Guidance on Safe Use

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 the specific personal protective equipment recommended.  

INHALATION

Move person to fresh air. If person is not breathing, call an emergency responder or ambulance, then give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask etc.). Call a poison control centre or doctor for treatment advice.  

SKIN CONTACT

Take off contaminated clothing. Rinse skin immediately with plenty of water for 15 - 20 minutes. Call a poison control centre or doctor for treatment advice.  

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

No emergency medical treatment necessary.  

INDICATION OF IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED

Chemical eye burns may require extended irrigation.  Obtain prompt consultation, preferably from an ophthalmologist.  No specific antidote.  Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.  Have the Safety Data Sheet, and if available, the product container or label to hand when calling a poison control centre or doctor, or going for treatment.  

MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED

Aside from the information provided above, no additional symptoms and effects are anticipated.

Fire-fighting measures

EXTINGUISHING MEDIA

- Suitable extinguishing media: Water; dry chemical fire extinguishers; carbon dioxide fire extinguishers.  

SPECIAL HAZARDS ARISING FROM THE SUBSTANCE OR MIXTURE

- Hazardous Combustion Products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating.  

- Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation.  Do not permit dust to accumulate. When suspended in air dust can pose an explosion hazard.  Minimise ignition sources. If dust layers are exposed to elevated temperatures, spontaneous combustion may occur.  

ADVICE FOR FIREFIGHTERS

- Fire Fighting Procedures: Keep people away.  Isolate fire and deny unnecessary entry.  Soak thoroughly with water to cool and prevent re-ignition.  Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of re-ignition has passed.  Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles.  Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container.  Hand held dry chemical or carbon dioxide extinguishers may be used for small fires.  Dust explosion hazard may result from forceful application of fire extinguishing agents.  Move container from fire area if this is possible without hazard.  Contain fire water run-off if possible. Fire water run-off, if not contained, may cause environmental damage.  

- Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing apparatus (SCBA) and protective firefighting clothing (includes firefighting helmet, coat, trousers, boots and gloves).  If protective equipment is not available or not used, fight fire from a protected location or safe distance.  

Accidental release measures

PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES

Evacuate area.  Refer to information on handling for additional precautionary measures.  Only trained and properly protected personnel must be involved in clean-up operations.  Keep upwind of the spill.  Spilled material may cause a slipping hazard.  Ventilate area of leak or spill.  Use appropriate safety equipment. For additional information, refer to information on exposure controls and personal protection.  

ENVIRONMENTAL PRECAUTIONS

Prevent from entering into soil, ditches, sewers, waterways and/or groundwater.

METHODS AND MATERIALS FOR CONTAINMENT AND CLEANING UP

Contain spilled material if possible.  Small spills can be swept up and collected in suitable and properly labelled containers. For large spills, contact the registrant for clean-up assistance.  See information on disposal considerations for additional information.  

Handling and storage

PRECAUTIONS FOR SAFE HANDLING

- General Handling: Keep out of reach of children.  Do not get in eyes.  Avoid contact with skin and clothing.  Wash thoroughly after handling.  Avoid breathing vapour.  Use with adequate ventilation.  Keep container closed.  Good housekeeping and controlling of dusts are necessary for safe handling of product.  Keep away from heat, sparks and flame.  See information relating to exposure controls and personal protection.  

CONDITIONS FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES

- Storage: Store in a dry place.  Store in original container.  Do not store near food, foodstuffs, drugs or potable water supplies.  

SPECIFIC END USES

Exposure controls / personal protection

PERSONAL PROTECTION

- Eye/Face Protection: Use chemical goggles.  Chemical goggles should be consistent with EN 166 or equivalent.  

- Skin Protection: Wear clean, body-covering clothing.  

- Hand protection: Use gloves chemically resistant to this material when prolonged or frequently repeated contact could occur.  Use chemical resistant gloves classified under Standard EN374: Protective gloves against chemicals and micro-organisms.  Examples of preferred glove barrier materials include: neoprene, nitrile/butadiene rubber (“nitrile” or “NBR”), polyvinyl chloride (“PVC” or “vinyl”).  When prolonged or frequently repeated contact may occur, a glove is recommended to prevent contact with the solid material.  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.  

- 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, wear respiratory protection when adverse effects, such as respiratory irritation or discomfort have been experienced, or where indicated by your risk assessment process.  For most conditions, no respiratory protection should be needed; however, in dusty atmospheres, use an approved particulate respirator.  Use the following CE approved air-purifying respirator:  Organic vapour cartridge with a particulate pre-filter, type AP2.  

- Ingestion: Use good personal hygiene.  Do not consume or store food in the work area.  Wash hands before smoking or eating.  

ENGINEERING CONTROLS

- Ventilation: 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.

Stability and reactivity

- REACTIVITY: No dangerous reaction known under conditions of normal use.

- CHEMICAL STABILITY: Thermally stable at recommended temperatures and pressures.  

- POSSIBILITY OF HAZARDOUS REACTIONS: Polymerisation will not occur.  

- CONDITIONS TO AVOID: Product decomposes above melting temperature.  Generation of gas during decomposition can cause pressure in closed systems.  

- INCOMPATIBLE MATERIALS: None known.  

- HAZARDOUS DECOMPOSITION PRODUCTS: Decomposition products depend upon temperature, air supply and the presence of other materials.  Toxic gases are released during decomposition.
