Zone 2 areas and Zone 1 pockets
Because Zone 1 equipment may be used in Zone 2, the handset can cover a whole terminal. The IS-04Z1 is designed for Zone 1 and Zone 21, with the marking target II 2 G Ex ib IIC T4.

Explosion proof mobile phone for Gas, LNG and Regasification in Spain
Spain has more LNG import terminals than any other European country, and the gas network behind them runs through compression stations, storage fields and regulating sites. This page is for the HSE, operations and telecoms staff who need an explosion proof mobile phone in Spain that works across terminals, jetties and pipeline stations. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

The sector · Gas and LNG
Where gas and LNG are classified in Spain
The Spanish gas sector is built around coastal regasification terminals: Barcelona, Cartagena and Huelva on the Mediterranean and Atlantic coasts, Gijón El Musel in Asturias, Bilbao in the Bizkaia estuary, Sagunto near Valencia and Mugardos in Galicia. Between them they receive LNG from ships, store it in cryogenic tanks, vaporise it and send it into the grid, and several also load LNG into road tankers. Beyond the terminals sit compression stations, regulating and metering sites, and underground storage at Serrablo, Yela and the Gaviota offshore field. The dominant gas is methane, group IIA, which is harder to ignite than hydrogen or ethylene, so many open-air areas are Zone 2, with Zone 1 around vents, sampling points and some pump and compressor areas. A device suitable for Zone 1 is also suitable for Zone 2, which is why operators often issue one handset across the whole plant.

Built for local conditions
What an LNG terminal does to a handset
Terminals are bright, open and well ventilated, which makes them look benign, but the work includes cold, wet and exposed conditions. Four points come up in practice.
IP ratingIP68
Battery4,000 mAh
Camera50 MP
OSAndroid 16
Ship discharge to a timetable
A carrier arrives on schedule and the jetty, tank area and control room are in contact throughout. A single device with a camera and a call link removes the swap at each boundary.
Wind, spray and cold
Terminals are exposed coastal sites. IP68 sealing is aimed at spray and rain, and the certificate will state the ambient range for the cold end of the day.
Odorant, nitrogen and sampling lines
Sampling points, odorant injection and nitrogen systems each carry their own considerations beyond methane, and they are usually where a technician is closest to a release point. The temperature class and gas group on the certificate are what an instrumentation engineer checks for those locations, and the figures will be on the datasheet.
Lone workers on remote stations
Pipeline stations are visited alone, far from help. Four-constellation GNSS puts a position on the visit record and 4G keeps a call link up where coverage exists.
Use cases · Gas and LNG
Where the IS-04Z1 goes to work in Spanish gas.
Terminals01
Ship unloading rounds
An operator walks the berth, the arms and the tank area while a carrier discharges. Readings, photographs and a call to the control room come from one device carried inside the boundary.
Pipeline02
Station inspection
A technician driving between compression and metering stations needs drawings, a camera and a record of the visit. A managed handset keeps all three on one device.
Contractors03
Tank and vaporiser inspection
Inspection firms working inside the terminal use the handset for photographs against equipment tags. Policy set in the console limits the applications available during the job.
Questions · Gas and LNG
Explosion proof mobile phone questions for Spain
How many LNG terminals does Spain have?
Spain has six regasification terminals in active use plus the El Musel plant at Gijón, which Enagás owns. The exact number in service can change, so check the current position with the operators.
Does the IS-04Z1 work on a jetty?
It is designed for Zone 1 and Zone 21 and has IP68 sealing, so spray is not a concern. Marine use specifically has not been certified, and any jetty trial needs approval from the terminal operator.
Is methane a group IIC gas?
No. Methane is group IIA. The IS-04Z1 target marking is IIC, which covers more demanding gases such as hydrogen, so a methane-only site is within range.
Where can I read about specific operators?
See our page on an explosion proof phone for Enagás, which covers the largest terminal operator and the transmission network. The Tarragona, Cartagena and Huelva areas that sit beside these terminals are covered under refining and petrochemicals.
Enquiry · Gas, LNG and Regasification
Ask about the IS-04Z1 for Gas, LNG and Regasification, Spain
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 Spain. 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.
