Part 1: Scenario-Based Case Study

The course project is a scenario-based case study, which will be due in Unit VIII. A scenario-based case study is similar to other case studies you may have experienced. The scenario-based case study used in this course provides descriptive information and data to help you make decisions as if you were actively participating in a real-life investigation of a warehouse fire. There are eight assignments for the scenario-based case study (one per unit). You will complete and submit Part 1, Sections I and II of the course project in this unit. Use APA level one headings for each section. The heading should be indicative of the major section to follow. Here is a tutorial on level headings.For the course project, you will utilize what you learn throughout the course to solve a real-world problem of what fire protection is needed to create plausible actions, concepts, or inventions to solve fire protection deficiencies that resulted in a large-scale fire in a warehouse distribution center.From Unit I through Unit VII, you will complete one part of your recommendation in each unit, and in Unit VIII, you will write an executive summary and conclusion. You will then compile all parts into one document as your final project. You can arrange each part in any order you would like before submitting the final project. For instance, this assignment about fire pumps is covered in Chapter 6 of the textbook; however, you may choose to cover fire protection, detection, and suppression systems (completed in Unit II) as the first part of your final project and to place fire pumps after another topic of your choice. You are able to organize the final report sections in any order that makes logical sense to you.During each part, you will prepare a well-organized narrative consisting of two sections. Only submit the assignment for that unit until the final case study is compiled from all units and submitted as a single document in Unit VIII. However, you should evaluate and revise the recommendations as needed during the process for each previous unit as you learn more during the progression of this course.This scenario-based case study is designed to draw upon your imagination to think creatively on potential concerns with fire and explosive hazards, fire controls, and fire and emergency management. You should look at fire protection technology in a holistic way. This way of design thinking is significantly different from what was previously designed by thinking in isolation. You will evaluate and develop recommendations to resolve potential fires in the future.Please click  here to view the background information of the scenario.Through the scenario-based case study process, you will begin developing a tool that will synchronize suggestions to improve life safety. You will accomplish this by utilizing recommendations to improve fire protection after a warehouse distribution center fire.Section ISection I will address the foreign-made fire pump and your recommendations after reviewing the background information.Your narrative will consist of your evaluation of the foreign-made fire pump and your choice of fire pump that you would recommend for the rebuild of the warehouse. The background information will provide you the needed material to identify the basic components common to fire protection for the City of Washington Distribution Warehouse. As you review the material, make sure you do the following actions:

  1. examine what contributed to the fire,
  2. analyze building components and existing fire suppression systems, and
  3. prepare and disseminate recommendations.

Fire protection design involves an integrated approach where designers need to analyze the building’s use, occupancy, footprint, and existing fire protection systems or components. This assignment is not looking for compliance with building codes nor expecting you to be a fire protection system designer. However, the purpose of this assignment is for you to apply the concepts and knowledge you learned in this unit as you begin writing your final project covering protection systems that will detect, contain, control, and extinguish a fire. In addition, this assignment provides you with the opportunity to use your skills, expertise, and experience to enrich your response.Section IISection II will address the ethical dilemma of using the foreign-made fire pump, as described in the Points to Ponder Scenario within this unit, as a right versus right action or a right versus wrong action.As we saw in the unit lesson, Kidder (1995) described four basic paradigms that deal with most ethical dilemmas of right versus right choices. He believed ethical decisions often involve choices of the individual versus community, truth versus loyalty, short-term versus long-term, and justice versus mercy. Pick one of the paradigms below, and answer the question.

  • Is it right to use the foreign-made fire pump because others were not available in order to provide fire protection so the warehouse could re-open and the workers could go back to work?  -OR-
  • Do you believe using the fire pump dilemma was a right versus wrong action based on your own values, professional ethics, and institutional values?

For this assignment, you will write a two-page narrative (one page per section) supporting your positions. You must have a title page and references page. An abstract is not required. You may use information from reputable, reliable journal articles, case studies, scholarly papers, and other sources that you feel are pertinent. You should use at least three sources, one of which must be your textbook. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations following proper APA style.

1 Background Information The City Of Washington Distribution Warehouse Fire Introduction The structure wa s a warehouse and distribution facility storing coffee, food commodities, household chemicals , and cleaning products. Originally, the structure stored materials that were classified as non – combustible , and the fire suppression system was designed for non combustible materials. Over time, the warehouse included combustible materials. Construction was rigid steel frame construction wi th reinforced concrete slab floors. The walls we re heavy corrugated metal on the upper part with masonry nonbearing on the bottom. The roof decking wa s corrugated metal panels approximately 1/8 -inch thick, 6 feet wide, and 20 feet long , laid o n top of the rigid steel frames. Offices we re located on the southeast end (Side B) of the structure. The warehouse was renovated in 2015, adding 10,000 square feet of floor space to the north end or Side D . On Side A near Side D (Quadrant 4) we re rectangular unprotected openings used for offloading products at the loading docks. The building is equipped with an automatic wet sprinkler system, fire pump (due to low pressure with the water distribution system) , and a mo nitored fire alarm control unit (FACU). At the time of the fire, the system was in service and activated; however, power to the structure was out for several days due to flooding in the area , causing the loss of the underground primary power supply. Workers were using hand held lights and portable generators to provide light. Because of the poor lighting conditions, a forklift operator ran into a main support of the structure , causing server damage that requir ed arc welders to be on site to repair the damag e. Several of the warehouse workers reported seeing sparks dropping from the welding that ignited nearby cardboard boxes. They also reported that the sprinkler heads in front of the loading dock doors were barely operating , and there were no audible alarms sounding as the fire started. It is believed that poorly operating sprinkler heads w ere the result of low water pressure, because there were multiple heads activated. In addition, the failure of the fire pump to increase pressure was the result of no power. Workers stated that after pulling the manual pull stations , there was no audible alarm. The structure was a Class III non -encapsulated commodity warehouse. Building Conditions – Construction The structure featured rigid steel frame co nstruction (commonly called Butler Construction [red oxide primer finished steel]) and masonry nonbearing exterior walls with poured reinforced tie beams. There was a plywood deck over the main office area that was supported by reinforced concrete walls an d masonry nonbearing exterior walls. Offices were on the southeast end of the first floor; many of them featured drywall partitioning. In the warehouse area, there were multiple rows of 16 -foot high storage racks containing large amounts of coffee products, household chemicals, cooking oil, and paper products that produced a large amount of heat. Rigid steel frame structures all have the inherent qualities and faults associated with steel. The s teel beams quickly absorb ed the heat of the fire below that wa s then transmitted to all of the sheet metal and surface fasteners , causing these materials to become compromised. Previous fire inspections from the City of Washington Fire Department revealed that the fire pump was not completely grounded and bonded properly, and the warehouse needed to implement a program that included preparation, prevention, and recognition of fire hazards. The report also noted that workers needed to be trained on proper handling of combustible and flammable material by segregating and separating them and on maintaining safe housekeeping practices that reduce the risk of fire . In addition, key personnel should have been tra ined in basic fire behavior and suppression. Building Contents 2 The fire load in most areas of the warehouse was very high, due to the nature of the business and the contents in storage with large amounts of cardboard debris. The warehouse contained coffee, food commodities, house hold chemicals , and cleaning products that typically incorporate large quantities of plastics, such as Mylar, cardboard, and other synthetic materials with coffee products inside. These materials burn quickly, produce large quantities of smoke , and have high thermal energy release rates. Many of the products in the warehouse were easily ignited , which supported rapid fire spread below the reach of the sprinkler heads. In addition , the smoke generated during burning gave a dark optical density that impeded visual acuity. Building Fire Protection During renovation of the building, a fire pump was required because the water supply system was not able to provide sufficient pressure to meet the design requirements of the additional square footage. Due to the strict time frame of completing renovations and the unavailability of fire pu mps required for the system , the contractor substituted a foreign -made fire pump. The fire pump complied with foreign regulation s and international codes of practice similar to the National Fire Protection Association (NFPA). In addition, the fire pump met International Organization for Standardization’s ISO 9001: 2008 Quality Management System standards sp ecifically for centrifugal pumps and jockey pumps used in automatic sp rinkler installations. However, the foreign -made fire pump was not Underwriters Laboratories (UL) approved. It is unknown how the fire pump was approved by the authority having jurisdiction. Building Public Water (Potable) Supply System The public water supply system wa s ageing , and deterioration of many of the water mains ha d caused unreliable water needs during the maximum daily consumption demands in the area. The warehouse distribution center was at the end of the water main for the City of Washington controlled by a cross – connection control devic e connected to the City of Greenville public water supply system. However, due to the City of Greenville believing the water quality from Washington would expose their citizens to potentially unsafe water from the failing water mains , they would not agree to open t he cross -connection control until t he City of W ashington would certify water maintenance and operations. Fireground Operations 3 At 1:17 p.m., the fire alarm monitoring company received a report of a water flow alarm at 44614 Mays Street W est and dispatched a first -alarm assignment (three engines, one truck, one rescue, and a battalion chief). The first -arriving company arrived sho rtly thereafter and reported seeing the dense black smoke issuing from the roof area of the Washington Distribution Warehouse. The first due engine companies proceeded to the northeast corner (Side s A and D) of the building and forced open a door that allowed access to part of the loading dock. Crews advancing handlines quickly discovered the fire involved several rows of racks containing various products. A second alarm was called and then several individual pieces of apparatus were called. Side B had minor smoke conditions, with good visibility in the office area. Units found heavy to moderate smoke conditions in the warehouse area causi ng near -zero visibility with mazes of storage racks. Smoke was venting through any opening in the structure. A large amount of cooking oil (56,000 pounds in five – gallon containers [cooking oil weighs between 6 -8 pounds per gallon]) made the fire difficult to extinguish . The oil began to run out of the structure making walking a nd handling equipment even more challenging. Search and rescue operations had to be abandoned because of the size of the structure, visibility, and fire conditions. There was 33,000 square feet of floor area. Although much of the area was open space with storage racks, limited visibility because of the smoke would have complicated search operations , causing search and rescue to be unsafe for the firefighters who assumed no one was inside the structure due to the fire occurring on a Sunday afternoon. 4 After crews mounted an exhausting interior attack using a 3” attack line and several hours of flowing master stream devices , the fire was finally declared under control. Including the fourth -alarm assignment, the total deployment included ten (10) engines, four (4) truck companies, three (3) rescues, three (3) battalion chiefs, the fire chief, and one (1) air supply unit. In addition, logistics personnel and twelve (12) overtime personnel were special -called later that evening for personnel rel ief. Later in the evening , firefighters used a foam solution with moderate success after the main body of the fire was knocked down. Effective Preplanning Although the first -due engine company had been inside the structure on an automatic fire alarm, other companies were unaware of the existing building. There w ere no written preplans or documentation of inspections from the first due engine company . Consequently, once the incident escalated beyond the normal first -alarm assignment, all additional companies had to rely on verbal warnings about hazardous building conditions by radio or face -to-face from personnel assigned to divisions . The automatic fire alarm was March 25, 2009, when a fork lift broke off a sprinkler head and damaged the main support of the building. This fire also illustrated the need to expect the unexpected. Therefore, pre -fire plans must consider the storage area and the width of access points. Pre -fire plans must evaluate the status of sprinkler systems and quick access to key areas of potential fire hazards. These pre -fire plans should account for the tactical priorities information that is applicable to key placement of aerial operations and fire suppression operations. In addition, listing the strategies that a pply to the building, property, and the recognition of any associated hazard would have assisted in the management of this fire. Pre -fire plans provide valuable information that will assist a command officer in managing an incident at a specific property . This information is particularly valuable when the property is large and complex or when an incident could involve unusual risks or hazards to firefighters. Lessons Learned or Reinforced from Building Design Sprinkler Design Must Match the Fire Hazard : • The sprinkler system was a wet system with 8K type heads, 286 0 upright rough brass, 155 0 F rating. The water main was 8” with 40 Static and 1,002 gpm flow at 20 psi residual pressure on January 4, 2014. Design flow requirements varied between 1,240 gpm and 1,376 gpm 5 supplemented by a fire pump meeting certification from BRE Global Ltd., as well as Loss Prevention Standards (LPS) for automatic sprinklers, BS EN 12845, LPC sprinkler rules , and technical bulletins in its LPS 1131. NOTE: The fire pump was not UL approved. • The FACU initiating devices did not sense the presence of the products of combustion and smoke conditions. The spot type heat detector placement was between the steel beams. The designers addressed the beam depth and beam spacing ; however, they did not consider the ceiling height as a factor in placement. • The f ire pump did not increase the pressure and the sprinkler system relied on the existing low pressure reducing water volume to the sprinkler heads. • The sprinkler system protecting the storage of aerosol cans that contained combustible contents, large amounts of cooking oil, plastic bags of coffee products, and cleaning products was at a minimum. These sprinklers were operating above the fire tha t was involving rack storage. This meant the sprinklers only controlled the fire above allowing the fire to spread horizontally from rack to rack. Fire spread was assumed to be contributed from surface flame spread from rack to rack due to the large amount of fuel. • Sprinklers in rack storage placed water directly onto the fire to affect the fire in a variety of ways: immediate extinguishment, some fire control, or even hampering the fire with the continued spread at the floor level. In this fire , the sprink ler system hampered the fire in two ways: 1. The system wa s supplied by the same water main feeding the immediate hydrant system in the area allowing water to be re -allocated from the sprinkler system during fire operations . 2. Large amounts of steam and smoke were produced restricting visibility to interior crews while at the same time allowing the fire to spread at the floor level to other racks. • The f ire pump must be able to supply water to all fire suppression systems , main taining require d pressures that are outlined in NFPA. 6 Warehouse Area Office Area SIDE A SIDE C Side A Warehouse 67,000 Square Feet (63,000 Warehouse / Storage) SIDE B SIDE D 7 Side A Office South East End Warehouse Area Side A Middle Warehouse Area Side A North End Warehouse Area
