Ozone Safety

Ozone in the air is regulated by OSHA (Occupational Safety and Health Administration) and EPA (Environmental Protection Agency). There are also some recommendations from ACIGH (American Conference of Governmental Industrial Hygienists) and NIOSH (National Institute for Occupational Safety and Health). Here you can find some basics from each.

OSHA (Occupational Safety and Health Administration)

OSHA requirements are set by statute, standards and regulations. OSHA requires that if you are generating ozone, you should measure the ozone levels for safety purposes.

Guidelines for Ozone in the workplace
0.3 ppm for no more than 15 minute exposure
0.2 ppm for no more than 2 hours exposure
0.1 ppm for 8 hours per day exposure doing light work
0.08 ppm for 8 hours per day exposure doing moderate work
0.05 ppm for 8 hours per day exposure doing heavy work

OSHA (1982) has established the Federal Standard for O₃ in the workplace based on time-weighted averages (0.1ppm for 8 hours per day exposure).

NIOSH (National Institute for Occupational Safety and Health)

NIOSH establishes standards and recommendations (not enforceable under US law) for health and safety standards that may influence future laws and OSHA regulations.

The NIOSH recommended exposure limit for ozone is 0.1 ppm (0.2 mg/m3). According to NIOSH, Ozone levels of 5 ppm or higher are considered immediately dangerous to life or health.

Respiratory Recommendations NIOSH/OSHA

	UP TO 1 ppm
APF =10	Any chemical cartridge respirator with cartridge(s) providing protection against the compound of concern
APF =10	Any supplied-air respirator

	UP TO 2.5 ppm
APF =25	Any supplied-air respirator operated in a continuous-flow mode
APF =25	Any powered, air-purifying respirator with cartridge(s) providing protection against the compound of concern

	UP TO 5 ppm
APF =50	Any chemical cartridge respirator with a full facepiece and cartridge(s) providing protection against the compound of concern
APF =50	Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted canister providing protection against the compound of concern
APF =50	Any supplied-air respirator that has a tight-fitting facepiece and is operated in a continuous-flow mode
APF =50	Any self-contained breathing apparatus with a full facepiece
APF =50	Any supplied-air respirator with a full facepiece

	Emergency or planned entry into unknown concentrations
APF =10.000	Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode
APF =10.000	Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus

EPA (Environmental Protection Agency)

The EPA Green Book provides detailed information about area NAAQS (National Ambient Air Quality Standards) designations, classifications and nonattainment status.

The EPA measures, track, report and regulates ground level ambient ozone levels in large cities throughout the United States. The European Network of the Heads of Environment Protection Agencies (EPA Network) is an informal grouping bringing together the heads of environment protection agencies and similar bodies across Europe.

EPA STANDARDS
8-hour limit = 0.08 ppm
1-hour limit = 0.12 ppm

**8-Hour Ozone Classifications (according with EPA 2015 Standard)**

Extreme	Area has a design value of 0.163 ppm and above
Severe 17	Area has a design value of 0.111 up to but not including 0.163 ppm
Severe 15	Area has a design value of 0.105 up to but not including 0.111 ppm
Serious	Area has a design value of 0.093 up to but not including 0.105 ppm
Moderate	Area has a design value of 0.081 up to but not including 0.093 ppm
Marginal	Area has a design value of 0.071 up to but not including 0.081 ppm

ACGIH^® (American Conference of Governmental Industrial Hygienists)

ACGIH^® is a charitable scientific organization that advances occupational and environmental health and is dedicated to study of the industrial hygiene and occupational and environmental health and safety communities.

According to ACGIH (1979), the TLV-TWA (Threshold Limit Value–Time-Weighted Average) for ozone is 0.1 ppm and the TLV-STEL (Threshold Limit Value–Short-Term Exposure Limit) is 0.3 ppm. The TLV-TWA for ozone was revised downward from an original recommendation of 1 ppm.

**Ozone exposure limits for 8-Hour workshift (according with ACGIH)**

0.05 ppm	Heavy Work
0.08 ppm	Moderate Work
0.1 ppm	Light Work
0.2 ppm	Workloads <2 hours
0.3 ppm	Workloads <15 minutes
