DOT Cascade System
An air cascade system serves as bulk storage
of high pressure breathing air to be used to refill breathing apparatus
cylinders used in fire fighting, industry and scuba diving. Cascade
systems can be used in either stationary or mobile applications. They
can be made up of either ASME or DOT storage cylinders. The only
practical pressures used in a cascade system are 3600 - 6000 PSI. Using
2400 PSI storage cylinders is a waste of time and resources. This
results in incomplete SCBA cylinder refills, which is against NIOSH
regulations and places the user in additional danger. The
DOT cylinders must be hydrostatic tested unlike the ASME cylinders. |
