Study Notes
Laboratory Safety Rules
- Follow teacher instructions strictly
- Keep exits and pathways clear
- Maintain a clean and tidy laboratory
- Wear safety goggles when heating or mixing substances
- Tie up long hair and secure school ties during experiments to prevent fire hazards
- Thoroughly wash hands after experiments
- Report all accidents to the teacher immediately
General Safety Rules - Do's and Don'ts
- Do: Follow teacher instructions; keep the lab clean; wear safety goggles; tie back hair; wash hands; report accidents
- Don't: Enter the lab or conduct experiments without permission; eat, drink, run, or play in the lab; leave experimental setups unattended; point test tubes at others; touch hot objects; touch electric plugs with wet hands; smell or taste chemicals without instructions
Handling Common Laboratory Accidents
- Cuts: Clean and dress the cut, wash the affected area under running water
- Heat burns: Wash the affected area under running water
- Splashes of chemicals on skin: Wash the affected area under running water
- Splashes of chemicals in eyes: Flush the eyes with distilled water from an eye wash bottle
Fire in the Lab
- Keep calm and report the fire to the teacher immediately
- Necessary conditions for a fire to occur: fuel, high temperature and oxygen
- The fire triangle represents these conditions
- Methods to put out a fire include turning off gas stove, covering the flame, spraying water
- Fire extinguishers, sand buckets, and fire blankets are used to extinguish fires.
Oxygen
- Covering a burning candle with an inverted jar removes oxygen, extinguishing the flame
- Charcoal fires can be made to burn more brightly by removing ashes and exposing the charcoal to more oxygen.

- Turn off the gas stove
- Cover the flame with a metal lid
