Anti-icing chemical is a substance that is used to prevent freezing and frost formation on various surfaces. These chemicals play a very important role in industries such as aviation, automotive, and transportation infrastructure. Anti-icing agents are generally divided into two main types.
Anti-icing for aviation: These chemicals are applied as a spray or liquid on the wings and external surfaces of airplanes to prevent ice formation and increase flight safety. Aviation anti-icers are usually composed of glycol compounds (such as ethylene glycol and propylene glycol) that provide good anti-icing properties. These compounds lower the freezing temperature of water and prevent ice from sticking to metal surfaces.
Anti-icing for infrastructure and roads: Anti-icing chemicals are used for roads, bridges and other public infrastructure. These chemicals are usually composed of salts such as sodium chloride, calcium chloride and magnesium chloride. These compounds prevent the formation of ice and frost on the road surface by reducing the freezing temperature of water. At the same time, some newer materials include more environmentally friendly solutions that have less environmental impact.

Environmental impact of Anti-sludge
Some anti-icing compounds can have a negative impact on the environment. For example, chloride salts may contaminate surface and ground water and harm plants and animals. Hence, environmentally friendly anti-icing materials are being developed and used to minimize the environmental impact.
Safety Measures and Regulations for Handling Anti-Icing
When working with anti-icing materials, to maintain safety and prevent negative effects on health, it is necessary to observe the following safety tips and regulations:
Use of personal protective equipment (PPE):
Safety gloves: To avoid direct contact of antifreeze with the skin, the use of resistant gloves is recommended, as some antifreezes, especially those containing glycols or chlorides, may irritate the skin.
Protective glasses: When using antifreeze, especially in the form of spray or powder, it is necessary to use safety glasses to protect the eyes from splashes and accidental contact.
Mask or respirator: When working with liquid antifreeze, especially in confined spaces, a respirator can help reduce inhalation of harmful vapors.
