Question

1. what is the first thing you should always do in lab? type a response

Explanation:

In a laboratory (especially in scientific labs like those for Biology, Chemistry, Physics, etc.), safety is paramount. The first action typically involves ensuring personal safety by donning PPE to protect against potential hazards (chemical spills, biological agents, physical injuries) or orienting oneself with the lab's safety features (fire exits, eye wash stations, fire extinguishers) as per lab guidelines.

Answer:

Put on appropriate personal protective equipment (PPE), such as safety goggles, lab coat, and gloves (or follow the specific safety protocols and instructions given by the lab supervisor, like familiarizing yourself with the lab layout and safety equipment locations).
