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. Reference
should be made to appropriate monitoring standards. Reference to national
guidance documents for methods for the determination of hazardous
substances will also be required.
Engineering measures
:
No special ventilation requirements. Good general ventilation should be
sufficient to control worker exposure to airborne contaminants. If this
product contains ingredients with exposure limits, use process enclosures,
local exhaust ventilation or other engineering controls to keep worker
exposure below any recommended or statutory limits.
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.
Personal protection
Respiratory
:
Use a properly fitted, particulate filter 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.
Hands
:
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. Considering the parameters
specified by the glove manufacturer, check during use that the gloves are
still retaining their protective properties. It should be noted that the time to
breakthrough for any glove material may be different for different glove
manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.
Eyes
:
Protective eyewear is not required, but may be used in situations were
contact is expected.
Skin
:
No special protective clothing is required.
Environmental exposure
controls
:
Emissions from ventilation or work process equipment should be checked
to ensure they comply with the requirements of environmental protection
legislation. In some cases, fume scrubbers, filters or engineering
