4 - FIRE OR EXPLOSION HAZARD
---------------------------------------------------------------------------------------------
FLASH POINT: Not applicble
MEANS OF EXTINCTION: If water is ineffective, use carbon dioxide, dry chemical or foam.
Water may be sprayed on closed containers to minimize pressure buildup.
CONDITIONS OF FLAMMABILITY: Heat or ignition sources eg sparks, flame, lit cigarettes.
HAZARDOUS COMBUSTION PRODUCTS: Smoke, fumes, oxides of carbon and sulfur.
5 - TOXICOLOGICAL PROPERTIES
---------------------------------------------------------------------------------------------
ROUTES OF ENTRY: SKIN CONTACT, INHALATION, INGESTION, EYE CONTACT
ACUTE EXPOSURE EFFECTS: EYES: May cause irritation on contact. SKIN: May cause irritation
or inflamation. INHALATION: Overexposure may cause headache, dizziness, drowsiness,
coughing or irritation of the respiratory system. INGESTION: May cause nausea, vomiting,
irritation of the intestinal tract or more serious injury depending on the quantity
ingested. The TLV for crystalline silica is 0.1 mg/m3.
CHRONIC EXPOSURE EFFECTS: Overexposure may cause dermatitis, asthma, skin and respiratory
sensitization and decreased lung function. May aggravate persons sensitized to amines.
Asphalt by itself is considered non hazardous. However when mixed with solvent the hazards
by skin contact or spraying are increaesd. Asphalt may cause rashes or skin sensitivity.
Repeated overexposure to trace chemicals in asphalt may incresae risk of skin or
respiratory cancer unless suitable engineering controls and/or protective equipment are
used. Crystalline silica is a recognized carcinogen by IARC, however it is at low
concentration and is bound so it should not cause significant adverse effects.
NOTES: No Information.
6 - FIRST AID: Get immediate medical attention for any significant overexposure
---------------------------------------------------------------------------------------------
GENERAL FIRST AID: EYES: Flush with water for at least 15 minutes while holding eyelids
apart. Get medical attention immediately after. INGESTION: Do not induce vomiting. Call
nearest Poison Control Center (for Toronto call 416-813-5900). If conscious 1-2 ounces of
water may be given. Do not provide large amounts of liquid unless advised by physician.
INHALATION: Remove person from exposure. Avoid further overexposure. Provide artificial
respiration if necessary. SKIN: Clean with handcleaner, then with soap and water.

8 - PREVENTIVE MEASURES
---------------------------------------------------------------------------------------------
PERSONAL PROTECTIVE EQUIPMENT: Use professional judgement in selection, care and use.
EYES: Use suitable eye protection, eg safety glasses, goggles or face shield if eye contact
is possible. Do not wear contact lenses. Have eyewash facility readily available. SKIN:
Use suitable impervious nitrile gloves and protective apparel to reduce exposure.
RESPIRATION: Use a NIOSH/MSHA approved organic vapour respirator if Engineering Controls
are inadequate.
ENGINEERING CONTROLS: Reduce vapours below the TLV with maximum general ventilation and or
local exhaust. Use full engineering controls before relying on PPE.
SPILLS LEAKS AND WASTE DISPOSAL: Use personal protective equipment. REMOVE SOURCES OF
IGNITION IMMEDIATELY. Scoop up or absorb with inert material and transfer to suitable
container for disposal. Dispose as HAZARDOUS WASTE according to all local, provincial and
federal regulations.
HANDLING AND STORAGE PROCEDURES: KEEP OUT OF REACH OF CHILDREN. FOR INDUSTRIAL USE ONLY.
Avoid heat and all ignition sources, eg: sparks, flame, cigarettes etc. during
transportation, storage, handling and application. Use spark proof tools and explosion
proof equipment if conditions warrant them. Avoid ingestion, inhalation of vapours and
skin or eye contact. Keep skin and apparel clean to reduce exposure. Use personal
protective equipment for spills, cleaning and repair of equipment. Precautions apply also
to empty containers. Seal containers when not in use. Store in sealed containers in a
cool, ventilated area away from all ignition sources.
