8.2 Exposure controls
Engineering Meāsures/Controls • Good general ventilation should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. Personal Protective Equipment Respiratory •  Follow the OSHA respirator regulations found in 29 CFR 1910.134. Use a NIOSH/MSHA approved respirator if exposure limits are exceeded or symptoms are experienced. •  Wear chemical splash safety goggles. Eye/Face Skin/Body • Wear appropriate gloves. Wear long sleeves and/or protective coveralls. Environmental Exposure Controls • Controls should be engineered to prevent release to the environment, including procedures to prevent spills, atmospheric release and release to waterways. Follow best practice for site management and disposal of waste. • An eyewash station and emergency shower must be available to the work station.
