Singapore: rules and approvals
The Ministry of Manpower enforces explosive-atmosphere duties under the Workplace Safety and Health Act, while the Singapore Civil Defence Force regulates flammable-materials storage under the Fire Safety Act.
The IS-04Z1 is an intrinsically safe Zone 1 and Zone 21 handset for people who work inside classified areas on Jurong Island, at Pulau Bukom and around the Tuas terminals: process operators, inspection and maintenance engineers, turnaround crews and the WSH and IT teams who equip them. This page sets out how an explosion proof smartphone supply route to Singapore will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An explosion proof smartphone for Singapore cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Singapore market guide covers.
The Ministry of Manpower enforces explosive-atmosphere duties under the Workplace Safety and Health Act, while the Singapore Civil Defence Force regulates flammable-materials storage under the Fire Safety Act.
Singapore sold 56.775 million tonnes of marine fuel in 2025, making it the largest bunkering port in the world by a wide margin and keeping fuel handling and barge work active around the clock.
SLNG plans a second LNG terminal offshore, slated to operate by the end of the decade, in addition to the existing Jurong Island terminal, so new gas-handling sites are expected over the coming years.
IMDA registers telecommunications equipment under a supplier's declaration approach. Cellular mobile devices, including 5G and LTE, fall under Simplified Equipment Registration, while base stations and similar higher-risk products need a recognised certification body.
“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. Explosion-proof is used loosely on the island, but the plants hold varied atmospheres. A flameproof Ex d enclosure suits fixed equipment, while intrinsic safety, the protection concept of the IS-04Z1, limits the energy of a handheld. On Jurong Island the practical question is which concept a handset uses for hydrogen or acetylene areas.
There is no stock to order for Singapore yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
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.
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.
The market guide for Singapore covers Jurong Island, Pulau Bukom, Seraya and Merbau, Pulau Sebarok and Pulau Busing, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Singapore adopts IEC 60079 as SS EN 60079, and both IECEx and ATEX certificates are built on that technical base. Many operators accept either, but an individual refinery or yard may name one scheme in its specification, so confirm with the operator's HSE or instrumentation team.
Cellular mobile devices are generally registered with IMDA under the Simplified Equipment Registration route, which relies on a supplier's declaration of conformity. The registration is valid for five years, and the registering supplier is typically a local entity. Confirm the exact route for a specific model with IMDA or a local compliance adviser.
The design pairs a 4,000 mAh battery with IP68 sealing so the unit lasts through a shift where a spare may be a boat away. Charging stays in a safe area. Test battery life on a typical round and confirm access rules with the island operator.
