What must be done before using a respirator for the first time?

Before using a respirator for the first time, it is essential to request a fit test. A fit test is a crucial step in ensuring that the respirator provides an adequate seal on the face. This seal is necessary to prevent contaminants from entering the breathing space, which is particularly important in environments where asbestos or other hazardous materials are present.

The fit test involves assessing how well the respirator conforms to the wearer’s face and ensuring that there are no gaps through which air can leak. Achieving the right fit not only enhances the effectiveness of the respirator but also increases the comfort for the wearer, allowing for prolonged use without significant discomfort.

While reading the user manual and inspecting the respirator are certainly important steps for the safe use and maintenance of the equipment, they do not directly address the primary concern of ensuring a proper seal to protect against airborne hazards. Similarly, assuming a respirator is ready to use without a fit test can lead to inadequate protection, which could expose the worker to serious health risks associated with inhaling harmful substances. Therefore, requesting a fit test is the most critical first step in the safe and effective use of a respirator.
