Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

HYDROCARBONS, C20 AND GREATER, PETROLEUM WASTES

NFPA

PRODUCT USE

Used as boiler fuel. Residual oils are manufactured in whole or in part from distillation
residues from distillation residues from refinery processing. Residual oils are complex
mixtures of relatively high molecular weight compounds and are difficult to characterize
in detail. Molecular types include asphaltenes, polar aromatics, naphthalene aromatics,
aromatics, saturated hydrocarbons and heteromolecules containing sulfur, oxygen, nitrogen
and metals. Most blending stocks of residual fuel oils are likely to contain 5% or more of
four- to six- ring condensed aromatic hydrocarbons. In residual fuel oils, the identities
and concentration of PAHs depends on the nature and amount of the low viscosity blending
stocks and the proportions of virgin and cracked residues used in their production. If the
blending stocks are primarily atmospheric or vacuum residues, the concentration of three-
to seven- ring aromatic hydrocarbons are likely to be in the order of 6- 8%; if larger
quantities of heavily catalytically cracked or steam cracked components are used, the
levels may approach 20%. One of the blending stocks, catalytically cracked clarified oil
has been reported to contain 58% three- to five- ring aromatic hydrocarbons and 22%
carbazoles and benzocarbazoles.

SYNONYMS

"oily sludge", "waste oil", "slop oil", "gland oil"

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Considered an unlikely route of entry in commercial/industrial environments.  The liquid is.  slightly.  discomforting.  to the gastrointestinal tract.  

EYE

  The liquid is.  slightly.  discomforting.  to the eyes.  

SKIN

  This material can cause inflammation of the skin oncontact in some persons.  The liquid is.  slightly.  discomforting.  to the skin.  if exposure is prolonged.  and is.  capable of causing.  skin reactions.  from repeated exposures over long periods.  which may lead to dermatitis.  

INHALED

  Not normally a hazard due to non-volatile nature of product.  The vapor/mist is.  moderately.  discomforting.  to the upper respiratory tract.  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  There is sufficient evidence to suggest that this materialdirectly causes cancer in humans.  Based on experiments and other information, there is ample evidence to presume that exposure to this material can cause genetic defects that can be inherited.  

  Oil may contact the skin or be inhaled. Extended exposure can lead to eczema, inflammation of hair follicles, pigmentation of the face and warts on the soles of the feet. Exposure to oil mists can cause asthma, pneumonia and scarring of the lungs. Oils have been linked to cancer of the skin and scrotum. Compounds that are less viscous and with smaller molecular weights are more dangerous. There may be liver damage and the lymph nodes may be affected; heart inflammation can also occur at high doses.  Constant or exposure over long periods to mixed hydrocarbons may produce stupor with dizziness, weakness and visual disturbance, weight loss and anemia, and reduced liver and kidney function. Skin exposure may result in drying and cracking and redness of the skin. Chronic exposure to lighter hydrocarbons can cause nerve damage, peripheral neuropathy, bone marrow dysfunction and psychiatric disorders as well as damage the liver and kidneys.  High boiling residues of petroleum process can produce both benign and malignant skin tumors, according to animal testing. They may contain significant concentrations of polynuclear aromatic hydrocarbons (PAHs).  Polycyclic aromatic hydrocarbons are found in a number of materials such as coal tar, tobacco smoke, petroleum and air pollution. Some substituted derivatives have been identified as extremely liable to cause cancer, especially that of the lung and genito-  urinary tract. Some jurisdictions required that health surveillance be conducted on workers occupationally exposed to PHAs.
