Mechanical Safety Interlocking for Simple and Complex Pig Trap Procedures

Pig trap accidents caused by operator error can be prevented using Smith Flow Control’s (SFC) key interlock systems.

Mechanical key safety interlocking is the only technology that can meet the universally accepted safety requirement for loading and unloading pig traps by ensuring that the vessel is vented before it is possible to open the vessel closure. Operators cannot bypass the safety system and this eliminates the risk of ‘operator error’.

SFC interlocks can be specified to ensure the minimum safety arrangement of interlocking the vent valve with the pig trap closure; this guarantees that the vent is open and depressurised before the operator is permitted to open the closure door.

Motor operated valves (MOVs) are frequently used and interlocked as part of the pig trapping procedure because valves are too large and cumbersome for manual operations. When power actuated valves need to be interlocked with manually operated valves and the vessel closure, the key interlock system verifies the valve’s position (open and/or closed), independent of any on-board instrument indication. In the event of a power failure during these procedures, the integrity of the key sequence is maintained even if the valve is to be operated manually. This is achieved by inserting a coded key into the interlock fitted to the manual override hand-wheel assembly which engages the drive mechanism; other coded keys in the sequence are only released once the valve has completed its full stroke.

Sometimes operating sequences on launcher/receiver systems can include complex variations. The range of process applications to which SFC interlocks can be applied is unlimited and tailored systems can be designed for specific client process requirements. For example, the simplest interlock system is linear but, on occasion, non-linear sequences are necessary to incorporate the control of complex Nitrogen purging, pressure equalisation, venting and draining. For this SFC has designed a Sequence Control Unit (SCU) which is a mechanical key issuing device located close to the valve. It differs from the traditional key exchange units in that, upon inserting a permit key, a selector knob is rotated to a fixed position before the next key is issued. In this way, complex sequences can be accommodated, using the same safety principles.

The final, major part of the sequence involves interlocking the vessel door.  SFC’s DL3 interlock device is customised to suit any make or type of enclosure door and completes the safety interlock solution for the safe operation of a pig launcher/receiver system.  The DL3 interlock ensures total isolation before the vessel door can be opened.  When the DL3 is incorporated into vessel access safety procedures, total equipment and personnel safety is assured.

Gas Safety in Confined Spaces

A confined space is any space large enough for someone to enter and perform assigned work, which has limited means of entry or exit, and which is not designed for continuous worker occupancy. This covers just about every industry, including utilities, construction, hydrocarbon exploration and processing, petrochemicals, marine, agriculture, food processing and brewing, as well as the emergency services.

Employers must assess the risks these workplaces pose to their employees and endeavour to prevent them.  In most cases, both the assessment and the safe working system will require testing of the atmosphere with gas detection equipment.

Crowcon’s Gas-Pro multi-gas detector is ideal for this purpose. Robust, reliable and simple to use with a bright, easy to read display and long battery life, it means personnel entering confined spaces can focus on the task in hand, safe in the knowledge that their gas detector is watching their back.

Crowcon’s Gas-Pro multi-gas detector is ideal for use in confined spaces.

Crowcon’s Gas-Pro multi-gas detector is ideal for use in confined spaces.

Confined space gas risks can be divided into three broad categories: combustible gas, toxic gas, and oxygen depletion or enrichment.

Combustible gas risks
For combustion to occur the air must contain a minimum concentration of combustible gas or vapour. This quantity is called the lower explosive limit (LEL). Different compounds have different LELs so it’s vital that detectors are capable of detecting at the correct levels.

Typically, storage vessels which have contained hydrocarbon fuels and oils present a danger.  Other dangers come from fuel leaks: burst fuel containers; pipelines on and off site, gas cylinders and engine-driven plant. For workers in pits, sewers and other sub-surface locations, methane formed by decaying organic matter is an almost universal danger.

Toxic gases and vapours
Confined-space workers may be exposed to many toxic compounds, depending on the nature of the work.  A risk assessment should be made of which toxic substances a worker may be exposed to in any given work situation.

When looking at toxic gases related to specific applications, the water industry for example uses many toxic compounds for cleaning and processing both waste and clean water. Hazards such as chlorine, ozone, sulphur dioxide and chlorine dioxide then pose additional risks both in storage and treatment areas.

Oxygen – too high or too low?
The normal concentration of oxygen in fresh air is 20.9%.  An atmosphere is hazardous if the concentration drops below 19.5% or goes above 23.5%.

Without adequate ventilation, the simple act of breathing will cause oxygen levels to fall surprisingly quickly. Combustion also uses up oxygen, so engine-driven plant and naked flames such as welding torches are potential hazards. Oxygen can also be displaced.  Nitrogen, for example, when used to purge hydrocarbon storage vessels prior to re-use, drives oxygen out of the container and leaves it highly dangerous until thoroughly ventilated.

High oxygen levels are also dangerous.  As with too little, too much will impair the victim’s ability to think clearly and act sensibly.  Moreover, oxygen-enriched atmospheres represent a severe fire hazard.

Gas detector types
Both portable and fixed gas detectors can be used for confined space monitoring.  Fixed systems typically comprise one or more detector “heads” connected to a separate control panel. If a detector reads a dangerous gas level, the panel raises the alarm by triggering external sirens and beacons. This sort of installation is suited to larger spaces like plant rooms, which have sufficient room for the hardware or remote stations that are usually unmanned.

However, much confined space work takes place in more restricted areas, making compact portable units more suitable. Ease of use, with one button operation, means minimal training is required while increased safety is ensured.  Combining one or more sensors with powerful audible and visual signals to warn when pre-set gas levels are reached, portable detectors can be carried or worn wherever they are needed. In addition, a compact instrument is easily carried in a confined space, ensuring that pockets of high gas concentration are not missed.

Certain features should be expected in every portable gas detector.  Clearly, life-saving tools for demanding environments must be as tough as possible, with reliable electronics housed in impact-resistant casings.  While the need to leave gas sensors exposed to the atmosphere means that no instrument can be fully sealed, a high degree of protection against dust and water ingress is essential.  Toughness notwithstanding, a well-designed detector will also be light and compact enough to wear for an entire shift.

Finally, because of the difficulties of working in a cramped space, perhaps under poor lighting, instruments should be easy to use.  No matter how advanced a detector’s internal architecture or data management options, personnel in the field should be faced with nothing more daunting than a clear display, simple, one-button operation and loud/bright alarms.
