How intrinsically safe would our lights be?

It’s interesting that you use the word rules rather than laws. After doing some research many countries do still have these rules in place. And in some cases they are laws.
It looks like in the UK the language on the signs can vary from one station to another.
Examples include:
Switch off mobile phones
No mobile phones
Do not use mobile phones
Mobile phones must be switched off

And now because of mobile phone use for payment , some have a sign that says ,

Only use mobile apps inside your stationary vehicle.
And this variation is because technically by law the fuel stations are responsible for safety. How they manage this safety with their customers is up to them. And I found it’s quite interesting that an employee of some sort in a booth or similar needs to turn on the pump for each specific customer.
In the US and Canada the pumps are always on. You put your card in to get the payment authorized and start pumping or go in and pay in person and then the attendant engages the pump for the amount you paid for. Store employees can always switch off a pump if they see something unsafe but they’re not watching each customer pump gas. There are some exceptions such as the state of New Jersey where by law customers can’t pump their own gas so they have to have an attendant handle the nozzle. This applies to some other local municipalities also.

As for the hazardous certifications on some cell phones.
All of my five cell phones since 2012 have been made by Kyocera, a Japanese company. They’ve mostly sold phones in the North American market and Japan. Although they did sell a “torque” series in Germany and France for a few years. All the ones I have used are in their rugged category. Aimed primarily at construction and business and first responder needs. All except the last one which is the duraforce 3 have had a sapphire screen. The sapphire screen models were only available through Verizon in the US. Never a scratch on any one of them and you don’t need a screen protector of any sort. They all used a port cover for all openings. All had push to talk function. All have been fully waterproof and for the last 10 years you could take photos and videos under water and control video functions underwater with the volume buttons and an external camera button.
It is expensive to meet those certifications.
The most recent model duraforce 3 is available through Verizon. It was introduced 3 years ago. Kyocera announced over a year ago that they were not going to produce any more “consumer” phones but will still play in the business and first responder area. And as you likely figured out, those certifications that it meets do not make it intrinsically safe. Although it is safer and required for certain work environments. I did not buy them because of those certifications rather because of the other rugged features. Fully waterproof, military drop specs, scratch proof screen and more.

I also still don’t understand how non-encapsulated magnets on “intrinsically safe” flashlights is a thing..

There are special flashlights made to be “intrinsically safe” (Fenix WF05E as example). Any else are assumed as not to be such.

This requirement has a sense in some factory environments or alike.

You mean lights with mag charging ports or just potential for sparks (?) from exposed tail magnets?

I’d have thought any decent μ controller controlled charging circuit can “handshake” the charger before any current flows?

Exposed magnets for ferrous/jobsite mounting, like this one…It’s recessed, but ASSUMING that it can be dropped against something that would chip or crack it and maybe cause sparks…

Or this one, some photos showing a bare metal nut or even those exposed linkage things…I assume that environments requiring intrinsically safe tools will not have much impact work going on, so maybe that mitigates the risk of sparks…but I dunno. Maybe I’m just worrying about nothing, lol.

**Maybe there’s some super tough clearcoat or similar material that I can’t see, and the magnets are actually encapsulated to prevent abrasion and to resist impact.

Very interesting list.

Given drops possibly causing sparks being plastic makes sense, also being plastic means you can’t pump it to high lumens without it causing the light to fail prematurely. I have a 600 lumen plastic shell Coast flashlight that will self immolate if left on high for 30 minutes.

Plus, any switch either needs to be insulated out the arse or be intrinsically isolated (eg, magnetic).

Explosive vapors getting lit by sparks across the contacts can yield Unpredictable Results.

Well, one if the instructions often given if you catch your self in a thunder storm is to throw away any metallic object you hold or carry. So, what’s the point of carrying a metallic waterproof light, if you have to throw it away when a storm catches you at night, for example, when you need it?

Safety is often overlooked for the shake of “enthusiasts’” lights.

I wouldn’t feel quite comfortable leaving a lithium battery flashlight in my car during summer or use a lithium battery headlamp. And when other people are involved, like in a factory, as another fellow member mentioned above, then things are waay more serious. When we are alone, we can “play” with whatever enthusiast flashlight we like, but with other people close, that’s another kind of responsibility. I would ask twice if i’ m allowed to use my “enthousiast” flashlight and if not, i would use any plastic, simple, 30 lumens flashlight that’s safe and does the job.

So it sounds like you are suggesting that nobody should carry metal flashlights or keys or knives or anything metal because they might get caught in a lightning storm outside. And even indoors you are suggesting that people should only use intrinsically safe flashlights and ask their boss or coworkers whether it’s okay to use any electronic device that is not certified as intrinsically safe? Would you include a cell phone in that category? Or we should not even ask, we just should not ever use any electronic device that is not intrinsically safe?
Or is it mostly the lithium ion batteries that scare you? Can anybody here point to a problem caused by a lithium ion battery in a flashlight in a car?

It would lose capacity quickly due to summer heat, but that is not a safety issue, its just annoying as hell.

I was reminded of this thread last night…

For various reasons, I had to provide lighting for filling some plastic containers with diesel…

Wurkkos HD10 was the light I had on me at the time, no firey death was encountered, thankfully.

Isn’t diesel one of the safer fuels when it comes to combustability? It needs to be vaporized or heated up significantly to ignite, no?

2 Thanks

Yeah you could light this with a torch and you would be fine

Correct, from my understanding, still… ambient temps of c.22C, I could see shadow of the vapours from the light.

Let’s clarify this. But don’t try any of this at home. If you’ve ever looked into a diesel fuel tank or can that just very recently had fuel added to it you will see a mist in the tank. What you were seeing was a diesel mist not vapors. As the fuel is shooting out of the nozzle and splashing off the bottom or off other fuel that’s already in the tank it’s creating an aerated mist of very very tiny diesel droplets. And the mist is coming out because fuel is going in and filling that airspace. So you could have lit that scene with an open flame but you would NOT want to get that open flame into the mist. The mist will stop coming out as soon as you stop filling the tank. But the mist will stay in the tank for some time.
Diesel fuel isn’t really going to create vapors until you get the fuel temperature up to 52 C. So an open container of “cooler” diesel fuel that hasn’t recently been stirred up or aerated could have an open flame passed over the open cap without a problem as long as the fuel temperature is below 52 C. And if the mist is not actively being pushed up and out you could still pass an open flame over the top without a problem as long as you don’t put the flame down into the open cap. And there is no good reason to put a flashlight on high or turbo down into the mist in a recently filled diesel tank.
