🏭 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 Butyl rubber, BR. Penetration time of glove material (in minutes) Not determined.
👁️ Eye Protection
Tightly sealed goggles. Full face protection. Safety glasses with side shields / NIOSH (US) or EN 166(EU).
😷 Respiratory Protection
Use self-contained respiratory protective device in emergency situations. Recommended filter device for short term use: Use a respirator with multi-purpose combination (US) or type ABEK (EN 14387) 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 such as NIOSH (USA) or CEN (EU).
