The ChemDAQ® Steri-Trac® gas monitoring system can be used as a safe-entry or safe-area system that provides the continuous detection of dangerous sterilisation gases including Peracetic Acid and Hydrogen Peroxide.

Product Description

Details

Peracetic acid (PAA) is a liquid sterilant that is used in;

  • Treatment of bottles and beverage containers prior to filling
  • Poultry, meat, seafood, fruits, vegetables and other food items to prevent foodborne illnesses
  • Wastewater treatment facilities during water purification process prior to discharge
  • Fracking, gas and oil operations as antimicrobial
  • Eliminate powdery mildew on plants
  • Disinfection of medical devices in hospitals and manufacturing

Overexposure to PAA can cause severe physiological effects

  • Irritation and burning of the skin and eyes leading to eye damage
  • Irritation of the nose and throat
  • Irritation of the lungs causing coughing and shortness of breath

To provide protection against workers, a1-cbiss supply the Steri-Trac continuous gas monitoring system manufactured by ChemDAQ®.

Reliable Means of Employee Protection

The ChemDAQ® Steri-Trac® area detector can power up to three remote display repeaters providing workers with an indication that a room is safe prior to entry.

The ChemDAQ® Steri-Trac® is also configurable to support 28 different gases including Ethylene Oxide, Hydrogen Peroxide and Ozone.

The Steri-Trac® sensors communicate with the DAQ (Data Acquisition) module where the real-time readings are calculated and reported into short and long term exposure limits.

Peracetic Acid Monitoring & Alarms

The Steri-Trac® gas sensors display an intuitive scale of LED's to present gas concentrations. The gas sensors also feature clear audible and visual alerts.

• Low alarm results in a flashing yellow display and pulsing alarm horn.
• High alarm results in a flashing red display and continuous alarm horn

Relay outputs provide simple alarms or more sophisticated controlled fan/airflow systems.

Reduce Downtime with Sensor Exchange Program (SXP)

The use of ChemDAQ®'s sensor exchange program utilises exchangeable EnviroCell™ sensor modules for reliable and accurate gas readings. The program provides factory calibrated sensors every 4 months to avoid sensor drift and eliminates the need for calibration.

Regulations/ Guidelines for Peracetic Acid

Exposure limits and guidelines when using peracetic acid disinfection have been set by a number of national agencies including the following.  Make sure to follow these for proper PAA safety and training of staff:

CAL-OSHA: Proposed limits
15-minute STEL of 0.4 ppm
8-hour PEL of 0.15 ppm

How can you measure Peracetic Acid separately from Hydrogen peroxide, isn’t there hydrogen peroxide in PAA?

Peracetic acid (PAA) is formed in an equilibrium mixture with hydrogen peroxide and acetic acid, so in a mixture of PAA, hydrogen peroxide and acetic acid, PAA is being continually formed by the reaction of hydrogen peroxide and acetic acid, and peracetic acid is continually breaking down to reform hydrogen peroxide and acetic acid.

CH3CO2H  +  H2O2  => CH3COOOH  +  H2O

CH3COOOH  +  H2O =>CH3CO2H  +  H2O2

The kinetics of this reaction are quite slow, so absent a catalyst, the reaction takes days or weeks, which for most gas detection applications, means that the mixture behaves as a simple solution of the three components, i.e. the PAA does not turn into hydrogen peroxide in the timescale of gas detection. The solution thus contains both PAA and hydrogen peroxide, and both will contribute to the vapour, but PAA is the more hazardous component. The PAA sensor thus needs to detect PAA selectively and not respond to hydrogen peroxide.

PAA and hydrogen peroxide are both strong oxidizing agents and so the bare sensor will respond to both of them, however, ChemDAQ sensors have a chemical filter in front of the sensor which removes at least 99% of the hydrogen peroxide vapour. Thus ChemDAQ’s PAA sensors do indeed respond just to the PAA and not the hydrogen peroxide.
