- Category: Hazardous Locations
Oil & Gas
Heating the various buildings associated with oil and gas transmission and processing facilities. Typical buildings that require explosion-proof heating are: compressor buildings, pumping buildings, water separator buildings, fresh water knock out buildings, produced water disposal buildings, analyzer buildings, pressure reducing stations, oil tank farms, gas & oil production satellites, well head enclosures, and drilling rigs (dog house, manifold buildings and other enclosed areas).
Printing & Packaging
Heating storage facilities for the various inks and volatile solvents associated with the printing and packaging industries. Manufacturers of cans, boxes, cartons and other containers that require printing services may use hazardous materials in the printing and labeling processes.
Heating areas where ammunition manufacturing or storage takes place.
Wastewater Treatment Plants
Heating process areas at sewage treatment plants where the potential for build-up of explosive concentration of methane or sour gas exists.
Distilleries & Breweries
Heating areas exposed to, or with the potential for exposure to, alcohol vapor in explosive concentrations.
Transport Equipment - Wash Bays
Heating wash bays used for the cleaning of tanker trucks or railcars that transport hazardous chemicals, gasoline, etc. Tanks are cleaned or purged after transport to avoid contamination of products that are not compatible with previously transported materials. Large volumes of vapor may be produced when tanks are purged. Heating equipment may need to be of explosion-proof design.
Heating medical gas storage buildings, where oxygen and flammable gases are present.
Chemical Hazardous Wastes
Heating storage lockers and containment buildings used to store chemicals, paints and other hazardous wastes.
Fuel Storage & Refuelling Facilities
Heating areas that use extremely volatile fuels, such as airplane hangers, jet fuel storage / metering facilities, natural gas refueling stations (e.g., city buses), etc.
Heating areas where fiberglass products are produced or cured after production. Factories that produce truck toppers, canoes, body panels for cars and snowmobiles or other fiberglass products may require explosion-proof heating. The fiberglass industry uses volatile solvents in its manufacturing process.
Heating areas that may contain explosive concentrations of vapors associated with various painting processes.
Heating areas where explosive concentrations of dusts may be present. These include grain handling facilities, feed mills, etc.
Heating conveyer areas at coal handling facilities, as found in coal mines, coal fired power generation plants, or any other areas where large quantities of coal are handled or consumed.
Heating chiller rooms where large quantities of fluorocarbon refrigerants are present. Freon gas decompresses to form phosgene gas when it comes in contact with surfaces with temperatures exceeding 1094ºF (590ºC). Phosgene gas is a toxic substance. Standard type heaters have elements with surface temperatures exceeding 1094ºF (590ºC). The XL4 series heaters have no surfaces exceeding 1094ºF (590ºC). The City of Chicago recently purchased heaters for this application.
