Explosion-Proof Mobile Phone for KazMunayGas
KazMunayGas is Kazakhstan's national oil and gas company, formed in 2002 and headquartered in Astana. KazTransGas handles gas transportation inside the group, which means compressor stations and gas pipeline sites form a separate hazardous-area workforce from the oilfield and refinery operations. If you are specifying an explosion proof mobile phone for KazMunayGas, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereKazMunayGas
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for KazMunayGas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Sites and areas
- Atyrau refinery
- Pavlodar refinery
- Shymkent refinery (50% joint venture)
Classified areas
- Refinery process units
- Oil and gas production facilities
- Pipeline stations
Supplier approval · KazMunayGas
How suppliers reach KazMunayGas
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. 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.
Field notes · KazMunayGas
More about KazMunayGas that matters for portable equipment
KazMunayGas: background
KazMunayGas was created by presidential decree in February 2002 by merging Kazakhoil and Oil & Gas Transportation, so it combines upstream production with pipeline and transport operations in one national group.
KazMunayGas: projects and investment
The company holds a 20% share in the Tengizchevroil joint venture, so equipment and contractor standards at Tengiz are partly shaped by international partners as well as the national company.
KazMunayGas: who works there
Its upstream arms include KazMunaiGas Exploration Production for onshore fields and KazMunayTeniz for offshore oil and gas, so site rules can differ between the land and Caspian offshore businesses.
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 KazMunayGas. In the Kazakh refinery and pipeline setting, explosion-proof is everyday shorthand for different concepts. Flameproof Ex d protects fixed electrical equipment in process units, while intrinsic safety suits portable devices. A phone used on rounds at Atyrau or Pavlodar is an intrinsic safety question, which is the concept the IS-04Z1 has been designed around.

- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · KazMunayGas
Frequently asked questions
Can KazMunayGas 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 KazMunayGas 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 KazMunayGas approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
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.
Does a partnership with Tengizchevroil change what equipment buyers should expect?
Tengizchevroil is a joint venture with international partners, so its contractors usually work to its own standards and induction process rather than to KazMunayGas rules alone. Treat the joint venture and the national company as separate customers and check each one's approved equipment requirements.
Is the Atyrau refinery a likely place for Zone 1 handheld devices?
Refineries typically contain Zone 1 and Zone 2 gas areas around process units, loading and tank farms. Because a large modernisation programme added new units, area classification may have changed. Confirm the current zoning and permit-to-work practice with refinery HSE before deploying phones.
How do Kazakh winters affect a handheld phone?
Very cold weather reduces battery capacity and can slow screens, while snow and dust are handled by IP68 sealing, which is not an explosion rating. Test the device at the lowest temperatures on your sites, keep spares warm and charge in safe areas. Check the operating range on the datasheet.
