Pemex: projects and investment
In September 2021 Pemex and Braskem agreed a gas supply deal and a 400 million dollar ethane terminal at Laguna de Pajaritos in Coatzacoalcos, Veracruz, adding petrochemical handling in the south-east.

Intrinsically Safe Mobile Phone for Pemex
Pemex is Mexico's state-owned oil company, founded in 1938, producing crude oil, natural gas, fuels and petrochemicals. It owns six refineries (Cadereyta, Madero, Minatitlan, Salamanca, Salina Cruz and Tula) and the newer Dos Bocas refinery, and operates offshore fields such as Cantarell in the Bay of Campeche. If you are specifying an intrinsically safe mobile phone for Pemex, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Supplier approval · Pemex
Becoming an approved supplier to Pemex
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.

More about Pemex that matters for portable equipment
Pemex: background
Pemex was established by presidential decree on 7 June 1938, following the nationalisation of the oil industry that March, and has since been run as the Mexican state petroleum corporation.
Pemex: projects and investment
The Dos Bocas refinery plant opened in 2024 and was reported to be operating at 60% of capacity, transforming about 340,000 barrels a day of crude into fuels, so new-build units are being commissioned.
Pemex: background
Small quantities of oil were first refined into kerosene around 1876 near Tampico, showing that the Gulf coast oil area has a very long industrial history and ageing plant in places.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Pemex. Operators on Bay of Campeche platforms and in refinery units walk long routes with many inspection points. A handheld intrinsically safe phone allows tag scanning, photographs and defect reports inside the classified area. It would suit routine rounds at Madero, Minatitlan and Tula and the crowded work periods of plant turnarounds.

Specifying an intrinsically safe mobile phone for Pemex
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- 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 · Pemex
Frequently asked questions
Can Pemex 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 intrinsically safe mobile phone for Pemex cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
How does Pemex 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.
How does the Gulf coast climate affect phones used on Pemex facilities?
Gulf of Mexico and Veracruz sites are typically hot, humid and salty, with heavy rain in the wet season. For handheld devices that means checking sealing, corrosion resistance and operating temperature, and asking the facility about its own environmental limits.
Which Pemex facilities usually have Zone 1 areas?
Typical Zone 1 and Zone 2 areas occur at refineries, gas processing and petrochemical plants, offshore platforms, LPG terminals and pipeline stations. Actual classification is facility-specific, so request area classification drawings from the operator before choosing portable equipment.
Do Pemex sites need Spanish-language device support?
In practice yes, since operators and maintenance crews work in Spanish. Check that the interface, MDM policies and documentation can be provided in Spanish before any pilot. The IS-04Z1 runs Android 16 with EMM/MDM support, but no certificate has been issued, and SAMS has appointed no Mexican distributor.
