Exposure controls
Engineering
Measures/Controls
•
Adequate ventilation systems as needed to control concentrations of airborne
contaminants below applicable threshold limit values.
Personal Protective Equipment
Pictograms
•
Respiratory
•
If airborne dust is present or in case of inadequate ventilation, use appropriate
respiratory protection. Use of half/full face air purifying or N95 dust mask is
recommended.
Eye/Face
•
Wear safety glasses.
Hands
•
Wear appropriate gloves.
Skin/Body
•
If prolonged exposure is anticipated, it is recommended for handlers to wear
appropriate clothing to prevent skin contact. Use full body suit such as Tyvek or
Tychem suit is recommended.
