- Properly dispose of excess chemicals.
- Leave chemicals in their proper place. Do not carry original containers of chemicals to your benchtop.
- 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.
- Rinse spills off skin immediately. Rinse off any chemicals spilled on the skin immediately with large amounts of water.
- Clean up broken glassware immediately. Place it in the labeled crock at the front of the lab. Obtain replacement glassware from the instructor.
- Properly dispose of waste chemicals. Certain liquids can be poured into the sink and flushed with water while others are poured into designated waste containers. Most solid wastes are placed in designated crocks. Your instructor will provide disposal instructions each lab.
- Notify your instructor immediately of all accidents.
