Whenever possible engineering controls or work duration shall be used to control employee exposure to hazardous airborne . Use of air purifying respirators or supplied air systems shall be a last resort choice.
Determination for respiratory need will be done by EH&S when requested by either the employee or the supervisor.
In order for an employee to use any respirator (other than a dust mask) in a hazardous atmosphere they must:
Be medically cleared by a physician
Be annually fit tested to the respirator
Be annually trained on the care and use of that respirator.
Respirator purchases must be pre-approved in writing by EH&S
the only exception to this policy is when an employee is not required to wear a respirator to protect them from a hazardous atmosphere, that employee may choose to voluntarily wear a respirator. In this case the employee supplies the respirator.
