Appropriate engineering controls :
Good general ventilation should be sufficient to control worker
exposure to airborne contaminants.
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 modifications to the process equipment will be
necessary to reduce emissions to acceptable levels.
Individual protection measures
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.
Eye/face protection :
Safety eyewear complying with an approved standard should be used
when a risk assessment indicates this is necessary to avoid exposure to
liquid splashes, mists, gases or dusts. If contact is possible, the
following protection should be worn, unless the assessment indicates a
higher degree of protection: chemical splash goggles.
Skin protection
Hand protection :
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
