In hazardous environments, such as at chemical plants or in the oil & gas industry, it is crucial to connect workers using purpose-built and certified devices. These must be classified according to ATEX, IECEX, NEC500 or local specifications, EX in short. 

IS440.1, by i.safe MOBILE and sold by Exloc in US, is certified for ATEX and IECEx Zone 1/21, with NEC500 and INMETRO work-in-progress. This model can be safely used in hazardous areas (ATEX Zone 1) or further away (ATEX Zone 2) where flammable atmosphere is not likely but could occur for a short time. The ATEX and IECEx certified 5G PTT handheld ensures secure and failure-free PoC communication via public or campus networks (4.9G or 5G) or Wi-Fi in Ex-Zone 1/21. A gateway makes the IS440.1 interoperable with previous radio technologies and enables a seamless integration into existing systems.
