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.
