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 Singapore refineries. At a refinery, explosion-proof is a casual label. Flameproof Ex d protects fixed motors and junction boxes, while a handheld phone in process areas relies on intrinsic safety. The IS-04Z1 is designed on the intrinsic-safety concept. Certification is in progress, and each refinery's equipment rules still decide use.

Questions · Singapore Refinery
Frequently asked questions
Can we buy an explosion proof mobile phone in Singapore Refinery 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 in Singapore Refinery 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.
Which areas at Singapore refineries would use it?
Likely candidates are refinery process units, crude and product storage, jetties, utility and cogeneration areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Singapore refineries?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Singapore refineries.
Can I use a phone inside a Singapore refinery?
One refinery on Jurong Island publishes a ban on mobile phones and other electrical or electronic equipment in its process plant and classified hazardous areas. Devices certified for the zone may be allowed only with prior approval, so ask your sponsor before the visit.
What does a refinery visit involve in practice?
Typically a visitor pass at the island checkpoint, a plant security pass, an indemnity form, security screening, declaration of electronic equipment and an escort by a named sponsor for the whole visit. Allow extra time at the gate and arrive with approved paperwork.
Do hydrogen units change the marking needed?
Hydrogen is a Group IIC gas, so any unit handling it can call for IIC equipment, whereas many fuels fall in IIA or IIB. The IS-04Z1 target marking includes IIC but is not yet issued. Ask the refinery which units hold hydrogen.
