Do e-cigs produce a spark?

[lorikay13]

A simple tech question....since I want to be able to vape while in the hospital as well as have my husband be able to vape....is there any possibility that an e-cig could produce a spark that would ignite compressed oxygen??? (yes...we do plan on being stealthy...no sense creating a problem.....but hell no we are not going to go outside and stand with the analogs!)

BTW....the business cards from Mark with the little explanation on the back.........DUDE....excellent!!!! Thank you! I was going to print out my own but these are so much nicer. Thanks again!

Good question, you wouldn't want to set Ox off, but however... although these devices are electric (electronic) the power source is only approx 3.7 volts and little change of spark production, even at a dead short. Static would be a worse problem. Having said that and the risk involved i.e. hospital... perhaps just duck into the rest room and grab a vape. I'm not a product expert by no means, but a background in electronics, I'd err on the side of caution... we wouldn't want to read about that in the news and have a bad pub made on e-cigs.

I can't see the PV being anymore dangerous as using a cell phone or electronic games. Even so, until someone who knows what they are talking about says it okay, I'd refrain.

Not to be nosy...

Question: Will you be ON oxygen or a heart monitor?

I'm afraid I have to entirely disagree with your assessment, Davo.

There is an unshielded switch, both on the auto and manual batteries.

The switch contact _will_ spark with each draw and each draw release as the poles make contact.

I doubt it's likely there is enough heat contained in the spark to ignite O₂ unless the concentrations were exactly [unfortunately] right, however, the "correct" answer is that this is NOT a medical grade device, and is not properly insulated for use in an O₂ saturated environment.

Whether you want to take a risk given that parameter is your call. I suspect a blown bearing on your oxygen cart creating a hotter spark from metal-on-metal is probably more of a risk, but _I wouldn't make that call_.

I thought about this the other day while fuleing up my car...as the sign on the pump reads "DO NOT USE CELLPHONES AT PUMP" and wondered "what is going on insid an e-cig.

Any electronic device can potentially spark. If you're in an environment where any electronic device is dangerous, then I wouldn't use a vaporizer.

[Adrenalynn]

In theory - yes. However - devices designed and certified for IP*x environments are properly insulated against exposing that spark though. When we were installing cameras in a cereal production facility, we even had to use aluminum conduit. If someone nails aluminum conduit with a forklift - it won't spark like EMT or Rigid/Steel. All of our cameras had to be IP67x (the "x" is for explosive environment. The first number specifies the ability of personal to come in contact with the circuit, the second number is its water and air-borne particle resistance.)


The whole thing with cell phones and gas fueling is actually pretty dumb, but that's a whole 'nudder topic related to vapor density.

Oxygen + Energy source (spark/flame) + Fuel needed to start fire... The higher concentration of Oxygen, the better the chance of something igniting.

[Adrenalynn]

Oxygen is the oxidant, whatever is burning is the fuel. The spark or flame needs to be hot enough and of sufficient duration to cause the ignition. Diffuse reactions (ie. fuel/air) are even more energetic.
