When University employees are exposed or potentially exposed to hazardous air contaminants, the primary method of protection is through use of accepted engineering methods such as local exhaust ventilation, elimination of the hazardous substance, or isolating the contaminant process. However, when these control methods are infeasible, or if they fail to reduce the exposure to acceptable levels, respirators will be provided to and worn by employees.
Respirators are personal protection equipment (PPE) designed to cover the nose and mouth and works by removing air contaminants, or by providing clean air to the user.
Proper use of a respirator is essential to the health of the user, therefore everyone that wears a respirator, must be included in the University of Minnesota Respirator Protection Program (RPP).
University Health and Safety is responsible for the written RPP to ensure it is up-to-date and effective.
Services We Provide
- Hazard evaluation and determination of the need for respiratory protection
- Recommendations for the appropriate respirator, cartridges, and filters that provide the appropriate level of protection
- Fit testing
- Training and instruction on the proper use and maintenance of respirators
Preparation for Using a Respirator
There are several steps to be completed before you may use a respirator. Complete the following steps:
- Contact Industrial Hygiene for a Consultation and Hazard Assessment
In a hazard assessment, our staff will identify the contaiminant properties and evaluate the potential exposure against regulatory personal exposure limits (PELS), or threshold limit values (TLVs). Staff will then determine if an exposture is at the level that may cause harm. Call (612) 626-6002 to schedule a consultation.
- Respiratory Protection Program: Medical Evaluation and Fit Testing
Wearing a respirator may place a burden on your cardiovascular system while your are working. Therefore, prior to fit testing and respirator use, each person is required to have a medical evaluation. Visit the Occupational Health Process for Respirator Medical Clearance website to start the process.
- Respirators and Cartridge Selection
When a respirator is required in the workplace, all respirators must be approved by the National Institute for Occupational Safety and Health (NIOSH). Additionally, each respirator must be selected to provide a level of protection necessary for health and safety. Information about the different types of respirators and their assigned protection factors is available in the OSHA Assigned Protections Factors for the Revised Respiratory Protection Standard.
Chemical cartridges do not last forever. If the cartridge does not have an End-of-Service-Life Indicator (ESLI), then a change-out schedule must be developed and followed. Cartridge service life is based upon environmental factors such as temperature, humidity, and the amount of physical effort required during the work task. Contact University Health and Safety (UHS) for assistance at email@example.com or (612) 626-6002.
For information on Voluntary Use of Respirators, see the N 95 Voluntary Use Fact Sheet.
- Respiratory Protection Training
The Respiratory Protection Training course is required for anyone who is required to wear any type of respirator, including N-95 filtering facepieces, for any reason, regardless of duration or frequency of use. The training is also strongly recommended for anyone who wears any type of respirator voluntarily.
