HCL, ANHYDROUS GAS - ELECTRONIC GRADE

SECTION 2: Hazards identification

EMERGENCY OVERVIEW ************************************************************************ * Liquified gas. Sharp odor. Causes severe eye burns. Liquid causes* * frost burns. Causes severe skin burns. May be fatal if inhaled. * * Causes respiratory tract irritation. May cause lung injury. * ************************************************************************

Potential health effects

See Section 11 for toxicological data.) EYE: May cause pain. May cause severe irritation with corneal injury which may result in permanent impairment of vision, even blindness. Vapors may cause lacrimation (tears). SKIN: If liquid contacts skin, evaporation may cause frost-bite type injury due to rapid cooling. (liquified gas under pressure) Short single exposure may cause severe skin burns. (HCL in contact with moisture, including water solutions). A single prolonged exposure is not likely to result in the material being absorbed through skin in harmful amounts. INGESTION: Ingestion is unlikely due to physical state. INHALATION: A single brief (minutes) inhalation exposure to easily attainable concentrations may cause serious adverse effects, even death. Excessive exposure may cause severe (Continued on page 2 , over) ------------------------------------------------------------------------ irritation to upper respiratory tract and lungs. Excessive exposure may cause lung injury. SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Repeated excessive exposures may cause erosion of teeth and bleeding and ulceration of nose, mouth and gums.

Cancer information

Did not cause cancer in long-term animal studies. An epidemiology study of workers did not show any association between HCl exposure and lung cancer. TERATOLOGY (BIRTH DEFECTS): No relevant information found. REPRODUCTIVE EFFECTS: No relevant information found.
