Confined Space - (ANSWER)A space that:
-is large enough to enter and work.
-has limited or restricted means for entry.
-is not designed for continuous occupancy.
Hot Work Permit - (ANSWER)An employer's written authorization to perform
work capable of providing a source of ignition.
Inerting - (ANSWER)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 unstable for re-entry.
Oxygen Safe Zone - (ANSWER)19.5% to 23.5%
Below 19.5=unsafe for breathing
Above 23.5=explosive
,2
Leader Line - (ANSWER)The part or area of a drawing to which a number, note or
other reference applies. They are solid lines and usually terminate in a single
arrowhead.
Hydraulic Term:
"Resistance" - (ANSWER)A construction in the bore of the pipe which requires
more pressure to pass the same amount of water.
Hydraulic Term:
"Voltage"
(Assume water is flowing horizontally so gravity isn't a factor) - (ANSWER)Electric
potential is equivalent to pressure and the voltage (or voltage drop/potential
difference) is the difference in pressure between two points.
Hydraulic Term:
"Current" - (ANSWER)Equivalent to a hydraulic volume flow rate; that is the
volumetric quantity of flowing water over time.
Ohm's Law - (ANSWER)Current through a conductor between two points is
directly proportional to the voltage across the two points.
S.O.P. - (ANSWER)Standard operating procedure.
N.E.C. - (ANSWER)National Electrical Code.
, 3
N.F.P.A. - (ANSWER)National Fire Protection Association
NPT - (ANSWER)National pipe thread. Tapered pipe.
Compound Gauge - (ANSWER)Displays negative AND positive pressure
measurements
Cat1 Meter - (ANSWER)Measures electronics
Cat2 Meter - (ANSWER)Measures single-phase receptacles.
Cat3 Meter - (ANSWER)Measures 3 phase distribution and single phase lighting
equipment.
Cat4 Meter - (ANSWER)Measures 3 phase at utility connection and any outdoor
connections.
L.O.T.O. - (ANSWER)Lock out tag out is an osha regulation.
3 elements needed to start a fire. - (ANSWER)Heat, oxygen and fuel.
Class C fire. - (ANSWER)Electrical fire
