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 Bontang LNG (Badak LNG), East Kalimantan. The classified areas here include LNG liquefaction trains, LNG and LPG storage tanks, gas pipelines and loading jetties. Pertamina and PT Badak NGL classify them, not SAMS. A buyer should obtain current zone drawings, since reactivation of idle trains may change which areas are active.

Questions · Bontang LNG
Frequently asked questions
Can we buy a hazardous area mobile phone in Bontang LNG 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 a hazardous area mobile phone in Bontang LNG 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.
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 Bontang LNG (Badak LNG), East Kalimantan would use it?
Likely candidates are lng liquefaction trains, lng and lpg storage tanks, gas pipelines, loading jetties. 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.
What kinds of hazardous areas are found around Bontang?
The main ones are LNG and natural-gas processing areas, ammonia and urea plants, and coal handling with combustible dust. Each operator classifies its own plant, so ask Badak LNG, Pupuk Kaltim or the mine for its zone drawings before bringing handheld devices on site.
Does the humid climate matter for phones used at Bontang plants?
Yes. A tropical rainforest climate with frequent heavy rain, warm stable temperatures and sea air tends to stress seals, connectors and chargers. Typically users specify good ingress protection and keep spare batteries and cleaning routines, subject to the plant's rules.
Will a handset at Bontang need to cope with marine conditions?
Jetties and coastal areas expose devices to heat, humidity and salt air. Check the rated temperature range, seals and charging contacts. Charge only in safe areas. Water and dust protection does not replace explosion protection. Confirm site practice with the operator.
