Chemistry Laboratory Safety Handout
Section 1 Personal Safety Practices
A. General guideline
1. Lab coats are recommended when working in chemistry lab. The primary purpose
of a lab coat is to protect against splashes and spills. It should be non-flammable and
should be easily removed in the event of emergency.
2. Safety glasses are to be worn at all time in the lab.
3. Shorts, sandals and open-toed shoes are strictly not allowed. Shoes which fully
cover feet and toes should always be worn in a lab.
4. Do not wear lab coats, gloves or other personal protective clothing out of the lab.
This clothing may have been contaminated and you could spread the contamination.
5. Dangling jewelleries, loose clothing, and long hair are easily caught by fire, trapped
in equipment or contaminated by chemicals. It is recommended not to wear such
jewelleries, clothing and to tie up the long hair.
6. Food and drinks are strictly not allowed in the lab
7. Never work alone in a lab. If you must, make sure someone is aware of your
location and have them call or check on you periodically.
B. Eye Protection
Accidents that can cause serious eye injuries unfortunately occur from time to time in the
course of chemical research experiments. Explosions create flying projectiles and
dangerous chemical sprays; unexpected violent reactions can splash corrosive chemicals
into one's eyes.
1. All personnel, including visitors, must wear eye protection at all times while in
the laboratories. Eye protection is required whether or not one is carrying out
experiments. Visitors should not be permitted to enter a lab unless they wear
appropriate safety glasses
2. Safety glasses with side shields provide the minimum protection acceptable for
regular use. Safety glasses must meet the ANSI (American National Standards
Institute) standard Z87.1-1989 which specifies a minimum lens thickness (3 mm),
certain impact resistance requirements, etc
3. Do not wear contact lenses in the laboratory. Contact lenses offer n
