Agricultural Tailgate Safety Training for Operators and Supervisors

Objective: To observe the needed safety precautions when spray painting.

Trainer’s Note

Discuss the importance of wearing a face respirator while spraying paint. Ask an experienced worker to demonstrate the proper way to adjust the respirator. For more information on personal protective clothing or respirators, refer to training module “Respirator Fit Test.” Review the true or false quiz.


Take the following precautions when spraying paint, lacquer, varnish, or other similar coatings. Spraying paint in a specially constructed and ventilated booth or in the open air protects workers from hazardous fumes and reduces the chance of a fire or explosion. Ventilate spray booths so that fresh air moves from the worker to the exhaust outlet. The linear air movement in a small booth must be at least 100 feet per minute; in larger booths the rate is at least 150 linear feet per minute. This is the standard ventilation rate. Monitor the movement with gauges. Wear an appropriate face respirator. In some cases, a respirator helmet fed by an airline may have to be worn.

Commonly Overlooked Safety Precautions

  • Heat sources combined with paint can be very dangerous because heat can increase the likelihood of fumes and vapors.
  • Do not use electrical extension cords in or around spray booths.
  • Ground equipment that may generate static electricity.
  • Remove or repair any object that could produce a spark in the painting area. Cover exposed light bulbs.
  • Wear protective clothing and equipment.
  • Wash thoroughly after each painting session.
  • Solvent spills should be cleaned up immediately.
  • Store paints, solvents, and thinners in a fire-resistant container.

Review the Following Points

  • Use ventilated booths if available, if not paint in open spaces.
  • Wear proper protective clothing.
  • Use a respirator face mask.
  • Do not use any electric cords in or near the paint booth.
