3. Hazard Identification
Emergency Overview:
Extremely corrosive. The severity of damage depends on the concentration of the acid and the duration
of the exposure. In general, solutions and mists with a pH of 3 or less are a significant health concern.
Contact with water will generate considerable heat. Contact with most metals will generate flammable
hydrogen gas.
Routes of Entry:
Inhalation, Skin Contact, Eye contact, Ingestion
Symptoms of Exposure:
Inhalation:
HCl is a very strong acid. Solutions can be extremely corrosive. The severity of effects depends on the
concentration of the solution and the duration of contact. In general, HCl solutions and mist with a pH of 3
or less are a significant health concern.
Vapour or mist from concentrated solutions can cause severe nasal irritation, sore throat, choking,
coughing and difficulty breathing 50100 ppm.2 Prolonged exposures can cause burns and ulcers to
the nose and throat.
Severe exposures e.g., 10002000 ppm, for even a few minutes, can cause a lifethreatening
accumulation of fluid in the lungs pulmonary edema.2 Symptoms of pulmonary edema such as
shortness of breath can be delayed for several hours after the exposure.
Skin Contact:
Hydrochloric acid liquid can cause severe irritation redness, swelling, and pain and corrosive skin
damage with permanent scarring or even death.
High vapour or mist concentration may cause redness, irritation and burns to skin if contact is prolonged.
Skin covered by perspirationdampened clothing can also be affected.
Eye Contact:
Low concentrations of vapour or mist 1035 ppm can be immediately irritating, causing redness.2
Concentrated vapour, mist or splashed liquid can cause severe irritation, burns and permanent blindness.
Ingestion:
HCl solutions can cause corrosive burns to mouth, throat, esophagus and stomach. Symptoms may
include difficulty in swallowing, intense thirst, nausea, vomiting, diarrhea and in severe cases, collapse
and death.
Small amounts of acid which enter the lungs during ingestion or vomiting aspiration can cause serious
lung injury and death.

4. First Aid Measures
Skin:
As quickly as possible, flush contaminated area with lukewarm, gently running water for at least 20
minutes. Under running water, remove contaminated clothing, shoes and leather goods. Obtain medical
attention immediately.
Eyes:
Immediately flush the contaminated eyes with lukewarm, gently flowing water for at least 20 minutes,
holding the eyelids open. Take care not to rinse contaminated water into the nonaffected eye. Obtain
medical attention immediately.
Inhalation:
Remove source of contamination or move victim to fresh air. If victim is unconscious, do not give
anything by mouth. Check breathing and pulse. If breathing has stopped, trained personnel should give
artificial respiration. If heart has stopped, give cardiopulmonary resuscitation CPR immediately. If
breathing becomes rapid and bubbly, place the the person in a sitting position, and give oxygen if
possible. Obtain medical attention immediately.
Ingestion:
Never give anything by mouth to an unconscious or convulsing person. Otherwise, rinse residual
hydrochloric acid from the mouth with water. If the victim can swallow, give one cup of water or milk to
dilute the material in the stomach. Do not induce vomiting. If vomiting occurs naturally, rinse mouth and
give water again. Obtain medical attention immediately.
5. FireFighting Measures
Conditions Of Flammability:
Not flammable
Means To Extinguish:
Does not burn. Use extinguishing agents compatible with acid and appropriate for the burning material.
Use water spray to keep fireexposed containers cool.
Hazardous Combustion Products:
Hydrogen and chlorine gas may form at temperatures greater than 1,500癈.
Flash Point & Method: Not combustible does not burn
Upper Flammability Limit: Not applicable
Lower Flammability Limit: Not applicable
AutoIgnition Temperature: Not applicable
Mechanical Impact Sensitivity: Not available
Static Discharge Sensitivity: Not sensitive

6. Accidental Release Measures
Leak Or Spill Procedures:
Only persons wearing protective equipment should be allowed in areas of leaks. Ventilate area. Vapors
evolved from spill or leak can be knocked down with water fog or spray. Small spills and residues can be
neutralized with alkalies such as soda ash or lime. This will release carbon dioxide, so use caution.
Large spills should be contained, and if not recoverable, then diluted with water or flushed to holding area
and neutralized.
Waste Control Procedures:
Consult appropriate Federal, State/Provincial and local regulatory authorities to ascertain disposal
procedures. Waste hydrochloric acid or acid contaminated water, must never be discharged directly into
sewers or surface water. Contaminated materials should be neurtralized with soda ash Na2CO3, lime
CaO, or limestone CaCO3. The residual sludge can be shoveled into containers for disposal.
7. Handling Storage
Handling Procedures And Equipment:
When diluting or preparing solutions, slowly add acid to water to avoid boiling and splattering. Always use
in a well ventilated area, preferably with local ventilation.
Storage:
Store closed containers in a clean, cool, open or well ventilated area. Keep out of sun. Keep away from
incompatible materials.
8. Exposures Controls / Personal Protection
Protective Equipment:
<50ppm Supplied air respirator, selfcontained breathing apparatus, chemical cartridge respirator, or a
powered air purifying respirator both with cartridges to protect against hydrogen chloride.
>100ppm supplied air respirator operated in a continuous flow mode, fullfacepiece supplied air
respirator, or fullfacepiece selfcontained breathing apparatus.
Nonventilated chemical safety goggles or a full face shield.
Impervious gloves, body suits, boots and/or other protective clothing. Recommended materials for
TM TM TM
protective clothing: butyl rubber, neoprene, nitrile rubber, Teflon , Responder , Viton . Have a safety
shower and eyewash fountain readily available in the immediate work area.
Engineering Controls:
Handling should be done in closed ventilation system e.g. exhaust hood. In areas of heavy handling
mechanical ventilation should be provided sufficient to reduce the vapour mist concentration below the
permissible levels. Open processing equipment may require local exhaust systems. All must be
corrosion resistant. Provide eye wash and quick drench facilities in areas of use.

11. Toxicological Information
Skin Contact: Can cause severe irritation redness, swelling, and pain and corrosive
skin damage with permanent scarring or even death. Prolonged
exposure to vapour mists of high concentration will cause redness and
burns to skin.
Skin Absorption: Usually penetrates the full thickness of the skin. Less exposure may
cause dermatitis and photo sensitization.
Eye Contact: Low concentration of vapour or mist can be irritating, causing redness.
Concentrated vapour, mist or splashed liquid can cause severe
irritation, burns and permanent blindness.
Inhalation: Vapour or mist can cause irritation of the nose, throat and upper
respiratory tract. Symptoms include coughing, choking, and bleeding
of the nose and gums. Severe exposure can result in pulmonary
edema and corrosion of tissues in the nose and throat.
