A Safezone enclosure allows hot work to be carried out in a clean, safe and hazard free manner, without the need to shutdown the operation of a drilling platform, a refinery or pipeline operations.
It enables personnel to safely carry out repair and maintenance rapidly and safely.
Using only the highest quality materials the pressurised system comprises of flame retardant panels that will protect your workforce from the risk of fire. The system is a modular solution that is easy to transport from location to location. This allows the system to be configured and adjusted to any shape or size. You can build around any obstacle and seal pipes, valves, beams, etc.
Cunningham is a world-leading manufacturer of bespoke clever protective covers; with over 40 years’ experience protecting high value-assets across the world.
Serving clients in over 40 countries, there are few parts of the world we have not delivered to.
Safezone - a portable protective work enclosure Safety is paramount, so it makes sense to do everything possible to minimise the risks associated with hot work. That’s exactly what Cunningham is helping some of the major players in the energy industry to do.View full case study
A Pressurised Habitat, Hotwork Habitats or Welding Enclosure (as they are all commonly known) is an apparatus that could be used to conduct welding in potentially hazardous environments. There are many companies on the market that are available to hire pressurised habitats and Cunningham is such a company with their Product offering SafeZone Habitats.
SafeZone is an Engineered control measure that is used to segregate hotwork ignition sources and non-Ex Electrical Equipment from potentially hazardous environments. This means that the system is creating an non-hazardous area in Zone 1 or Zone 2 classified area. This is the equivalent to creating a gas-free zone and removing the risk of explosion.
Traditionally Oil and Gas Companies would be the biggest user of habitats (Downstream, Mid Stream and Up Stream) that would use pressurised habitats. This is due to legislation within Europe (DSEAR) which stands for the Dangerous Substances and Explosive Atmospheres Regulations 2002. The name given to the legal requirements in Europe is ATEX and around the world IECEX.
Yes, SafeZone can be built around objects, cable trays, pipe racks or any very congested area that you would typically find within facilities. The habitat can be used to seal around bulkheads, vessels or even used weld areas of the floor.
The system is made from completely flexible flame-retardant panels. These panels are able to be assembled in a infinitive amount of configurations to construct a habitat of any shape, size or design.
SafeZone is a fully reusable system that can be installed on the petrochemical facility within a few hours. The system can then be moved from location to location and disassembled ready for the next workscope. Unlike other systems where you would need to dispose of the material afterwards.
In order to understand how SafeZone works, you first need to understand and appreciate how explosions and fire are started. In order for a fire to start, you must have 3 main components. Fuel, Some Heat and Oxygen.
Containment (Containing Sparks)
A sealed, flame retardent Room is created that ensures the ignition sources (Welding, Burning and Griding) are contained within the sealed Habitat
Pressurisation (Keeping Fuel Out)
The SafeZone is overpressurised with a ventilation system that creates a positively pressurised environment. This air is ducted through antistatic ducting from a Safe Area. This creates a pressurised barrier and ensures that the SafeZone Habitat stays gas-free, even during an unplanned release from surrounding plant and equipment.
Gas Detection and Automatic Shutdown
The Cunningham SafeZone Habitat System is fitted with fully automatic shutdown and gas detection system that triggers on the presence of hazardous gas within the vicinity of the enclosure or within the air stream being ducted into the enclosure.
If the Pressure Control System picks up hydrocarbons then the system will automatically shutdown welding equipment, sound an audible and visual alarm and automatically disconnect and shut down the welding equipment and making the area safe.
