3. Hazards Identification
Health Hazards

Eyes: Likely to cause minor irritation if splashed into the eye with short-term redness and
stinging.

Skin: May cause irritation on brief or occasional contact; prolonged, repeated and heavy
direct contact with the skin over a long period of time can cause de-fatting of the skin,
erythema, dermatitis, oil acne.

Inhalation: No hazards associated in normal operations. Inhalation of vapours or fumes
may cause headaches, nausea, drowsiness, and irritation to the breathing passages and
lungs with possible effects to the central nervous system. As gasoline contains benzene
which is a known carcinogen, continuous exposure to high levels of vapours may be toxic
and in extreme cases may lead to leukemia.

Ingestion: Likely to cause nausea and diarrohoea if small amounts are swallowed; large
amounts may effect the central nervous system.. Signs and symptoms of nervous system
effects may include one or more of the following:-

Headaches, dizziness, loss of appetite, weakness and loss of concentration

The product can be harmful due to aspiration of liquid into the lungs following ingestion
which may cause chemical pneumonitis and can be fatal.

Safety Hazards: Highly flammable liquid. Highly volatile, may form flammable or explosive
vapour-air mixtures from uncontrolled release.

Environmental hazard: Classed as Dangerous for the Environment under EU criteria.

4. First Aid Measures
Eye Contact:
Flush eyes immediately with clean water for 15 minutes. Seek medical advice if adverse eye
effects follow.

P.O.Box 3568 Ruwi, Postal Code: 112, Muscat, Sultanate of Oman

Skin Contact:
Wash skin immediately with soap and water. Do not use solvents or thinners. Remove
heavily contaminated clothing immediately to a safe area due to the risk of fire; ensure
contamination is removed. Seek medical attention, if irritation persists..

Inhalation: If inhalation of fumes irritates the nose, throat or causes coughing remove to
fresh air. Get medical advice. If necessary administer artificial respiration (mouth to mouth)
or give oxygen. Get medical attention immediately.

Ingestion: Do not induce vomiting because of dangers of aspiration. Wash out mouth with
water. Get medical advice immediately. Give water or milk to drink.

5. Fire Fighting Measures

Extinguishing media Foam, dry chemical powder, carbon dioxide
Fire & Explosion Hazards Extremely flammable, high hazard. Liquid can release
vapour at temperatures below ambient, which form
flammable mixtures. Vapours settle to ground level and
may reach ignition sources remote from the point of escape
via drains and other underground passages. Static
discharge, material can accumulate static charges which
may cause an incendiary electrical discharge.
Special Fire-Fighting Water fog or spray to cool fire-exposed surfaces (eg
Procedures containers) and to protect personnel. Only personnel
trained in fire fighting should use water sprays. Respiratory
and eye protection required for fire-fighting personnel
exposed to fumes or smoke.
Hazardous Combustion Smoke, sulphur oxides and carbon monoxide in the event of
Products incomplete combustion

6. Accidental Release Measures

Personal Prevent skin and eye contact. Remove ignition sources and ensure
Precautions sufficient ventilation. The product may damage tarmacadam and make
surfaces slippery. Evacuate all unnecessary personnel. Where ventilation
is inadequate wear breathing apparatus. ( Section -8)

Environmental Land spill: Eliminate sources of ignition; warn occupants downwind of
Precautions fire / explosion hazard. Shut off source if possible. Prevent access to
drains, sewers, waterways and soil. Gasoline vapours are heavier than
air and will collect in drains, gulley etc. Advise authority of soil /
vegetation contamination if necessary. Take measures to minimize
groundwater contamination.

Water spill: Eliminate sources of ignition. Advise shipping of hazard;
notify Port authority. Do not confine in area of leakage. Remove from
surfaces by skimming or suitable absorbents.

Decontamination Procedure:

Use absorbent material e.g. sand, saw dust and earth. Dispose of in accordance with current
waste disposal regulations.

7. Handling and Storage
The design and operation of bulk storage and fuel systems must comply with national
legislation and recognized codes of good practice. In smaller quantities, containers such as
drums should be stored in cool, well ventilated surroundings, away from all sources of
ignition. Electrical equipment and fittings must comply with local fire prevention
regulations for this class of flammable product.

Load/ unload temperature Ambient to 40 Deg.C
Storage temperature Ambient to 40 deg.C

Special precautions:
Use the correct grounding procedure. Store and handle in closed or properly vented
containers. Ensure compliance with statutory requirements for storage and handling. Check
for and prevent potential leaks from containers.

8. Exposure Controls/ Personal Protection
Workplace Exposure Limits:
Substance 8 ?Chout TWA STEL Source/ other information
Benzene 1 ppm HSE work place exposure limits (EH40)
n-Hexane 20 ppm HSE work place exposure limits (EH40)
( 72 mg/m3
Methyl-tert- 25 ppm 75 ppm HSE work place exposure limits (EH40)
butyl ether ( 90mg/m3) (275 mg/m3)

Engineering Measures; Any electrically operated ventilation equipment must be approved
for use in potentially explosive atmospheres by an EC Notified body.

Personal Protection:_
If frequent or continuous contact is likely protective clothing eg chemical resistant overalls
or apron, safety goggles (EN 166) and chemical impervious gloves and protective boots must
be worn. Any contaminated clothing should be laundered before reuse. If contact is likely
protective gloves (nitrile rubber or neoprene) must be worn. Ensure gloves are approved to
relevant standards eg EN 374 in Europe. If possibility of splashing occurs safety glasses or
safety goggles should be worn.

Inhalation: Ensure good ventilation, where ventilation is inadequate, wear breathing
apparatus.

11. Toxicological Information
The following toxicological assessment is based on knowledge of the toxicity of the
product??s components??.

Health Effects:

Acute Based on animal testing data from similar materials and products, the
acute toxicity of this product is expected to be:

ORAL ( rat) LD50> 5000 mg/kg ( slightly toxic)
INHALATION (rat) LD50> 2500 mg/kg ( moderately toxic)
DERMAL ( rabbit) LD50> 2000 mg/kg ( moderately toxic)

12. Ecological Information
Product classed as dangerous for the environment. On release to water gasoline floats on the
surface and hydrocarbons are lost through volatilization. Toxic to fish and invertebrates.

Ecotoxicty Some components of gasoline are water soluble and harmful to aquatic
organisms. Acute aquatic toxicities of gasoline ( as LL50) are in the
range 1-10 mg/l
Mobility Where product enters soil it will be mobile and may contaminate
ground water.
Persistence and Rapid removal of gasoline from the environment result from a
degradability combination of evaporation, physical partitioning with flowing water
and degradation. Volatile components are photo degraded in air by
reaction with hydroxyl radicals.
Biodegradability From the known properties of hydrocarbon components, gasoline is
expected to be inherently biodegradable.

13. Disposal Considerations
Place contaminated materials / packaging in suitable containers and dispose of as Special
waste in accordance with Duty of Care Regulations { Environmental Protection Act 1990-
section 34(7) }using a licensed waste disposal company.
