Isolation System

‘Explosion Isolation systems prevent the propagation of flame and/or high pressure from one part of the process to another through the use of fast-acting explosion isolation valves and/or chemical barriers. This is achieved through valves or chemical suppression systems. In chemical suppression, a rapid discharge of a chemical explosion suppressant is applied near the explosion source to prevent the flame from continuing through to other areas of the process system. The explosion isolation valve prevents the spread of flames and pressure (in both directions), effectively preventing an explosion from moving through your process plant, piping or duct work.’

 ‘Isolation involves disconnecting or separating the energy source, to protect the health and safety of people and also equipment and machinery from damage. Isolation shall provide positive protection and be achieved by the use of safety lockout padlocks, tags, safety lockout jaws/hasp, blanking off pipelines, gate and ball valve lockout devices, and/or establishment of a physical barrier or separation.’ Isolation can also be provided by the automatic activation of emergency isolation hardware.
