A space that:
-is large enough to enter and work.
Confined Space -has limited or restricted means for entry.
-is not designed for continuous occupancy.
An employer's written authorization to perform work capable
Hot Work Permit of providing a source of ignition.
A form of purging or ventilating a confined space where an
inert gas (such as nitrogen, carbon dioxide or argon) is used
to displace the atmosphere in a confined space to remove fire
or explosion hazards. Causes oxygen levels to become
Inerting unstable for re-entry.
19.5% to 23.5%
Below 19.5=unsafe for breathing
Oxygen Safe Zone Above 23.5=explosive
The part or area of a drawing to which a number, note or
other reference applies. They are solid lines and usually
Leader Line terminate in a single arrowhead.
Hydraulic Term: A construction in the bore of the pipe which requires more
pressure to pass the same amount of water.
"Resistance"
Electric potential is equivalent to pressure and the voltage (or
Hydraulic Term: voltage drop/potential difference) is the difference in pressure
"Voltage" between two points.
(Assume water is flowing
horizontally so gravity isn't a
factor)
Equivalent to a hydraulic volume flow rate; that is the
Hydraulic Term:
"Current" volumetric quantity of flowing water over time.
Current through a conductor between two points is directly
proportional to the voltage across the two points.

A device used to measure the flow in an open channel. The
flume narrows to a throat of fixed dimensions and then
expands again. The rate of flow can be calculated by
Partial Flume measuring the difference in head (pressure) before and at the
throat of the flume.
