How often must employees who are required to wear respirators be certified as medically fit?

Employees required to wear respirators must be certified as medically fit at least annually. This certification process is critical to ensure that individuals can safely use respiratory protection without risking their health. Respirators can place a physical burden on the wearer, potentially affecting their ability to breathe comfortably. The annual evaluation checks for physical condition changes that might impair a worker's ability to safely and effectively use a respirator, such as respiratory issues, cardiovascular health, or other medical conditions. This frequency assures that workers are fit for use of these devices and that their safety and health are not compromised while performing their duties.
