8.3 Individual protection measures, such as personal protective equipment (PPE)
Eye/face protection
Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH
(US) or EN 166(EU).
Skin protection
Wear chemical resistant gloves and clothing.
Body protection
Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the
specific work-place., The type of protective equipment must be selected according to the concentration and amount
of the dangerous substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multipurpose
combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the
respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components
tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
