Is Hydrogen Peroxide Gas Dangerous?

Hydrogen peroxide can be hazardous.

Exposure to the chemical compound may cause a number of negative health effects including the following:

  • Eye irritation
  • Throat irritation
  • Respiratory airway irritation
  • Skin irritation
  • Temporary bleaching of skin and/or hair

Monitoring the concentration of hydrogen peroxide gas can help to stave off the worst of the health effects by allowing people to monitor their own exposure and take the steps necessary to reduce their exposure.

What Levels of H2O2 gas is dangerous?

Several agencies have recommended exposure limits, these include:

  • OSHA PEL (permissible exposure limit): 1 ppm (averaged over an 8-hour workshift)
  • NIOSH IDLH (immediately dangerous to life or health) = 75 ppm

What is a Hydrogen Peroxide Detector?

A hydrogen peroxide gas detector, also sometimes called a H2O2 monitor or H2O2 gas meter, is a measurement device used to detect the presence of and monitor changes in hydrogen peroxide gas in the part per million (ppm) scale. Detection of H2O2 is usually performed in an indoor air environment. It is particularly useful in decontamination contexts where hydrogen peroxide gas may be readily used.

What Does a Hydrogen Peroxide Detector Sense?

A Hydrogen peroxide detector is designed to detect the presence of hydrogen peroxide in gas phase. Although hydrogen peroxide is in liquid phase at room temperature, outgassing occurs and can accumulate in the air making it a hazard during human inhalation.

How is a H2O2 Gas Detector Calibrated?

A NIST gas standard for H2O2 gas does not exist, which makes it tricky to calibrate a H2O2 gas detector. A hydrogen peroxide electrochemical sensor has a cross sensitivity of 1:1 with sulfur dioxide gas (SO2) and often used as a surrogate to calibrate H2O2. 

What is Vaporized Hydrogen Peroxide (VHP)?

  • Classrooms, medical and manufacturing facilities, confined spaces, and other areas meant for continuous human occupation are frequently disinfected and decontaminated with vaporized hydrogen peroxide (VHP).
  • Machines exist that actually produce the VHP.
  • VHP can also be used to eliminate all sorts of microbiological life, such as bacteria, fungus, new and common viruses, and illnesses.
  • Sometimes a H2O2 gas detector is used to ensure that a certain H2O2 gas concentration in ppm is reached to ensure efficacy when VHP disinfection.
  • Once disinfection has occurred via VHP, a H2O2 monitor is useful to confirm it is safe for people to enter the indoor space, which should be less than 1ppm.

How Does a Hydrogen Peroxide Detector Work?

Hydrogen peroxide gas detectors contain a hydrogen peroxide gas sensor that functions to identify hydrogen peroxide gas in the air.

Hydrogen peroxide gas sensors accomplish this by allowing hydrogen peroxide gas to diffuse across a permeable membrane and interact with an electrode. At this point, it becomes oxidized on the surface and generates a current proportional to the concentration of hydrogen peroxide gas present-- this is the output that the user then sees on the device.

How Long Do Hydrogen Peroxide Gas Detectors Last?

Typical gas detectors with H2O2 electrochemical sensors last from 2 to 3 years.

Who uses a Hydrogen Peroxide Gas Detector?

Many industries incorporate hydrogen peroxide gas into decontamination procedures and thus benefit from the use of a hydrogen peroxide gas detector. Examples of industries using hydrogen peroxide gas and hydrogen peroxide gas detector include:

  • Pharmaceuticals
  • Healthcare
  • Hospitality production
  • Research
  • Agriculture
  • Ventilation

Who Uses a Hydrogen Peroxide Gas Detector?

Many people in a variety of industries can find a use for a hydrogen peroxide gas detector. Most notably, those working in disinfection and fumigation protocol would find the greatest use for a hydrogen peroxide gas detector. After all, these are the individuals who will most readily be exposed to the gas.

For these people, a handheld, personal hydrogen peroxide gas detector may be most useful. This will ensure that they are not coming into contact with unsafe concentrations of hydrogen peroxide gas.

Do Individuals Need a Hydrogen Peroxide Gas Detector?

No.

The average person does not need a hydrogen peroxide gas detector. Unless working in an industry environment that readily uses hydrogen peroxide gas, the average person will not come into high enough concentrations of hydrogen peroxide gases to be harmed by it.

How Do I Choose the Right Hydrogen Peroxide Gas Detector for Me?

To select the right hydrogen peroxide gas detector, it is imperative to first consider what the device will be used for. If it is for general monitoring in an environment, a mounted device may be most useful. If it is for personal monitoring for personal safety, then a handheld or personal device would likely be best. Many times, these devices are able to clip to clothing on a person as well.

How is a Hydrogen Peroxide Gas Detector Used?

To use a hydrogen peroxide gas detector, it must first be calibrated to ensure it is ready for detection. Many times, gas detection companies will do this before the device arrives, but if not, the device can be sent to a gas detection company to perform the calibration.

When devices are on, be sure that they have enough power. If the detector runs out of power, then it will no longer accurately detect the presence of hydrogen peroxide gas in the air.

How is a Hydrogen Peroxide Gas Detector Used in Fumigation?

When performing fumigation, hydrogen peroxide gas detectors are critical for protecting staff members facilitating the process. After the room is rinsed with fresh air, a hydrogen peroxide gas detector is necessary in order to ensure that no dangerous levels of hydrogen peroxide gas remain in the room. At this point, the staff can re-enter the room safely.

How Does Disinfection Work?

Disinfection is a process of killing microorganisms using a disinfectant such as a hydrogen peroxide gas.

It contains many physical properties that make it more effective in killing bacteria, fungi, and more. Typically, it is regarded as a powerful oxidizing agent that makes it effective in the process of disinfection. Hydrogen peroxide gas is commercially available, stable, and effective for disinfecting inanimate surfaces.

How is a Hydrogen Peroxide Gas Detector Used in Disinfection?

Similar to fumigation, disinfection benefits from the use of a hydrogen peroxide gas detector to protect the people completing the disinfection process. Personal detectors may be most useful for this application of hydrogen peroxide gas detection because people are more directly interacting with the disinfection products being used.

Final Words

Gas detection is essential when working with hydrogen peroxide gas, also known as vaporized hydrogen peroxide (VHP) or H2O2. This potentially dangerous gas is acidic and highly corrosive, making it crucial to monitor its concentrations in the air.
