It has been 11 years since the day nearby residents say they “felt the ground shake.” Seventeen people were killed in what is still considered the nation’s second worst oil refinery disaster. On July 23, 1984, the Union Oil Company Refinery experienced an explosion that sent a 34-ton tower flying into a small field just beyond nearby houses. Around 6 p.m, a worker had noticed a hairline crack in a high pressure tower with gas vapors escaping from it. The worker tried to shut the tank down, but the vapors ignited from an unknown source before he was successful.
Consequently, much of the refinery was engulfed in flames. A second explosion Continue reading “On this Date in History: July 23, 1984” »

The Role of MIC in Fire Sprinkler System Corrosion
You may have heard the term “MIC” used in reference to corrosion problems in fire sprinkler systems, as it has become synonymous with all general corrosion activity in sprinkler systems. MIC, which stands for microbiologically influenced corrosion, is a very specific type of corrosion caused by bacteria. Over the past several years many practitioners in the fire sprinkler industry have over-emphasized the role that bacteria play in causing corrosion in a fire sprinkler system while under-emphasizing the predominant role that oxygen plays in the corrosion that occurs in these systems.

The Beverly Hills Supper Club fire in Southgate, Kentucky, occurred May 28, 1977, during Memorial Day weekend. A total of 165 people died and over 200 were injured as a result of the blaze. It is the third deadliest nightclub fire in U.S. history. Ten miles outside Cincinnati, the Beverly Hills Club was a major attraction that drew talent from Las Vegas, Nashville, Hollywood and New York, among other places. A popular nightspot and illegal gambling house as early as 1926; Dean Martin, an Ohio native, was even a blackjack dealer there. It was considered an elegant, upscale venue attracting talent and high-class patrons. Continue reading “On this Date in History: May 28, 1977” »
101 Years Ago Today
Today marks 101 years since the deadliest fire in our hometown city, St. Louis. The quick-spreading fire killed 30 men and destroyed the seven-story Boatmen’s Bank building at Washington Avenue and Fourth Street. Boatmen’s Bank built the building in 1890 and had offices on the first floor. The rest of the building was occupied by the Missouri Athletic Club (MAC), founded in 1903. The men’s club remodeled to house dining and meeting spaces, a gym and swimming pool, a Turkish bath, barber shop, bar, and an area of small sleeping rooms, all made of wood, for 97 members and guests on the fifth and sixth floors. Most of the victims of the fire were trapped there or died trying to escape. About 90 members, guests, and employees were in the building at the time of the fire, though the desk registry was destroyed so no one can be sure.

One Meridian Plaza Fire
Three Philadelphia firefighters lost their lives fighting the largest high-rise office building fire in modern American history at the Meridian Bank Building, also known as One Meridian Plaza. Twenty-four additional firefighters were injured. The fire extended from the 22nd up to the 30th floor, with an estimated $100 million in direct property damage. Twelve-alarms brought 51 engine companies and over 300 firefighters to the scene.
Construction on the 38-story Meridian Bank Building began in 1968 and was completed for occupancy in 1973. The building’s fire protection systems was upgraded around 1988. Manual pull fire alarms were replaced by automatic central station monitored alarms. The originally installed dry standpipe system was replaced with a wet system that was fed by Continue reading “On this Date in History: February 23, 1991” »
The purpose of fire inspections is to evaluate and minimize the risk of fires. In general, routine inspections are conducted on commercial, industrial, and apartment buildings to ensure that the appropriate fire safety requirements are being met. These inspections are vital for public safety. Fire inspectors usually inspect for some of the following:
- Alarm systems
- Sprinkler systems
- Fire extinguishers
- Building design and construction
- Fire emergency procedures and evacuation plans

Fire systems can be found in nearly every building because they are required in standard building codes. However, fire systems are not something that can be installed and then forgotten about. For example, fire sprinkler systems must have inspections, tests, and maintenance documented at least once per year and sometimes more often. Failing to do so could result in citations, fines, or an uncontrolled fire emergency.
Importance of Fire System Inspections
Periodic fire system inspections are important because they ensure safety by making sure the fire system would work properly during a fire emergency. There are fire sprinkler system inspection standards published by the National Fire Protection Association (NFPA) for building owners to reference. Many of their standards are recognized by the industry and used by local authorities to evaluate fire system installation, inspections, and tests.

Fire protection engineering is the combination of principals and practices that aim to predict fire hazards and protect property against the possible damages caused by fire. Fire engineering can be provided through many different services.
- Design Services- In the preliminary stages, fire protection engineering would include design services for fire protection solutions based on a risk and hazard analysis, code consultation, and hydraulic analysis.
- Fire Hazard Assessments- Fire protection engineering involves evaluating whether there are fire hazards, what the risk of a fire is, and measuring what damages a fire would cause. This evaluation can be done using a hazard analysis.

The vast majority of fire protection systems utilized in buildings today rely partially or completely on the municipal water system to provide the water necessary to control or suppress the fire. While seemingly only a small part of the overall fire protection system, an understanding of how municipal water systems are operated, and what their limitations are, is vital to ensuring a reliable and functional fire protection system.
At the most basic level, water departments typically maintain their system pressure or hydraulic grade in one of two ways.
The first, and probably most common, is with an elevated storage tank(s), commonly referred to as a water tower. With this arrangement the water system “floats” on the level Continue reading “Water Supplies for Fire Protection Service, Part 1” »
Most people think that fire sprinkler systems are triggered by small amounts of smoke, but in fact, fire sprinkler systems are set off by intense heat, one sprinkler head at a time. Fire sprinkler systems have been designed to use the minimum amount of water required to do the job, saving you from costly water damage as well as the fire damage they are designed to stop.
Huge improvements have been made in fire sprinkler systems over the last 200 years. Early versions caused severe water damage, but modern fire sprinkler systems have reduced loss of property and deaths by a whopping 65%. Since each sprinkler head is triggered separately by a specific temperature, one or two sprinklers can contain a fire to the room where it started, minimizing property damage. Fire hoses use six times more Continue reading “How to Choose a Fire Sprinkler System” »
