Exposure Controls & Personal Protective Equipment

Occupational exposure limits, engineering controls, and required safety equipment

Engineering Controls

Consider a work permit system e.g. for maintenance activities. Ensure adequate air ventilation. Provide adequate general and local exhaust ventilation. Keep concentrations well below lower explosion limits. Gas detectors should be used when quantities of flammable gases or vapours may be released. Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure limit is not exceeded. Systems under pressure should be regularly checked for leakages. Product to be handled in a closed system. Only use permanent leak tight installations (e.g. welded pipes). Take precautionary measures against static discharges.

Hand Protection

Wear working gloves while handling containers Guideline: EN 388 Protective gloves against mechanical risks.

Eye Protection

Safety eyewear, goggles or face-shield to EN166 should be used to avoid exposure to liquid splashes. Wear eye protection to EN 166 when using gases. Guideline: EN 166 Personal Eye Protection.

Respiratory Protection

Not required.

Skin/Body Protection

Wear fire/flame resistant/retardant clothing. Guideline: ISO/TR 2801:2007 Clothing for protection against heat and flame -- General recommendations for selection, care and use of protective clothing. Wear safety shoes while handling containers Guideline: ISO 20345 Personal protective equipment - Safety footwear.

Environmental Exposure Controls
