How trapped key interlocks can ensure the long-term safety of electrostatic precipitators

The hazards of electrostatic precipitators in power generation are well known. High-voltage current, confined spaces and the respiratory risk of fly ash all put workers in potential danger. These issues are compounded by infrequent access and harsh environmental conditions.

This is why selecting a trapped key safety system that provides protection for many years is an important factor in safeguarding power station workers.

Factors to consider when choosing a system include:

•    the product’s ability to withstand hot and cold climates
•    outdoor use
•    the impact of fly ash

This means the type of key (heavy- or light-duty), the material (brass or stainless steel) and the location of the interlocks are crucial to determining long-term usability.

This is only part of the story, though. To perform reliably over many years, interlocking systems need to be maintained and should be serviced as part of a shutdown regime. Simple preventative maintenance steps, such as using graphite powder rather than grease, have a huge impact on longevity.

Regular functionality testing of locks can also prolong a trapped key safety system’s life. This ensures the system is fully operational, saving time and money during a planned or unplanned outage. If locks are only used during an outage and they fail, it can take time to repair or replace them.

Should a failed lock prevent a power station from being brought back online, the financial penalties incurred could be severe. For this reason, it is best practice to regularly check and maintain locks between outages.

With the right maintenance plan, system selection and material choice, a trapped key interlocking system can provide 30-40 years’ service on an electrostatic precipitator, in even the harshest locations.

NSK improves loading bay safety at Netherlands warehouse

Castell’s Salvo™ also protecting staff at UK facility

NSK, one of the world’s leading manufacturers of industrial and automotive components, has chosen Castell’s drive-away prevention system Salvo™ to protect staff at its warehouse in Tilburg, Netherlands.

NSK warehouse, Netherlands, Salvo, loading bay safety, Castell

NSK’s huge facility distributes more than 4,000 pallets a month across the whole of Europe and North Africa. Customers include Ford, Volkswagen, Siemens and Bosch.

Salvo™ has been installed on 12 loading bays, while NSK has also bought four Salvo™ Club steering wheel locks to safeguard deliveries made by rigid vehicles. There have been no reported health and safety incidents since Salvo™ was commissioned at the Tilburg site.

Having reversed their vehicle onto the relevant loading bay, drivers install the Salvo™ SGL lock on the exposed emergency airline coupling, releasing a trapped key. This key is then inserted and turned in the Salvo™ Control Panel (SCP+) on the outside of the bay. An amber beacon illuminates on the inside to indicate that the loading bay is now safe and ready to use. The loader opens the door, trapping the key in the SCP+ outside. While the door remains raised and the key trapped in the control panel, the trailer cannot be moved.

NSK has also installed Salvo™ at its distribution centre in Newark, UK.

The Health & Safety Executive booklet ‘Warehousing and storage: A guide to health and safety’ recommends interlocks as a safe system of work to combat drive-aways. Salvo™ also features as an example of a safe system of work in the Freight Transport Association’s ‘Loading dock safety guide’, produced in conjunction with the Institution of Occupational Safety & Health.

Castell has launched an enhanced version of its Iso-Lok padlock range. The new range features a more complex differ code system, increasing the overall safety level offered to customers.

Iso-Lok-new-differ-code-system

Castell’s tracking system already ensures that each padlock supplied to a site is unique. This removes the issue of keys fitting multiple padlocks and therefore reduces risk in lockout / tagout procedures. The company’s enhanced range of padlocks now takes the separation of differ codes one stage further.

“The quality of the Iso-Lok range is very important to our client base,” said David Hughes, Castell’s sales director. “By increasing the integrity of our padlocks we have effectively increased the safety of the Iso-Lok range.

This product improvement – coupled with our ability to track differ codes, paint and engrave padlocks – delivers substantial value to our customers.”

Five ways trapped key interlocks can protect people in the waste industry

Safety in the waste and recycling industry is a key focus of the HSE.

The recent Waste Industry Safety and Health (WISH) Forum blueprint (PDF), produced with the HSE, highlights the sector’s potential dangers and sets out a road map to reduce risk and improve safety knowledge in the industry.

Here are five reasons why trapped key interlocks can improve safety in the waste and recycling sector:

1.    They’re foolproof and ensure equipment can only be used in a safe way.

2.    They’re mainly mechanical and easy to install and retrofit.

3.    They’re hard-wearing and can withstand harsh environments.

4.    They can be installed on the full range of equipment found at a waste and recycling site.

5.    It’s not always easy to spot when someone is in a dangerous area before a machine starts. ‘Personnel keys’ remove this risk: a machine can’t be started until the keys are returned by operatives from the hazardous area.

Fyffes chooses Salvo™ for UK distribution centres

Fyffes, one of the leading importers and distributors of tropical produce, has installed Castell’s Salvo™ drive-away prevention system at its UK distribution centres.

Fyffes, Salvo, Castell, warehouse, safety,

Salvo™ is now protecting loading and unloading operations at the company’s Livingston, Wakefield, Coventry and Basingstoke sites – a total of 31 loading bays.

“The Salvo™ system is simple, robust and secure, and gives us confidence in the safety and security of our loading and unloading operations,” said George Kennedy, Fyffes’ General Manager (UK Depot Operations).

Drivers report to the transport office and are allocated a loading bay. After reversing their vehicle onto the bay, they return to the transport office where they leave their ignition key and collect the Salvo™ Susie for that loading bay. They then install the Susie on the emergency airline coupling, which releases a trapped key. This key is inserted and turned in the Salvo™ Control Panel on the outside of the bay. An amber beacon illuminates on the inside to indicate that the loading bay is now safe and ready to use. The loader opens the door, trapping the key in the SCP outside. While the door remains raised and the key trapped in the control panel, the trailer cannot be moved.

Bonmarché banishes drive-aways with Salvo™

Clothing retailer invests in interlocking system to improve warehouse safety

Bonmarché, the UK’s largest value womenswear retailer for women aged 50+ years, has improved the safety of its loading and unloading operations with the adoption of Castell’s Salvo™.

Bonmarche(building3)

The interlocking drive-away prevention system has been installed on all seven loading bays at Bonmarché’s Grange Moor head office, near Wakefield, West Yorkshire. Grange Moor, Bonmarché’s only distribution centre, handles an average of 140,000 garments a day, although this rises to 200,000 at peak times.

Third-party drivers arriving at Grange Moor report to security and receive documentation explaining how the Salvo™ system operates. They park in a holding area, where they are met by a supervisor who checks that they understand the information they have been given. Drivers are then asked to reverse into a particular loading bay, before disengaging their engine and fitting either a Salvo™ Susie or SGL lock to their vehicle’s exposed emergency airline coupling. This action effectively immobilises the trailer and releases a key, which the driver hands to a member of the warehouse staff. Inserting and turning the key in the control panel located next to the bay door powers up the bay and enables the door to be raised. Once the dock leveller has been correctly positioned, the driver is asked to pull the cab away, park in the holding area and wait there until further notice while unloading takes place.

Goods-out follows a similar procedure, except that Bonmarché’s warehouse staff fit the Salvo™ Susie or Salvo™ Club, an interlocking steering wheel lock, to the vehicle prior to loading.

The Health & Safety Executive booklet ‘Warehousing and storage: A guide to health and safety’
recommends interlocks as a safe system of work to combat drive-aways. Salvo™ also features as an example of a safe system of work in the Freight Transport Association’s ‘Loading dock safety guide’, produced in conjunction with the Institution of Occupational Safety & Health.

New restraint prevents rigid vehicle drive-aways

Salvo™ Chock now quicker and easier to use

Industrial safety specialist Castell has redesigned Salvo™ Chock, its interlocking wheel chock, to improve its technical specifications and operational performance.

SalvoChock(new)

Castell’s design team has gone back to the drawing board to create a restraint for rigid vehicles that can satisfy the demanding conditions of the loading yard. The result is a chock that is lighter, stronger, significantly easier to use and, importantly, faster to manoeuvre.

Salvo™ is a system that restrains vehicles at loading docks while loading or unloading occurs. This is achieved through patented technology that interlocks either an exposed airline coupling, or a wheel chock, and the loading dock door. This means that while the loading door is open there is no way the vehicle can move; only when the loading door is closed can the restraining device be removed.

Paul Marks, Castell’s new product development director, explained: “To enable Salvo™ Chock to really deliver the performance required, we had to spend extensive time researching from first principles what was needed. We believe that, by creating the new Salvo™ Chock, the design team has addressed the key needs of the market.”

Launched eight years ago to prevent drive-aways in the logistics industry, the Salvo™ range has undergone significant product development in the last 12 months. New software, DockMonitor, has been designed to enhance the efficiency of the loading process by capturing operational data such as loading time, number of operations, idle time and available time. The addition of DockMonitor to the range means that Salvo™ now enables loading dock performance to be measured while still guaranteeing safety.
