Description

Valves have a prime safety function in many process industries. The opening and closing of valves in the wrong sequence can have disastrous consequences causing serious or fatal injury to operating personnel, loss of product, damage to plant and equipment and pollution of the environment.

Ensuring the safe operation of valves is essential in industries ranging from water and food production to chemical manufacture and oil refining.

Controlling the sequence of events in which process activities are conducted, has been achieved by documented instructions. However, this system is susceptible to ‘human error’, distractions. Failure to interpret instructions correctly, workload, stress, ignorance of the system, can all lead the operator to make errors, and the consequences can be disastrous.

A PETROSAFE SAFETY SYSTEMS (PSS) Interlock guides the operator through a predefined sequence with unique keys for each step. In the event when a mistake is made only then the operator will not be allowed to proceed. Either key will not fit, or the valve will be in locked position. Trapped Linear Key Interlocks are simple, mechanical devices, which can be customized to implement a safe sequence of operation in any process activity.

PETROSAFE SAFETY SYSTEMS (PSS) has developed process Interlocking Solutions for various applications such as Valve System, PSV, Pig Launching and Receiving, Tanker Loading, Critical work area locking Systems.

The PETROSAFE SAFETY SYSTEMS (PSS) offers simple, reliable and unique Interlocking Solutions with wide range of products like Single Key Bolt Interlock, Double Key Bolt Interlock and Valve Interlocks, which not only control the opening and closing sequence of process valves but also prevent their unauthorized operation.

Mechanical Interlock systems force valves to be opened and closed in the correct order.

Most accidents in the process, and oil and gas, industries are related to procedures that do not happen very often, but which can have catastrophic effects when performed incorrectly. Start-ups, shutdowns, and handovers are all good examples of processes where a slight mistake or lack of concentration can lead to disastrous consequences. By using mechanical interlocks, you force operators to follow the correct valve opening and closing procedure and so create safer working environments. Mechanical Interlock also reduce costs by preventing product spills or losses due to incorrect changeovers.

When you choose AWRING MAAD SANAT Mechanical Interlock, you eliminate human error. Using interlocks, you only allow the correct valve to be opened or closed in the correct sequence. You guide your operators every step of the way – there is no bypassing the system. Your valves are operated using a linear key, taking your operators through a specific process, following a predefined sequence, with unique keys for each step.

You can minimize your safety risks, by using AWRING MAAD SANAT Mechanical Interlock. You reduce human error, by using interlocks to guarantee your operators follow the correct steps through a key transfer principle. Your manual valve operations take place in a safe sequence – There are no short-cuts. The transfer of uniquely coded, linear keys from valve to valve, compel your operators to follow the correct process steps. You create a safer working environment for your team of operators and those that work with them. Downtime is reduced and your plant runs smoothly.
