Explosion proof mobile phone for Versalis in Italy: this page is for the safety, maintenance and procurement teams at Versalis, Eni’s chemicals company, whose Italian plants at Brindisi, Priolo, Ravenna and elsewhere handle monomers, polymers and elastomers. It covers what those hazards mean for a handset 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
Versalis is the chemicals arm of Eni, and its Italian sites are built around a few linked families of product: ethylene and propylene from cracking, polyethylene and styrenics made from them, and synthetic rubbers. The plants named on this site are Brindisi in Puglia, Priolo in Sicily and Ravenna in Emilia-Romagna, and the company also runs sites at Mantova and Ferrara. Press reports say the Brindisi and Priolo steam crackers have been or are being shut down as part of Eni’s restructuring of its chemicals business, so confirm what is running at each site before assuming a unit is live. What does not change is the character of a chemical complex: monomers that are heavier than air, hydrogen in the same utility corridor, and polymer or rubber powder in finishing and bagging halls. A shift covers both Zone 1 gas areas and Zone 21 dust areas inside one fence, which is why a single handset rated for both matters here.
Chemical plants differ from refineries in how often the hazard changes. A unit can be gas-hazardous on Monday and a dust hazard on Thursday, after a changeover. Four conditions matter most for a handset.
A technician at Ravenna or Mantova may check a pump in a gas area and then enter a finishing hall with polymer or rubber dust. The IS-04Z1 is designed for Zone 1 gas and Zone 21 dust under one certification programme, so the person does not swap devices at the hall door.
Light olefins and hydrogen sit at the demanding end of the gas groups. The target marking II 2 G Ex ib IIC T4 is aimed at that end, and the datasheet will carry the actual group and temperature class once the certificate is issued.
Where a cracker has been or may be closed, units are being isolated, decontaminated and sometimes repurposed. Inspection and decommissioning crews working through that need photographs, GNSS positions and a reliable call to the control room, all on a handset that is allowed to be in the area.
At Priolo, pipes, utilities and the road network are shared with neighbouring operators. A device managed from an existing console and locked to approved applications behaves the same wherever the contractor works that week.
A round through reaction, drying and finishing covers gas and dust areas in one walk. One handset records readings, photographs a leaking seal and calls the shift supervisor without a trip to a safe area.
As units are stopped, cleaned and isolated, work orders multiply. Permit status, isolation photographs and sign-offs on one managed device keep the paperwork aligned with what was physically done.
Firms resident on a chemical site hold equipment for months, not days. Enrolment, application control and remote wipe let the plant issue and recover handsets in the same way it issues keys and badges.
We cannot say. Press reports describe closure of the Brindisi and Priolo crackers as part of Eni’s chemicals restructuring, but the site operator is the authority on what is running. Ask Versalis directly before relying on any description of a unit.
The design target is gas group IIC, which includes hydrogen and covers the IIB gases such as ethylene. The certificate will state the group and temperature class, and the entry in your explosion protection document should use those figures once they exist.
Normally the ATEX and IECEx certificates, the declaration of conformity and manual in Italian, and evidence of a repair route that suits intrinsically safe equipment. Exact supplier qualification steps are set by Versalis and Eni; ask their procurement and HSE teams for current requirements.
No. The device is pre-launch for Q4 2026 and its certification is in progress. Evaluation units are offered under a trial agreement, and nothing is supplied into a classified area before the certificate exists.
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.
