3. HAZARD IDENTIFICATION
Note: This product has not been tested by El Paso Corporation
to determine its specific health hazards. Therefore, the
information provided in this section includes health
hazard information on the product components.
Carcinogenicity: NTP IARC Monographs OSHA Regulated
Crude Oil No No No
Benzene Yes Yes Yes
Potential Health Effects From Overexposure
Acute Effects
Eyes: Sight to moderate eye irritation.
Skin: Moderately irritating; causes redness, drying of
skin.
Inhalation: Will cause narcosis and/or chemical pneumonitis.
High concentrations of hydrogen sulfide can cause
headache, dizziness, unconsciousness and/or death.
Ingestion: Extremely irritating to throat and stomach. Causes
excitation, loss of consciousness, convulsion,
cyanosis, congestion and capillary hemorrhaging of
the lung and internal organs.
Chronic Effects
Skin irritation. The long-term, repeated application of crude to
the skin of laboratory mice (without washing between applications)
resulted in a statistically significant increase in the incidence
of skin tumors. Crude oil contains benzene, which can cause
degeneration in blood forming organs leading to anemia which may
further degrade to leukemia.
Additional Medical and Toxicological Information
May aggravate pre-existing dermatitis. May cause blood-forming
disorders, or lead to kidney or liver dysfunction. Contact with
full strength or dilute formulations of this product or exposure
above and below exposure limits may aggravate pre-existing
dermatitis or respiratory disorders in certain individuals. This
product contains benzene, which can cause degeneration in blood
forming organs leading to anemia which may further degrade to
leukemia.
4. FIRST AID MEASURES
Eye Contact: Flush thoroughly with large amounts of water for at
least 15 minutes, including under the eyelids. Get
medical attention.
Skin Contact: Remove contaminated clothing. Wash affected areas
with soap and water. If irritation persists, get
medical attention.
Inhalation: Remove to fresh air. If breathing has stopped,
apply artificial respiration. Get medical
attention.
Ingestion: Do not induce vomiting. If spontaneous vomiting
occurs hold the victim's head lower than their hips
to prevent aspiration.
5. FIRE FIGHTING MEASURES
<100oF
Flash Point:
Flammable Limits in Air, % by Volume:
Lower: 1%
Upper: 15%
Autoignition Temperature: Liquid: 450oF Vapor: 800-1000oF
Extinguishing Media: Dry chemical, foam, carbon dioxide.
NFPA Hazard Ratings (crude petroleum):
Health: 1 Flammability: 3 Reactivity: 0
General Hazard:
Flowing crude oil can be ignited by self-generated static
electricity; containers should be bonded and grounded. Runoff to
sewer may create fire or explosion hazard well downstream from the
source.
Fire Fighting Instructions:
Use a smothering technique for extinguishing fire of this flammable
liquid. Do not use a forced water stream directly on crude oil
fires as well this will scatter the fire. Firefighters should wear
self-contained breathing apparatus and full protective clothing.
6. ACCIDENTAL RELEASE
Remove source of heat or ignition including internal combustion
engines and power tools. Clean up spill but do not flush to sewer
or surface water. Ventilate area and avoid breathing vapors or
mists.
7. HANDLING & STORAGE
Store in tightly closed containers in a dry cool place, away from
sources of heat or ignition. Ground and bond all transfer and
storage equipment to prevent static sparks and equip with self-
closing valves, pressure vacuum bungs and flame arrestors. Empty
containers may contain residue (liquid/or vapor) and can be
dangerous. Do not pressurize, cut, weld, braze, solder, drill,
grind or expose such containers to heat, flame, sparks, or other
sources of ignition; the may explode and cause injury or death.
8. EXPOSURE CONTROL, PERSONAL PROTECTION
Eye Protection: Remove contact lenses and wear chemical safety
glasses or goggles where contact with liquid
or mist may occur.
Skin Protection: Wear insulating gloves and protective clothing
when contact with skin may occur. Wash with
soap and water before eating, drinking or
smoking. Launder contaminated clothing before
reuse.
Inhalation: CRUDE OIL MAY CONTAIN HYDROGEN SULFIDE. NIOSH
approved respiratory protection should be used
when handling crude of high or unknown
hydrogen sulfide content and to reduce
airborne concentrations to allowable
occupational exposure levels.
Ventilation: Provide adequate general and local
ventilation: (1) to maintain airborne chemical
concentrations below applicable exposure
limits, (2) to prevent accumulation of
flammable vapors and formation of explosive
atmospheres, and (3) to prevent formation of
oxygen deficient atmospheres, especially in
confined spaces. [Note: this product may
release gases or vapors that can displace
oxygen in enclosed areas.]
