- SECTION IV - FIRE AND EXPLOSION DATA
- FLASH POINT: Nonflammable
- FLAMMABLE LIMITS:
- EXTINGUISHING MEDIA:
Water spray, dry chemicals, foam or carbon dioxide.
- SPECIAL FIRE-FIGHTING PROCEDURES:
When heated, hydrochloric acid releases hydrogen chloride gas. Use a
self-contained respirator if heating
- UNUSUAL FIRE-FIGHTING AND EXPLOSION HAZARDS:
Hydrochloric acid reacts with steel and many common metals to produce
hydrogen gas, which is highly
flammable and a fire and explosion hazard.
- SECTION V - REACTIVITY DATA
- STABILITY: Stable
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS OR MATERIALS TO AVOID:
Avoid contact with metals and sulfides. Contact with metals produces
flammable or explosive hydrogen.
Contact with metals releases poisonous hydrogen sulfide gas. Avoid contact
with bases or any other
- HAZARDOUS DECOMPOSITION PRODUCTS:
Hydrochloric acid is stable; however, highly corrosive hydrogen
chloride gas and hydrochloric acid vapor is
released at above boiling temperatures.
SECTION VI - HEALTH HAZARD DATA
- CARCINOGENIC LISTING:
NTP: No ingredients listed in this section.
IARC MONOGRAPHS: No ingredients listed in this section.
OSHA 29 CFR 1910: No ingredients listed in this section.
ENTRY ROUTES & EFFECTS OF OVEREXPOSURE:
Can cause severe burns to eyes, skin and mucous membranes.
Inhalation: Vapor can
cause severe irritation or burns to respiratory tract.
cause severe burns to the gastrointestinal system, which could result in death.
STATEMENT OF PRACTICAL TREATMENT:
Immediately flush exposed area thoroughly with water for at least
15 minutes while
removing contaminated clothing and shoes. Consult a physician. For eyes,
flush with large
amounts of cool water for at least 15 minutes. Get medical attention
to fresh air. If not breathing, begin artificial respiration. If breathing
is difficult, give
oxygen. Get medical attention immediately.
If swallowed, do not induce vomiting. Give several glasses of
water or milk. If vomiting
occurs spontaneously, keep airway clear. Get medical attention immediately.
- SECTION VII - SPECIAL PRECAUTIONS
- HANDLING AND STORAGE PRECAUTIONS:
Keep container tightly closed. Store in a cool, dry area protected
from corrosion, Store away from other
chemicals such as oxidizing agents, bases or metals.
STEPS TO BE TAKEN IF MATERIAL SPILLS OR LEAKS:
Evacuate area. Wear proper safety gear. For small spills, neutralize
with soda ash and, if permitted, flush to
sewer with large amounts of water. For larger spills, dike the liquid and
recover as much as possible into
polyethylene drums. Neutralize residue with soda ash and flush to sewer
with large amounts of water, if
permitted. Comply with applicable government regulations.
WASTE DISPOSAL METHOD:
Hydrochloric acid is an EPA hazardous waste due to corrosivity and must be
disposed of by an EPA approved
hazardous waste facility. Comply with all local, state and federal
- SECTION VII - SPECIAL PROTECTION INFORMATION
- RESPIRATORY PROTECTION:
Self-contained organic respirator should be available.
Use ventilation to maintain TLV below 5 ppm.
Full face shield, chemical goggles.
Acid suit, rubber boots, impervious gloves.
OTHER PROTECTIVE EQUIPMENT:
As needed to avoid all bodily contact and breathing of vapor.
