The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Midland and Odessa, Texas. In the Midland and Odessa region, Zone 1 work arises in the surrounding fields at wellsites, drilling rigs, tank batteries, compressor stations and gas processing plants, not in the cities. The producer or plant owner classifies those areas. SAMS does not classify areas; it only describes its product marking.

Questions · Midland Odessa
Frequently asked questions
Can we buy a hazardous area mobile phone in Midland Odessa today?
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.
What does a hazardous area mobile phone in Midland Odessa cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which areas at Midland and Odessa, Texas would use it?
Likely candidates are wellsites and tank batteries, drilling rigs, compressor stations, gas processing plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
What is the best way to reach Midland Odessa sites from overseas?
Midland International Air and Space Port sits between the two cities and is the closest airport; most visitors connect through a larger Texas hub. Allow for long road transfers because the Permian Basin covers about 86,000 square miles.
Do oilfield sites around Midland Odessa have different needs from refineries?
Oilfield sites are spread over a large area with wellpads, tank batteries and gas processing plants, so lone-worker and coverage requirements often matter as much as area classification. Confirm classified zones and approval rules with each operator.
Who buys handhelds for oilfield crews in Midland and Odessa?
Producers and service contractors usually buy through their own procurement or field contractors, so the buyer may be a service company rather than the operator. The IS-04Z1 is pre-launch with no certificate. Ask the relevant site operator which approvals apply to contractor devices.
