Guidance on Safe Use

First-aid measures

4.1. Description of first aid measures

General instructions

IF THE SUBSTANCE IS INHALED, IS CAUSTIC TO THE SKIN, OR GETS INTO THE EYES, YOU MUST SEEK MEDICAL TREATMENT IMMEDIATELY.

If health problems occur or if you suspect that your health may have been affected, contact your physician and give the information stated on this safety data sheet. It is necessary to keep the vital functions going until a physician arrives (i.e. check heartbeat, ensure artificial respiration, heart massage). If the affected person has lost consciousness or if you believe that he/she may lose consciousness, transport the person to a healthcare provider in a stabilised position, lying on his/her side. In the case of first degree burns (painful red spots) and second degree burns (painful blisters), cool the affected locations with a stream of cold water. In the case of third degree burns (black spots, crumbling pale skin, usually painless), do not cool the affected place, but cover it with a clean piece of cloth. The affected person must not lose body heat.

SPECIAL MEANS REQUIRED AT THE WORKPLACE: Eye bath and safety shower.

When inhaled

Take the afflicted person into the open air, rinse his/her mouth and nose with water, keep him/her warm and quiet. Call for professional medical help.

In case of contact with skin

Rinse the affected places with water immediately and remove contaminated clothing and shoes (cut the person's hair and nails, if necessary). Wash the skin well, but try to avoid irritating the skin mechanically, with a large quantity of lukewarm water. Do not use soap or neutralising agents and avoid mechanical irritation. Keep rinsing the affected person until the physician arrives (keep rinsing for 20 minutes at least). Affected places

should be covered with a sterile bandage (or a clean piece of cloth). Call for professional medical help.

In case of contact with eyes

Rinse the eyes with a large quantity of clean, lukewarm water immediately. Keep washing even if it is necessary to exert some force to open the afflicted person’s eyelids. Wash the eye from the inside corner to the outside and do not stop until the physician arrives. If the afflicted person is wearing contact lenses, they must be removed immediately. Call for a professional medical help.

When swallowed

First rinse the mouth and then make the affected person drink 1-2 dl of water with charcoal, one sip at a time. Number of charcoal: 1 – 10 multiple of a swallowed corrosive substance. Do not make the person vomit!

It is essential to seek medical treatment rapidly.

4.2. Most important symptoms and effects, both acute and delayed

When inhaled – Burning pain, pain and caustic effect on the mucous membranes of the respiratory tracts persistent irritating cough, breathlessness.

In case of contact with skin – Burning pain, pain, caustic effects

In case of contact with eyes – Burning pain, pain, caustic effects

When swallowed – Burning pain, pain, caustic effects, neurotoxicity, convulsion, liver and kidney damage, arrhythmia, exitus

4.3. Indication of any immediate medical attention and special treatment needed

Information for physician

- in case of contact with eyes: it is possible to apply a local anaesthetic (tetracaine) before rinsing

- when inhaled – prophylactic inhalation of corticosteroides (beclomethason - Aldecin, Becotide e.g.)

and physiological solution with 5% Panthenol.

- in case of contact with skin: inactivation with glycerol, edible oil or polyethyleneglycol 300-400.

Fire-fighting measures

5.1. Extinguishing media

Suitable extinguishing media

Powder or snow fire extinguisher. In the case of a large-scale fire, use heavy foam with a polar foam maker, or a split water stream. Containers should be cooled with a screen of water. You should try to get them out of the fire.

Unsuitable extinguishing media:

Direct water jet.

5.2. Special hazards arising from the substance or mixture

While the substance burns, it produces toxic products. As the substance is very volatile, it may produce highly corrosive vapours. Mixtures of the steam of the substance with the air are explosive.

5.3. Advice for firefighters

When fighting the fire in the dangerous zone, you must use an isolation breathing apparatus as well as a protective anti-chemical pressure suit.

Further data:

Flammability Class: III (ČSN 65 0201)

Temperature class: T1 (ČSN 33 0371)

Explosive group: IIA (ČSN 33 0371)

Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

Personal precautions

Close the place of the accident. Send away all persons not involved in rescue works. When managing the emergency, use an isolation breathing apparatus and full anti-chemical suit. If this is not possible, use the personal emergency equipment described in Section 8. Remove or switch off all sources of ignition. Leaking tankers should be driven to safe locations, while it is necessary to prevent the liquid from leaking by closing or sealing the place of the leakage. It is also necessary to measure the concentration of substance in the area continuously (see point 5.3)

6.2. Environmental precautions

Prevent the substance from leaking into the sewerage system, ground and surface water, or into the soil. If the substance leaks into a watercourse, inform the water consumers immediately. If the capacity of the leakage source is large, raise emergency alarm immediately.

6.3. Methods and material for containment and cleaning up

The leaked liquid should be enclosed and pumped into a container suitable for further processing or disposal. The remnants should be absorbed into a suitable porous material (sand, vapex, infusorial earth). When storing and handling the substance, make sure the area is ventilated thoroughly. Disposal of the substance is governed by the valid waste handling legislation, see also Section 13.

Handling and storage

7.1. Precautions for safe handling

In compliance with the standards ČSN 65 0201; provide good vapour ventilation and, for the work place, exhaust, prevent the escape of substance vapours into the atmosphere, use working protective means and keep safety measures in compliance with Point No. 8, handle in a manner as to prevent spillage or escape, prevent contact of the substance with open flame, sparks or hot surfaces.

7.2. Conditions for safe storage, including any incompatibilities

In compliance with the standards ČSN 65 0201; keep ventilating the storage room efficiently, use protective means in compliance with Point No. 8, store in closed packaging or tanks only, do not store together with food or strong oxidising agents, keep reservoirs, tanks and receptacles dry and tightly closed.

7.3. Specific end use(s)

Not determined.
