Guidance on Safe Use

First-aid measures

Description of first aid measures

General information:

Remove contaminated clothes at once. In case of accident or if you feel unwell seek medical advice immediately (show the label if

possible). Observe self-protection for first aid. Take persons to a safe place. Keep warm, in restful position, cover up.

After contact with the eyes:

Rinse immediately with plenty of water for 10-15 minutes and seek medical advice. Keep eyelids well open to rinse the whole eye

surface and eyelids with water. Continue to bathe eyes during transport to medical practitioner.

After contact with the skin:

Wash immediately with plenty of water. Remove contaminated clothes at once. In serious cases, use emergency shower

immediately. Seek medical advice and clearly identify substance. Do not use ointments or plasters unless recommended by

medical practitioner. Do not take clothing home for washing.

After inhalation:

Move to fresh air, keep the victim laying down and restful. If breathing has stopped, give artificial respiration. Administer oxygen in

case of breathing difficulties. Seek medical advice and clearly identify substance.

After swallowing:

Rinse mouth with water. If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice

immediately and produce the label or packaging. Never give an unconscious person anything by mouth!

Most important symptoms and effects, both acute and delayed

Any relevant information can be found in other parts of this section.

Indication of any immediate medical attention and special treatment needed

Symptomatic treatment. Further toxicology information must be observed.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

alcohol-resistant foam , carbon dioxide , dry sand . Application of foam will release at least initially significant amounts of

flammable and corrosive vapors. These vapors could be trapped under the foam blanket.

Extinguishing media which must not be used for safety reasons:

water , extinguishing powder , halones .

Special hazards arising from the substance or mixture

Hazardous combustion products: hydrogen chloride .

Advice for firefighters

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air. Use tightly fitting chemical protection suit.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protection equipment. Task force: Use tightly fitting chemical protection suit. Keep

unprotected persons away. Avoid contact with eyes and skin. Avoid inhaling mists and vapours. Do not walk through spilled

material. Ensure adequate ventilation.

Environmental precautions

Prevent material from entering surface waters, drains or sewers and soil. Condense gasses/vapours/mists using a directed spray

of water. Retain contaminated water/extinguishing water. Dispose of in prescribed marked containers.

Methods and material for containment and cleaning up

Do not flush away with water. Take up mechanically and dispose of according to local/state/federal regulations. Exhaust vapours.

Clean up with plenty of water.

Further information:

Eliminate all sources of ignition.

Reference to other sections

Relevant information in other sections has to be considered. This applies in particular for information given on personal protective

equipment and on disposal.

Handling and storage

Precautions for safe handling

Precautions for safe handling:

Ensure adequate ventilation. Must be syphoned off in situ. Keep away from incompatible substances.

Precautions against fire and explosion:

Flammable vapors may accumulate and form explosive mixtures with air in containers, process vessels, including partial, empty

and uncleaned containers and vessels, or other enclosed spaces. Vapours heavier than air, therefore inflammable gas mixture

may form mainly near floor. Keep away from sources of ignition and do not smoke. Take precautionary measures against

electrostatic charging. Cool endangered containers with water.

Conditions for safe storage, including any incompatibilities

Conditions for storage rooms and vessels:

none known .

Advice for storage of incompatible materials:

not applicable .

Further information for storage:

Protect against moisture. Store in original container only. Keep container tightly closed and store in a cool, well ventilated place.

CAS No.       Material              Type       mg/m3       ppm

7647-01-0       Hydrogen chloride       AGW       3,0       2,0

7647-01-0       Hydrogen chloride       EU       8,0       5,0

Hydrogen chloride (CAS-Nr. 7647-01-0): Refer to Technical Rules for Hazardous Substances "TRGS 900" for more details on the

German AGW.

Hydrogen chloride (CAS no. 7647-01-1): the short-time exposure value of the EU threshold is 15 mg/m3 (= 10 ppm).

Exposure controls

Exposure in the work place limited and controlled

General protection and hygiene measures:

Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke when handling. Wash hands at the end of

work and before eating.

Personal protection equipment:

Respiratory protection

Respirator must be worn if exposed to dust. Suitable respiratory equipment: Respirator with a full face mask, according to

acknowledged standards such as EN 136.

Recommended Filter type: Combined filter type ABEK-P2 (certain inorganic, organic and acidic gases and vapors;

ammonia/amines; particles), according to acknowledged standards such as EN 14387

If inhalative exposure above the occupational exposure limit cannot be excluded, adequate respiratory protection equipment must

be used. Suitable respiratory equipment: Respirator with a full face mask, according to acknowledged standards such as EN 136.

Recommended Filter type: Combined filter type ABEK-P2 (certain inorganic, organic and acidic gases and vapors;

ammonia/amines; particles), according to acknowledged standards such as EN 14387

For long or intense exposure, use respiratory protective equipment. Suitable respiratory equipment: Positive pressure self

contained breathing apparatus, according to acknowledged standards such as EN 137.

Observe the equipment manufacturer's information and wear time limits for respirators.

Eye protection
