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 Baytown, Texas (ExxonMobil Baytown complex). Baytown has refinery process units, ethylene cracking units, chemical plant units and Ship Channel storage and docks. ExxonMobil, Chevron Phillips Chemical and Covestro each run large plants, and each operator classifies its own areas as Class I Division or Zone locations. SAMS does not classify any area.

Questions · Baytown Refinery
Frequently asked questions
Can we buy a hazardous area mobile phone in Baytown Refinery today?

What does a hazardous area mobile phone in Baytown Refinery 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 Baytown, Texas (ExxonMobil Baytown complex) would use it?
Likely candidates are refinery process units, ethylene cracking units, chemical plant units, ship channel storage and docks. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
