Protective Equip. / Clothing

Eye/face 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).

Skin protection: Handle with gloves.

Body Protection: Complete suit protecting against chemicals. Flame retardant antistatic protective clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.

Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multipurpose 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).

Employees should be provided with & required to use impervious clothing, gloves, face shields (eight-inch minimum), and other appropriate protective clothing necessary to prevent repeated or prolonged skin contact with liquid 1,1-dichloroethane. ... Employees should be provided with and required to use splash-proof safety goggles, where liquid 1,1-dichloroethane may contact the eyes.

Wear appropriate personal protective clothing to prevent skin contact.

Wear appropriate eye protection to prevent eye contact.

APF = 50 Any supplied-air respirator with a full facepiece.

Respirator Recommendations: Emergency or planned entry into unknown concentrations or IDLH conditions:

Assigned Protection Factor (APF) Respirator Recommendations
APF = 10,000 Any self-contained breathing apparatus that has a full facepeice and is operated in a pressure-demand or other positive-pressure mode.
APF = 10,000 Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus.

Respirator Recommendations: Escape:

Assigned Protection Factor (APF) Respirator Recommendations
APF = 50 Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted organic vapor canister./ Any appropriate escape-type, self-contained breathing apparatus.

Wear solvent-resistant protective gloves and clothing to prevent any reasonable probability of skin contact. ... Teflon is among the recommended protective materials. ... Contact lenses should not be worn when working with this chemical. Wear splash-proof chemical goggles and face shield unless full face-piece respiratory protection is worn. Employees should wash immediately with soap when skin is wet or contaminated. Provide emergency showers and eyewash.
