What term is used to describe when a respirator should be disposed of?

Retention period
Service life
Replacement schedule
Life span

The correct answer is: Service life

The term that describes when a respirator should be disposed of is known as "service life." This concept refers to the duration that a respirator is effective for its intended use, after which it may no longer provide the necessary level of protection. Factors such as usage, the type of respirator, and the environment it is used in can all affect its service life. Understanding service life is critical for ensuring worker safety, as using a respirator beyond its effective period can lead to a false sense of security, resulting in inadequate protection against harmful airborne contaminants. Proper training and adherence to manufacturer guidelines help in assessing the appropriate time to dispose of or replace respirators to maintain optimal safety standards on construction sites.
