Preventing Contamination with Coated and Shatter Resistant Light Bulbs

How can coated or shatter resistant light bulbs help prevent contamination?

Choose the correct option:

1. Physical contamination

2. Chemical contamination

3. Biological contamination

Answer:

1. Physical contamination

Explanation:

Coated or shatter resistant light bulbs are utilized to prevent physical contamination. These types of light bulbs, especially CFL (Compact Fluorescent Light) and traditional fluorescent bulbs, contain mercury, which is a hazardous substance. Should the bulb shatter, it can release mercury or cause injuries due to sharp fragments. However, using coated bulbs can reduce these risks by containing the mercury within the coating even if the bulb breaks.

Aside from mercury, shattered bulbs can also pose a risk of physical harm or damage from sharp pieces. By using shatter resistant or coated light bulbs, these accidents and physical contaminations can be prevented.
