8.2. Exposure controls
8.2.1. Engineering controls
Use general dilution ventilation and/or local exhaust ventilation to control airborne exposures to below relevant Exposure
Limits and/or control dust/fume/gas/mist/vapors/spray. If ventilation is not adequate, use respiratory protection equipment.
8.2.2. Personal protective equipment (PPE)
Eye/face protection
Select and use eye/face protection to prevent contact based on the results of an exposure assessment. The following eye/face
protection(s) are recommended:
Full Face Shield
Indirect Vented Goggles
Skin/hand protection
Select and use gloves and/or protective clothing approved to relevant local standards to prevent skin contact based on the
results of an exposure assessment. Selection should be based on use factors such as exposure levels, concentration of the
substance or mixture, frequency and duration, physical challenges such as temperature extremes, and other use conditions.
Consult with your glove and/or protective clothing manufacturer for selection of appropriate compatible gloves/protective
clothing.
Gloves made from the following material(s) are recommended: Butyl Rubber
Select and use body protection to prevent contact based on the results of an exposure assessment. The following protective
clothing material(s) are recommended: If this product is used in a manner that presents a higher potential for exposure (eg.
spraying, high splash potential etc.), then use of protective coveralls may be necessary. Apron – Butyl rubber
Respiratory protection
An exposure assessment may be needed to decide if a respirator is required. If a respirator is needed, use respirators as part of
a full respiratory protection program. Based on the results of the exposure assessment, select from the following respirator
type(s) to reduce inhalation exposure:
Half facepiece or full facepiece air-purifying respirator suitable for organic vapors and particulates
For questions about suitability for a specific application, consult with your respirator manufacturer.
