Using Coated or Shatter-Resistant Light Bulbs to Prevent Physical Contamination

Why is it important to use coated or shatter-resistant light bulbs?

Coated or shatter-resistant light bulbs help prevent physical contamination by containing glass fragments if the bulb breaks, ensuring they don't become a physical hazard. These types of light bulbs are specifically designed to minimize the risk of contamination in various settings.

What type of contamination do coated or shatter-resistant light bulbs prevent?

a) Biological

b) Physical

c) Chemical

d) Microbiological

Final answer:

Coated or shatter-resistant light bulbs help prevent physical contamination by containing glass fragments if the bulb breaks, ensuring they don't become a physical hazard.

Explanation:

Using coated or shatter-resistant light bulbs is a way of preventing physical contamination. This type of bulb is designed to help contain fragments if the glass is broken, thereby avoiding the contamination of the environment, whether it be in a kitchen or a laboratory.

The key purpose of using shatter-resistant bulbs is to prevent glass from becoming a physical hazard, not necessarily to inhibit biological, chemical, or microbiological contaminants, which are substances that can cause harm through biological activity, chemical reactions, or the presence of microorganisms, respectively.

Therefore option b is the correct answer.
