If user operations generate dust, fumes, gas, vaporor mist, use process enclosures, local exhaust ventilation or other engineering controlsto keep worker exposure to airborne contaminants below any recommended or statutorylimits.: Wash hands, forearms and face thoroughly after handling chemical products, beforeeating, smoking and using the lavatory and at the end of the working period. Appropriatetechniques should be used to remove potentially contaminated clothing. Washcontaminated clothing before reusing. Ensure that eyewash stations and safety showersare close to the workstation location.:::Exposure limits9. Physical and chemical propertiesPhysical stateColorOdorDistributionMelting/freezing point :VOC content :SolubilityUse a properly fitted, air-purifying or air-fed respirator complying with an approvedstandard if a risk assessment indicates this is necessary. Respirator selection must bebased on known or anticipated exposure levels, the hazards of the product and the safeworking limits of the selected respirator.Chemical-resistant, impervious gloves complying with an approved standard should beworn at all times when handling chemical products.Safety eyewear complying with an approved standard should be used when a riskassessment indicates this is necessary to avoid exposure to liquid splashes, mists ordusts. If operating conditions cause high dust concentrations to be produced, use dustgoggles.Personal protective equipment for the body should be selected based on the task beingperformed and the risks involved and should be approved by a specialist before handlingthis product.: Emissions from ventilation or work process equipment should be checked to ensure theycomply with the requirements of environmental protection legislation. In some cases,fume scrubbers, filters or engineering modifications to the process equipment will benecessary to reduce emissions to acceptable levels.: Solid.
