EC number: 201-201-8
CAS number: 79-38-9
Description of necessary first-aid measures
- If breathed in, move person into fresh air.
- Victim to lie down in the recovery position, cover and keep him warm.
- Oxygen or artificial respiration if needed.
- Immediate medical attention is required.
In case of eye contact:
- Keep eyelids open to allow evaporation of product.
- Flush eyes with running water for several minutes, while keeping the eyelids wide open.
In case of skin contact:
- Allow to evaporate.
- Rinse with lukewarm running water.
- Remove clothes carefully
- Wash off with warm water and soap.
- Call a physician immediately.
- not applicable
Suitable extinguishing media:
- Dry chemical
- Carbon dioxide (CO2)
Unsuitable extinguishing media:
Specific hazards arising from the chemical:
- Extremely flammable
- Flash back possible over considerable distance.
- Vapours may form explosive mixtures with air.
- Vapours are heavier than air and may spread along floors.
- Risk of ignition.
- Explosion risk in case of fire.
- Thermal decomposition can lead to release of toxic and corrosive gases.
Special protective actions for fire-fighters:
- Wear self-contained breathing apparatus and protective suit.
- When intervention in close proximity wear acid resistant over suit.
- Evacuate personnel to safe areas.
- Approach from upwind.
- Protect intervention team with a water spray as they approach the fire.
- Keep containers and surroundings cool with water spray.
- Keep product and empty container away from heat and sources of ignition.
Most important symptoms/effects, acute and delayed
- Symptoms: Dizziness, narcosis, Breathing difficulties
- Symptoms: Frostbite, Burn
- Symptoms: Frostbite
Personal precautions, protective equipment and emergency procedures
Advice for non-emergency personnel:
- Prevent further leakage or spillage if safe to do so.
Advice for emergency responders:
- The product evaporates readily.
- Ventilate the area.
- Suppress (knock down) gases/vapours/mists with a water spray jet.
- Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.
- Cover the spreading liquid with foam in order to slow down the evaporation.
- Keep away from open flames, hot surfaces and sources of ignition.
- Refer to protective measures listed in sections 7 and 8.
- Should not be released into the environment.
- Do not flush into surface water or sanitary sewer system.
Methods and materials for containment and cleaning up:
- Soak up with inert absorbent material.
- Suitable material for picking up
- Dry sand
- Shovel into suitable container for disposal.
Precautions for safe handling:
- Use only in well-ventilated areas.
- Keep away from heat and sources of ignition.
- To avoid thermal decomposition, do not overheat.
- Avoid skin contact with leaking liquid (danger of frostbite).
- Purge piping circuits and equipment with nitrogen.
- No sparking tools should be used.
- Use only explosion-proof equipment.
- Take measures to prevent the build up of electrostatic charge.
Conditions for storage, including incompatibilities
- Keep in a well-ventilated place.
- Keep cool. Protect from sunlight.
- Keep away from combustible material.
- Keep away from Incompatible products.
- Keep only in the original container at a temperature not exceeding 50 °C.
- Provide electrical equipment safe for hazardous locations.
- Ensure all equipment is electrically grounded before beginning transfer operations.
- Do not confine the product in a circuit, between closed valves, or in a container without a vent.
- Stainless steel
- Carbon steel
- Warning! Container under pressure.
- For further information, please contact: Supplier
Appropriate engineering controls:
- Ensure adequate ventilation.
- Apply technical measures to comply with the occupational exposure limits.
Individual protection measures
- Use respirator when performing operations involving potential exposure to vapour of the product.
- The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used.
- Remove respiratory and skin/eye protection only after vapours have been cleared from the area.
- Use only respiratory protection that conforms to international/ national standards.
- Handle in accordance with good industrial hygiene and safety practice.
- Neoprene gloves
- Take note of the information given by the producer concerning permeability and break through times, and of special workplace conditions (mechanical strain, duration of contact).
- Tightly fitting safety goggles
- Chemical resistant goggles must be worn.
- If splashes are likely to occur, wear:
Skin and body protection:
- Chemical resistant apron
- Ensure that eyewash stations and safety showers are close to the workstation location.
- Gloves, overalls and boots have to be double layered (protection against cold temperature).
- Take off contaminated clothing and shoes immediately.
- Wash contaminated clothing before re-use.
- When using do not eat, drink or smoke.
- Wash hands before breaks and at the end of workday.
Environmental exposure controls:
- Dispose of rinse water in accordance with local and national regulations.
- Stable under recommended storage conditions.
Possibility of hazardous reactions:
- Keep away from oxidizing agents.
- Potential for exothermic hazard
Conditions to avoid:
- Exposure to moisture.
- Heat, flames and sparks.
Materials to avoid:
- Flammable materials, Combustible material
- Oxidizing agents, Oxygen, Halogenated compounds, Water
Hazardous decomposition products:
- Gaseous hydrogen fluoride (HF)., Gaseous hydrogen chloride (HCl).
Waste disposal methods:
- Can be incinerated, when in compliance with local regulations.
- The incinerator must be equipped with a system for the neutralisation or recovery of HF.
- In accordance with local and national regulations.
- Purge the container with nitrogen and direct the gas to a treatment plant.
- Empty containers can be landfilled, when in accordance with the local regulations.
