More about Cardiff and Roath Dock that matters for portable equipment
Cardiff and Roath Dock: background
Cardiff became the main port for coal exports from the Cynon, Rhondda and Rhymney valleys after the Marquess of Bute built a dock in the 1830s linked to the Taff Vale Railway.
Cardiff and Roath Dock: geography and layout
Cardiff is the capital of Wales, with 381,516 residents in 2025, and sits in the Cardiff Capital Region of 1.5 million people, roughly half the nation's population.
Cardiff and Roath Dock: logistics and access
Rival docks at Barry were promoted in the 1880s because they were accessible in all tides, which shows how strongly tidal range on the Severn Estuary and Bristol Channel shapes port operations.
Cardiff and Roath Dock: climate and equipment wear
Cardiff has a maritime climate with an average annual temperature of about 11 degrees Celsius and about 1,200 mm of rain on 153 days a year, with more than 100 mm a month from October to January.
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 Cardiff and Roath Dock. The classified areas at Cardiff are the fuel storage and distribution terminal, the marine jetty during tanker discharge and the road tanker loading area. The employer assesses these as hazardous zones under DSEAR, and the operator or its safety adviser, not SAMS, decides the zone extent. The city beyond the dock has no comparable classified areas.

- 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

Questions · Cardiff
Frequently asked questions
Can we buy a hazardous area smartphone in Cardiff 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 Cardiff 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 Cardiff and Roath Dock would use it?
Likely candidates are fuel storage and distribution terminal, marine jetty and tanker discharge, road tanker 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 does Cardiff's weather affect handheld devices outdoors?
The maritime climate is mild but wet, with rain on about 153 days a year and persistent wind from the Bristol Channel. Typically users want good water ingress protection and routine drying and cleaning of connectors, and should check the device rating against the site.
Is Cardiff a heavy-industry location for hazardous-area equipment?
Not mainly. The city is Wales's commercial and administrative centre, and the old steelworks closed in 1978, though the wider Severn Estuary and South Wales coast host fuel, energy and processing sites. Confirm the operator and site classification for the actual place you will work.
Who decides what equipment is allowed at Cardiff's fuel terminal?
Under DSEAR, the employer assesses hazardous zones and chooses suitable equipment, so the terminal operator and its safety adviser decide. Valero occupies the terminal and Associated British Ports runs the dock. Confirm requirements with the site operator before specifying any handheld device.
