8. EXPOSURE CONTROLS/PERSONAL PROTECTION
MANUFACTURER'S RECOMMENDATION
It is prudent to reduce exposure to respirable dusts to the lowest attainable level through the use of engineering controls
such as ventilation and dust collection devices. Industrial hygiene standards and occupational exposure limits may vary
between countries, state and local jurisdictions. Contact your employer to determine which exposure levels apply to
your facility. If no regulatory dust or other standards apply, a qualified industrial hygienist can assist with a specific
workplace evaluation including recommendations for respiratory protection. In the absence of such guidance, the
manufacturer generally recommends the control of CMS wool exposures to 1 fiber/cc or less.
ENGINEERING CONTROLS
Use feasible engineering controls such as local exhaust ventilation, point of generation dust collection, down draft work
stations, emission controlling tool designs, and materials handling equipment designed to minimize airborne fiber
emissions.
PERSONAL PROTECTION EQUIPMENT
Skin Protection
Wear gloves, head coverings and full body clothing as necessary to prevent skin irritation. Washable or disposable
clothing may be used. If possible, do not take unwashed work clothing home. If soiled work clothing must be taken
home, employers should ensure employees are trained on the best practices to minimize or avoid non-work dust
exposure (e.g., vacuum clothes before leaving the work area, wash work clothing separately, rinse washer before
washing other household clothes, etc.).
Eye Protection
Wear safety glasses with side shields or other forms of eye protection in compliance with appropriate OSHA standards
to prevent eye irritation. The use of contact lenses is not recommended, unless used in conjunction with appropriate
eye protection. Do not touch eyes with soiled body parts or materials. If possible, have eye-washing facilities readily
available where eye irritation can occur.
Respiratory Protection
When it is not possible or feasible to reduce respirable dust exposures through engineering controls, employees are
encouraged to use good work practices together with respiratory protection. Comply with OSHA Respiratory Protection
Standards, 29 CFR 1910.134 and 29 CFR 1926.103, for the particular hazard or airborne concentrations to be
encountered in the work environment. For the most current information on respirator selection, contact your supplier.
