Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
🧤 Hand Protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Material: Fluorinated rubber. Minimum layer thickness: 0.7 mm. Break through time: 480 min. Material tested: Vitoject® (KCL 890 / Aldrich Z677698, Size M). Data source: KCL GmbH, test method: EN374. If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves.
👁️ Eye Protection
Face shield and safety glasses. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
😷 Respiratory Protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
🦺 Skin/Body Protection
Complete suit protecting against chemicals. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
🌍 Environmental Exposure Controls
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
