Protective coveralls and suits prevent the spread of contaminants and protect workers from workplace hazards. Reusable general purpose and work coveralls are worn over regular clothing to provide a barrier against dirt, dust and liquid splash. They also keep workers warm in colder temperatures. Cleanroom coveralls reduce the buildup of ESD (electrostatic discharge) and help keep cleanrooms sterile. Heat- and fire-resistant coveralls and approach suits protect workers in ambient temperatures up to 200 degrees Fahrenheit. The aluminized fabrics of the suits allow close fire proximity and do not ignite or melt.
