Acrylonitrile

CAS RN:107-13-1

Protective Equipment / Clothing

Wear special protective clothing and positive pressure self-contained breathing apparatus. Butyl rubber barrier recommended.

... Personal respiratory protection preferably of positive pressure type & impermeable protective clothing is necessary when there is possibility of exposure resulting from normal but nonroutine operation such as pump replacement. Respiratory protective equipment, protective clothing & fire fighting equipment must be available for emergency use.

Air-supplied mask, industrial chemical type, with approved canister for acrylonitrile in low (less than 2%) concentrations; rubber or plastic gloves; cover goggles or face mask; rubber boots; slicker suit; safety helmet.

PRECAUTIONS FOR "CARCINOGENS": ... Dispensers of liq detergent /should be available./ ... Safety pipettes should be used for all pipetting. ... In animal laboratory, personnel should ... wear protective suits (preferably disposable, one-piece & close-fitting at ankles & wrists), gloves, hair covering & overshoes. ... In chemical laboratory, gloves & gowns should always be worn ... however, gloves should not be assumed to provide full protection. Carefully fitted masks or respirators may be necessary when working with particulates or gases, & disposable plastic aprons might provide addnl protection. ... Gowns ... /should be/ of distinctive color, this is a reminder that they are not to be worn outside the laboratory. /Chemical Carcinogens/

Wear appropriate personal protective clothing to prevent skin contact.

Wear appropriate eye protection to prevent eye contact.

Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection.

Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.]

Respirator Recommendations: At concentrations above the NIOSH REL, or where there is no REL, at any detectable concentration:

Assigned Protection Factor (APF) Respirator Recommendations
APF = 10,000 Any self-contained breathing apparatus that has a full facepiece 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.

Personnel protection: Wear positive pressure self-contained breathing apparatus. Wear appropriate chemical protective clothing.

Respirator Recommendations: Escape Conditions:

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.
