More about Sao Paulo state that matters for portable equipment

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 Sao Paulo state. Classified areas in the state are at refinery process units, tank farms, pipeline terminals and fuel storage and loading. The city is not a hazardous-area site. Petrobras classifies each refinery, not SAMS, and Replan alone accounts for about 20 per cent of Brazil's refining.

Questions · São Paulo
Frequently asked questions
Can we buy a hazardous area smartphone in São Paulo 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 smartphone in São Paulo cost?
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.
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 Sao Paulo state would use it?
Likely candidates are refinery process units, tank farms, pipeline terminals, fuel storage and loading. 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 Sao Paulo state?
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 Sao Paulo state.
Why do suppliers locate offices in Sao Paulo?
Because large corporations, banks and engineering contractors are based there, and Santos port is within 79 km. This does not replace site approvals, so confirm the operator's vendor registration process.
Where are the hazardous sites near Sao Paulo?
Not in the city centre but at refineries and petrochemical plants in the state, such as Replan at Paulinia, RPBC and Capuava, plus fuel terminals and pipelines. Confirm the site and its classification with the operator.
Is Sao Paulo city a hazardous area?
The city itself is not a refinery site. The state hosts four Petrobras refineries, Replan, Revap, RPBC and Recap, in other municipalities. Check which plant the handset will visit. Confirm documentation requirements with the site operator and its HSE team.
