Field notes · Sao Paulo state
More about Sao Paulo state that matters for portable equipment
Sao Paulo state: climate and equipment wear
São Paulo has a humid subtropical climate, and heavy storms can bring more than 140 mm of rain in 24 hours, so outdoor and plant-yard work needs weather protection for portable equipment.
Sao Paulo state: logistics and access
Replan serves the interior of Sao Paulo state (about 55 percent of its output) and parts of Mato Grosso, Mato Grosso do Sul, Rondonia, Acre and southern Minas Gerais.
Sao Paulo state: logistics and access
The Port of Santos is 79 km from Sao Paulo city and is reached by the Anchieta and Imigrantes highways, which carry most import and export freight for the region.
Sao Paulo state: industry on the ground
Replan started operating in 1972 on about 9.1 km2, with capacity of 66,000 m3/d, and makes gasoline, diesel, LPG, aviation kerosene, asphalt, petrochemical naphtha and propane.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Sao Paulo state. The city itself is not a refinery site, so explosion-proof applies at state refineries: process units, tank farms, pipeline terminals and fuel storage and loading. Fixed gear may be flameproof Ex d, while a portable handset relies on intrinsic safety. The IS-04Z1 is designed for that, pending certification.

Specifying an explosion proof mobile phone for São Paulo
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · São Paulo
Frequently asked questions
Can we buy an explosion proof mobile phone 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 an explosion proof mobile phone in São Paulo 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
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.
How long does equipment take to reach Sao Paulo state?
Imports usually clear through Santos and travel by highway, but customs and radio approval can add time, so allow a margin. Confirm clearance steps with a local agent early in the project.
What does a Replan visit usually involve?
Typically a gate induction, a permit system and equipment checks at one of Brazil's largest refineries. Confirm with the contractor which zones you will enter and whether your devices need Ex certification and local radio approval.
Does one approval cover all the state's refineries?
Not by assumption. Each plant has its own classification and procedures, and purchasing is usually through registered-supplier processes. Ask each operator for its Ex equipment policy and obtain the area classification for the specific unit before ordering.
