Use respiratory protection unless adequate local exhaust
ventilation is provided or exposure assessment demonstrates
that exposures are within recommended exposure guidelines.
The filter class for the respirator must be suitable for the maximum expected contaminant concentration(gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, selfcontained breathing apparatus must be used.

Hand protection:

Chemical-resistant, impervious gloves complying with anapproved standard should be worn at all times when handlingchemical products if a risk assessment indicates this is necessary.

Eye protection:

Safety eyewear complying with an approved standard should
be used when a risk assessment indicates this is necessary.

Skin and body protection:

Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place.
