Wd-40 MSDS Safety

Primarily used to lubricate and prevent rust by displacing moisture, WD-40 is a hydrocarbon-based penetrating oil. It is touted as having hundreds of different uses around the home and in industry. The Material Safety Data Sheet for WD-40 identifies the product's characteristics, contents, hazards and first aid procedures if an accident associated with using the spray oil occurs.

  1. Hazards

    • WD-40’s primary component is oil. It is stored under pressure in an aerosol can and is highly flammable if exposed to an open flame. Lung damage is possible if inhaled. Ingestion may cause nausea, vomiting or diarrhea. The aerosol irritates the eyes and should be flushed with fresh water if contact occurs. WD-40 is intended for use in well-ventilated areas, away from heat sources or open flames, and sprayed away from the face.

    Composition

    • Contents include more than 80 percent petroleum-based (hydrocarbon) oils. Carbon dioxide and surfactants are used push the product out of the can when the trigger is depressed and to help coat the objects where WD-40 is applied.

    First Aid

    • If ingestion occurs, vomiting should not be induced. Inducing vomiting after swallowing a poison or hazardous substance increases the chances for toxins to enter the bloodstream. Instead, contact the poison hotline at 1-888-324-7596 for instructions. Any form of contact with WD-40 that results in irritation is best dealt with by moving into fresh air, and thoroughly flushing the area with fresh water. If irritation or breathing problems continue, call a physician immediately.

    Personal Protection

    • Adequate protective clothing and safety measures when using WD-40 include gloves and a long sleeve shirt to reduce exposure to skin and eyes. Breathing masks are not required if spray oil is used outdoors in a well-ventilated area. Keep in mind that the user is not the only person susceptible to exposure when this product is used. Bystanders, who must be in the immediate area, likewise must take adequate precautions to prevent contact.

    Handling and Storage

    • WD-40 storage recommendations specify cans be stored in a dry, cool, environment. Heat sources or open flames possess significant hazards when WD-40 is stored or handled in the same general area. Electrical components must be unplugged or electrical power otherwise isolated before using the spray oil on, or near, open coils or windings. Electrical current may cause the can to puncture and violently explode, resulting in injury or death. Common sense when using WD-40, or any aerosol or flammable substance, is the best defense against accidents or injuries.
