Coil temp

My conclusion would be that your setup did as it was supposed to. When around explosive gasses, you also want to account for gear that has a potential for doing something else than it's supposed to. Like arc. Or run dry. Or... or...

ohhh and BTW, the cap was off and no wicks... just pure hot glowing coils immersed in a gas/air mix

Knock it off.

Okay I understand vaping in the yard with LNG fuelling station would be a little sketchy. What I don't get is vaping in a truck with LNG. All trucks are equips with sensors if there is a leak. ( red light / green light) on the dash. They have also banned it on all diesel trucks. I know my work can ban whatever they want, I just thought this was a poor excuse to ban vaping. Sorry if I came across as some kind of righteous ahole, can vape wherever I want, I'm not like that. Just wanted some information.... Thanks bunnykiller

I didn't mean to offend, though I often do without meaning to. I still need to work on that.

I can agree, in the truck, with sensors to help detect leaks even your nose can't, the risk is astronomically small. I also agree that the blanket ban -in all areas- is truly failtastic.

My only gripe was with the situation in the yard, where gas and air can be mixing without people knowing it. I've felt first hand the damage even a brief flash blast can do - my left arm was blistered from shoulder to wrist in a propane flash while I was trying to light a forge once. That wasn't even an explosion, just a flash flame. It seemed to me (I may be mistaken) that you asked a pretty straightforward question, and then argued with people's answer. Thus, my asshattery.

Yeah, I would think proper reasoning should be brought to bear about areas where gas is not of true concern, and bringing some reason to the boss folk might be in order.

My thinking is just that I have on more than one occasion 'sacrificed' one of my gennie setups for use as an emergency lighter. It's just a question of sufficiently drying out the wick. Take away the wick, and you take away one way an atty can fail - drying out and setting the wick on fire. Not likely under normal use. Still a possibility that has to be accounted for when deciding if it's OK for use in potentially explosive environments.

We may have different perspectives on the entire scenario. I'm picturing a leaky gas truck in an enclosed area/garage. Which I must admit is not an extremely likely repeat scenario.

Here's some tests I did at work a while back.

Used a thermal camera on my dripper. This is a saturated wick.

Here's the temps you can expect dry burning kanthal. No wick, glowing red to burn off crud.

If they ban cell phones and other electronics, that would be a greater basis. Or cooking anywhere on the premises. It definitely doesn't spew cinders unpredictably. They shouldn't be used entirely casually in that environment.

When it comes to safety, a company has to err on the side of caution.

It so happens there was a gas explosion just about 2 weeks ago about a mile from my house where 3 fast food places blew up; 10 plus people injured;
Update on El Pecos explosion - Trinidad & Tobago Online

I used to get food from that area a lot.


The fact that a coil gets red hot when dryburning is enough for me to be concerned in a situation where large amounts of gas fuel is present.

for your average cigalike that's properly wicking the coil
temp. of about 194 degrees F is sufficient for vapor production.
as one uses more advanced gear coil temp.'s tend to go higher
to produce faster vapor production thus more vapor.
somewhere one will reach the point where the water in
the juice is insufficient to maintain the proper atomizing
of the base liquid. things go down hill from there.

Coil temperature is not really important in your case. Important thing is that sparks may (and will) be generated when your press "On" switch, they will be generated outside your atti. How dangerous is it - it is up to your company to consider.

If these vehicles are leaking enough gas to cause an explosion e-cigs are the least of their worries.

No ecigs near the filling station, sure OK. But after that the vehicles are either safe or not, if not fix em and no worries about ignition sources.

 

[DoubleTap1]

Even flashlights at the company I work for have to be explosion proof lights, and there is no smoking or vaping anywhere on company grounds.

Safety rules are largely driven by the question of liability, which in the context of a natural gas installation requires one to remove foreseeable risks. Thus, the question isn't can one safely vape around natural gas, but rather can a person unsafely use an e-cigeratte around natural gas. The answer to that question is yes. All it takes is a dry wick in an e-cigeratte and someone inadvertently pressing the fire button too long. In addition, the e-cigeratte industry is pretty much unregulated. This means these devices do not go through the same level of consumer safety testing as cell phones or many other electronics. Consequently, there's no way for a natural gas installation to have any confidence that potential fire and electrical risks associated with a particular e-cigeratte design is sufficiently low enough to allow their use.

I just need to reply to the general idea that since the rule in complaint cannot be proven, do you still want to be the lucky guy that proves it?


I see plenty of people saying the right thing in this thread in the idea of liability.

 

[Woofer]

I have a natural gas boiler, stove, oven and dryer. I vape in the house I even vape in the boiler room.. gasp
I have smoked in natural gas and propane powered vehicles.

Again... not vaping around the filling area is sensible. Once the tank is full it better not leak or they face a world full of liability.
It is an ignorant restriction.
