Engineering controls and safe work practices are the primary means to prevent employee over exposure to chemicals. However, when these controls are not feasible or available, then wearing a respirator may be necessary. Employees who wear a respirator must be given prior approval by the EHSC. Before a respirator is issued, a workplace assessment is conducted to identify harmful airborne chemicals. If respiratory protection is recommended, the employee will undergo medical approval, training and fit testing. Medical approval, either by physical exam or confidential medical questionaire, is needed for first time respirator users and according to guidelines for current respirator users. These guidelines also pertain to N-95 respirator use.

Each department that uses respirators, including self contained breathing apparatus (SCBA), must have a written protocol. The protocol must be incorporated into the safety plan.The department's written program must discuss hazards unique to their work area. Please be aware that two persons need to be qualified to use SCBA in order for SCBA to be used in the workplace.


To provide for the protection of North Carolina State University employees from over exposure to chemicals in the workplace according to OSHA Standard 29CFR1910.134.
