More about Incheon that matters for portable equipment
Incheon: climate and equipment wear
Incheon has a humid subtropical climate with four distinct seasons, cold north-westerly winds in winter and warm south-westerly gusts in summer, plus a strong urban heat island effect.
Incheon: logistics and access
Incheon International Airport and Incheon Port make the city a transport hub for north-east Asia, and port traffic is large enough to classify it as a large-port metropolis.
Incheon: logistics and access
Incheon International Airport opened in 2001 on reclaimed land between Yeongjong and Yongyu islands, about 48 km west of Seoul, and replaced Gimpo as the capital's main international airport.
Incheon: industry on the ground
Incheon forms the heart of the Capital Industrial Region, with major industrial parks including the Bupyeong and Juan industrial complexes, so many manufacturing plants lie close to Seoul.
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 Incheon. Hazardous areas include the LNG storage tanks, the LNG jetty and loading, gas send-out and chemical handling in the industrial complexes. KOGAS and the other operators classify these, not SAMS. Other Incheon industry such as a refinery was not verified, so a specifier should ask each operator.

Questions · Incheon
Frequently asked questions
Can we buy a hazardous area mobile phone in Incheon 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 Incheon 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 Incheon would use it?
Likely candidates are lng storage tanks, lng jetty and loading, gas send-out, industrial complex chemical handling. 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.
What hazardous activities are found around Incheon?
The industrial parks, port tank storage and fuel handling at the airport and harbour can all involve flammable gases and liquids, while bio-industry plants add chemical solvents. Each operator defines zones and permits, so ask for classification drawings for your site.
Does Incheon's climate affect handheld equipment?
The climate is mild by Korean standards, with distinct seasons, cold winter winds from the north-west and humid summers. Typical considerations are battery performance in cold weather and humidity and salt air near the port, so check device ratings against site conditions.
Is the Incheon LNG terminal the only hazardous site in Incheon?
No. Incheon also has industrial complexes at Bupyeong, Juan and Namdong with chemical handling, and other industry such as a refinery has not been verified here. Each operator classifies its own areas. Confirm with the site operator.
