Explosion-proof hand chain hoists are specifically designed to be used in environments where there is a risk of explosion due to the presence of flammable gases, vapors, liquids, or combustible dust. They are commonly used in industries such as:

Oil and gas: In refineries, drilling rigs, petrochemical plants, and other facilities where flammable gases and liquids are present.

Chemical manufacturing: Where there's a risk of explosion from volatile chemicals.

Pharmaceutical industry: Particularly in areas where there's a potential for flammable solvents or powders.

Mining: Underground mines often have an atmosphere that's prone to explosions due to the presence of flammable gases or dust.

Food processing: Certain areas of food processing plants may require explosion-proof equipment, especially if there's a risk of flammable materials being present.

Paint and coatings industry: Where flammable solvents are used in the manufacturing process.

Aerospace industry: Especially in areas where there's a risk of fuel vapors being present.

Manufacturing plants: Any manufacturing facility where combustible materials are handled or processed may require explosion-proof equipment.

In these environments, using standard equipment could pose a significant risk of ignition and subsequent explosion. Explosion-proof hand chain hoists are designed with features such as sealed enclosures, spark-resistant components, and protective measures to prevent ignition in hazardous atmospheres.
