Powder Coating Safety

Hazards, Protection, and Safety

TCI Powder Coatings strives to provide our customers with ample information so that you can get the best use and superior results from our products. More importantly, we also hope to ensure that our products are used in a safe and effective manner so that you may maintain a secure environment. The safety of our staff as well as our customers is extremely important to us. Although our website includes a user manual and troubleshooting guide, we want to extend a reminder to you that every organization should examine and develop their own coating operation, safety program, and specified procedures.

Health Hazards of Powder Coating Materials

All chemical manufacturers, according to the OSHA, must evaluate chemicals produced and determine if they are hazardous based on:
  • Carcinogens
  • Toxins
  • Irritants
  • Danger to human organs
  • Flammability
  • Explosiveness
  • Reactivity

This information is available to workers in the material safety data sheets (MSDS).

Respiratory Protection: What mask should I wear?

For small particles (powders), legally the Threshold Limit Value (TLV) of occupational exposure is 10mg/m3. In regards to the TLV, below is a list of the masks that should be worn for specific exposures.

  • Outside of a spray enclosure: disposable dust mask
  • TLV higher than 10mg/m3: half mask with cartridge filter
  • Fully inside of spray enclosure (high powder concentration): full-face mask

Personal Safety

Here are a few reminders to keep you safe during the powder coating process:

  • Use coating and protective eyewear to limit eye and skin exposure
  • Do not wear gloves unless they are specially designed for electrostatic application
  • Make sure all equipment is in proper working order
  • Hold the spray gun in its proper position to ensure grounding
  • Do not blow powder off of the skin using compressed air (it can force abrasive particles into skin and eyes)
  • Practice good housekeeping to reduce accumulation of powder in the area and personal exposure
