash immediately with plentiful amounts of tap water. Inform your Science teacher if
any exposure to chemicals takes place.
12. Avoid distracting or startling other students. Practical jokes or horseplay will not be tolerated at any
time.
13. Sanitize yourself and the area of work before leaving the laboratory.
Conduct of Experiments
1. When heating or carrying out reactions in a test tube, never point the mouth of the tube at your
neighbor or yourself.
2. Never taste a chemical; never smell a chemical unless instructed to do so. If instructed to smell a
chemical, fan vapors toward your nose and inhale cautiously.
3. Never pour water into acid; slowly add the acid to the water with constant stirring in a beaker or
flask, not in a graduated cylinder. Pouring water into acid may result in a violent reaction!
4. Never place hot glassware directly onto the table.
5. Never pipet liquids by mouth; use a mechanical or safety pipet bulb.
6. Each student is responsible for cleaning up all spilled chemicals at his/her working area. Consult the
Science teacher if uncertain about the method of cleanup.
7. Always return securely capped reagent bottles in the lab to their proper place immediately after use.
Never return unused chemicals to a reagent bottle to avoid contamination of the entire bottle.
8. Always consult your Science teacher for the proper disposal of chemicals. Make sure you dispose of
each chemical in the proper bottle. Placing a chemical in the wrong bottle may result in undesirable
chemical reactions (i.e. fire).
9. Use equipment only for its designed purpose. Consult with your Science Teacher for proper handling
procedure.
10. Wash your glassware at the end of the lab with hot and soapy water so that it will be ready for use at
the next period.
