It’s Introduce a Girl to Engineering Day! Check out what one of our engineers has to say about her engineering journey.

How to engage girls in STEM is a hot topic these days.  As a woman-owned and operated business; we feel it is important that we are part of the conversation. In honor of Introduce a Girl to Engineering Day, I recently sat down with one of our engineers to discuss why she chose engineering and what suggestions she has for future engineers.

Nancy Epstein graduated from the University of MO-Rolla, now Missouri University of Science and Technology (S & T) in 2000 with a degree in Mechanical Engineering. She has been part of the AIE team since 2015.

Thanks for sharing your knowledge and passion for engineering, Nancy!

  1. First, can you explain a little about what you do at AIE?   When a developer or civil engineering firm is considering a building project, a sprinkler system is required.  This system usually has water flow and pressure requirements.  I work for a company that does the testing and calculations to determine if there will be sufficient water pressure at the site.  If there is not sufficient water, the project will require a fire pump and/or water tank.  Both items are very expensive and the developer will have to include those numbers in the project budget.   Our first step is to schedule a test with the city water or fire department.  Next, we do some research about the water lines around the site and determine where to test.  I travel to the site and meet with our contact and conduct the test.    When I return to the office, we do more research about the water system, then calculate and compile a report stating what water pressure and flow rate will be available at the site.  That way, the final occupant of the building will have third party confirmation that they will have what they need for fire protection at the end of the project.  
  1. What made you decide to go into engineering? When did you know you wanted to be an engineer?   As a kid I liked finding out how things work and I was obsessed with cars.   More practically, in high school English was not my thing.  I think I knew I wanted to be an engineer as a ninth grader.
  1. What were your favorite classes in grade school and high school?   I really liked science.  I had great HS Physics and Chemistry teachers.  Those were my favorites.  Orchestra was another favorite and I loved to read books.
  1. What was the ratio of women to men in your engineering program? (Assuming there were more men than women, what was that experience like?)   At University of Missouri at Rolla, there were five guys for every girl.  I think the odds were a little worse in Mechanical Engineering.  In one class, I was the only girl.  That’s just the way it was.  Generally, I wasn’t treated any differently at school.  It was good preparation for industry.  On the bright side, it was really easy to find a date.
  1. How many years have you worked in your field?   I have worked in engineering for eighteen years, quality control, manufacturing, and fire protection.
  1. Can you describe your typical day and your favorite thing about your day?   I’ll describe a typical week.  I spend about one day a week traveling and testing, then I spend the remainder of the week in the office doing calculations and research and generating a report from the test results.  I really enjoy traveling and testing outside.  Many of our jobs are in Florida and Texas, and it’s nice to go someplace warm in the winter.

On this Date in History: July 23, 1984

Contributed by Stephanie Lange

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 VegasNashvilleHollywood 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” »

MAC building 2
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” »

Annual Fire Inspection Preparation Tips

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

The Importance of Fire System Inspection and Documentation

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 Services

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.

Water Supplies for Fire Protection Service, Part 1

By Chad Lueders, P.E.

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” »
