How suppliers reach OGDCL
OGDCL publishes tenders and enlistment documents for suppliers and contractors on ogdcl.com; applicants must be on the active taxpayer list and may be visited for premises checks. Confirm current requirements with its procurement team. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In OGDCL. For wellheads, compression facilities and LPG recovery plants, the everyday term explosion-proof can hide two different approaches. Flameproof Ex d contains an internal explosion in a heavy enclosure. Intrinsic safety limits electrical and thermal energy so a handheld cannot ignite gas. A phone relies on the second, and the target is II 2 G Ex ib IIC T4.

Questions · OGDCL
Frequently asked questions
Can OGDCL buy the IS-04Z1 today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an explosion proof mobile phone for OGDCL cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
How does OGDCL approve suppliers?
OGDCL publishes tenders and enlistment documents for suppliers and contractors on ogdcl.com; applicants must be on the active taxpayer list and may be visited for premises checks. Confirm current requirements with its procurement team.
Is intrinsically safe the same as explosion proof?
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.
How hot does it get at OGDCL's Sindh and Punjab fields?
Fields in southern Sindh and south Punjab can see very high summer temperatures with dust, while the north-west and Potwar plateau are cooler in winter. For handheld devices check the rated operating temperature, dust ingress protection and battery behaviour in heat, and ask the site for its limits.
How do suppliers register with OGDCL?
OGDCL runs its own procurement under public-sector procurement rules, usually through tenders and vendor registration, with technical approval by the field or department concerned. Confirm the current registration and certification requirements with OGDCL's procurement office.
What do suppliers need to do to be considered by OGDCL?
OGDCL publishes tenders and enlistment documents for suppliers and contractors on its website, and applicants must be on the active taxpayer list and may be visited for premises checks. Procedures change, so confirm current requirements with its procurement team. The IS-04Z1 has no certificate yet.
