No information known.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Properly operating chemical fume hood designed for hazardous chemicals and having an average face velocity of at least 100 feet per minute.
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) 480. Glove thickness 0.3 mm.
Tightly sealed goggles. Full face protection.
Use self-contained respiratory protective device in emergency situations. Recommended filter device for short term use: Use a respirator with organic vapor/acid gas 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 such as NIOSH (USA) or CEN (EU).
Protective work clothing.
