Hydrogen Chloride is a colorless to slight yellow corrosive gas with a pungent irritating odor. Although not considered a combustible gas, it may react or form combustible compounds when contact is made with alcohol and hydrogen cyanide or with aluminum-titanium alloys. Dissolving Hydrogen Chloride in water will yield a strong highly corrosive acid. It is for this reason that HCl is a strong irritant to the eyes, nose, and upper respiratory tract. Levels of 35 ppm can cause irritation to the throat even after a very short period of time.

Effects of Various HCl Levels 

 Hydrogen Chloride Level in PPM             Resulting Conditions on Humans

.25                                                  Odor threshold

5                                                     Permissible Exposure Limit (PEL)

35                                                  Irritation to the eyes, nose, throat even after a short period of time.

50                                                 Immediately Dangerous to Life and Health (IDLH)

1,300-2,000                                 Death in 2-3 minutes
