Composition / Information on Ingredients

Molybdenum Disulfide (MoS2) (CAS 1317-33-5): 65%
Isopropyl Alcohol (CAS 67-63-0): <35%

See Section 8 (Exposure Controls / Personal Protection) for applicable exposure limits.

First-Aid Measures

Eye Contact: Immediately flush eyes with water for a minimum of 15 minutes, occasionally lifting and lowering the upper lids. Get medical attention promptly. Remove contact lenses, if present, after the first 5 minutes, then continue flushing for at least 15 minutes. (Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.)
Skin Contact: Remove contaminated clothing. Wash skin with soap and water. Get medical attention. Wash clothing separately and clean shoes before reuse.
Inhalation: Rescuers should put on appropriate protective gear. Remove from the area of exposure. Give artificial respiration if not breathing. If breathing is difficult, oxygen may be given by qualified personnel. To prevent aspiration, keep head below knees. Obtain medical attention.
Ingestion: Do not induce vomiting. Call a physician and/or transport to an emergency facility immediately. If vomiting occurs, lean the patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration into the lungs. Never give liquid to a person who is drowsy or has reduced awareness.
Note to Physician: The decision to induce vomiting should be made by a physician. If ingested, material may be aspirated into the lungs and cause chemical pneumonitis. Treat appropriately.

Fire-Fighting Measures

Suitable Extinguishing Media: Water fog, foam, dry chemical, or carbon dioxide (CO2).
Unsuitable Extinguishing Media: Straight or direct water streams.
Fire-Fighting Instructions: Evacuate area. If a leak or spill has not ignited, use water spray to disperse vapors and protect personnel attempting to stop the leak. Prevent runoff from entering streams, sewers, or drinking water supply. Firefighters should use standard protective equipment and, in enclosed spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire-exposed surfaces.
Unusual Fire Hazards: Highly flammable liquid and vapor. Vapors may cause flash fire or explosion and can travel to a source of ignition and flash back. Empty containers retain product residue and can be dangerous. Molybdenum disulfide decomposes on heating, producing toxic fumes of sulfur oxides (SO2) and molybdenum trioxide. Reacts violently with hydrogen peroxide; avoid hydrogen peroxide, potassium nitrate, and stray oxidizers.
Hazardous Combustion Products: Smoke, fume, incomplete combustion products, oxides of carbon.
Flash Point: 12°C (54°F)
Flammable Limits (% by volume in air): LEL 3.0; UEL not established
Autoignition Temperature: >350°C (662°F)

Accidental Release Measures

Notification: Notify relevant authorities in accordance with all applicable regulations. US regulations require reporting releases that exceed the applicable reportable quantity, or oil spills that could reach any waterway. The National Response Center can be reached at (800) 424-8802.
Land Spill: Eliminate all ignition sources. Stop the leak if it can be done without risk. Ground all equipment used. Do not touch or walk through spilled material. Prevent entry into waterways, sewers, basements, or confined areas. A vapor-suppressing foam may be used to reduce vapors. Use clean, non-sparking tools to collect absorbed material; absorb or cover with dry earth, sand, or other non-combustible material and transfer to containers.
Large Spills: Water spray may reduce vapor but may not prevent ignition in closed spaces. Recover by pumping or with a suitable absorbent. Dike far ahead of the liquid spill for later recovery and disposal.
Water Spill: Stop the leak if it can be done without risk. Eliminate sources of ignition. Warn other shipping. Seek specialist advice before using dispersants.
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas.

Handling and Storage

Handling: Avoid contact with eyes. Prevent exposure to ignition sources—use non-sparking tools and explosion-proof equipment. Use only with adequate ventilation, and use proper bonding/grounding procedures. Peroxides may form upon prolonged storage; exposure to light, heat, or air significantly increases peroxide formation. If evaporated to a residue, the peroxide residue and vapor mixture may explode when exposed to heat or shock. Practice good occupational hygiene; launder work clothing separately, not at home. This material is not a static accumulator.
Storage: An ample fire-water supply should be available; a fixed sprinkler/deluge system is recommended. Keep the container closed and handle with care; open slowly to control possible pressure release. Store in a cool, well-ventilated area; outside or detached storage preferred. Storage containers should be grounded and bonded. Protect from direct sunlight.
Suitable Materials and Coatings: Carbon steel; stainless steel; polyester; Teflon; polyethylene; polypropylene; copper bronze; epoxy phenolic; zinc; vinyls.
Unsuitable Materials and Coatings: Aluminum; cast iron; polystyrene; EPDM; Monel; butyl rubber; natural rubber.

Exposure Controls / Personal Protection

OSHA: 400 ppm TWA; 980 mg/m³ TWA
ACGIH: 200 ppm TWA; 400 ppm STEL
NIOSH: 400 ppm TWA; 980 mg/m³ TWA; 500 ppm STEL; 1225 mg/m³ STEL

Engineering Controls: Provide adequate ventilation so exposure limits are not exceeded. Use explosion-proof ventilation equipment.
Respiratory Protection: If engineering controls do not maintain airborne concentrations at a level adequate to protect worker health, an approved respirator may be appropriate—half-face filter respirator, or an approved supplied-air respirator operated in positive-pressure mode for high concentrations.
Hand Protection: If prolonged or repeated contact is likely, chemical-resistant gloves are recommended; gauntlet-style gloves if forearm contact is likely.
Eye Protection: Chemical goggles recommended. Emergency eyewash should be available within the immediate work area.
Skin and Body Protection: If prolonged or repeated contact is likely, chemical- and oil-resistant clothing is recommended.
Decontamination Facilities: Eye bath, washing facilities, safety shower.
