8.2. Exposure Controls
Appropriate Engineering Controls: Emergency eye wash fountains and safety showers should be available in the immediate vicinity
of any potential exposure. Ensure adequate ventilation, especially in confined areas. Ensure all national/local regulations are
observed. Use explosion-proof equipment. Proper grounding procedures to avoid static electricity should be followed. Gas detectors
should be used when flammable gases or vapors may be released. Oxygen detectors should be used when asphixiating gases may be
released.
Personal Protective Equipment: Gloves. Protective clothing. Protective goggles. Insufficient ventilation: wear respiratory protection.
High vapor/gas concentration: self-contained respirator.
Materials for Protective Clothing: Chemically resistant materials and fabrics. Wear fire/flame resistant/retardant clothing.
Hand Protection: Wear protective gloves. If material is cold, wear thermally resistant protective gloves.
Eye Protection: Chemical safety goggles.
Skin and Body Protection: Wear suitable protective clothing.
Respiratory Protection: Use a NIOSH-approved self-contained breathing apparatus whenever exposure may exceed established
Occupational Exposure Limits. In case of inadequate ventilation, oxygen deficient atmosphere, or where exposure levels are not
known wear a self-contained breathing apparatus (SCBA).
Thermal Hazard Protection: Wear thermally resistant protective clothing.
