🏭 Engineering Controls
Properly operating chemical fume hood designed for hazardous chemicals and having an average face velocity of at least 100 feet per minute.
🧤 Hand Protection
Impervious gloves. Check protective gloves prior to each use for their proper condition. The selection of suitable gloves not only depends on the material, but also on quality. Quality will vary from manufacturer to manufacturer. Material of gloves Nitrile rubber, NBR. Penetration time of glove material (in minutes) 480. Glove thickness: 0.11 mm
👁️ Eye Protection
Tightly sealed goggles. Full face protection. Safety glasses with side shields / NIOSH (US) or EN 166(EU)
😷 Respiratory Protection
Respiratory protection equipment should be worn and maintained according to the suppliers specifictions. Fit testing must be conducted at regular intervals. Use self-contained respiratory protective device in emergency situations. Recommended filter device for short term use: Use a respirator with type P100 (USA) or P3 (EN 143) cartridges as a backup to engineering controls. Risk assessment should be performed to determine if air-purifying respirators are appropriate. Only use equipment tested and approved under appropriate government standards.
🦺 Skin/Body Protection
Protective work clothing.
