EC number: 296-942-7 | CAS number: 93165-55-0 A complex combination of hydrocarbons produced from the separation and subsequent hydrogenation of the products of a steam-cracking process to produce ethylene. It consists predominantly of saturated and unsaturated paraffins, cyclic paraffins and cyclic aromatic hydrocarbons having carbon numbers predominantly in the range of C4 through C10 and boiling in the range of approximately 50°C to 200°C (122°F to 392°F). The proportion of benzene hydrocarbons may vary up to 30 wt. % and the stream may also contain small amounts of sulphur and oxygenated compounds.

Harmful if ingested.
Vapours may cause drowsiness or dizziness.
May cause damage to organs through prolonged and repeated exposure.
Suspected of damaging fertility or the unborn child.
General advice :

Take care to self-protect by avoiding becoming contaminated.
Use adequate respiratory protection.
Move contaminated patient(s) out of the dangerous area.
Take off all contaminated clothing and shoes.
Seek medical assistance - show the material safety data sheet or label if possible.
Inhalation :
Move to fresh air.
Do not leave the victim unattended.
Keep patient warm and at rest.
Seek immediate medical attention.
If breathing is difficult, give oxygen if possible or assisted ventilation, (do not use mouth to mouth).
If unconscious place in recovery position.
In the event of cardiac arrest, (no pulse), apply cardiopulmonary resuscitation.
Skin contact :
Take off all contaminated clothing and shoes.
Immediately flush affected area with plenty of soap and water – continue for at least 15 minutes.
If there are signs of irritation or other symptoms seek medical attention.
Eye contact :
Remove any contact lenses.
Flush eyes with water thoroughly and continuously for at least 15 minutes.
Keep eye wide open while rinsing.
Protect unharmed eye.
If there are signs of irritation or other symptoms seek medical attention.
If eye irritation, pain, swelling, lachrimation or photophobia persists, the patient should be seen in a specialist health care facility.
Ingestion :
Do NOT induce vomiting, if vomiting does occur, have victim lean forward to reduce risk of aspiration. Get medical
attention immediately.

Do not give milk or alcoholic beverages.
Never give anything by mouth to an unconscious person.
Advice to Physician :
Causes eye irritation. This irritation can result in redness and swelling of the eyes.
Causes irritation to the skin. This irritation can result in redness and swelling of the skin. Repeated contact with
the skin may cause it to become dry and cracked.
May cause respiratory irritation. If inhalation occurs, signs and symptoms may include sore throat, headache, nausea, coughing, choking, wheezing, difficulty in breathing, chest congestion, shortness of breath and may cause transient central nervous system (CNS) depression.
In case of ingestion, Ipecac-induced emesis is not recommended.
Consider use of charcoal as a slurry (240mL water/30 g charcoal). Usual dose: 25 to 100 g in adults.
If a potentially fatal dose has been ingested the stomach should be emptied by gastric lavage under qualified medical supervision with the airway protected by endotracheal intubation.

Fire-fighting measures
Suitable extinguishing media :
LARGE FIRE: Use water spray, water fog or foam. DO NOT use direct water jet.
SMALL FIRE: Dry powder or carbon dioxide (CO2) extinguisher, dry sand or fire fighting foam.
Unsuitable Extinguishing Media :
(Do Not use) Direct water jet.
Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.
Combustion Products :
Carbon monoxide, carbon dioxide and unburned hydrocarbons (smoke).
Specific hazards during fire fighting :
Vapour is denser than air – flashback may be possible over considerable distances.
Containers may explode under fire conditions - use water spray to cool unopened containers.
Do not allow run-off from fire fighting to enter drains or water courses – may cause explosion hazard in drains and may reignite on surface water.
Further information :
Special protective equipment for fire-fighters :
Wear an approved positive pressure self-contained breathing apparatus in addition to standard fire fighting gear.

Accidental release measures
Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area).
Personal precautions :
Wear personal protective equipment.
Avoid breathing vapours or mist.
Ensure adequate ventilation and absence of sources of ignition.
Beware of accumulation of vapours in low areas or contained areas, where explosive concentrations may occur.
Environmental precautions :
Land spillage :
Prevent further leakage or spillage if safe to do so.
Prevent spillage from entering drains, sewer, basement or confined areas.
Spillages in water or at sea :
Prevent further leakage or spillage if safe to do so.
If the spillage contaminates rivers, lakes or drains inform respective authorities.
Methods for clean up :
Contain spillage.
Small spillages can be taken up by collection with non-combustible absorbent material, (e.g. sand, earth,
diatomaceous earth, vermiculite) and placed in container for disposal according to local / national
regulations.
Water spillage:
If the Flash Point exceeds the Ambient Temperature by 10 deg C or more, use containment booms and remove from the surface by skimming or with suitable absorbents when conditions permit. If the Flash Point does not exceed the Ambient Air Temperature by at least 10 deg C, use booms as a barrier to protect shorelines and allow material to evaporate. Seek the advice of a specialist before using dispersants.
Further accidental release measures :
Spillages of liquid product will create a fire hazard and form an explosive atmosphere.
Ensure all equipment is non sparking or electrically bonded.
Avoid direct contact with released material.
Stay upwind.
Keep non-involved personnel away from the area of spillage.
Ensure adequate ventilation, especially in confined areas.

Keep container tightly closed and properly labelled.
Vapour space above stored liquid may be flammable/explosive unless blanketed with inert gas.
Storage installations should be designed with adequate bunds so as to prevent ground and water pollution in case of leaks or spills.
Fixed storage containers, transfer containers and associated equipment should be earthed and bonded to prevent accumulation of static charge.
Smoking, eating and drinking should be prohibited.
Use only in well ventilated areas.
Avoid all sources of ignition.

Exposure controls / personal protection
Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value. Ensure
that eyewash stations and safety showers are proximal to the work-station location.
Personal Respirators
If the exposure limit is exceeded and engineering controls are not feasible, a half-face organic vapor respirator may be worn for up to ten times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece organic
vapor respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area
Naphtha (petroleum) light steam-cracked, hydrogenated is handled under Strictly Controlled Conditions in accordance withREACH regulation Article 17(3) for on-site isolated intermediates and, in case thesubstance is transported to other sites for further processing, the substance shouldbe handled at these sites under the Strictly Controlled Conditions as specified inREACH regulation Article 18(4). Site documentation to support safe handlingarrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems is
available at each manufacturing site.
