Guidance on Safe Use

First-aid measures

IN CASE OF SERIOUS OR PERSISTENT CONDITIONS, CALL A DOCTOR OR EMERGENTCY MEDICAL CARE.

Inhalation: Remove to fresh air. Symptoms: Euphoria. Intoxication. Headaches. Nausea. Vomiting. At high concentrations: Dizziness. Drowsiness. Weariness. Fainting.  

Ingestion:  Do not induce vomiting to avoid the risk of aspiration into the respiratory tract. Get medical attention immediately! Symptoms: Irritiation of the digestive system. In the event of ingestion with bronchial inhalation: Pneumonopathy with respiratory distress.

Skin contact: Immediately remove all soiled or stained clothing. Wash immediately with plenty of water. In case of repeated or prolonged contact with the skin: Dryness. Chapping.

Eye contact:  Flush immediately with plenty of running water. Symptoms: Eye irritation (lachrymation, conjunctivitis).

Aspiration:  If the product is believed to have entered the lungs (in case of vomiting, for example), take the person to hospital for immediate care.                                                                                                                                              

Fire-fighting measures

Flash point: see "Physical and chemical properties"

Extinguishing media:  - suitable: Carbon dioxide, dry chemicals, foam.  - not recommended: Water jet.

Specific fire-fighting methods:  Cool any containers exposed to fire, with water spray.      

Specific hazards: Extremely flammable. Vapours are heavier than air and may spread on the ground to sources of ignition. Vapours can build explosive mixtures with air. Incomplete combustion and thermolysis may produce gases of varying toxicity such as carbon monoxide, carbon dioxide, various hydrocarbons, aldehydes and soot. These may be highly dangerous if inhaled.                                  

Protective measures for fire-fighters:  Insulated breathing apparatus must be worn in confined premises with heavy concentrations of fumes and

gases. Appropriate protective clothing.

Other: All combustion residues and contaminated water from fire-fighting should be disposed of according to local regulations.

                                                                                                                                                                                             

Accidental release measures

Personal protection: In case of spill in closed area, clear this area. Ventilate thoroughly and let qualified personnel intervene. Hydrocarbon-proof gloves, goggles, boots, and clothing should be worn, as applicable to risks of exposure.

After spillage/leakage: Stop the leak by turning off the valve. Contain the spilled product. Do not allow the product to enter sewers or rivers or contaminate the soil. Contact the competent authorities if the situation cannot be brought under control rapidly and efficiently.

Spill cleanup methods: - Recovery: Use flame-proof and explosion-proof material. Contain and collect the spilled product with sand or any other inert absorbent material. Preserve the waste in closed and sealed recipients.

- Elimination: Hand over contaminated materials to an approved collector - see also disposal considerations. Rinse by flooding the surface with water.

Prevention of secondary risks: Eliminate possible causes of ignition. Stop all work that requires an open flame, stop all vehicles, stop all machines and equipment that may cause sparks or flames.

Handling and storage

HANDLING:

Prevention of user exposure: Ventilate extensively if the formation of vapours, fumes, mists or aerosol is a risk. AVOID CONTACT WITH THE SKIN AND MUCOUS MEMBRANES. DO NOT INHALE VAPOURS.

Prevention of fire and explosion: Handle away from any source of ignition (open flame and sparks) and heat (hot manifolds or casings). Use explosion-proof material. Prevent any build-up of static electricity. Do not smoke. Do not use compressed oxygen or air when transferring or pouring the products. Arrange machinery and equipment so as to prevent the sheet of burning product from spreading (retention pits and basins, syphons in the water drainage system). OPERATE ONLY ON COLD AND DEGASSED RESERVOIRS IN VENTILATED PREMISES (TO AVOID RISK OF EXPLOSION).

Precautions: WHILE MOVING THE PRODUCT: to prevent risks related to static electricity, ensure that the machinery, equipment and tanks are properly earthed, prohibit splash loading and ensure that the product is poured slowly, particularly at the beginning of the operation. Do not spray at high pressure (>3 bar). Avoid breathing in vapours, fumes or mists. Avoid extended and repeated contact with the skin as this may cause skin conditions.

STORAGE:

Technical measures: Use blast-proof electrical equipment in danger areas.

Storage precautions: - Suitable: Store away from all souces of ignition and heat. Arrange the machinery and equipment so as to prevent fire from spreading (retention pits and basins, syphons in the drainage system). Containers and equipment must be earthed in order to prevent sparks due to static electricity. Design the installations and take all steps necessary to avoid the pollution of water and soil. Keep containers closed when not in use.

Incompatible products: Dangerous reaction with strong acids and oxidizing agents.

Packaging materials: - Recommended: Steel, stainless steel.

Exposure controls / personal protection

The personal protective equipment (PPE) recommendations apply to the product ITSELF. In case of mixtures or formulations, it is suggested that you contact the relevant PPE suppliers.

Technical measures: Use this product in a well-ventilated atmosphere with explosion-proof equipment.

Occupational exposure limit: n-Pentane (France): VME=1000ppm (3000 mg/m³).  ISOPENTANE (FRANCE): VME=1000ppm (3000 mg/m³). TOTAL FLUIDES recommends an occupational exposure limit (OEL) value for hydrocarbon solvents of 1400 mg/m³ based on the CEFIC-HSPA (Brussels) guideline values determined using the RCP (Reciprocal Calculation Procedure).
