You've probably all read that a couple of the members on here have recently had potentially very dangerous accidents involving their skis and surplus petrol being ignited by a spark caused by shorting the battery positive terminal to earth.Please don't forget that it is the vapours mixed with air that these flammable liquids give off that actually burn,so anywhere that there is petrol ouside of a closed container is an accident waiting to happen unless we observe all the proper safety procedures.
1.If the battery doesn't come with protective insulating covers over it's terminals,get some fitted,they cost next to nothing,but could save thousands of pounds worth of ski,and your life.
2.When you're working on the ski,always disconnect and remove the battery first until you actually need to start the engine.This only takes about five minutes or less to do,and really isn't as much of a chore to do as some people make out.
3.If you need to use jump leads to start your ski (as well as observing the proper procedure to prevent damage to any electronics that some may have),always connect the positive first at the battery terminal,and then just in case there are any sparks when you connect the negative,do this as far away from the tank as possible,i.e.the bolts at the back of the head.
4.DO NOT SMOKE ANYWHERE NEAR THE SKI WHILST WORKING ON IT.I am still amazed how many times I see people putting petrol in their skis and have a lit cigarette in their mouth at the same time,this contravenes probably about half of the health and safety regulations in the book.Next time you fill up,look from low down and notice how big the cloud of vapours is that gathers around the filler pipe,again all mixed with air.
5.As with anything involving flammable liquids,always work in a VERY well ventilated area,and be aware of all the other potentially dangerous liquids around your working area,not just petrol.
6.The best way to put a fire out is to starve it of what it needs most,and that is Oxygen.If you can get the hood back on,the flames will use up the air inside quicker that it can be replenished,and go out very quickly,or even better is a nice thick blanket.And hopefully every workshop will have a working fire extiguisher handy,and do make sure you have the right type to put out the type of fire (i.e. chemical etc) that could possibly happen.
If anyone has anything to add to this,please let me know.
