The safety implications are relevant for anyone with olfactory dysfunction, and protection for this population group is crucial.

The cost of gas detectors can range anywhere from 20 GBP to 5000 GBP depending on the specifications. There is a need for greater recognition of these safety risks, and education about the possible solutions, including making standardised, low-cost gas detectors widely available.
