Another way of looking at this, on Legal and Moral grounds.
Assuming you have carried out a fire risk assessment on this 40 bedroom hotel, you look at the doors and there are not any smoke seals anywhere.
You talk about this to the owner who explains hes not got enough money to do the work, because he's had to spend all his money of refiltting the kitchen etc.
After some sole searching you deside not to reccomend smoke seals.
Six months later a fire happens on the middle floor in room 25 at 1.15am, Mr Bigs staying and has gone out for the evening and left his laptop on charge, it bursts into flames because of a battery fault and because it was left on the bed it was soon a very big fire, and because you did not spot that the detector was a 90 degree heat detector the fire is massive before the fire alarm activates.
Before long the room is engulfed in flames and at around the time the 90 degree detector goes off the door fails and smoke is now puthering out in to the hall way, this is rapidly spreading through the hallway. People are evacuating, some are hesitating "it must be a faulse alarm they think" Mrs Smith on the top floor is sound a sleep after her sweet sherry in the bar earlyer and had removed her earing aid along with her false teeth, so does not hea the sounder thats out on the landing. Mr & Mrs Johnson on their honeymoon are dead to the world after spending all evening pub and clubing, those vodka redbulls were going down a treat.
After 9 mins the fire & rescue services attend and find a large group outside, flames are now bursting out the first floor windows and smoke has completely filled the upper floor.
Unfortunately Mrs Smith & Mr & Mrs Johnson never woke up, the drink ensured they were sound asleep and then they peacefully died of smoke inhiliation.
Six months later its your big day, you arrive at court and sat their waiting are Mr & Mrs Johnsons parents along side their three year old sobbing child who was staying at Gran's while mummy & daddy had a honeymoon, Gran points you out as the man who could have made a difference to the out come, Mrs Smiths son is there and hes mad as a box of frogs he is being help back by his wife, he just wants to beat you to a pulp.
In court you sit though the porceedings and all the expert witnessess saying how they all had smoke in their lungs and the fact that the fire never actually got to the top floor. Jack Smith the smoke seal manufacturer brings in videos and documents all about smoke seals the jury see just how good his seals are and that they may have helped save Mrs Smith & the Johnsons. Jack then drops his bomb shell, "the hotel owner even asked for a quote, but said that they were to expensive".
Its now your turn and the best prosicutor in the uk on fire safety ask's you this question. " As the expert advising the hotel owner, why did you not insist on smoke seals in your assessment".
You look around the court and see the shattered look from the Johnsons child and answer " because the hotel owner said he could not afford them"
