No biological exposure limits noted for the ingredient(s).
Biological limit values
Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates
should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation,
or other engineering controls to maintain airborne levels below recommended exposure limits. If
exposure limits have not been established, maintain airborne levels to an acceptable level.
Appropriate engineering
controls
Individual protection measures, such as personal protective equipment
Wear safety glasses with side shields (or goggles).
Eye/face protection
Skin protection
Impervious gloves. Confirm with reputable supplier first.
Hand protection
Wear appropriate chemical resistant clothing. Use of an impervious apron is recommended. As
required by employer code.
Other
Where exposure guideline levels may be exceeded, use an approved NIOSH respirator.
Respirator should be selected by and used under the direction of a trained health and safety
professional following requirements found in OSHA's respirator standard (29 CFR 1910.134),
CAN/CSA-Z94.4 and ANSI's standard for respiratory protection (Z88.2).
Respiratory protection
Not applicable.
Thermal hazards
Always observe good personal hygiene measures, such as washing after handling the material
and before eating, drinking, and/or smoking. Routinely wash work clothing and protective
equipment to remove contaminants. Contaminated work clothing should not be allowed out of the
workplace. When using do not eat or drink.
