what sort of gas laws? do you mean stu like havent to be corgi registered 'cos if you do mean that i can ort of answer it. if someone instaled a gas apliance and they did it wrong the gas could leak and it poison you befor you realise but if it smething say electrical then it might start off as a small fire you can put out or escape from. i think that answers part of your question if not i'll try and answer it aain if you ment difrent laws.
p.s. sory my writings not very good im in a rush and typing quikly.
Or do you mean the Gas Laws which define the relationships between temperature, volume and pressure. (Boyles Law, pressure:volume; Charles�s Law, volume:temperature; and Gay Lussac�s law, temperature:pressure)?
