Final answer:
In case of emergencies in the laboratory, specific safety equipment should be used. For a large fire on the bench top, use a fire extinguisher.
Step-by-step explanation:
1. Large fire on the bench top: In case of a large fire on the bench top, you should use a fire extinguisher. Know the location of the fire extinguisher in the laboratory.
2. Fire on a person: If there is a fire on a person, the person should stop, drop, and roll to extinguish the flames. Alternatively, they can use a fire blanket to smother the flames.
3. Chemicals on clothes: If chemicals spill on clothes, the person should immediately remove the contaminated clothing and rinse the affected area with water.
4. Cuts or minor burns: For cuts or minor burns, it is important to have a first aid kit readily available. Clean the wound with soap and water, apply an antiseptic ointment, and cover it with a sterile bandage.
5. Chemicals in eyes: If chemicals get into someone's eyes, they should flush their eyes with water for at least 15 minutes using the eyewash station in the laboratory.
