Engineering Controls: No data available.
Personal Protective Equipment:
Provide easy access to water supply and eye wash facilities. Good general ventilation (typically 10 air changes per
hour) 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. If exposure limits have not
been established, maintain airborne levels to an acceptable level.
Eyes: Wear safety glasses with side shields (or goggles).
Skin: Wear suitable protective clothing. Wear chemical-resistant gloves, footwear, and protective clothing appropriate for the
risk of exposure. Contact health and safety professional or manufacturer for specific information.
Respiratory: In case of inadequate ventilation use suitable respirator. Seek advice from local supervisor.
Hygiene: Observe good industrial hygiene practices. Avoid contact with eyes. When using do not smoke. Contaminated work
clothing should not be allowed out of the workplace. Avoid contact with skin.
