It’s no secret that ozone generators are used in a variety of settings to improve air quality. But did you know that using ozone generators in the workplace can be dangerous if used improperly? In this blog post, we’ll take a look at how you can ensure workplace safety while using ozone treatment. Stay tuned!


The most efficient approach of lowering exposure of chemical is through Engineering Controls. Enclosing processes and/or providing local exhaust ventilation at the site of chemical release is the greatest defense.

Although respiratory protection or safety equipment is less effective than the aforementioned safeguards, it may be necessary in some circumstances.

Workplace Controls & Practices

These practices may assist to minimize hazardous exposures. The following work practices are suggested:

  • Workers who have been exposed to liquefied ozone should promptly change their clothing.
  • For speedy access, hand-operated emergency drinking water stations should be placed in the immediate work area.
  • If there is a chance of skin exposure, emergency shower facilities should be made available.
  • Immediately wash or shower if you come into contact with liquefied Ozone.

Consider: ( 1) how dangerous the substance is, (2) how much of the substance is released into the workplace, and (3) whether skin or eye contact with the material could be harmful. When dealing with highly toxic chemicals or situations where substantial skin, eye, or respiratory exposures are possible, additional restrictions should be in place.

Workplace Exposure Limits of Ozone

Ozone generators are devices that produce ozone, a gas with many industrial and commercial applications. Ozone is used to disinfect water, purify air, and control odors. It is also used in food processing and storage, pharmaceutical manufacturing, and electronic assembly. While ozone has many positive uses, it can also be harmful to human health if inhaled in high concentrations.

For this reason, departments like the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) have issued recommendations on the use of ozone generators in the workplace.

These recommendations include ensuring that ozone generators are properly ventilated, using them only in well-ventilated areas, and avoiding direct skin contact with ozone. By following these recommendations, workers can minimize their exposure to harmful ozone.

OSHA: The permissible exposure limit (PEL) is 0.1 ppm averaged over an 8-hour work shift according to OSHA.

NIOSH: The maximum airborne concentration level is 0.1 ppm, which should never be exceeded under any circumstances.

ACGIH: The permissible exposure levels for heavy work are 0.05 ppm; moderate labor, 0.08 ppm; light labor, 0.1 ppm; and work shifts of less than 2 hours, 0.20 ppm, on average over an 8-hour shift.

Bottom Line

It is important to be safe when using ozone generators. Make sure you read and follow the safety instructions carefully to avoid any injuries or accidents. OSHA and NIOSH have provided recommendations on the use of ozone generators in the workplace. You should carefully consider these recommendations to ensure the safety of your employees.
