Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Handle under dry protective gas. Keep container tightly sealed. Keep away from heat and direct sunlight. Ensure good ventilation at the workplace. Open and handle container with care.
Refrigerate. Store away from air. Protect from heat.
Protect against electrostatic charges. Keep ignition sources away.
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 Fluorocarbon rubber (Viton). Penetration time of glove material (in minutes) 480. Glove thickness: 0.7 mm.
Tightly sealed goggles. Full face protection. Safety glasses with side shields / NIOSH (US) or EN 166(EU).
Use suitable respirator when high concentrations are present. Recommended filter device for short term use: Use a respirator with multi-purpose combination (US) or type AXBEK (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).
Protective work clothing.
