Additional safety instructions and warnings

To minimize the risk of re in a tumble dryer, the following should be observed:
• Items that have been spotted or soaked with vegetable or cooking oil
constitute a fire hazard and should not be placed in a tumble dryer.
• Oil-affected items can ignite spontaneously, especially when exposed to
heat sources such as in a tumble dryer. The items become warm, causing
an oxidation reaction in the oil. Oxidation creates heat. If the heat cannot
escape, the items can become hot enough to catch fire. Piling, stacking or
storing oilaffected items can prevent heat from escaping and so create a
fire hazard.
If it is unavoidable that fabrics that contain vegetable or cooking oil or have
been contaminated by hair care products be placed in a tumble dryer they
should first be washed in hot water with extra detergent - this will reduce,
but not eliminate, the hazard. The ’cool down’ cycle of tumble dryers
should be used to reduce the temperature of the items. They should not be
removed from the tumble dryer or piled or stacked while hot.
• Items that have been previously cleaned in, washed in, soaked in or
spotted with petrol/gasoline, dry-cleaning solvents or other flammable or
explosive substances should not be placed in a tumble dryer.
Highly flammable substances commonly used in domestic environments
include acetone, denatured alcohol, petrol/gasoline, kerosene, spot
removers (some brands), turpentine, waxes and wax removers.
• Items containing foam rubber (also known as latex foam) or similarly
textured rubber. like materials should not be dried in a tumble dryer on a
heat setting.
Foam rubber materials can, when heated, produce fire by spontaneous
combustion.
• Fabric softeners or similar products should not be used in a tumble dryer
to eliminate the effects of static electricity unless this practice is
specifically recommended by the manufacturer of the fabric softener or
product.
• Undergarments that contain metal reinforcements should not be placed in a
tumble dryer.
Damage to the tumble dryer can result if metal reinforcements come loose
during drying. When available a drying rack could be used for such items.
• Plastic articles such as shower caps or babies’ waterproof napkin covers
should not be placed in a tumble dryer.
• Rubber-backed articles, clothes fitted with foam rubber pads, pillows,
galoshes and rubber-coated tennis shoes should not be placed in a tumble
dryer.
