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 Visakhapatnam (Vizag), Andhra Pradesh. Refinery process units, crude and product tanks, underground cavern storage and berths at the single point mooring are the classified areas here. Each site operator, HPCL or ISPRL, classifies its own areas. SAMS does not classify anything, and buyers should request the operator's zone drawings.

Questions · Visakhapatnam India
Frequently asked questions
Can we buy a hazardous area mobile phone in Visakhapatnam India today?
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.
What does a hazardous area mobile phone in Visakhapatnam India 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 Visakhapatnam (Vizag), Andhra Pradesh would use it?
Likely candidates are refinery process units, crude and product tank farms, underground strategic crude storage, port petroleum berths and single point mooring. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Visakhapatnam (Vizag), Andhra Pradesh?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Visakhapatnam (Vizag), Andhra Pradesh.
Does monsoon weather affect handheld equipment used outdoors at Vizag?
Yes. Rainfall of roughly 1,100 mm a year, mostly in the monsoons, plus coastal humidity and salt air, mean outdoor users usually want good ingress protection, sealed ports and regular cleaning of connectors. Check the rating against your site specification.
Which hazardous-area industries are concentrated in Visakhapatnam?
The main clusters are the HPCL Visakh refinery, the port with its bulk cargo handling, the steel plant and its coal and ore supply chain, and the shipyards. Gas, vapour and combustible dust zones all arise, so confirm the classification with each site.
Can a contractor bring any new handset into the Visakh refinery?
Not by default. Entry of electronic devices is governed by the operator's permit and equipment approval rules, which contractors must follow. A device in certification would normally need operator acceptance first. Confirm with the site operator's HSE team before planning any trial.
