First-aid measures

Symptoms and effects.

Gas/mists are irritating to the respiratory system. May cause delayed pulmonary oedema.

The product is corrosive to eyes,skin and upper respiratory tract.


IF exposed or if you feel unwell: call a POISON CENTER or doctor/physician.


Remove casualty to fresh air and keep at rest in a position comfortable for breathing.

If symptoms persist or breathing gets difficult, consult a physician.


Remove/Take off immediately all contaminated clothing including shoes. Rinse skin with water or shower. In case of reddened skin or burns seek medical advice.


Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Eyelids should be held away from the eyeball to ensure thorough rinsing. Always consult an eye doctor!


Only when casualty is conscious, rinse mouth with plenty of water. Give water to drink. Do NOT induce vomiting.  Take casualty immediately to hospital!

Advice to physician

Symptomatic treatment is advised.

Fire-fighting measures

Extinguishing media

Not applicable . Product itself is not flammable.

Unsuitable extinguishing media

Not applicable.

Hazardous decomposition / combustion products

Hydrogen chloride (gas).

Protective equipment

Wear self-contained breathing appartatus and acid-proof protective suits.

Fire and explosion hazard

Product itself is not flammable or explosive. The product reacts with metals with evolution of highly flammable hydrogen.

Accidental release measures

Evacuate personnel to safe areas (keep upwind).

Call the emergency brigade.

Use personal protective equipment (see exposure controls/ personal protection)

Surpress gas/mists with water spray jet.

Personal precautions

Wear suited personal protective equipment (see Expsoure controls/ personal protection).

Environmental precautions

Avoid release to the environment.

Collect leaking product in suited acid-proof containers. Stop the leakage by shutting valves, if this can be done safely.

Do not allow to enter into drain or surface waters. Retain leaking product with earth, diatomeous earth (kieselguhr) or universal absorbant. Collect contaminated material in acid-proof containers. Dispose of contaminated material and its container as hazardous waste according to local regulations.

In case of entry into waterways, drains or soil inform the responsible authorities

Methods for cleaning up

Neutralise small spillages with lime or soda ash. Rinse remnant with plenty of water into drains.

Clean contimated tools with plenty of water.

Handling and storage


The usual precautions for handling of chemicals should be observed. Avoid any direct contact with the product.

Fire and explosion prevention

None. Substance is not flammable.

Storage requirements

Store only in double-walled leakage monitored tanks, or in tanks/containers in a bunded area. Provide impermeable flooring and corrosion resistant equipment.

Keep containers tightly closed in a dry and well-ventilated place. Provide sufficient air exchange and/or exhaust in work rooms.

Store in steel tanks lined with hard rubber or other resitant coating or inliner, or in plastic containers made of PE, PP, chloro or fluoro polymers, or in glass bottles.

To be avoided: unprotected metals, glass-fibre reinforced plastic (GRP).

Do not store together with incompatible materials (see Stability and reactivity)

Safe handling advice:

See exposure scenarios for expsoure controls.

Use product wherever possible in closed system.

Install eyewash station and emergency showers nearby to workstations.

Exposure controls / personal protection

see exposure scenarios for exposure controls.

Personal protective equipment

Respiratory protection:

- Low concentrations and short term activity (max 15 min): filter masks with filter type E. Be aware of the filter capacity and the use-time limitation!

- High concentrations or unknown exposure or prolonged activity: self-contained breathing apparatus.

Hand protection:

Protective gloves have to conform to EN 374.

Suited glove material: fluoro rubber, butyl rubber, chloroprene, nitrile rubber, PVC, latex.

The suitability of a specific glove of a supplier has to be determined depending on the use conditions (chemical, mechanical, thermal stress, and use/contact time)

Eye and face protection:

Safety glasses with side protection shield or goggles conform to EN 166.

Full face mask.

Skin and body protection:

Acid-proof protective overall, safety shoes or boots.

General protective and hygiene measures:

Avoid contact with skin and eyes.

Do not inhale gas or aerosol (mist).

Apply PPE as required.

Remove contaminated clothing immediately.

Wash hands immediately after handling chemicals and before breaks.

Do not eat, drink and smoke at work, keep away foodstuffs and beverages.

Stability and reactivity


Product is stable under recommended storage and use conditions.


The product reacts with:

- common construction metals with evolution of highly flammable hydrogen gas,

- alkali and organic bases with violent evolution of heat,

- lime stone, marble, dolomite and other carbonic minerals with evolution of suffocating CO2 gas,

- strong oxidants (bleaching agents, conc. H2O2, HNO3, etc. and their salts, chromates, permanganates, etc) with evolution of toxic chlorine gas,

- sulphides with evolution of toxic H2S gas,

- sulphites, hydrogen sulphites and pyro sulphites with evolution of toxic SO2 gas,

- with sodium azide to highly toxic and explosive hydrazoic acid,

- any other chemical, that is prone to (dangerous) reaction/decomposition with acids.

Hazardous decomposition products

By heating evolution of corrosive and toxic hydrogen chloride gas.  .
