And mind if i ask what yer job is?

If you are having to cover the detector, and often, then yer gaffer might be as well getting a different type of detector. The way see it is if you have the facilities, you want to have it working as it should. A covered detector head may as well not be there, but you can get types that work in dusty (and potentially explosive) atmospheres

yeah, i do maintanence. Only briefly cover the sensors, and not very often at all. We have these plastic covers that you clip over them.

Last time the fridge engineer was doing some work on top of the large fridges he used an airline to blow the dust away....one little squirt on the air line and 600 people were then stood outside at the firepoints waiting for the alarm to stop.
