Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

VIC ROADS CRUMB RUBBER IN BITUMEN

NFPA

PRODUCT USE

A hot spray roadmaking seal. Using a hand held coarse spray nozzle the liquid is sprayed
at a temperature of 180 - 185 C. Usually handled as molten liquid which requires worker
thermal protection and increases hazard of vapor exposure.CAUTION: Vapors may be
irritating. CARE: Contamination of heated / molten liquid with water may cause violent
steam explosion, with scattering of hot contents.

SYNONYMS

"rubber bitumen cut back rubberised bitumen mix", "road asphalt sealer"

EMERGENCY OVERVIEW

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  Overexposure is unlikely in this form.  Ingestion may result in nausea, abdominal irritation, pain and vomiting.  

EYE

  There is some evidence to suggest that this material can causeeye irritation and damage in some persons.  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  

INHALED

  There is some evidence to suggest that this material, if inhaled, can irritate the throat and lungs of some persons.  Although inhalation is not thought to produce harmful effects, the material may still produce health damage, especially where pre-existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally confined to doses producing mortality (death) rather than those producing morbidity (disease, ill-  health).  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact, eye contact with the hot material and inhalation of vapor from heated material.  Chronic exposure to the bitumen fumes over extended periods may cause  central nervous system depression, liver and kidney damage, intoxication.  Chronic poisoning may result in a decrease in the number of white and red  blood cells.            [ILO Encyclopaedia]  Use strict occupational hygiene practices to avoid all personal contact.
