It is very important that a clothes dryer is used as per the manufacturers specifications, if they are not used correctly they can quickly become a fire hazard.
You 
may have seen the fire triangle in the past, the three elements you need to sustain a fire are – heat, oxygen, and fuel. As you can imagine a poorly maintained or incorrectly used clothes dryer create the perfect environment to start a fire. Any clothing or fluff that gets too hot and begins to smolder has plenty of oxygen to ignite.
Clean filter after each load
This is the number one rule of dryers, you must clean the lint filter after each load. This not only saves you money and cuts down on drying time but it prevents the machine from overheating. If your machine cuts off it is usually a sign the machine does not have good air flow, there could be a number of factors that have caused this but the first thing to check is that the lint filter is clean.
Replace torn lint filters
It is important that you replace a torn filter. Torn filters allow dust and lint to enter the machine and once this builds up it can become an extreme fire hazard.
Always, Always, Always clean the lint filter after each load of washing, this not only makes your dryer run more efficiently and dry your clothes faster it reduces the risk of a fire starting.The volume of clothes many families go through on a week by week basis is far too much to try and dry out over clothes horses and furniture. By doing some simple preventative maintenance yourself you can help keep your dryer in running order.
