Strategic storage
India's strategic petroleum reserve includes a 1.5 million tonne underground facility at Mangaluru, with a further one at nearby Padur.
The city is one of the locations of India's strategic petroleum reserves, which adds crude storage facilities to the area. These create hazardous areas in processing and storage. If you are specifying an Ex-proof smartphone for Mangaluru (Mangalore), Karnataka, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Mangaluru (Mangalore), Karnataka: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Mangaluru (Mangalore), Karnataka: Refinery process units, Petrochemical aromatics and polypropylene units, Underground crude storage caverns | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Mangalore India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
India's strategic petroleum reserve includes a 1.5 million tonne underground facility at Mangaluru, with a further one at nearby Padur.
MRPL was established in 1988, is a subsidiary of ONGC and has a design capacity of 15 million tonnes a year, including a polypropylene unit.
Humidity averages about 75 percent and peaks at around 93 percent in July, with a lowest average of about 56 percent in January.
Mangaluru has a tropical monsoon climate, with about 95 percent of annual rainfall from May to September and a very dry period from December to March.
The new port opened in 1968, handles about 75 percent of India's coffee and cashew exports and is India's seventh-largest container port.
ONGC held about 71.6 percent of MRPL and HPCL about 17 percent as of 2020, so the refinery sits inside the public-sector oil group.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Mangaluru (Mangalore), Karnataka. A marking check at Mangaluru should compare the device against the area, such as aromatics units, polypropylene, crude cavern access and the marine terminal. Aromatics and crude can sit in different gas groups. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, and the operator's classification governs.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Likely candidates are refinery process units, petrochemical aromatics and polypropylene units, underground crude storage caverns, marine terminal. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
The refinery includes crude distillation, hydrocrackers, reformers and a polypropylene unit, with tank farms and port connections, all with classified areas defined by the operator. Request the area classification before entering.
The period from December to March is very dry, while 95 percent of the annual rain falls between May and September. Many operators schedule outdoor work accordingly.
No. They are run by different organisations, so each classifies its own areas and sets its own equipment rules. Confirm with MRPL and with the SEZ petrochemical operator separately. Approval at one does not imply approval at the other.
