Industrial telecommunication devices for high-risk work environments are a specialized type of communication device designed to be used in areas where the presence of explosive substances or ignitable fibers poses a significant risk of electrical sparks.

The risk factors associated with these environments are so great that standard phones would be a serious explosion hazard if used in these areas.

To address this issue, the IEC has developed a series of guidelines (IEC 60079) for electronic devices used in hazardous areas.

In order to be used in hazardous areas, industrial telephones must meet the requirements of one of two groups of standards: Zone 1 and Zone 2 areas, or Division 1 and Division 2 areas. Zone 1 and Division 1 areas are those where the probability of a hazardous atmosphere being present is high, often due to routine operations. Zone 2 and Division 2 areas are those where the threat of hazardous atmospheres is lower, typically due to abnormal events.

Industrial telephones for hazardous areas must be designed and constructed with safety features to prevent electrical sparks from occurring. This includes the use of flameproof or explosion-Vandal proof Jail Telephone enclosures, intrinsically safe components, or detonate-resistant connections. The phones must also be able to withstand vibrations and extreme temperatures, ensuring continuous operation in harsh environments.

In addition to the IEC regulations, local and national regulations such as the Explosives Act and the Hazardous Areas Directive must be adhered to when selecting and installing industrial telephones in hazardous areas. The selection of the correct telephone is crucial, and it is essential to ensure that the device has been certified by a recognized third-party inspection organization, such as the IEC or the Factory Mutual Research Corporation.

When selecting an industrial telephone for hazardous areas, the end-user must consider several factors, including the category of area, the operating environment, and the level of protection required. Additional factors that must be considered are the security aspects of the telephone, its ergonomics and ease of use, and its compatibility with local regulations and standards.

In conclusion, industrial telephones for hazardous areas are critical in ensuring safe communication and emergency response in potentially hazardous environments. The selection and installation of these devices are governed by strict standards and laws, and wrong decisions can result in severe consequences. With careful consideration of the requirements and by selecting certified equipment, organizations can ensure a reliable and safe means of communication for their personnel and assets in hazardous areas.
