So I'm not sure what the right community for this is but I'm hoping yall can help. I'm a refrigeration service tech and recently I was tasked with replacing a sensor in a room used to store ethanol drums. Due to the nature of the room every device in it had to be rated explosion proof and I couldn't use any tools that could pose any risk of ignition (no heat gun, basically nothing with an electric motor, and definitely no open flames) while working in there. Normally when I splice wires I use heatshrink to cover the splice simply because it looks far more professional than electrical tape and it holds up better over time. However in this case I could not figure out any way of shrinking said heatshrink without posing a potential ignition hazard so I was stuck just wrapping the splice in tape. We do a lot of work for this company so I'm hoping to find a better solution for the next time I am in a similar situation.

So do any of you know any way to shrink heatshrink without posing an ignition hazard or am I stuck just using tape in those situations?

It's very expensive, but it would probably be the best option when you can't use heat.

In this case they can pass the cost onto the customer. The higher restrictions will always result in higher costs, so they're probably used to it.
