Why should polyester clothes be avoided in chemical laboratories?

Options

A. They tear easily
B. They catch fire easily
C. They get stained easily.
D. They absorb high amounts of water

Explanation

### Step-by-Step Solution:

1. **Understanding Polyester**: Polyester is a type of synthetic fiber made from a chemical reaction between an alcohol and an acid. The key component in polyester is the ester linkage, which is characterized by the presence of a carbonyl group (C=O) bonded to an oxygen atom (O).

2. **Properties of Polyester**: One of the significant properties of polyester is that it is highly flammable. This means that when exposed to heat or flames, polyester can easily catch fire and burn rapidly.

3. **Risks in Chemical Laboratories**: Chemical laboratories often involve the use of various chemicals, some of which may be volatile or reactive. In such environments, the risk of fire is heightened due to the presence of flammable substances.

4. **Conclusion**: Because polyester is highly flammable, wearing polyester clothing in a chemical laboratory poses a significant safety risk. If a fire were to occur, polyester clothes could ignite quickly, leading to severe burns or injuries.

5. **Final Answer**: Therefore, polyester clothes should be avoided in chemical laboratories because they catch fire easily due to their flammable nature.
