You are probably exposed to some level of dust in your workplace, dust that may pose a variety of health hazards. If those hazards are significant enough, your employer will require that you use respiratory protection. If the hazards are minor and protection is not mandated, you can choose to wear a dust mask. This course will explain how to select, use and care for dust masks. Ideal learners are employees in the heavy equipment, manufacturing (production and maintenance), construction and mining industries, and their supervisors.
