Chemicals and Fluids Safety

Many of the chemicals and fluids used in auto repair are toxic, corrosive, or flammable. While they're effective for use with automobiles, skin contact or inhalation can be hazardous.

The dangers of chemicals and fluids in auto repair

Many dangers arise from the use of toxic, corrosive, and flammable substances in auto repair. These dangers include both risks of physical exposure and fire hazards.

  • Exposure to solvents such as degreasers can irritate the skin and cause eye damage.
  • Exposure to automotive oils and lubricants can cause skin damage and cancer.
  • Exposure to chemicals used in spray painting can cause nervous disorders, respiratory issues, and other health problems.
  • Exposure to gasoline and fuels can also cause some forms of cancer.
  • Exposure to cleaning supplies can cause skin and eye irritation, headaches, and respiratory issues.

Some substances used in auto repair are also flammable, and fire safety precautions must also be taken.

Personal Protective Equipment (PPE)

Wear the appropriate protective clothing to protect against skin exposure to corrosive or toxic chemicals. If Safety Data Sheets require respiratory protection, you must be trained in the type of respirator needed and how to wear it properly.

The Safety Data Sheet (SDS) provides respiratory protection requirements.

Proper storage of chemicals and fluids

Always store chemicals and fluids in cool and dry areas. Separate storage cabinets should be used for flammable, corrosive (acids/alkalis), and toxic substances. When in storage, containers should be positioned so that the labels are visible.

Storage areas and cabinets must be able to contain leaks in case containers are damaged or corroded. Storage cabinets should generally be airtight to prevent the release of hazardous fumes and vapors. However, flammable chemicals and fluids should be stored in ventilated cabinets to prevent a buildup of flammable vapors.

Handling chemical spills

Auto repair shops are required to develop spill control plans and train employees in spill control. Chemical spill kits should be kept near chemical storage areas and work areas where chemicals and fuels might be spilled.

Don't try to clean up spills of hazardous chemicals unless you've been trained in spill control procedures. Report the spill to your supervisor instead.

Always wear the required Personal Protective Equipment (PPE) when cleaning up spills. Dispose of rags and other materials used for cleaning up spills in designated airtight containers.

Tips for safely handling chemical spills in auto repair shops.

Hazardous substance labeling requirements

Chemical suppliers are required to provide information on health hazards and safety advice. This information should be present in the label on a container. Safety Data Sheets (SDS) also provide detailed information on the hazards posed by chemicals, as well as the steps you should take to protect yourself. This information should be posted and clearly visible around auto repair shops.
