Nonspecific Symptoms: Irritation or burns of bodily tissues; other symptoms of exposures.
First Md for Inhalation: Remove victim to fresh air and keep warm and at rest. If breathing becomes difficult or if
breathing stopped, administer aftificial respiration. Get medical attention immediately. (Caution: Administration of
mouth-to-mouth resuscitation may expose the first aid provider to chemical within the victim's lungs or vomit.)
First Aid for Skin and Eye Contact: Flush eyes immediately with water for at least 15 minutes, occasionally lifting
eyelids. Remove all contaminated clothing. Wash affected body areas with large amounts of water. Get medical
attention immediately if eye contact has occurred or if skin irritation persists after washing.
First Md for In ges don: Do not induce vomiting. Keep victim warm and at rest. Get medical attention immediately.
FIRE RESPONSE
Extinguishing Materials: As necessary for surrounding fire, including dry chemical, carbon dioxide, foam, water
spray or fog.
Extinguishing Techniques: Unusual toxic vapor hazard. Material reacts relatively slowly with water to form
corrosive but less hazardous product. Stay upwind. Avoid all bodily contact. Wear breathing apparatus and
appropriate protective clothing. Move container from fire area if no risk. Use water from side and safe distance to
keep fire exposed containers. Be alert to the possibility that containers may rupture violently in a fire; they do not
have pressure relief devices of any kind. For massive fire in cargo area, use unmanned hose holder or monitor
nozzles.
SPILL RESPONSES
General In forma don: Restrict access to area. Keep unprotected personnel upwind of spill area. Avoid contact with
spilled product. Protect sewers and waterways from contaminated runoff. Notify proper authorities, downstream
sewer and water treatment operations, and other downstream users of potentially contaminated water. Note that
intake of highly contaminated water may result in damage to boilers or industrial process equipment. Choose
equipment, where possible, that is not corroded or otherwise damaged by the spilled product and the acid formed in
contact with water. Take the high volatility, extreme toxicity, and heavier-than-air nature of phosgene into account
`ii when planning the response.
AIR SPILL
TECHNIQ UE
EVACUATION ... Evacuate local and downwind areas as conditions warrant to prevent public exposure and to allow
vapors or fumes to dissipate. Phosgene spills may expose downwind areas to toxic concentrations over considerable
distances in some cases.
CONSEQ UENCE
Need to notify, organize, transport and house displaced persons.
MITIGATION
Stop leak if without risk and if proper equipment available. Allow vapors and fumes to dissipate completely
before reentering spill area without special protective gear. Consult qualified experts for assistance.
TECHNIQ UE
WATER FOG OR SPRAY ... Water fog or spray applied to phosgene vapors or fumes may accelerate their dispersal
in the atmosphere. Do not apply water directly to the leak area since the resulting increased corrosivity of phosgene
may cause a larger leak. Do not apply water warmer than 450F to liquid phosgene pools since this may cause an
increase in vapor evolution.
CONSEQUENCE
Water runoff may contain a small amount (if any) of phosgene or hydrochloric acid from contact with airborne
vapors or fumes.
__ MI TI GA TION
Contain contaminated water and remove or neutralize as soon as possible to prevent spread of contamination.
Be alert to conditions such as fire hose runoff or rainwater that may add to spill volume and overfill
impoundments.
