Question

if a laboratory fire erupts, immediately * notify your instructor. run for the fire extinguisher. throw water on the fire. open the windows. approved eye protection devices (such as goggles) are worn in the laboratory to avoid eye strain to improve your vision only if you dont have corrective glasses any time chemicals, heat or glassware are used

Explanation:

• For the first question: In a laboratory fire, the instructor should be notified immediately as they have the training and knowledge to handle the situation properly. Running for a fire extinguisher might be part of the response but not the first step without proper guidance. Throwing water can be dangerous (e.g., if the fire involves electrical equipment or certain chemicals). Opening windows can fan the flames.
• For the second question: Approved eye protection (like goggles) is worn any time chemicals, heat, or glassware are used to protect the eyes from potential splashes, fumes, or breakage. Eye strain is not the main reason. They are not for vision improvement. And they are required regardless of having corrective glasses (in fact, some goggles can be worn over glasses).

Answer:

First question: notify your instructor.
Second question: any time chemicals, heat or glassware are used.
