Explosion-Proof Mobile Phone in Loyang Offshore
Loyang Offshore Supply Base in eastern Singapore, near Changi Airport, is run by Toll Offshore Petroleum Services (TOPS).

This page explains what to look for in an explosion proof mobile phone for Loyang Offshore Supply Base, and where the IS-04Z1 stands against that list today.

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 Loyang Offshore Supply Base. Offshore equipment workshops, chemical and fuel storage and quay handling are different from process plants. Explosion-proof here may mean testing or storing equipment that will later enter hazardous areas offshore. Intrinsic safety suits handhelds in any such area. The IS-04Z1 is designed for intrinsic safety, so ask which concept the task needs.

Questions · Loyang Offshore
Frequently asked questions
Can we buy an explosion proof mobile phone in Loyang Offshore today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an explosion proof mobile phone in Loyang Offshore 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 areas at Loyang Offshore Supply Base would use it?
Likely candidates are offshore equipment workshops, hazardous materials storage, wharf and vessel quay handling, hot works and afloat repair areas. 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.
Who runs the Loyang Offshore Supply Base?
The base is operated by Toll Offshore Petroleum Services, part of Toll Group, and covers 32 hectares in eastern Singapore. Because it is a managed logistics site, tenant and contractor rules are normally set by the operator and by each tenant's own HSE team.
Are there hazardous areas at an offshore supply base?
Yes in places: workshops, fuel and chemical stores, and equipment being prepared for offshore service can create classified areas, while the wharf area is mostly open air. The classification varies by building and tenant, so ask the tenant for its zone plan.
Is Loyang a hazardous-area site?
Not wholly. The base has workshops, storage and quay handling, and which tenants hold classified areas has not been verified. Chemical and fuel storage may be classified. Ask the tenant's HSE team or the base operator before assuming an Ex rating is required for the task.
