Guidance on Safe Use

First-aid measures

Description of first aid measures

Immediately remove contaminated clothing. If danger of loss of consciousness, place patient in

recovery position and transport accordingly. Apply artificial respiration if necessary. First aid personnel

should pay attention to their own safety.

If inhaled:

Keep patient calm, remove to fresh air, seek medical attention. Immediately inhale corticosteroid dose

aerosol.

On skin contact:

Immediately wash thoroughly with soap and water, seek medical attention.

On contact with eyes:

Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,

consult an eye specialist.

On ingestion:

Rinse mouth immediately and then drink plenty of water, seek medical attention.

Most important symptoms and effects, both acute and delayed

Symptoms: The most important known symptoms and effects are described in the labelling (see

section 2) and/or in section 11.

Indication of any immediate medical attention and special treatment needed

Treatment: Treat according to symptoms (decontamination, vital functions), no known specific

antidote. Pulmonary odema prophylaxis. Medical monitoring for at least 24 hours.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

dry powder, carbon dioxide, foam

Unsuitable extinguishing media for safety reasons:

water

Special hazards arising from the substance or mixture

hydrogen chloride, carbon oxides, nitrogen oxides

The substances/groups of substances mentioned can be released in case of fire.

Advice for fire-fighters

Special protective equipment:

Wear self-contained breathing apparatus and chemical-protective clothing.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Breathing protection required. Avoid contact with the skin, eyes and clothing.

Environmental precautions

Do not empty into drains.

Methods and material for containment and cleaning up

For small amounts: Pick up with suitable absorbent material (e.g. sand, sawdust, general-purpose

binder, kieselguhr).

For large amounts: Pump off product.

Cleaning operations should be carried out only while wearing breathing apparatus. Clean

contaminated floors and objects thoroughly with water and detergents, observing environmental

regulations. Collect waste in suitable containers, which can be labeled and sealed. Incinerate or take

to a special waste disposal site in accordance with local authority regulations.

Handling and storage

Precautions for safe handling

Ensure thorough ventilation of stores and work areas. Protect against moisture.

Protection against fire and explosion:

Vapours may form ignitable mixture with air. Prevent electrostatic charge - sources of ignition should

be kept well clear - fire extinguishers should be kept handy.

Conditions for safe storage, including any incompatibilities

Further information on storage conditions: Avoid extreme heat. Keep container tightly closed and dry;

store in a cool place. Keep away from sources of ignition - No smoking.

Storage stability:

Storage duration: 3 Months

Protect against moisture.

From the data on storage duration in this safety data sheet no agreed statement regarding the

warrantee of application properties can be deduced.

Exposure controls / personal protection

Personal protective equipment

Respiratory protection:

Self-contained breathing apparatus.

Hand protection:

Chemical resistant protective gloves (EN 374)

Suitable materials also with prolonged, direct contact (Recommended: Protective index 6,

corresponding > 480 minutes of permeation time according to EN 374):

butyl rubber (butyl) - 0.7 mm coating thickness

fluoroelastomer (FKM) - 0.7 mm coating thickness

Manufacturer's directions for use should be observed because of great diversity of types.

Supplementary note: The specifications are based on tests, literature data and information of glove

manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g.

temperature) it must be considered, that the practical usage of a chemical-protective glove in practice

may be much shorter than the permeation time determined through testing.

Eye protection:

Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.

Body protection:

Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting

boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of

dust).

General safety and hygiene measures

Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray.

water/air:

Reaction with: water

Flammable gases: no

Toxic gases: yes

Which toxic gases: hydrogen chloride (HCl)

Corrosive gases: yes

Which corrosive gases: hydrogen chloride (HCl)

Smoke or fog: yes

Type of smoke or fog: Hydrochloric acid

Peroxides:

Which Peroxides:

Formation of

flammable gases:

Remarks: Forms no flammable gases in the

presence of water.

Chemical stability

The product is stable if stored and handled as prescribed/indicated.

Possibility of hazardous reactions

Evolution of corrosive gases/vapours. Reacts with water and basic components to generate heat. On

contact with water, gaseous decomposition products are formed, which cause build-up of pressure in

tightly closed containers. Reacts with alkalies and metals. Reacts with alcohols, amines, aqueous

acids and alkalies. Reacts with water and moisture, with formation of hydrogen chloride. Partly very

violent reactions with bases and numerous organic classes of substances such as alcohols and

amines. Addition of water leads to increase in temperature. In damp air hydrochloric acid formation is

possible. Violent reactions with water and/or alcohols, with formation of hydrochloric acid.

Substance/product is highly reactive. Violent and explosive reaction with water. Vapours may form

ignitable mixture with air.

Conditions to avoid

Avoid direct sunlight. Avoid electro-static charge. Avoid humidity. Avoid heat. Avoid prolonged storage.

Disregard of the conditions mentioned may result in undesirable decomposition reactions.

Incompatible materials

Substances to avoid:

alcohols, bases, amines, alkaline reactive substances, water

Hazardous decomposition products

Hazardous decomposition products:

hydrogen chloride

Disposal considerations

Waste treatment methods

Incinerate in suitable incineration plant, observing local authority regulations.

A waste code in accordance with the European waste catalog (EWC) cannot be specified, due to

dependence on the usage.

The waste code in accordance with the European waste catalog (EWC) must be specified in

cooperation with disposal agency/manufacturer/authorities.

Contaminated packaging:

Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling

after being thoroughly cleaned.
