How to monitor your exposure to Ethylene Oxide


Andersen Products sterilisers are built to the highest safety standards to ensure that operators are never exposed to Ethylene Oxide (EtO), which is the gas used for sterilisation. Nonetheless, you should always check your exposure levels upon installation of your steriliser. We also recommend that you measure your exposure each time your steriliser is moved to a new location. As a general rule, it is good practice to check exposure levels once a year. You might also need to monitor your exposure if your workplace is being inspected as part of Practice standards and you need to prove that your EtO level is below the legal limit, which under UK rule is 5 parts per million (ppm) over a period of 15 minutes.

The easiest way to monitor your exposure is to use an AirScan badge from Andersen Products. An AirScan badge is a single use badge that you can wear on your clothes or leave near the steriliser so as to measure the airborne concentration of Ethylene Oxide in the room. One of the main advantages of this specific badge is that you won't have to send it to an external laboratory for analysis: you will be able to get the result of the reading directly from the device itself, using the conversion chart provided.

If you browse our catalogue, you will notice that several "AirScan" items are available (the "AN-91" which measures exposure over a period of 8 hours, the "AN-92" which measures exposure over a period of 15 minutes, the "AN-93" which is actually a kit made up of these two individual badges). Most of the time, we do recommend the "AN-92" as it will allow you to check that your exposure is below the limit set by the Health and Safety Executive (HSE) in the UK. This badge is to be worn while unloading the steriliser, which is when the greatest exposure to ethylene oxide is likely to be encountered.

This video will show you how to use the AirScan badge AN-92 to monitor your exposure to ethylene oxide.
