---

Hydrochloric Acid 7647-01-0 10 – 36%

Water to make total of 100% (It may contain low levels of hydrofluoric acid)

Health Effects:

Acute:

Swallowed: Can kill if swallowed. May cause severe burns to the mouth, throat and stomach

Eye: Highly corrosive to eyes. Contamination of eyes can result in permanent injury. High concentration of vapours will cause irritation.

Skin: Contact with skin will result in severe irritation. Harmful in contact with the skin. Corrosive to skin, may cause skin burns.

Inhaled: the vapour is an irritant to the mucous membranes and respiratory tract. Possible harmful corrosive effects. An asphyxiant; exposure to high concentrations will cause suffocation.

Chronic: prolonged exposure may cause bronchitis, pneumonia and pulmonary oedema.

First Aid

If swallowed: Poison Information Centres in each state Capital City can provide additional assistance for scheduled poisons. Rinse mouth thoroughly with water immediately. Give water or milk to drink. DO NOT induce vomiting. Seek immediate medical assistance. Vomiting may cause further damage to the throat.

Eye: immediately irrigate with copious quantities of water for at least 15 minutes. Eyelids to be held open. Seek immediate medical assistance.

Skin: Wash effected areas with copious quantities of water immediately. If irritation occurs, seek medical advice. If swelling, blistering or irritation occurs seek medical advice. Remove contaminated clothing and wash before re-use. Treat skin and clothing with 1% sodium bicarbonate solution to neutralize acid residues

Inhaled: Remove victim from exposure – avoid becoming a casualty. Allow patient to assume most comfortable position and keep warm. Keep at rest until fully recovered. If breathing laboured and patient cyanotic (blue), ensure airways are clear and have qualified person give oxygen through a facemask. If breathing has stopped, apply artificial respiration at once. In the event of cardiac arrest, apply external cardiac massage. Seek medical attention.

Advice to doctor: Treat symptomatically as for strong acids.

Exposure Standards:

TLV/TWA: 7mg/m3, 5 ppm; Worksafe Australia. – peak limitation – Is the concentration that should not be exceeded even instantaneously.

Odour threshold: 1 – 5 ppm IDLH Value: 100 ppm

Engineering Controls:

Maintain concentration below recommended exposure limit. Use with adequate ventilation. Local exhaust ventilation usually required.

Keep containers in a well ventilated area.

Personal Protection:

The following personal protective equipment must be worn.

PVC, preoprene or nitrile rubber gloves. Safety glasses, goggles or faceshield as appropriate. Overalls or similar protective apparel. Wearing of the following personal protective equipment may be advisable. Splash apron, rubber boots. In confined spaces the following are recommended. Combination particulate/gas respirator, Class B, (inorganic vapour)

Flammability: Non flammable. Contact with strong alkalis may generate heat.

Environment: Avoid contaminating waterways. The product is strongly acidic and therefore may react with metals to produce hydrogen, a flammable gas.

Other precautions: Will react with water or steam to produce toxic and corrosive fumes. Keep away from strong oxodising agents and strong bases. Avoid contact with metals. Reacts with zinc, brass, galvinised iron, aluminium, copper and copper alloys. Keep away from cyanides and sulphides.

Storage

Storage: Store in a cool place and out of direct sunlight. Store in well-ventilated area. Store away from oxidising agents. Store away from foodstuffs. Keep containers securely sealed and protected against physical damage.

Not to be loaded with class 1, 4.3, 5.1, 5.2, 6*, 7, Foodstuff and foodstuff empties.

(* Where the class 6 substance is a cyanide and the class 8 substance is an acid). There may be instances with the technical grade products where there may be contamination due to hydrofluoric acid. Care should be taken especially where the material may be stored in glass vessels.

Spills & Disposal

Spills: Clear area of all unprotected personnel. Notify emergency services for large spills. Prevent contamination of drains and waterways. Use absorbent (soil, sand,

sawdust, inert material, vermiculite). Collect and seal in properly labeled drums for disposal. Nuetralise remaining product with lime or soda ash, adjusting pH to 6-10. Flush to sewer as a greatly diluted solution. Wear full protective clothing (see Personal Protection Section) self-contained breathing apparatus may be needed for prolonged periods of exposure. Refer to appropriate State Waste Disposal Authority. Observe local regulations. There may be instances with the technical grade products where there may be contamination due to hydrofluoric acid. Care should be taken especially where the material may be stored or used in glass vessels.

Fire/Explosion Hazard

Evacuate immediate area. Fire fighters to wear self contained breathing apparatus if risk of exposure to vapour or products of combustion. Decomposes on heating emitting toxic fumes.

Hazardous Decomposition Products: Hydrogen Chloride, Heating can cause expansion or decomposition leading to violent rupture of containers. Use water to keep the substance cool. Extinguish fire with water spray.
