Warehouses are normally considered low risk occupancies unless high value or critical components are stored. Some high valve components normally overlooked in warehouses are diamond (industrial grade) studded drill bits or critical process control computer boards. In these cases the economic benefits of installing an automatic sprinkler system should be investigated. [Pg.238]

Means of egress criteria may also rely upon the presence of other building features in the chemical warehouse. Examples include automatic sprinkler systems, fire detection/warning systems (optical flamesensing, smoke, heat, etc.) and smoke removal systems. In certain situations, these systems may permit less restrictive arrangements of the means of egress components. [Pg.73]

Sprinkler system flows are typically calculated to supply water for a duration of 1 or 2 hours. Therefore, a sprinkler system having a combined discharge of 2500 gpm (9500 1pm) over a 1 hour period would produce 150,000 gallons (570,000 liters) of water. If this occurred in a warehouse having a 50,000 ft.2 (4,650 m2) containment area, the depth of water would be 4.8 in. (12.2 cm). (See Table 6-3)... [Pg.74]

The use of draft curtains and automatic heat and smoke vents in sprinklered warehouses is not addressed in NFPA 204M. Fire tests involving various stored commodities using operational sprinkler systems and automatic heat and smoke vents has been limited and inconclusive. [Pg.98]

Sprinkler system design criteria in standards published by the NFPA and FM were developed without the use of draft curtains and automatic heat and smoke vents. FM does not require heat and smoke vent installation. However, FM Loss Prevention Data Sheet 8-9, Storage of Class 1,2, 3, 4, and Plastic Commodities, recommends that heat and smoke vents be manually actuated in sprinklered warehouses, if installed. Conversely, IRI recommends automatic heat and smoke vents in sprinklered buildings except where early-suppression fast-response (ESFR) sprinkler systems are used. [Pg.98]

Powered ventilation systems in chemical warehouses are typically used for some flammable gas and liquid storage areas (see Gas and Vapor Control, Section 6.6). Heating and ventilation systems and powered roof exhaust systems can be arranged to shut down automatically upon receipt of a fire alarm signal so as not to interfere with sprinkler system operations due to airflow. Furthermore, these systems can also be arranged for manual starting and full exhaust by the fire department for smoke removal during search and rescue operations. [Pg.99]

A sprinkler system could have helped put out the fire at the initial stages, or at least cool down the warehouse stmctures. A heat- or smoke-activated chemical foam and fire alarm system could also have been installed in storage places. Materials for cleanup, self-contained breathing apparatus, protective clothing, and portable fire extinguishers should be available on-site. [Pg.800]

Major warehouse fires have occurred even in facilities with automatic sprinkler systems and other built-in fire protection. Problems often are due to lack... [Pg.196]

Wet and dry pipe sprinkler systems are commonly provided to indoor occupancies, such as warehouses, offices, repair shops, inspection shops, etc. They are considered essentially 100% effective for fire suppression if properly maintained and the hazard has not changed since the original design and installation. Sprinkler systems are normally activated by the heat of the fire melting a tension loaded cap at the sprinkler head. The cap melts or falls away releasing water from the pipe distribution network. Thus they do... [Pg.326]

Sprinkler systems are used in offices, laboratories, warehouses, and offshore living quarters. When used offshore, sprinkler systems are normally packed with freshwater to minimize corrosion problems. Saltwater replaces the freshwater during the course of the emergency. [Pg.187]

Mattresses in a 30-foot-high warehouse in Kansas became the cause of a fire because they were stored too close to a mercury vapor light. When the mattresses ignited, the fire activated the heat-detection system and wet-pipe sprinkler system. Firefighters used two 1 %-inch fire hoses to combat the fire, which was brought under control after one hour. Damage to the structure and contents totaled 605,000. [Pg.59]

A fire in the third floor of a paper-storage warehouse in Illinois resulted in a 50 million loss. The building did not contain an automatic detection system, but it did have an automatic sprinkler system. Two firefighters were injured fighting the fire. [Pg.59]

It s obvious that sprinkler systems must be designed to match the hazards they are expected to protect. Ordinary warehouses pose a severe enough challenge for sprinklers without the added challenge of high-hazard commodities such as flammable aerosols. [Pg.61]

Extinguishing a fire in a warehouse can be accomplished by fixed sprinkler systems, fire suppressant systems, or fire extinguishers. The chart in Table 5-1 identifies the fire classifications as well as means of extinguishing. [Pg.61]

The effectiveness of warehouse sprinklers was demonstrated during a February 1998 fire in Lilburn, Georgia. The original warehouse was constructed of brick in 1960 and was fully protected by a sprinkler system. At a later date, a second section was added to the building and was constructed of brick and concrete block. The new section of the warehouse, some 45,000 feet, was not sprinkler equipped. [Pg.67]

When the concrete-block fire wall between the two building sections collapsed, the sprinkler system, now nearly forty years old, was triggered. Fifteen sprinkler heads created a water curtain that protected the structure until firefighters arrived. The loss to the unprotected part of the warehouse totaled 1.2 million. [Pg.67]

Trained fire protection engineers must determine the type of system to install in a warehouse and must also design and supervise the correct installation of the system. The four basic sprinkler systems listed below can be installed individually or in combination with each other Figure 5-4. Sprinkler valves are protected by this barrier made of... [Pg.68]

Many factors must be considered when designing a warehouse storage system. If the wrong choice is made in laying out storage racking, this error can be corrected before operations begin. If the sprinkler system is in error, it may take a fire to reveal the problem. At this point it is too late to correct the error and a serious fire loss may occur. [Pg.73]

The storage and classification of the commodity in the warehouse is also important. Commodities are classified according to how fast they burn and how much heat they release. Plastics, as an example, burn rapidly and release twice the heat of burning wood. A plastics fire can be hot enough to render some sprinkler systems inoperative As fast as the water would flow from a sprinkler head, the water would vaporize. As a result of this problem, sprinkler systems must be designed to accommodate the storage of plastics. [Pg.74]

Flammable liquids in small pressurized spray cans, such as paints, hair sprays, or engine cleaners, have the ability to explode from internal pressure when heated in a fire. The exploding cans create fireballs and are rocketing projectiles that leave a trail of burning liquid. Even a small quantity involved in a warehouse fire can have the potential to spread a fire and overtax the sprinkler system. Figure 5-9 illustrates a poster identifying the dangers of aerosols. [Pg.74]

Sprinkler systems involving aerosols should be specifically designed by a fire protection engineer. In-rack sprinklers may be necessary, along with isolation of the product, fire doors, chain link fences, and special storage cabinets to protect the warehouse fi-om these hazards. [Pg.74]

A two-story general-storage warehouse for a mail-order company in Indiana experienced a 10 million fire on October 8, 1996. The fire started in a second-story supply room. The detection system on the second floor had been disconnected several years earlier. Sprinklers on the first level and in an adjacent structure activated but could not control the fire. [Pg.59]
