Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location.
Protective gloves. Neoprene (Breakthrough time: > 480 minutes, Thickness: 0.45 mm, EU standard: Level 6 EN 374). Nitrile rubber (Breakthrough time: > 480 minutes, Thickness: > 0.2 mm). Inspect gloves before use. Observe instructions regarding permeability and breakthrough time. Ensure gloves are suitable for the task. Remove gloves with care avoiding skin contamination.
Wear safety glasses with side shields (or goggles) (European standard - EN 166)
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. Large scale/emergency use: Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended Filter type: Particle filter. Small scale/Laboratory use: Maintain adequate ventilation.
Long sleeved clothing.
Prevent product from entering drains.
