HAZARDOUS INGREDIENTS - WHMIS This product when tested as a whole is not a controlled substance within the meaning of the Hazardous Products Act. ___________________________________________________________________________________________________ 3. HAZARDS IDENTIFICATION

Emergency Overview:

Potential combustible dust if flaked or powdered. Dust generated from flaked product will be combustible at sufficient concentration.

NAME: T-7

Potential Health Effects: Eye Skin Accidental exposure to the eyes will cause only a mild but transient irritation. Mild, primary skin irritation with prolonged or repeated contact. Heated product may cause thermal burns if contacted. Not applicable at ambient temperature. May elicit transient pulmonary irritation if inhaled. May cause irritation of gastrointestinal tract.

Inhalation Ingestion -

If product is heated, vaporization can occur. Eye, skin, and upper respiratory irritation may occur.

Physical/Chemical Hazards:

Potential combustible dust if flaked or powdered. Dust generated from flaked product will be combustible at sufficient concentration.

• Environmental Hazards: None identified ____________________________________________________________________________________________________ 4. FIRST AID MEASURES • • • •

Eye -

In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention. Wash skin with soap and water upon contact. Remove contaminated clothing. If irritation develops, get medical attention. Wash clothing before reuse. Avoid breathing dust. If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately

Skin -

Inhalation -

If swallowed, do not induce vomiting. Get medical attention. Never give anything by mouth to an unconscious person. ______________________________________________________________________________________________________ 5. FIRE FIGHTING MEASURES

Ingestion -

Extinguishing Media:

SMALL FIRES: Use CO2 or dry chemical. LARGE FIRES: Use foam. Do not use water as an extinguishing media.

• • • •

Flash Point: >300° F (>149° C) PMCC Explosive Limits in air: Not determined Auto-ignition temperature: Not determined Other Fire Fighting Considerations: Wear self-contained breathing apparatus and full protective clothing. Cool containers with flooding quantities of water until well after fire is out. Potential combustible dust if flaked or powdered. Dust generated from flaked product will be combustible at sufficient concentration.

NAME: T-7

Personal Precautions:

An appropriate NIOSH/MSHA approved respirator should be used if a mist, vapor or dust is generated. Wear suitable gloves and eye/face protection. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Minimize contamination of drains, surface and ground waters.

• •

Environmental Precautions:

Sweep or shovel solids. For liquid spills, neutralization is not required. Contain spill. Absorb or cover with dry earth, sand or other noncombustible material and transfer to containers for disposal. Dispose as any grease or oily material in compliance with Federal, State, and/or Local requirements. ______________________________________________________________________________________________________ 7. HANDLING AND STORAGE

Procedures for Spill/Leak Clean-up:


Handle in accordance with good hygiene and safety procedures. Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. Since empty containers contain product residue, follow all hazard warnings and precautions even after container is emptied. Keep away from sources of ignition.

Keep away from possible contact with incompatible substances. Store in acid resistant vessels such as stainless steel, aluminum, or steel coated with resin lining such as Lithcote LC-19 or Kanigen. Do not store near sources of ignition. ______________________________________________________________________________________________________ 8. EXPOSURE CONTROLS, PERSONAL PROTECTION
• •



General Precautions:

Good industrial hygiene should be followed. Avoid breathing (heated) vapors. Ventilation: Local exhaust - preferred Mechanical - may be necessary if working at elevated temperatures or in enclosed areas.

Engineering Controls:


Personal Protective Equipment: Eye - Goggles or face shield with goggles, dependent upon potential exposure Skin - Protective gloves: Rubber or plastic Dependent upon degree of potential exposure, additional personal protective equipment may be required, such as chemical boots and full protective clothing. Inhalation - None required for ambient temperature, although an appropriate NIOSH/MSHA approved air-purifying respirator should be used if a mist, vapor or dust is generated. A NIOSH/MSHA approved self-contained breathing apparatus or air-supplied respirator is recommended if the concentration exceeds the capacity of cartridge respirator. WARNING: Air purifying respirators do not protect workers in oxygendeficient atmospheres.

NAME: T-7
• Other Controls: Eye bath, safety shower, apron, protective clothing. ______________________________________________________________________________________________________ 9. PHYSICAL AND CHEMICAL PROPERTIES
