ETHYL BENZENE

CAS: 100-41-4

Fraction By Weight: 100%

Reports of Carcinogenicity:NTP:No IARC:Yes OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, difficulty breathing, headache, symptoms of
drunkenness, coma LONG TERM EXPOSURE: drowsiness, liver damage SKIN
CONTACT: SHORT TERM EXPOSURE: irritation (possibly severe),
absorption may occur, symptoms of drunkenness LONG TERM EXPOSURE:
blisters, rash EYE CONTACT: SHORT TERM EXPOSURE: irritation,
tearing, eye damage LONG TERM EXPOSURE: same as effects reported in
short term exposure INGESTION: SHORT TERM EXPOSURE: nausea,
vomiting, stomach pain LONG TERM EXPOSURE: no information on
significant adverse effects
Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. Get immediate medical attention. SKIN CONTACT:
Wash skin with soap and water for at least 15 minutes while
removing contaminated clothing and shoes. Get immediate medical
attention. Thoroughly clean and dry contaminated clothing and shoes
before reuse. Destroy contaminated shoes. EYE CONTACT: Flush eyes
with plenty of water for at least 15 minutes. Then get immediate
medical attention. INGESTION: Contact local poison control center
or physician immediately. Never make an unconscious person vomit or
drink fluids. When vomiting occurs, keep head lower than hips to
help prevent aspiration. If person is unconscious, turn head to
side. Get medical attention immediately. NOTE TO PHYSICIAN: For
inhalation, consider oxygen. For ingestion, consider gastric
lavage and activated charcoal slurry.

Flash Point:59 F (15 C) (CC)
Autoignition Temp:810 F (432 C)
Lower Limits:0.8%
Upper Limits:6.7%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam Large fires: Use regular foam or flood with fine water
spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. Withdraw immediately in case of rising sound from
venting safety device or any discoloration of tanks due to fire.
For tank, rail car or tank truck: Evacuation radius: 800 meters
(1/2 mile). Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive above flash point. The vapor is heavier than air.
Vapors or gases may ignite at distant ignition sources and flash
back. Electrostatic discharges may be generated by flow or
agitation resulting in ignition or explosion.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Store outside or in a detached building. Store with
flammable liquids. Subject to storage regulations: U.S. OSHA 29 CFR
1910.106. Grounding and bonding required. Keep separated from
incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 800 ppm Any
chemical cartridge respirator with organic vapor cartridge(s). Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any powered, air-purifying respirator with organic vapor
cartridge(s). Any supplied-air respirator. Any self-contained
breathing apparatus with a full facepiece. Escape - Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any appropriate escape-type, self-contained breathing
apparatus. For Unknown Concentrations or Immediately Dangerous to
Life or Health - Any supplied-air respirator with full facepiece
and operated in a pressure-demand or other positive-pressure mode
in combination with a separate escape supply. Any self-contained
breathing apparatus with a full facepiece.
Ventilation:Ventilation equipment should be explosion-resistant if
explosive concentrations of material are present. Provide local
exhaust ventilation system. Ensure compliance with applicable
exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
