National Fire Prevention Week 2019

Since 1922, the National Fire Protection Agency, also known as NFPA, has sponsored the national public observance of Fire Prevention Week during the week of October 9th, in commemoration of the Great Chicago Fire of 1871. As the longest-running public health observance in the United States, Fire Prevention Week aims to educate people of all ages on how to stay safe in the case of a fire, in an effort to drastically decrease the number of casualties caused by fires.

For Fire Prevention Week 2019, the campaign chosen by the NFPA is “Not Every Hero Wears a Cape. Plan and Practice Your Escape!” This campaign works to educate everyone about the small yet important actions each of us can take to keep both ourselves and those around us safe during a fire. Split second decisions can make all the difference on whether or not a safe escape is possible. In recent years, we’ve seen the possible devastation caused by fires to our wildland areas, our communities, and neighbors. This is why educational resources and related teachings during Fire Prevention Week are so critical to the safety of our communities, because not only do they prepare us for the incident but they give us the insight needed to make the right decision and react promptly under these dire circumstances.

For us at Superior Tank, the fire protection industry serves as one of our largest and most important markets. Every year, we ship hundreds of bolted and welded fire protection steel storage tanks from our manufacturing facilities to customers around the world, as part of both small- and large-scale projects designed to suppress fires. Our fire protection storage tanks are designed to meet the specifications of any fire suppression, fire sprinkler, building, or wildland fire protection project. Backed with decades of knowledge and experience, Superior Tank has the ability to provide both NFPA compliant and FM Approved certified storage tanks, giving you the peace of mind needed when dealing with stringent specifications and agency inspections.

We are committed to providing each customer with a quality storage fire protection tank prepared to operate consistently at a high performing level to ensure the safety of their facility and employees. As described by the NFPA, A hero can also be…someone who takes small, but important actions to keep themselves and those around them safe from fire.” We only hope that our storage tanks can act as that important action designed keep each and every one our customers fully prepared and safe from any and all fire threats.

Protecting a Precious Resource

water week 2019

Drinking Water is the essence of life and Superior Tank is proud to support the 2019 AWWA Drinking Water Week! Drinking Water Week was conceived over 40 years ago by the American Water Works Association (AWWA) to promote the vital role drinking water has in our lives. Only 1% of the water on earth is suitable to drink and without water a human can only survive 4-7 days. Drinking Water Week highlights the need to reduce water consumption and protect the various sources of drinking water including lakes, underground aquifers and rivers. Here are some basic ways you can make an impact!

  • Turning off the water when brushing your teeth saves up to 4 gallons of water.
  • Taking shorter showers as 10-minute shower can use 20 gallons of water!
  • 30% of total water consumption is outdoor use and only watering landscape when needed can reduce this percentage 0% of total water consumption is outdoor use and only watering landscape
  • Fixing running / leaking toilets can save 200 gallons per day
  • Use a hose with automatic shut off nozzle when washing your car or take to automatic car wash which recycles water
  • Upgrade to water efficient dishwashers and clothes washers: ask your local water agency if rebates are available!
  • Soak up any outdoor oil spills with absorbent then discard into trash
  • Repair cars with fluid leaks to avoid storm water contamination
Superior Tank is privileged to play a role in storing the precious resource of drinking water. Our bolted and welded steel water tanks are a key element in the drinking water distribution infrastructure, ensuring millions of people around the world can store drinking water in a secure and sanitary manner. Our storage tanks are second to none in quality and meet or exceed the worldwide accepted standards for potable water storage set by the AWWA such as the D100 and D103. In addition, we can provide bolted steel tanks with NSF 61/372 Certification for drinking water storage. Our powder coating system is one of the most environmentally friendly coatings available! We utilize an NSF Certified epoxy powder coating on the interior of our bolted tanks for potable water storage. Additionally, our application process reduces water consumption as it does not use water as the powder coating is applied dry in our production facility. Connect with us via social media for other ways you can help Protect the Source!

Changes to ladder safety requirements have arrived!

The Federal OSHA Occupational Safety and Health Standards requirements for fall protection on fixed ladders were revised in October of 2016 with some new requirements becoming effective after November 19, 2018. This revision relates to all ladders including those installed on bolted and welded steel ground storage tanks. All new ladders installed after November 19, 2018 extending over 24’ above a lower level must include a ladder safety or personal fall arrest system. Existing ladders, defined as ladders installed before November 19, 2018 must be equipped with one of the following items: ladder cage, ladder safety system or personal fall arrest system. All new ladders installed after November 19, 2018 will not be able to use a ladder cage as the exclusive fall protection method. Ladder cages will still be able to be used provided they are combined with a primary fall protection method such as a ladder safety or fall arrest system and the cage does not interfere with the primary system. After November, 19, 2036 all existing ladders not in compliance with the requirements for new ladders will need to be retrofitted to have either a ladder safety or personal fall arrest system.

A ladder safety system is designed to eliminate the possibility of your employees falling from the ladder. Similarly, a fall arrest system stops the fall before the worker impacts the surface below.

Ladder Safety Systems Commonly Includes

  • Lanyard
  • Connectors
  • Body harness
  • Carrier
  • Safety sleeve

Fall Arrest Systems Commonly Includes

  • Lanyard
  • Connectors
  • Body harness
  • Positioning system
  • Travel restraint system/deacceleration device

Ladder Cages Commonly Includes

  • Enclosure surrounding climbing space of ladder
For all new and existing fixed ladders with heights less than 24’ above a lower level, no fall protection is required by OSHA but ladder cages, ladder safety systems, or fall arrest systems can be used if desired.

New Ladders (installed after 11/19/18)>24′YesO ²MM
All Ladders after 11/19/36>24′YesO ²MM
All Ladders≤ 24′NoOOO
O = Optional, Not Required M = Meets OSHA Requirement ¹ Only 1 of the acceptable fall protection methods is needed to satisfy OSHA requirements ² Cannot be used exclusively, Must be combined with Ladder Safety System or Fall Arrest System

Another change in the regulation is the requirement of resting platforms. After November 19, resting platforms are required at maximum 50’ intervals when a cage is used and 150’ maximum intervals when a personal fall arrest or ladder safety system is used. Under the old regulation the maximum distance was only 30’ for each segment and if a safety device was used on a ladder for tower, water tank or chimney, a platform was not required at all.

In addition to ladder systems, Superior Tank offers other equipment to keep your workers safe while working with ground storage tanks. For example, tie-points at various locations on the tank such as around the roof hatch provide a suitable anchor for fall protection systems. Also, extending roof railing and installing OSHA required self-closing gates at openings can also prevent worker falls.

Please note, your local regulations may differ as select areas have regulations independent of Federal OSHA Requirements.  Our safety experts can recommend the right equipment to prevent injuries to your workers and comply with OSHA requirements to avoid fines and penalties.

ASCE 7 Update and the Impact on Bolted Tanks

The latest edition of the American Society of Civil Engineering (ASCE) 7-16 Standard for Minimum Design Loads and Associated Criteria for Building and Other Structures published in August 2017, includes an exception to the AWWA D103.  Section relating to bolted steel tanks, includes new requirements regarding bolted tanks with an embedded steel base setting ring:

  • “b. For Type 6 tanks, the overturning ratio, J, as determined using AWWA D103, Eq. (14-32) shall not exceed 0.785.” This new verbiage has significance to bolted tank design as it impacts where a bolted tank with a Type 6 foundation can be used.

A Type 6 bolted steel tank utilizes a steel base ring shell embedded into the concrete foundation which also serves as the tank bottom.  The J ratio relates to the seismic loading and is a criteria used to determine if the storage tank requires anchorage.  A value of less than 0.785 indicates the tank wall will not experience uplift and does not need anchorage. Conversely, a J ratio greater than 1.54 requires the bolted tank to be mechanically anchored. Ratios between the two values may or may not require mechanical anchorage depending on other factors.


Essentially, the ASCE is requiring embedded shell bolted steel tanks not to be used in areas where uplift occurs due to seismic activity. The concern is there are no specific design requirements for  the anchorage of the shell to foundation and the concrete bottom included in the AWWA D103 therefore it is difficult to ensure ductility of the tank to foundation connection. There is a risk of the shell separating from concrete tank bottom during a seismic event as a design criteria does not exist to ensure the connection is properly designed. ASCE 7-16 does not restrict bolted tanks with other foundation types; only tanks with an embedded shell.


For most applications, Superior Tank Co., Inc. will design our bolted tanks to use foundation types 1 through 5. With foundation types 1 through 5, the storage tank will include a steel bottom which structurally ties into the bolted tank shell creating one uniform structure.


This new terminology is another example of how bolted tank standards are continuously evolving resulting in more resilient bolted steel tanks.
