Exposure controls/personal protection
Product name Exposure limits
Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
Personal protection
Respiratory :
Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary.
Hands :
8 .
Engineering measures :
Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits. The engineering controls also need to keep gas, vapor
or dust concentrations below any lower explosive limits. Use explosion-proof ventilation
equipment.
Hygiene measures :
Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period. Appropriate
techniques should be used to remove potentially contaminated clothing. Wash
contaminated clothing before reusing. Ensure that eyewash stations and safety showers
are close to the workstation location.
Recommended monitoring
procedures
:
If this product contains ingredients with exposure limits, personal, workplace atmosphere
or biological monitoring may be required to determine the effectiveness of the ventilation
or other control measures and/or the necessity to use respiratory protective equipment.
