Safety Tips and Components For using Hair Dryers


The hair dryers are the handy appliance that can be used for many diverse heating applications in textiles activities. Hair dryers are used as a healing tool, to dry tint on textile fabrics or to heat or unstiffen materials used in the beautification of outfits.

Components of Hair Dryers

Heating Element:

A metal coil placed on a non-conductive material that is used as a heating element in a hair dryer. The type of resistor is called a wire resistor and consists of two parts. One is a cylindrical core, typically made of ceramic, fiberglass, or plastic, and the other is high strength metal wire. The main principle of the operation of this element is to convert electrical energy into thermal energy so that the air supplied by the fan is heated.

Therefore, the heating element should be a material with a high electrical resistivity to achieve more heat and high melting temperature (Tm) to avoid melting the material at the operating temperature which is around 40⁰C. When the temperature reaches a certain value, a safety cut off switch prevents the temperature going any further.

Regarding this, the maximum service temperature of the material can be defined as 60⁰C (max).  Furthermore, resistance to oxidation at elevated temperatures can be considered a preferred property of the material. In addition to this, the processability of the material is taken into consideration regarding the hardness of the material.

Fan of the Hair dryers:

The fan works as a transformation mechanism that converts the hot air from outside the hair dryer into hair. The mechanical energy of the motor passes through the fans that are connected to the motor. This mechanism helps the fans to rotate on their axis.

Due to this rotational movement, the air from the fan circulates over the heating element and expels the heat from the coil out through the damp hair. Therefore, material which is rummage-sale to form the fan should be able to position against high temperatures and be light-weight for easy use.


The outer casing of the appliance houses and protects the dryer fan, motor, and heating element. It is generally formed in L-shaped and its controller switches are placed on the hand-held portion in order to adjust the system easily with hand while using the hair dryers. Being waterproof is very important to the case because if a hair dryer falls into a bathtub or sink and comes into contact with water.

It would make a short circuit and lead an electrical shock.  Additionally, the weight of the housing is extremely vital in terms of being easy to handle during operation. Therefore, small density (ρ), little thermal conductivity (λ), and being waterproof and rust-resistant are primary standards for housing. The main material qualifications explained above are summarized.

Identified Risks and Hazards

General hazards that may ascend when by means of an electric heating appliance include:

  • scalds from hot metal or components
  • gasp of harmful emission
  • overheating can harm work

Universal hazards that may arise after using hair dryer in a textile’s environment include:

  • Burns from hot materials or metal components of the dryer
  • Inhalation of hot plastic and paint fumes
  • Electric shock if the power cord is damaged
  • Surfaces can be damaged by excessive heat from the dryer

Pre-operational Safety

Before using the warm glue gun, examine the power cord if they are workable, extension lead, plugs, sockets, and power outlet are working fine. Look for:

  • split or damaged covering
  • plain wires or loose network cables
  • harm to cord casing
  • loose or missing bolts
  • Make sure that there are no flammable gases, liquids or other materials in the work premises.
  • Make sure the switch of the hair dryer is off when you connect it to the network.
  • Do not use the hair dryer in narrowed spaces, or where the ventilation is measured not to be adequate.

Operating Safety Precautions

  • Ensure the dryer you have tested and labeled before you use it.
  • The dryer must be carried or placed near any type of liquid.
  • Never touch metal parts of the dryer due to hot which could burn or damage your skin.
  • Avoid placing nearby flammable materials or gases.
  • Don’t put unattended while running the dryer.
  • Don’t put on highly flammable objects.
  • Don’t use always on high temperatures which may cause harm to other materials.
  • Avoid wearing loose-fitting clothing or costume jewelry.
  • Wear proper plastic footwear and a caring hair casing to contain long hair.
  • Never carry the dryer along with the power cord or pull the cord from an electrical outlet.
  • Always turned off or disconnect the dryer when you are not using it.
  • Avoid unintended starting.
  • If the dryer stops during operating, turned it off from the power supply or socket, and inform your supervisor.
  • If not in use the dryer should be placed in a safer location and switched off.
  • Avoiding winding the cord around the build of the dryer while it is still warm.
  • Before changing accessories, always turned it off and make it sure the nozzle must be in a cool place.
  • Don’t touch the hair dryers if your hands are excessively wet.
