Explosion-Proof Mobile Phone in Cilacap Refinery

Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.

There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.

It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.

Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.

Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.

The complex processes crude into gasoline, diesel, kerosene, aviation fuel and LPG, plus asphalt and petrochemicals. Flammable vapour from light products and pressurised LPG are the usual concerns, but the plant defines its zones, so ask for the current classification.

With more than 85,000 maintainable assets and an ongoing safety-critical-element review, the refinery is formalising what is classified and how it is maintained. That usually means device approvals and area classification records are checked closely, so bring documentation.

The climate is hot and humid with a heavy rainy season, so devices on tank farms and jetties meet rain often. Check sealing and charging arrangements. Rain protection is separate from explosion protection, so confirm the permitted device list with the operator.
