Explosion proof mobile phone for Snam in Italy: this page is for the HSE, maintenance and telecoms staff who keep Italy’s gas transmission network, underground storage and LNG regasification running. It looks at the compressor stations, storage fields and terminals where a handset has to be safe, and what the IS-04Z1 is being certified to do. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
Snam is a different kind of hazardous-area operator from a refinery. Natural gas is the only product, the network covers the whole country, and most of the plant is unmanned for most of the time. People arrive in vans to do a planned visit, an inspection or a repair. The transmission grid runs to well over 30,000 km of pipeline, fed at entry points such as Mazara del Vallo, Gela, Tarvisio, Passo Gries and the terminal at Melendugno where the Trans Adriatic Pipeline comes ashore. Along it sit compressor stations, metering and reduction stations, and the dispatching centre at San Donato Milanese. Underground storage is held by Stogit, in depleted fields such as Minerbio, Sergnano, Brugherio, Settala, Ripalta, Bordolano, Cortemaggiore, Sabbioncello and Fiume Treste. On the LNG side Snam owns Panigaglia and runs floating regasification units at Piombino and off Ravenna. The hazard is methane, gas group IIA, which is the least demanding gas group, but the surroundings are remote and variable.
A transmission operator’s technicians travel more than they walk. The handset has to work at an unattended station, on an offshore vessel and in an office, and carry data for all three.
A technician alone at a reduction station needs to call for help, share a position and record the job. Four-constellation GNSS and cellular connectivity on a Zone 1 device cover that, and a lone-worker application can be pushed from the existing console.
A van may visit six sites in a day, each with a short job in a classified area. A 4,000 mAh battery matters because there is no charge point at a metering station and a handset that flattens on the third site is useless.
Natural gas is gas group IIA, and the IS-04Z1 target is the broader IIC. Any odorised or mixed gas, or a site with hydrogen blending trials, is covered by the same marking, which spares a re-selection of equipment.
Statutory checks and pipeline integrity inspections produce photographs and readings that are audited later. The 50 MP camera and position fix put a legible image and a coordinate on the record, and Android Enterprise policy can control where and when the camera is used.
A technician arrives at a compressor station, enters a permit, checks the vent stack and photographs a gland. The handset carries the permit, the checklist and the call to the dispatching centre.
Inspection of wellheads and dehydration plant at a field such as Minerbio happens across wide pads. One managed device replaces radio, camera and paper, and shows the person’s position to the site supervisor.
Berth operations at a floating unit rely on a small crew and a tight schedule. A handset that holds the checklist, the position fix and a push-to-talk style call helps a crew reach the control room from the jetty.
The page lists the main asset types and named storage fields and terminals. Individual compressor, metering and storage sites differ, and the zone map for each is held by Snam. The handset is designed for Zone 1 and Zone 21; the specific zone at a given site is Snam’s call.
It can be. Methane is gas group IIA, hydrogen is IIC, and the IS-04Z1 is being certified to IIC, so the same device is designed to remain suitable if a station’s gas mix changes. Snam’s classification documents decide what is required.
Large utilities normally do, and Snam’s contractors work to its health and safety rules. We have no relationship with Snam. Ask its procurement and HSE teams what registration and equipment evidence they require.
The device is pre-launch for Q4 2026 and certification is in progress. Evaluation units are available under a trial agreement, and use in a classified area waits for the certificate.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Italy. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
