The following safety rules must be followed at all times in the
laboratory. The chemical laboratory is not necessarily a dangerous place.
Intelligent precautions and a proper understanding of techniques to be
followed make the chemistry laboratory no more dangerous than any other
classroom.
1. Safety goggles (department approved) must be worn in the lab at
all times. Glasses and contact lenses are not acceptable eye protection.
Students who do not follow this rule will be asked to leave the lab
immediately.
2. Never eat or drink in the lab. Food may pick up toxic chemicals.
3. Never inhale fumes or vapors. Use fume hoods for dangerous or
irritating chemicals. Always waft odors toward your nose with your hand.
4. Never taste any chemical. Some chemicals are very corrosive and
poisonous in very small quantities.
5. Never perform an unauthorized experiment and never work in
the lab without an instructor in charge. An accident may happen
when mixing simple chemicals.
6. Never remove anything (chemicals, glassware, etc.) from the lab.
It is illegal!
7. Label all containers to identify their contents.
8. Never put anything back into a reagent bottle. Once a reagent has
passed the mouth of its container, it has passed the point of no return.
Always take as little of a chemical as possible. Use only clean, dry
spatulas for removing chemicals from bottles. Properly dispose of excess
chemicals.
9. Leave chemicals in their proper place. Do not carry original
containers of chemicals to your benchtop.
10. Avoid touching hot objects. Burns are a common accident in the
chemistry lab. Be careful when using hot plates and objects which have
been heated on them. Use beaker tongs to remove hot containers from the
hot plate.

1. Laboratory safety The purpose of this ppt is to inform you about the rules and regulations of working safely in a laboratory.

2. Introduction Laboratory safety rules are a major aspect of every microbiology lab. Each student in microbiology laboratory must follow specific safety rules and procedures.

3. Why is Lab Safety Important? Lab safety rules and symbols are needed so that students do not injure themselves or their classmates.
