Question

you work in a laboratory facility. someone is conducting experiments in the next lab. you hear a noise that sounds like \pop,\ followed by the crash of glass. as you approach the lab door, you notice a foul smell coming from under the door. you shout through the closed door but get no answer. you call 9-1-1 or the designated emergency number. what should you do next?

○ wait for emergency medical services (ems) personnel to arrive. do not enter the room because the fumes might be harmful to you.

○ clean up any broken glass you might find on the floor.

○ enter the room to check for the origin of the foul odor.

○ give first aid until help arrives.

Explanation:

In a lab emergency with unknown fumes (foul smell) and potential hazards, entering the room (to check odor or clean glass) or giving first aid without proper gear/knowledge is unsafe. Waiting for EMS and avoiding entry protects you from harmful fumes, as lab fumes can be toxic. The other options risk exposure or improper response.

Answer:

A. Wait for emergency medical services (EMS) personnel to arrive. Do not enter the room because the fumes might be harmful to you.
