Monitoring Peracetic Acid

What You Should Know

Peracetic Acid (Peroxyacetic Acid or PAA) is highly reactive, it leaves no harmful residue, which makes it the chemical of choice when dealing with microbes and bacteria.  Peracetic Acid is an effective biocide/disinfectant, but can pose a risk to workers when exposed to unsafe levels.

Applications for Peracetic Acid

  • Disinfection of bottles and beverage containers
  • Disinfection of poultry, meat, seafood, fruits, vegetables and other food items
  • Waste water treatment facilities
  • Fracking, gas and oil operations 

Keep your employees safe by monitoring peracetic acid in the workplace.

Hazards and Risks

Peracetic Acid is a highly corrosive chemical used in both health care and industrial settings as a highly effective disinfectant.  PAA is highly reactive, it leaves no residue, that is why it is the chemical of choice when dealing with microbes and bacteria.  However, this same reactivity that underlies its benefits also means that excessive exposure to its vapors can be harmful and lead to health issues.  Peracetic Acid has a vinegar type odor, even at low levels, so the challenge becomes knowing if your level of exposure is safe... whether you smell it or not.

  • Eye irritation : eye damage after prolonged exposure

  • Nose and throat irritation

  • Respiratory distress : fluid in the lungs after high level 
    of exposure

  • Skin irritation dermatitis
