Guidance on Safe Use

First-aid measures

Description of first aid measures

General advice:

First Aid responders should pay attention to self-protection and use the recommended protective clothing (chemical resistant gloves, splash protection).  If potential for exposure exists refer to Section 8 for specific personal protective equipment. 

Inhalation: Move person to fresh air and keep comfortable for breathing.  If not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc).  If breathing is difficult, oxygen should be administered by qualified personnel.  Call a physician or transport to a medical facility. 

Skin contact : Remove material from skin immediately by washing with soap and plenty of water.  Remove contaminated clothing and shoes while washing.  Seek medical attention if irritation or rash occurs. Wash clothing before reuse.  Discard items which cannot be decontaminated, including leather articles such as shoes, belts and watchbands.  Suitable emergency safety shower facility should be available in work area. 

Eye contact: Wash immediately and continuously with flowing water for at least 30 minutes.  Remove contact lenses after the first 5 minutes and continue washing. Obtain prompt medical consultation, preferably from an ophthalmologist.  Suitable emergency eye wash facility should be immediately available.

Ingestion: If swallowed, seek medical attention.  Do not induce vomiting unless directed to do so by medical personnel.

 

Fire-fighting measures

Extinguishing media

Suitable extinguishing media: Alcohol-resistant foam.  Dry sand.  Dry chemical. 

Unsuitable extinguishing media: High volume water jet.  Do not use direct water stream.. 

Special hazards arising from the substance or mixture

Hazardous combustion products:

Silicon oxides.  Carbon oxides.  Nitrogen oxides (NOx).  Formaldehyde.  

Unusual Fire and Explosion Hazards:

Flash back possible over considerable distance..  Exposure to combustion products may be a hazard to health..  Flammable concentrations of vapor can accumulate at temperatures above flash point; see Section 9..  Flammable mixtures may exist within the vapor space of containers at room temperature..  Closed containers may rupture via pressure build-up when exposed to fire or extreme heat..  Vapours may form explosive mixtures with air.. 

Advice for firefighters

Fire Fighting Procedures:  Use water spray to cool unopened containers..  Evacuate area..  Collect contaminated fire extinguishing water separately. This must not be discharged into drains..  Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations..  Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed..  Do not use a solid water stream as it may scatter and spread fire.

Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.  Remove undamaged containers from fire area if it is safe to do so. 

Special protective equipment for firefighters: In the event of fire, wear self-contained breathing apparatus..  Use personal protective equipment.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Remove all sources of ignition.  Ventilate the area.  Use personal protective equipment.  Eliminate all sources of ignition in vicinity of spill or released vapor to avoid fire or explosion.  Ground and bond all containers and handling equipment.  Vapor explosion hazard. Keep out of sewers.  Follow safe handling advice and personal protective equipment recommendations

Environmental precautions:

Discharge into the environment must be avoided.  Prevent further leakage or spillage if safe to do so.  Prevent spreading over a wide area (e.g. by containment or oil barriers).  Retain and dispose of contaminated wash water.  Local authorities should be advised if significant spillages cannot be contained. 

Methods and materials for containment and cleaning up:

Non-sparking tools should be used.  Soak up with inert absorbent material.  Suppress (knock down) gases/vapours/mists with a water spray jet.  Clean up remaining materials from spill with suitable absorbant.  Local or national regulations may apply to releases and disposal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which regulations are applicable.  For large spills, provide dyking or other appropriate containment to keep material from spreading. If dyked material can be pumped, store recovered material in appropriate container. 

Handling and storage

Precautions for safe handling:

Do not get on skin or clothing.  Avoid inhalation of vapour or mist.  Do not swallow.  Do not get in eyes.  Keep container tightly closed.  Keep away from heat and sources of ignition.  Take precautionary measures against static discharges.  Take care to prevent spills, waste and minimize release to the environment.  Non-sparking tools should be used.  Handle in accordance with good industrial hygiene and safety practice.  CONTAINERS MAY BE HAZARDOUS WHEN EMPTY.  Since emptied containers retain product residue follow all (M)SDS and label warnings even after container is emptied.

Use with local exhaust ventilation.  Use only in an area equipped with explosion proof exhaust ventilation. 

Ensure all equipment is electrically grounded before beginning transfer operations.  This material can accumulate static charge due to its inherent physical properties and can therefore cause an electrical ignition source to vapors. In order to prevent a fire hazard, as bonding and grounding may be insufficient to remove static electricity, it isnecessary to provide an inert gas purge before beginning transfer operations.  Restrict flow velocity in order to reduce the accumulation of static electricity.  Ground and bond container and receiving equipment. 

Conditions for safe storage, including any incompatibilities:

Keep in properly labelled containers.  Store locked up.  Keep tightly closed.  Keep in a cool, well-ventilated place.  Store in accordance with the particular national regulations.  Keep away from heat and sources of ignition. 

Do not store with the following product types: 

Strong oxidizing agents.  Organic peroxides.  Flammable solids.  Pyrophoric liquids.  Pyrophoric solids.  Self-heating substances and mixtures.  Substances and mixtures, which in contact with water, emit flammable gases.  Explosives.  Gases. 

Unsuitable materials for containers: None known.

SpecialProvisions

Exposure controls / personal protection

Engineering controls: Use local exhaust ventilation, or other engineering controls to maintain airborne levels below exposure limit requirements or guidelines.  If there are no applicable exposure limit requirements or guidelines, general ventilation should be sufficient for most operations.  Local exhaust ventilation may be necessary for some operations. 

Individual protection measures

Eye/face protection: Use chemical goggles.  Chemical goggles should be consistent with EN 166 or equivalent. 

Skin protection

Hand protection: Use chemical resistant gloves classified under Standard EN374: Protective gloves against chemicals and micro-organisms.  Examples of preferred glove barrier materials include:  Butyl rubber.  Neoprene.  Nitrile/butadiene rubber ("nitrile" or "NBR").  Ethyl vinyl alcohol laminate ("EVAL").  Polyvinyl alcohol ("PVA").  Polyvinyl chloride ("PVC" or "vinyl").  Viton.  Examples of acceptable glove barrier materials include:  Natural rubber ("latex").  When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes according to EN 374) is recommended.  When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater  than 60 minutes according to EN 374) is recommended.  Glove thickness alone is not a good indicator of the level of protection a glove provides against a chemical substance as this level of protection is also highly dependent on the specific composition of the material that the glove is fabricated from. The thickness of the glove must, depending on model and type of material, generally be more than 0.35 mm to offer sufficient protection for prolonged and frequent contact with the substance. As an exception to this general rule it is known that multilayer laminate gloves may offer prolonged protection at thicknesses less than 0.35 mm. Other glove materials with a thickness of less than 0.35 mm may offer sufficient protection when only brief contact is expected.  NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all relevant workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), potential body reactions to glove materials, as well as the instructions/specifications provided by the glove supplier. 

Other protection: Use protective clothing chemically resistant to this material.  Selection of specific items such as face shield, boots, apron, or full body suit will depend on the task. 

Respiratory protection: Respiratory protection should be worn when there is a potential to exceed the exposure limit requirements or guidelines.  If there are no applicable exposure limit requirements or guidelines, use an approved respirator.  When respiratory protection is required, use an approved positive-pressure self-contained breathing apparatus or positive-pressure airline with auxiliary self-contained air supply.  For emergency conditions, use an approved positive-pressure self-contained breathing apparatus.
