Intrinsically safe torches - ATEX zone 0 or zone 1?

[NorthernLass]

Hi

Im looking to buy an instrinsically safe torch for use on deck, I have found that Peli do a nice selection of these torches but they are all categorised into zone 0 or zone 1. All are ATEX classified.
Does anyone know what this means?

Thanks

Zones are classified by what amount of explosive substance could be inside them.

Zone 0 is an area in which an explosive gas atmosphere is present continuously or for long periods
Zone 1 is an area in which an explosive gas atmosphere is likely to occur in normal operation

There's a Zone 2 as well which is areas in which an explosive gas atmosphere is not likely to occur.

As zuluonezero says.

Zone 0 is likely to be the most expensive and would only be required if entering a tank full of explosive gases - somehting I dont think you'll be doing.

Zone 1 would be fine for taking out on deck and using down a gas purged tank. We use the Zone 1 Peli head torches onboard.

We use PELI torches on board, very good and reliable, I also have a one of these in my pocket all the time, very good for on the bridge at night.

Thanks very much. So ill be safe with a zone one, excellent. A few of the officers ive worked with have recommended Peli to me, so ill take their advice.
