Sellafield Ltd. will get safety system from ASL
Nuclear facilities require special security measures, as they are prone to hazards and fatal accidents

ASL Safety & Security have supplied a high-integrity building evacuation system (BES) to Sellafield Ltd at the company's nuclear processing facility in Cumbria. Sellafield currently performs multiple tasks geared towards decommissioning the UK's nuclear legacy as well as fuel recycling, manufacture and waste management.

As a key safety system at this nuclear-licensed site, the equipment is required to be entirely dual redundant, with emphasis placed on a design that meets key objectives for a robust architecture, unaffected by environmental and electromagnetic factors as defined in BSEN 61000-6-4 and BS EN 61000-6-2. The system also meets the stringent BS5839:8 standard for voice alarm systems.

Nuclear facilities have unusual requirements and safety is so critical at this location that a 'confidence tone' is broadcast at 15-second intervals around the clock. The presence of these regular pips reassures personnel that the evacuation system is functioning correctly.

If an event is activated manually by criticality incident detectors or activity-in-air monitors specific to a building, a distinct warning tone is broadcast within 300 milliseconds and the location in question is evacuated. At the same time, "Keep Out!" warning beacons are triggered throughout the evacuation zone. Local residents are automatically contacted by telephone and can also ring a number to hear a description of various emergency sirens.

Failure of any of the components will not affect the operation of the system as a whole. The amplifiers employed are ASL's M400 rack-mounted main frame units which use the company's unique class-D adaptive technology to minimise power consumption, meaning a reduced sizing requirement for battery back-up. The system features dual power supplies, routers and standby amplifiers modules with speaker line monitoring and automatic switching carried out via DC surveillance.

Optimize Your Firefighter Training Program
Optimize Your Firefighter Training Program

Want to know an easy way to judge the quality of a fire department? Look at how much they train. Career, volunteer or combination, fire departments become successful through training. Yet all training is not equal. Focus too much on hands-on training (HOT) and you could be missing important legal and compliance updates. Lean heavily on web-based training and you may fail to identify shortcomings in skills proficiencies. Keep students confined to a classroom and you may lose their interest quickly. Not surprisingly, a balance of all three types of training is needed to produce competent, empowered firefighters. For this article, I was challenged to think about what’s missing from our current fire training programs. As I thought about the varied way we approach fire training, three issues jumped out at me. Base training on facts and statistics Take advantage of new technologies Incorporate policy into your training   Your training program should also be strong in the types of calls you respond to most Base Training On Facts And Statistics If your department has a robust training program, outlined by a calendar of various topics and employing a mix of HOT, online and classroom training, you’re ahead of the curve. But even in departments with well-developed training programs, training is often based on preference or habit, not data. Think about the topics in your training program. Do you know why they’re included? Do they match your call make-up? Are they targeting specific skill shortcomings? (And yes, we all have them!)What’s missing from many fire department training programs is a detailed needs assessment What’s missing from many fire department training programs is a detailed needs assessment that in turn establishes a factual basis for the year’s training topics. The needs assessment should include: Surveying the members to determine the types of training they want or feel they need. Measuring firefighter proficiency on basic tasks, such as NFPA 1403 drills, NFPA 1710 drills and EMS patient assessment skills audits, to assess personnel by mandate or by industry best practice. This will identify skills deficiencies to address through training. Incorporating call volume statistics and details. A significant percentage of the calls fire departments respond to are EMS and vehicle extrication But I’d venture to guess the training programs of most departments don’t match those percentages. Yes, you need to train for the high-risk, low-frequency tasks. But your training program should also be strong in the types of calls you respond to most. Incorporating these “facts and stats” into your training program will help you keep it fresh, relevant and interesting. Firefighters can use their phones and tablets to access department training information and complete training assignments Take Advantage Of New Technologies There is something to be said for back-to-the-basics, keep-it-simple firefighter training. But it’s a mistake to ignore technological advances. From teaching safe apparatus backing procedures to practicing hoseline deployment and Vent/Enter/Isolate/Search (VEIS) tactics, instructors have more options than ever before. Some instructors regard simulators as second-rate to “the real thing.” Certainly, simulation and other forms of technology-driven instruction can’t replace the value of hands-on experience. But they can augment it in important ways. Driver simulators, for example, not only save money because apparatus don’t have to be taken out of service or sustain wear and tear; they also provide an environment where firefighters can learn without risk of injury. If sitting behind a computer isn’t your kind of thing, live-burn simulators, vehicle fire simulators and hazmat simulators are available—and they all significantly boost training efficiency.Technology will never replace hands-on instruction, but it can facilitate it But you don’t need fancy simulators to incorporate technology into your fire training program. Learning management systems (LMS) are another important tool that can increase training program efficiency. Although they’ve been around for a long time, LMS continue to improve. The ability to integrate with mobile devices is huge, allowing firefighters to use their phones and tablets to access department training information and complete training assignments. Leveraging this technology can allow you to more efficiently manage information, schedule training and free up valuable time needed for other important tasks. If you’ve attended some of the larger regional or national fire conferences recently, you may have had the opportunity to see audience response technology in action. By capturing the firefighters’ responses to questions in real-time, instructors can adjust the material to reflect students’ knowledge level. Audience response is also simply a great way to keep firefighters engaged. Technology will never replace hands-on instruction, but it can facilitate it. If you’re using training methods that haven’t changed in decades, something’s missing from your training program.   Without incorporating policy into your training, you’re only giving your firefighters half the equation Incorporate Policy Into Your Training I saved the biggest and best for last. When I work with fire departments across the country, I repeatedly discover the failure to incorporate policy into training. Think about it: Training curricula are almost always designed around procedures—the how of doing something. But isn’t the why just as important? And that’s what policy is all about. Without incorporating policy into your training, you’re only giving your firefighters half the equation.Inevitably firefighters will encounter times when following the procedure isn’t possible Inevitably firefighters will encounter times when following the procedure isn’t possible. That’s when policy training kicks in—firefighters understand the fundamental objective, and they can think on their feet about how to achieve it. Training on policy also helps departments address the issues that so often get firefighters into trouble. How many of your firefighters really understand your department’s social media policy? What about the rules surrounding sick time usage? These are things that trip up firefighters time and time again. If you’re not training on policies, it’s unlikely firefighters remember them. How many of your firefighters really understand your department’s social media policy? In addition, normalization of deviance is a risk to every organization. When personnel fail to follow policies and no negative repercussions result, it can quickly establish a new normal. Policy-based training resets the “normal” and makes sure that members of the organization comply with the policy and not what they think the policy says.Most line-of-duty death reports cite failure to comply with policy or lack of adequate policy Fire instructors often avoid training on policy because they regard it as boring or unrelated to what really matters—firefighter safety and survival. Yet most line-of-duty death reports cite failure to comply with policy or lack of adequate policy as contributing factors in the incident. If you’re worried that policy will make your training program dry and uninteresting, link it to real-world events. An online search provides lots of examples of when things went wrong and how adherence to policy might have produced a different outcome. And limit policy training to small chunks. Take out a 10-page policy and go through it line by line, and your students’ eyes will glaze over in seconds. Instead, look for ways to enrich your current training by bringing relevant pieces of policy into it. Your firefighters will be learning the department’s policies without even realizing it! Focus On Continuous Improvement Fire chiefs and fire instructors have a challenging job. Budgets are tight, and training is often one of the first things to be cut. Yet we need firefighters to be proficient in all-hazards response. Every department has a long training wish list. But if we focus on continuous quality improvement, we can get a little better each year. Looking for opportunities to incorporate statistics, technology and policy into our training is a good place to start.

Integrated Life Safety: How Smart Buildings Offer Effective Fire Detection
Integrated Life Safety: How Smart Buildings Offer Effective Fire Detection

The era of “smart buildings” is here, bringing new opportunities for significant gains in efficiency, safety and environmental protection. In an interview, Rodger Reiswig, director of industry relations at Johnson Controls Global Fire Protection Products, offers his insights into the impact of smart buildings on fire detection and what it means for organisations planning new facilities. Q: How do you define smart buildings? The term “smart buildings” means different things to different people. For some, it’s all about the Green Initiative. Is the building able to sustain itself or reduce its carbon footprint? Can they reuse some of their water or generate electricity from onsite solar cells or wind turbines? Another definition of “smart buildings” is based on sensors. Is the building smart enough to know that, if I’m the first person there in the morning and I swipe my card, it should switch the HVAC system into occupied mode? Can it start to turn the lights on? Can it adjust the window shades to allow the sun to come in? Can it call the elevator down for me because it knows that I’m in the lobby and I’m going to the tenth floor? It’s all about how the systems integrate with one another, not just providing information to each other, but also interacting with one another, causing things to happen from one system to another. Q: How close are we to the vision of an integrated intelligent building where all the systems work together? We’ve already been doing some integration for a few years now with things like HVAC and lighting. Now we’re seeing tighter integration where, for example, we can use the position of the sun to get the best impact of sunlight to start to heat the building in the winter. One of the biggest challenges that we see in the smart building environment is protocols or topologies for how one system talks to another. The fire alarm system uses a certain protocol or language. The HVAC system uses another protocol or language, and so on. Creating an environment where systems can talk to one another and not just send, but also receive information – that’s the difficult part. Everybody can send information out. It’s easy for me to tell you what is happening in a system. But for you to tell me what’s happening in your system and then expect me to do something with that information, that’s when it gets a little bit harder. Q: What makes system-to-system communication challenging? Because of the critical role they play in protecting lives and property, life safety systems require a level of reliability and resilience far beyond that of other building systems or networks. Therefore, we have to be extremely careful about how we allow information from other systems to come into the life safety system, in case that information should affect the performance of the system. In addition, the design and specification of life safety systems is guided via three different means: building codes, standards and listings. Each of those means is controlled by different organisations. Any proposed changes to life safety networks have to pass muster with those entities, and that takes time, effort and consensus-building. When we’re talking specifically about system-to-system communication, the listing entities, organisations like UL and FM Global, regulate how much information can come into any life safety system. The listing documents require that there be some type of a barrier or gateway to prevent unauthorised or corrupted information from coming into a fire alarm system, causing harm or causing it to lock up. Life safety systems require a level of reliability and resilience far beyond that of other building systems or networks We will see all building technologies become more integrated over time as we work through the different entities and people begin to realise the benefits of improved safety, lower environmental impact, and reduced costs. Q: How will fire detection systems benefit from other sensor information available in a building? One of the things being explored is occupancy sensors that tell where people are located in a building. Some type of telemetry could be used to understand where people are concentrated in a facility and, based on that, make the fire alarm system more or less sensitive to smoke. If a lot of people are congregating in one area, there might be more activity and more dust being stirred up. You could use that information to set different alarm parameters compared to, for example, an empty building with no significant air movement. We see that type of operation happening. Knowing how many people are in a building and where they are located is also a critically valuable piece of information for first responders. Here’s another example: let’s say we have a big parking garage next to a mall. Cars come in, and perhaps some people leave their cars running, or the cars aren’t operating as efficiently as they should be. You could have carbon monoxide detectors and occupancy sensors in the garage, and when the garage becomes crowded and carbon monoxide levels start to rise a bit, you could tell the fire alarm system not to go into alarm, but instead to turn fans on to get some fresh air moving throughout the building. It’s performing a life safety function, but at a non-emergency level. Q: Are you involved in any cross-industry standard-setting organisations to enable better communication among building systems? On an industry level, Johnson Controls is very active in the development of codes and standards. We have people who sit on committees for things like healthcare occupancy standards. We have engineers that contribute to product listing documents. We have people who participate in committees that determine how products should be installed and maintained. We’re even involved with groups, like the National Disabilities Rights Network, that advocate for laws that promote equal access and notification of life safety events. The list goes on. Fire alarm systems couldbe used to detect and solve non-emergenciesbefore they become threats Just to give you an example, there’s a standard called BACnet, Building Automation Control Network, which was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. It’s a common protocol that allows all types of systems to get on the same communication platform and be able to send and possibly receive information, depending on the product and the type of system it is. BACnet is based on entities, so within their system, they need to define what each entity is. What is a thermostat? What is a variable air box? What is a lighting controller? What is a fire alarm smoke detector? We work closely with this organisation to create entities that can reside on their infrastructure so that, for example, the lightning system recognises what a smoke detector is when they send that entity out to the network. It’s one of the most important methods we are using to communicate among dissimilar systems. Integrated systems mean elevators could be used to evacuate people in an emergency We’re working on two fronts: internally and industry-wide. We’re developing third-party interfaces that enable an outside entity to sign a non-disclosure form and get the keys to the kingdom, if you will, on our protocols for how our systems operate – the data stream that we can send out and receive back – allowing that third-party developer to create some of these interfaces themselves. That has been one of our challenges, because we have always said that this is a fire alarm system, and if you want that type of an interface, we need to write it and get it listed. We had to step back and say, what if we developed a barrier gateway and allowed somebody else to develop the protocol and, done properly, became able to receive and send information to the fire alarm system? It’s like what Apple does with apps. We are going down that road with this third-party interface gateway. Q: Have these developments changed how you’re planning for the future development of fire detection systems? Yes, they have. We are looking at how we can use these systems strategically to make life safety systems better. And life safety is becoming more nuanced, proactive and comprehensive. Can I communicate and use this information to unlock the door so people have a clear egress? Can I start to use the elevators to evacuate people during an emergency? We’ve been told traditionally to use the stairwell and not the elevator in the event of a fire. But it takes a person about a minute a floor to get out. That’s a problem if you’re in an 80-story building. You have elevators sitting there. Is there something we could do to allow these elevators to be used to evacuate people? The American Society of Mechanical Engineers has been working hard on developing the language and requirements to do that. It’s just one example of how having systems integrated and talking to each other allows us to create smarter solutions that can help make facilities safer. Q: What advice would you give to building owners, architects, designers or contractors to help them start planning today for the future of smart buildings? The most important thing is to build awareness. The average building owner doesn’t know that a lot of this technology even exists. We need to inform them that there are options they can ask about. One of my recommendations would be to ask your design engineer. As you discuss the kind of windows you want, the kind of flooring and lighting and so on, ask how these systems could integrate together and what the benefits of integration would be. The bigger your facility, the greater the benefits of integrating these systems. Another resource that people don’t use often enough is the AHJs, the authorities having jurisdiction. That’s the local fire marshal, the fire chief, the local first responders. Don’t be afraid to sit down with a fire marshal, tell them what kind of building you’re putting in, and ask them what would help them respond in the event of an emergency in that building. They’ll be glad you asked, because these people see a lot of different buildings and respond to emergencies every day.

Mobile Firefighting Systems Provide Flexible Fire Protection For Major Facilities
Mobile Firefighting Systems Provide Flexible Fire Protection For Major Facilities

A large refinery complex will need to address various hazard mitigation and control problems  Within traditional commercial and industrial firefighting systems, engineers have primarily focused on permanent installation designs rather than entertaining alternative or supplemental mobile firefighting systems. Permanent installation design is typically better understood, supported, and supplied throughout the fire protection engineering and manufacturing community. However, mobile firefighting systems provide unique solutions and advantages compared to their permanent installation cousins such as flexible deployment, simpler servicing, improved economy, and much higher performance availability. The combination of both systems is frequently the most strategic solution for the facility operator. Limitations of fixed installation systems Permanent installation (fixed) systems include everything from sprinklers, foam systems, primary watermain pumps, and the plethora of piping in between. A large refinery complex will need to address various hazard mitigation and control problems that span both hardware and personnel needs. In the event standard hazard mitigation safety procedures and equipment have failed, the facility immediately initiates a hazard control operation. Passive fixed systems automatically engage the hazard through an array of sensors, mechanical triggers, and control algorithms. A properly designed system with adequate hazard coverage, preplanning, preventative maintenance, and testing will successfully terminate the hazard, while firefighting personnel respond and ensure no further hazards develop. This conceptual approach relies on hardware and personnel all operating as planned…. Combining permanent and mobile apparatus “According to plan” would never have any failures or fires, but history has a different script. In the worst-case petrochemical scenario, fixed systems fail to extinguish a hazard putting the entire response on human and mobile hardware resources. This would include but is not limited to firetrucks, mobile high-flow pumping systems, large mobile monitors, foam proportioning units, and large diameter layflat hose. This type of response escalates into a larger scale operation, sometimes involving agencies beyond the facility operator itself. Although a low probability event, the risk to life and property is significantly substantial. Fixed systems may be rendered inoperable due to the loss of electrical power or actual physical damage More typical than the worst-case scenario, facilities experience both maintenance-related system downtimes and natural phenomena damage such as extreme weather and seismic events. In this case, fixed systems may be rendered inoperable due to the loss of electrical power or actual physical damage. Reducing fire-related expenditure In any of these situations, mobile fire apparatus may fill the gap requirements of the facility as their flexible storage and deployment would protect them from everything but the worst natural disasters. Their further benefit is that a smaller set of mobile apparatus resources may be used to protect a larger amount of infrastructure, especially while in use in a mutual-aid program between facilities and communities. According to the NFPA’s report “Total Cost of Fire in the United States”, fire-related damages and expenditures from 1980 to 2014 have risen from roughly $200B (adjusted for inflation to 2014) to nearly $330B. The greatest expenditure is in fire safety costs in building construction, amounting to $57.4B. Although the overall losses per year as a ratio to protection expenditures has dropped by roughly 70% over the past 30 years, petrochemical facility losses have continued to rise over the same time. In the worst-case petrochemical scenario, fixed systems fail to extinguish a hazard  Petrochemical facility challenges According to the NFPA, refineries or natural gas plants had reported an average of 228 fires or explosions per year through the 1990s. Furthering this data with Marsh’s “100 Largest Losses, 25th edition”, refinery losses have continually expanded throughout the last two decades with 11 of the top 20 largest losses of the past 40 years happening during or after the year 2000. Two primary drivers of this trend are the advanced age of petrochemical facilities and their staggering complexity. As oil margins fall, upstream operational businesses are detrimentally affected by reduced investment in everything to new equipment, maintenance and passive safety systems. There is an observable correlation between a major oil price drop followed by upstream facility fire losses. Even with reduced investment and oil throughput growth rates, US refinery utilisation at the end 2017 was at 96.7%, the highest since 2005 (Marsh, The Impact of the Price of Oil). The short story is that systems and personnel are being asked to do more with less with each passing year. Cost-effective mobile apparatus systems  Mobile fire apparatus is generally more cost-effective to procure when using standardised designs and application methodology. They can access open water sources by either drafting (when in close proximity to the water) or using floating source pumps (for variable level or difficult access water sources). Mobile fire apparatus is generally more cost-effective to procure when using standardised designs and application methodology With this open water access, they can provide significantly more water (upwards of 10,000 GPM or more per system if necessary) than any typical fixed fire pumping solution. Moreover, as their primary benefit, they are easy to move and deploy. This benefit allows them to be utilised at the point of hazard as needed while being easily accessible for service. While fixed systems are installed at “every known” hazard and must be continually maintained to operate effectively, mobile systems may be used sitewide or across facilities. This flexibility reduces overall capital expenditure requirements and establishes a valuable primary and secondary firefighting system depending on the hazard and facility resources. Combining fixed and mobile systems Permanent installation fire suppression systems are a mainstay of modern day firefighting. They provide immediate passive response with little human intervention. However, as facility utilisation is pushed to maximum capacity while fixed systems continually age out without adequate replacement or maintenance, mobile systems will need to both fill the response gap and provide a final wall to total loss incidents. The reality is that both fixed and mobile systems need to work together to provide the safest possible operation. Service and training requirements need to also be maintained to manage an adequate, or even better, exemplary response to hazard control incidents. Managing major facility uptime requires continuous oversight and to drive hazard mitigation standards throughout the organisation, including executive management. A safe, reliable and fully-functional plant is also a profitable and cost-effective plant much like a healthy worker is a better worker. Protect your people and property and you will protecting your company’s future.
