Hazard Monitoring

Substances with a PEL

If engineering controls will not be used to control exposures and the substance has a Permissible Exposure Limit (PEL), contact EHS for guidance before using the substance. Air monitoring may be necessary to ensure that OSHA limits are not exceeded.

When air samples are taken, the costs associated with lab analysis and sampling media will usually be covered by EHS. Depending on the number of samples, your department may be asked to support part of the expenses. If air monitoring has been conducted by EHS, employees will be notified in writing of the results within 15 working days after EHS receives the results from the analytical laboratory. If many employees have been affected, the notification requirement may be met by posting the results in an appropriate area.

Hazard Controls

If exposure monitoring reveals that a regulatory limit has been exceeded, EHS will work with your department to identify suitable engineering and administrative controls. If implementation of these controls is not sufficient to decrease the employee's exposure, respiratory protection options will be examined. All employees required to use respirators must be enrolled in the Respiratory Protection Program and be offered medical surveillance through EHS' Occupational Health Assurance Program (OHAP). Respirator fit testing and employee training must be performed before the employee is assigned a respirator for use.

Employees using dust masks must contact EHS to receive additional information on the limitation of these masks and to complete a Respiratory Hazards Assessment Form.
