SLACK WAX IS A NON-VOLATILE VISCOUS LIQUID AND/OR TRANSLUCENT SOLID WAX OF LOW WATER
SOLUBILITY. THIS PRODUCT IS NOT A COMBUSTIBLE LIQUID PER THE OSHA HAZARD COMMUNICATION
STANDARD, BUT WILL IGNITE AND BURN AT TEMPERATURES EXCEEDING THE FLASH POINT.
OSHA WARNING LABEL:
THIS PRODUCT HAS BEEN EVALUATED AND DOES NOT REQUIRE ANY HAZARD WARNING LABEL UNDER
THE OSHA HAZARD COMMUNICATION STANDARD.

CONSUMER WARNING LABEL:
A CONSUMER WARNING LABEL IS NOT APPLICABLE FOR THIS PRODUCT.
Inhalation: Exposure to vapors or mists of this product is not likely.
Ingestion: Product has a low order of acute toxicity. This is based on data from components or
similar products.
Skin contact: Prolonged or repeated liquid contact can cause dermatitis, folliculitis or oil acne.
Dermal contact with hot wax could result in thermal burns if overheated when
shipped.
Eye contact: Liquid or vapor contact may result in slight eye irritation.
Carcinogenic Evaluation:

4. FIRST AID MEASURES
Inhalation: If affected, move person to fresh air. If breathing is difficult, administer oxygen. If not
breathing or if no heartbeat, give artificial respiration or cardiopulmonary
resuscitation (CPR). Immediately call a physician. If symptoms or irritation occur with
any exposure, call a physician.
Skin contact: Wash with soap and large amounts of water. Remove contaminated clothing. If
symptoms or irritation occur, call a physician.
Ingestion: Not expected to be acutely toxic. If large amounts are swallowed, immediately call a
physician.
Eye contact: Flush eyes with large amounts of tepid water for at least 15 minutes. If symptoms or
irritation occur, call a physician.
Medical conditions aggravated No data available.
by exposure:
5. FIRE FIGHTING MEASURES
Suitable extinguishing media: For small fires, Class B fire extinguishing media such as
CO2, dry chemical, foam (AFFF/ATC) or water spray can be
used. For large fires, water spray, fog or foam (AFFF/ATC)
can be used. Fire fighting should be attempted only by those
who are adequately trained and equipped with proper
protective equipment.
Specific hazards: This product is not a combustible liquid per the OSHA
Hazard Communication Standard, but will ignite and burn at
temperatures exceeding the flash point.
MSDS ID NO.: 0235MAR019 Product name: Marathon 325 Slack Wax Page 2 of 6
Special protective equipment for firefighters: Avoid using straight water streams. Water spray and foam
(AFFF/ATC) must be applied carefully to avoid frothing and
from as far a distance as possible. Avoid excessive water
spray application. Use water spray to cool exposed surfaces
from as far a distance as possible. Keep run-off water out of
sewers and water sources.
Flash point: >425 F
Autoignition temperature: No data available.
Flammable limits in air - lower (%): No data available.

Other: - Special: *See Section 8 for guidance in selection of
personal protective equipment.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Keep public away. Isolate and evacuate area. Shut off source if safe to do so.
Eliminate all ignition sources. Advise authorities and National Response Center (800-
424-8802) if the product has entered a water course or sewer. Notify local health
and pollution control agencies, if appropriate. Contain liquid with sand or soil.
Recover and return product to source. Use suitable absorbent materials such as
vermiculite, sand, or clay to clean up residual liquids.
7. HANDLING AND STORAGE
Handling:
Comply with all applicable EPA, OSHA, NFPA and consistent state and local requirements. Use appropriate grounding
and bonding practices. Store in properly closed containers that are appropriately labeled and in a cool well-ventilated
area. Do not cut, drill, grind or weld on empty containers since they may contain explosive residues. Do not expose to
heat, open flames, strong oxidizers or other sources of ignition.
Avoid repeated and prolonged skin contact. Exercise good personal hygiene including removal of soiled clothing and
prompt washing with soap and water.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
PERSONAL PROTECTIVE EQUIPMENT
Engineering measures: Local or general exhaust required when using at elevated temperatures that
generate vapors or mists.
Respiratory protection: Not required under normal conditions and adequate ventilation. Approved organic
vapor chemical cartridge or supplied air respirators should be worn when significant
vapors are generated. Observe respirator protection factor criteria cited in ANSI
Z88.2. Self-contained breathing apparatus should be used for fire fighting.
Skin and body protection: Use chemical resistant gloves such as neoprene, nitrile, or PVA to prevent prolonged
or repeated skin contact.
Eye protection: No special eye protection is normally required.
