<br />1 ppm = 1.40 mg/m3
<br />Colorless gas with a strong odor of rotten
<br />eggs. Eye, upper respiratory tract irritant.
<br />Exposure symptoms would include eye pain,
<br />discharge of tears, vision problems, dizziness,
<br />headache, weakness, and irritability.
<br />High concentrations (200+ppm) causes
<br />paralysis of sense of smell, (500+ppm)
<br />respiratory paralysis, collapse and coma,
<br />(>1000 ppm) can be fatal in minutes.
<br />Strongly corrosive to electrical connections
<br />and equipment; reacts with copper, oxidizing
<br />agents, nitric acid, soda lime, and peroxides;
<br />flammable gas, can build up in excavations
<br />and low lying areas .

<br />(127-18-4)
<br />1 ppm = 6.78 mg/m3
<br />Exposure Routes: inhalation, skin absorption,
<br />ingestion, skin and/or eye contact. Causes
<br />irritation of the eyes, nose, throat and rest of
<br />the respiratory system. Can cause nausea,
<br />flush face, dizziness, incoordination;
<br />headache, drowsiness; skin erythema (skin
<br />redness); liver damage (carcinogen). Target
<br />Organs: Eyes, skin, respiratory system, liver,
<br />kidneys, and central nervous system.

<br />fire to hydrogen chloride and phosgene.
