Here's why mechs are safer than a regulated. First and foremost, a mech forces you to teach yourself ohms law and do your homework on battery safety. The prime reason why accidents happen with Lithium rechargeable batteries is a blatant lack of knowledge in this regard. Secondly, when the battery in a tube mech heats up, typically so will the metal body of the mod... whereas most regulated devices have overheat protection built in, but this is to protect the board from overheating, NOT the batteries so these devices typically don't show the battery temperature on their main screen, and you typically can't feel the batteries starting to overheat until they are dangerously close to starting to vent. By the time the battery will have reached those kinds of very high temperatures, the outside of my brass tube mech will be so burning hot it will be simply impossible for me to still vape on it. What's the risk of me causing a direct hard short on the battery in my solidly built mech mod vs. the risk of a cheap made in China built-in electronic protection circuit failing to do what it's been designed to do? Have you seen what the inside of the battery compartment in most regulated devices looks like? What are the chances of a direct hard short happening inside of one of those things compared to it happening inside of my Purge Mods? Do you even know what the design/construction of a Purge Mods looks like? Most people using a regulated don't even understand the difference between a battery venting and a battery going into thermal runaway, let alone understand what's needed to cause a battery to go into thermal runaway. So... now you know why I don't take most people serious when it comes to preachings about safety.
Before I tear into this statement (not you... this isn't personal), I want to go on record as saying that I DO think mechs can be safe when used as intended by someone educated and experienced...
The problem with your statement begins very early on...
Owning a mech forces no one to do anything. John or Jane D'oh can walk into a vape shop, drop $50 on a clone mech with hybrid cap, a cheap cell, and subtank and blow themselves up. Heck... they can spend even less and get a seriously inferior cell for less online... my first was a K101 that came with Kamry branded cells. I was quite lucky as I did try those cells for a while and never has an accident, but luck was all it was...
Learning the ins and outs of mech mods, maintenance, ohms law isn't a given... it requires work.
Knowing ohms law and proper mech care still does not make the DEVICE safer. It only makes the operator safer.
Perhaps you're not going to experience a hard short in your $250 purge mod due to its sleeved construction (similar sleeves also available in the Broadside and Black Ring 1 & 2), but the average new vaper isn't going to grab that... they're gonna buy that kit they see in the local B&M, or the kit they see on eBay or FastTech.
This is the first link in a quick Google search for mech mod:

The plastic tray inside a cheap regulated will offer a lot more protection agains accidental short than any unlined metal tube.
A tube heats up as the battery stresses, sure. And, an educated, experienced vaper should know that if a tube is getting too warm, something is amiss, and it's time to check the battery or the build, or maybe take a break and let things cool off. However, an inexperienced vaper might not kniw at what level that point comes and take just one too many pulls. A board... which is awful close to the batteries... will shut down and prevent that behavior.
Again, I know and agree that in the hands of an educated, experienced vaper a quality mech mod can be quite safe. But, making blanket claims that mechs are safer without any qualifications is incorrect.
