Exposure Controls & Personal Protective Equipment (PPE)

Occupational exposure limits, engineering controls, and required safety equipment

๐Ÿญ Engineering Controls

Properly operating chemical fume hood designed for hazardous chemicals and having an average face velocity of at least 100 feet per minute.

๐Ÿงค 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

๐Ÿ‘๏ธ Eye Protection

Safety glasses with side shields / NIOSH (US) or EN 166(EU)

๐Ÿ˜ท Respiratory Protection

Use suitable respirator when high concentrations are present. Recommended filter device for short term use: Use a respirator with type N95 (USA) or PE (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.
