Field notes · Loyang Offshore Supply Base
More about Loyang Offshore Supply Base that matters for portable equipment
Loyang Offshore Supply Base: industry on the ground
The surrounding Loyang industrial estate in Pasir Ris mainly hosts aviation-related services because of its closeness to Changi Airport, so visitors will find airport-linked businesses alongside the offshore supply base.
Loyang Offshore Supply Base: logistics and access
Its wharf can serve more than 11 vessels at the same time, so supply boats and offshore equipment move through the base continuously.
Loyang Offshore Supply Base: geography and layout
The site covers 32 hectares in eastern Singapore, close to the aviation and marine hub, which places it away from the Jurong industrial cluster in the west.
Loyang Offshore Supply Base: climate and equipment wear
Equatorial heat, humidity and sudden heavy showers affect an open wharf and yard, so portable devices used outdoors need good ingress protection and handling discipline.
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 Loyang Offshore Supply Base. The base has offshore equipment workshops, chemical and fuel storage, and port and quay handling. Tenants have their own safety rules, so classification differs by tenant and is set by the tenant, not SAMS. Ask the tenant's HSE team which areas, if any, are classified.

Questions · Loyang Offshore
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area mobile phone in Loyang Offshore cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 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.
