Study Notes
Laboratory Safety Hazards
- Exposure to blood, body fluids, and specimens can contain pathogenic bacteria and viruses.
- Acids, alkalis, and toxic chemicals pose a risk.
- Ineffective radioactive waste disposal can lead to contamination.
- Fire and electrical accidents are potential hazards.
General Safety Rules
- Read instructions thoroughly before starting an experiment.
- Wear safety goggles to protect eyes from chemicals, heated materials, or projectiles.
- Wear a lab coat, gloves, face mask, and hair cap for protection.
- Wash hands with soap and water after handling chemicals.
- Avoid touching your face during lab work.
- Do not mix chemicals unless instructed to do so.
- Report spills or accidents immediately to a teacher.
- Clean up your lab area after completing an experiment.
Glassware Safety
- Dispose of broken glassware in a designated glass disposal container.
- Ensure glassware is placed on a stable surface at a safe distance from the edge when pouring liquids.
- Inform the teacher if glassware breaks.
Heating Safety
- Use protective gloves when handling hot objects.
- Never reach across an open flame.
- Point the open end of a test tube being heated away from people.
- Heat test tubes slowly and evenly by moving them around the flame.
- Only heat thoroughly dry glassware.
- Use a wire gauze platform on a ring stand to heat glassware, not by hand.
First Aid
- Burns: Immediately flush with cold water.
- Cuts and Bruises: Do not touch open wounds without safety gloves. Apply pressure to minor cuts to stop bleeding. Apply a cold compress to bruises to reduce swelling.
- Eyes: Immediately flush with plenty of water for several minutes.
