Explosion-Proof Mobile Phone in Czech Republic
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Czech refineries, chemical plants, tank farms and coke ovens rather than for a catalogue. This page explains what to look for in an explosion proof mobile phone for Czech Republic, and where the IS-04Z1 stands against that list today.

Field notes · Czech Republic
More about Czech Republic that matters for portable equipment
Czech Republic: industry on the ground
The country has two refineries, both owned by Česká rafinérská, including the Litvínov refinery, so Litvínov and Kralupy are the best-known flammable-liquid processing sites.
Czech Republic: who works there
The Orlen Unipetrol group includes refineries and plants at Litvínov and Kralupy nad Vltavou, Paramo at Pardubice and Kolín, Spolana at Neratovice, and two research centres, and it is the only crude oil processor in the country.
Czech Republic: infrastructure
The Ingolstadt-Kralupy-Litvínov pipeline can bring crude oil from Germany and can be connected to the Transalpine pipeline, so crude arrives through pipeline terminals rather than seaports.
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 Czech Republic. At Litvínov, Kralupy or Třinec, the everyday phrase explosion proof covers many things. Flameproof Ex d suits fixed motors and enclosures, while the IS-04Z1 relies on intrinsic safety so a handheld can be used live near coke ovens, crackers and tank farms. The operator classifies each area, not SAMS.

Specifying an explosion proof mobile phone for Czech Republic
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 · Czech Republic
Frequently asked questions
Can we buy an explosion proof mobile phone in Czech Republic 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 an explosion proof mobile phone in Czech Republic 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.
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.
Which sites in Czech Republic does this cover?
The market guide for Czech Republic covers Litvínov and Záluží, Kralupy nad Vltavou, Neratovice, Valašské Meziříčí, among others. Site-level pages are linked below.
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.
Are Czech refineries covered by ATEX rules for handheld devices?
The Czech Republic is an EU member, so ATEX Directive 2014/34/EU applies to equipment and employers zone workplaces under Directive 1999/92/EC. Refineries such as Litvínov typically also have internal device approval and permit-to-work procedures, so ask the HSE office before bringing phones in.
What language should Czech site documents be in?
Czech is the usual site language, and ATEX user instructions are typically expected in the local language of the destination. A Czech-language instruction sheet with the certificate pack often speeds up acceptance. Ask the operator whether it also accepts English documentation for contractors.
Why does the issuing notified body matter to Czech buyers?
FTZÚ in Ostrava-Radvanice is notified body 1026, and Czech engineers recognise it on an Ex certificate, so buyers often ask which body issued one before anything else. The certificate number, issuing body and marking string will be published for checking. No certificate exists yet, as certification is in progress.
