Agreed, methos stoves very safe, as long as you dont perform any Darwin acts.
Dont fill through the top - They usually have stickers saying this.
Careful dousing a metho fire with water, liquid, etc - It can just dilute & spread the fore, and the flames can be difficult to see.
Fire blanket always a cheap & effective solution - But dont hang it on the shelf behind the stove (ie: you must reach across burning metho stove to grab fire blanket).
Lessons learnt the hard way are usually those most well understood!
