Using Coated or Shatter-Resistant Light Bulbs to Prevent Contamination

What contamination does using coated or shatter-resistant light bulbs prevent?

a) Chemical contamination
b) Physical contamination
c) Biological contamination
d) All of the above

Final answer:

Coated or shatter-resistant light bulbs prevent physical contamination by containing fragments if broken, which is important in maintaining contaminant-free areas.

Explanation:

Using coated or shatter-resistant light bulbs prevents physical contamination. These bulbs are designed to remain intact on impact or to contain the fragments if broken, thereby eliminating the risk of glass shards and other debris that can contaminate the surrounding area. This is particularly important in food service settings, manufacturing plants, and any environment where maintaining a contaminant-free area is crucial. These bulbs are designed to contain the glass if they break, reducing the risk of injury from sharp glass fragments. They can also prevent chemical contamination to some extent by not releasing hazardous substances when they break or overheat.
