Nice information to help clients:

Why use a rectangular tank intead of a cylindrical tank?

  • Increased Capacity: rectangular tanks use the maximum space available, for the same floor space (footprint) rectangular tanks will offer 25-30% more capacity than cylindrical tanks.
  • Cost-effective Shipping: rectangular tanks are smaller than cylindrical tanks for comparable capacities, this decreases their shipping size/weight. They are also flat bottomed/topped making them stackable during shipping (size permitting) and eliminating the need for special attention to securing them onto the transport with saddles and during loading/unloading.
  • Skid/Platform Integration: rectangular tanks can be skided very easily and offer superior packaging configurations for full pumping units to be integrated onto the tank skid. They also eliminate the need for platforms to access the fittings up top.
  • Advertising: larger rectangular tanks offer prime real estate for advertisment billboards on job sites and chemical plants with their flat exposed faces.

For Canada: What are flammable and combustible liquids?

Flammable and combustible liquids are liquids that can burn. They are classified, or grouped, as either flammable or combustible by their flashpoints. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily at normal working temperatures. Combustible liquids have the ability to burn at temperatures that are usually above working temperatures. There are several specific technical criteria and test methods for identifying flammable and combustible liquids. Under the Workplace Hazardous Materials Information System (WHMIS), flammable liquids have a flashpoint below 37.8°C (100°F). Combustible liquids have a flashpoint at or above 37.8°C (100°F) and below 93.3°C (200°F). Flammable and combustible liquids are present in almost every workplace. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and polishes may be flammable or combustible liquids. Everyone who works with these liquids must be aware of their hazards and how to work safely with them.
