Guidance on Safe Use

First-aid measures

General information:

In case of any health problems or doubts, get medical attention immediately. Maintain vital functions of a victim (artificial respiration, heart massage, oxygen supply) until the doctor arrival. If a victim is unconscious or their skin is bluish, put them in the recovery position. For first degree burns (sore redness) and second degree burns (sore blisters). cool under running waret for longer time. For third degree burns (redness, pale, chapped skin, usually not painful), bandage them with a sterile lint.

Inhalation :  Move exposed person to fresh air. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. Keep person warm and at rest. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.Ingestion: Wash out mouth with water. In the event of swallowing, induce patient to drink plenty of water.

Skin contact: Get medical attention immediately. Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Continue to rinse for at least 10 minutes. Chemical burns must be treated promptly by a physician. Wash clothing before reuse. Clean shoes thoroughly before reuse.

Eye contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open . Avoid big water stream due to the risk of mechanical damage of cornea.

Consumption: Do not induce vomiting. Do not admister neutralizing agents. Supply oxygen in case of dyspnoea. Give milk or white from hen egg for drinking.

Fire-fighting measures

Suitable extinguishing media :

LARGE FIRE: Use water spray, water fog or foam. DO NOT use direct water jet.

SMALL FIRE: Dry powder or carbon dioxide (CO2) extinguisher, dry sand or fire fighting foam.

Unsuitable Extinguishing Media :

(Do Not use) Direct water jet.

Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.

Combustion Products :

Carbon monoxide, carbon dioxide; sulphur dioxide and unburned hydrocarbons (smoke).

Specific hazards during fire fighting :

Vapour is denser than air – flashback may be possible over considerable distances.

Containers may explode under fire conditions - use water spray to cool unopened containers.

Do not allow run-off from fire fighting to enter drains or water courses – may cause explosion hazard in drains and may reignite on surface water.

Further information :

Special protective equipment for fire-fighters :

Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Accidental release measures

Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area).

Personal precautions :

Wear personal protective equipment.

Avoid breathing vapours or mist.

Ensure adequate ventilation and absence of sources of ignition.

Beware of accumulation of vapours in low areas or contained areas, where explosive concentrations may occur.

Environmental precautions :

Land spillage :

Prevent further leakage or spillage if safe to do so.

Prevent spillage from entering drains, sewer, basement or confined areas.

Spillages in water or at sea :

Prevent further leakage or spillage if safe to do so.

If the spillage contaminates rivers, lakes or drains inform respective authorities.

Methods for clean up :

Contain spillage.

Small spillages can be taken up by collection with non-combustible absorbent material, (e.g. sand, earth,

diatomaceous earth, vermiculite,  and placed in container for disposal according to local / national

regulations. it can be also neutralizes with calcium compounds (quicklime, hydrated lime, calcium carbonate) or if there are not any, with other mild alkali agents (e.g. the solution of sodium carbonate).

Water spillage:

If the Flash Point exceeds the Ambient Temperature by 10 deg C or more, use containment booms and remove from the surface by skimming or with suitable absorbents when conditions permit.  If the Flash Point does not exceed the Ambient Air Temperature by at least 10 deg C, use booms as a barrier to protect shorelines and allow material to evaporate.  Seek the advice of a specialist before using dispersants.

Further accidental release measures :

Spillages of liquid product will create a fire hazard and form an explosive atmosphere.

Ensure all equipment is non sparking or electrically bonded.

Avoid direct contact with released material.

Stay upwind.

Keep non-involved personnel away from the area of spillage.

Ensure adequate ventilation, especially in confined areas.

Handling and storage

Advice on safe handling :

Smoking, eating and drinking should be prohibited.

Use only in well ventilated areas.

Avoid all sources of ignition.

Use proper bonding and/or grounding procedures.

This material is a static accumulator: Take precautionary measures against static discharges.

Avoid contact with heat and ignition sources and oxidizing agents.

Containers should be opened only under exhaust ventilation hood.

Do not allow splash filling of bulk volumes.

Do not use compressed air for filling, discharging or handling.

Do not pressurise, cut, weld, braze, solder, drill, or grind on containers.

Dispose of rinse water in accordance with local and national regulations.

The vapour is heavier than air, beware of accumulation in pits and confined spaces.

The product will float on water and can be reignited on surface water.

Handle empty containers with care; vapour residue may be flammable.

Ensure that all relevant regulations regarding explosive atmospheres, and handling and storage

facilities of flammable products are followed.

Cleaning, inspection and maintenance of the internal structure of storage tanks must be done

only by properly equipped and qualified personnel as defined by national, local or company

regulations.

Storage :

No smoking.

Store in either mild steel or stainless steel containers or vessels.

Store in a designated cool and well-ventilated place.

Store in the original, tightly closed, container.

Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Keep container tightly closed and properly labelled.

Vapour space above stored liquid may be flammable/explosive unless blanketed with inert gas.

Storage installations should be designed with adequate bunds so as to prevent ground and water pollution in case of leaks or spills.

Fixed storage containers, transfer containers and associated equipment should be earthed and bonded to prevent accumulation of static charge.
