Answer 1

Floor drains in a lab can be either blocked or maintained with liquid to prevent gases and microbial growth.

Step-by-step explanation:

Floor drains in a lab setting can be either blocked or maintained with sufficient liquid in the trap to prevent gases from escaping or microbial growth. This is important to ensure the safety and cleanliness of the lab environment. Chemical drain cleaners, which are available in solid or liquid form, can be used to maintain the drains and prevent clogs. These cleaners are often used by licensed plumbers.
