Which of the following is not a required element of a respirator maintenance program?

The selection and purchase of respirators is indeed a critical part of overall respiratory protection programs, but it is not classified as a required element of the maintenance program itself. A respirator maintenance program focuses specifically on the aspects that ensure respirators remain in good working condition and continue to provide adequate protection to the user.

Regular inspections are essential to identify any signs of damage or wear that could compromise the effectiveness of the respirator. Cleaning and disinfecting are necessary to prevent contamination and ensure the safety and comfort of users, especially if the respirator is used repeatedly. Storage and repair are also key components, as proper storage prevents damage from environmental conditions and repairs are needed to maintain the integrity of the device over its lifespan.

In contrast, while selection and purchase are foundational activities when implementing a respiratory protection program, they do not fall under the maintenance activities required after the respirators are in service.
