- Avoid chemical contact with eyes and mucous membranes.
- In case of a large chemical spill, inform the lab technician immediately.
- Shorts or skirts above the knee are not allowed in the laboratory.
- Inform the lab technician immediately in case of danger or accidents.
- If a chemical in a beaker or flask catches fire, cover the flame with a beaker or damp cloth (only if the fire is small).
- Use the appropriate fire extinguisher and fire blanket for larger fires.
- For a large fire, evacuate the lab and alert other buildings.
- Call the Fire Department.
- Gather at the designated assembly point in case of fire.
- Water is effective for fire-related materials like wood, paper, cloth, and plastic but is not effective for electrical fires or flammable liquids.
General Safety Rules for Chemical Reagents

Laboratory Waste
- Do not pour chemical waste into sinks or regular trash bins.
- Chemical waste must be collected in designated containers and delivered to a collection company for neutralization.
- Avoid mixing incompatible chemicals to prevent dangerous reactions.
Toxic Substances
- Treat all chemicals as potential poisons unless otherwise indicated.

Other Safety Issues
- Discuss incomplete lab experiments with the lab technician/instructor.
- When heating a substance in a test tube, point the mouth away from other people.
- Use clamps or tongs to handle hot glassware.
Exam for Lab Safety
