Ageing gas heaters in homes are at risk of emitting deadly amounts of carbon
monoxide (CO). Although rare, accidents do happen such as the recent Pennsylvania
case when five individuals died after sleeping in the same room as an
improperly ventilated propane heater. The cabin filled up overnight with carbon
monoxide and there were no survivors.
Gas testing is an important aspect of heating equipment maintenance and
should be executed using safe procedures. Workers installing or servicing gas
heaters need to use the best CO sensors available to ensure they are able to spot
and deal with potential issues, preventing such tragic incidents.
Carbon monoxide sensors deliver reliable and accurate CO readings,
ensuring corrective action can be taken immediately. According to the Department
of Environment, the natural concentration of CO is around 0.2 parts per million
(ppm); higher levels can cause vital organs such as the heart and brain to be
starved of oxygen leading to failure.
With a measuring range of 0 to 2000 ppm, testo 315-1 CO warning meters
feature three alarm thresholds that can be reduced or increased depending on
the situation. When testing a gas heater, workers will be able to hear and see if
the thresholds are exceeded, with the state-of-the-art alarm system emitting
both a loud audible alarm as well as a visual alarm displayed on the device’s
Following the testing of a gas heater, the building or homeowner can be
provided documentation using a testo printer, confirming that the appliance was
tested to standard.
