Phosgene

CAS RN: 75-44-5

Other Preventive Measures

Immediate termination of exposure is essential and the/victim/ should be removed to fresh air. After exposure to liquid phosgene, contaminated clothing should be removed and disposed of. Exposed skin should be washed with large amounts of soap and water. If there was eye contact, the eyes should be flushed with copious amounts of water for at least 15 min.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
If material not involved in fire: Keep sparks, flames and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock down vapors.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
Evacuation: If fire becomes uncontrollable or container is exposed to direct flame-consider evacuation of one-third (1/3) mile radius. If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location and weather conditions.
Ventilation systems shall be designed to prevent the accumulation or recirculation of phosgene in the workroom, to maintain phosgene concentrations within the limits of the recommended standard, and to remove phosgene from the breathing zones of workmen. Exhaust ventilation systems shall discharge to the outside air through a sorption or a decomposition system (eg, scrubbers containing a alkaline scrubbing medium, such as 5% sodium hydroxide solution).
Control recommendations included replacement of equipment with improved hermetically sealed pumps and revamping of the makeup air system to provide uniform air supply at low velocities.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
The worker should immediately wash the skin when it becomes contaminated. /Liquid/
Work clothing that becomes wet or significantly contaminated should be removed and replaced. /Liquid/
