We have all seen a blower the size of a lunch box attempting to ventilate a 500,000-gallon vessel! The permit calls for a “blower,” so to meet the permit conditions; the team grabs the nearest available blower and NOT necessarily the CORRECT BLOWER! However, on the other side of the argument, most written CS entry programs and training materials do NOT provide the knowledge needed by an entry supervisor to determine the proper size of the blower required for their entry permit.
This “straight-line” tool makes this SIMPLE, FAST, and EASY!!
To use the tool, all one needs is a straight edge, such as a ruler, pen, or even a piece of paper! All anyone needs to know is the SIZE of the space and the size of their blower, and the tool will tell them how long it will take THAT SPECIFIC BLOWER to ventilate THAT SPECIFIC SPACE.
