It will be difficult for this thread to be added to without offending someone somewhere and I wish to say from the outset I in no way wish to offend anyone anywhere. !
This issue is one of very many human behaviour issues that affect the pre-response time to becoming aware of, and therefore taking action to escape from, a fire; whether the cue comes from the activation of a fire alarm, or from seeing, or smelling smoke, or seeing, or feeling flame.
Religious belief is only one factor. It can be a strong one and it can be imposed on people counter intuitively by people without a grasp of the situation and with perhaps more fundamental beliefs than the escaping person.
http://news.bbc.co.uk/1/hi/1874471.stmFire is a cultural phenomenon. In Western Culture we have become sanitised from its effects in very many ways. We teach our children subliminally that fire is safe and may be played with from a very early age. We show sanitised images of unrealistic fires in our media. In other cultures fire is considered to be a method of everyday cooking, a religious icon and even a cleanser.
So would a Muslim not leave prayers for a fire alarm? Possibly not. But nor probably would a Catholic or a Jew or a Presbyterian, or a Rastafarian, etc etc
No offense .... to anyone
