Ozone - O3 

Hazard:                      Flammable       Non-Flammable, Oxidizer

Classification:          Health                Extremely toxic

Synonyms:                Triatomic oxygen

Exposure limits:       (OSHA) PEL\TWA: 0.1 ppm

                                    (ACGIH) STEL: 0.3 ppm

                                    (OSHA) IDLH: 5 ppm  

Industries:                 WWTP, Power Generation, Welding

Ozone is a non-flammable gas that is typically colorless to blue in color. It has a very pungent odor. It is a powerful oxidizer and should be kept away form all oxidizable materials both organic and inorganic. Ozone is typically formed around high-powered electrical equipment where sparking is evident. Ozone attacks the eyes and respiratory system and can cause pulmonary edema. Victims should be removed from the area immediately and given 100% oxygen.

Effects of Various O3 Levels  

Ozone Level in PPM                            Resulting Conditions on Humans

0.1                                                 OSHA Permissible Exposure Limit (PEL).

0.3                                                 OSHA Short Term Exposure Limit (STEL)

36                                                  Diarrhea, nausea, respiratory distress.

501                                                Lethal after 45 minutes

2000                                              Lethal after 1-3 minutes
