First-aid measures

Inhalation:
Transport the person out of the contaminated area, keep warm and allow to rest.
Get medical attention
Syptoms: Euphoria
At high concentrations: Irritation of eyes (watering, conjunctivitis)
Drowsiness. Headaches. Dizziness. Nausea. Intoxication

Ingestion:
Do not induce vomiting to avoid the risk of aspiration into the respiratory tract.
Get medical attention immediately
Symptoms:
Irritation of the digestive system
Nausea, vomiting,adominal pais, diarrohea
In the extent of ingestion with bronhcial inhalation: Pneumonopathy with respiratory distress

Skin contact:
Immediately remove all soiled or stained clothing
Wash thoroughly with soap and water
-Symptoms: Skin irritation. Erythema, oedema, pruritis

Eye contact:
Wash immediately in copious amounts of water, keeping eyelids apart for at least 15 minuted and consult a specialist.
Symptoms: Conjuncitvitis

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

Extinguisihing media:
Not suitable: Carbon dioxied, dry chemicals, foam
Not recommended: Water jet

Specific hazards:
Highly 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 firefighters:
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 protections:
In case of spill in a 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 broght under control rapidly and efficiently

Spill cleanup methods:
If the material has been discharged in a stream or a sewer, inform the authorities.
-Recovery:
Use flame-proof and explosion-proof material. Containa and collect the spilled product with sand or any other inert absorbent material. Preserve the wastes in closed and sealed recipients.
-Elimination:
Dispose of was in compliance with regulations
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:
Handle in well ventilated premises
Evaluate the vapours at their emission source and generally ventilate the premises.
DO NOT INHALE VAPOURS
AVOID CONTACT WITH THE SKIN AND MUCOUS MEMBRANES
Carry out an appropriate industrial operation using sealed apparatus

Prevention of fire and explosion:
Handle away from any source of ignition. 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 preven 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 electricitry, ensure that the machinery, equipment and tanks are properly earthed, prohibit splash loading and ensure that the product is poured slowly, particuarly at the beginning of the operation.
Do no spray at high pressure (>3 bar)

Storage:
Technical measures: Prevent any build up of static electricity
Storage precautions:- Suitable:
Store away from all sources of ignition and heat.
Containers and equipment must be earthed in order to prevent sparks due to static electricity
Keep containers closed when not in use

Incompatible products: Avoid contact with strong oxidising agents

Packagin materisals:
Recommended: Steel, stainless steel
