GRADED A+ 100% VERIFIED.
Confined Space ANS >>> 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 ANS >>> An employer's written authorization to perform
work capable of providing a source of ignition.
Inserting ANS >>> 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 ANS >>> 19.5% to 23.5%
Below 19.5=unsafe for breathing
,Above 23.5=explosive
Leader Line ANS >>> 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” ANS >>> 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) ANS >>>
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” ANS >>> Equivalent to a hydraulic volume flow rate; that is the
volumetric quantity of flowing water over time.
Ohm's Law ANS >>> Current through a conductor between two points is
directly proportional to the voltage across the two points.
, S.O.P. ANS >>> Standard operating procedure.
N.E.C. ANS >>> National Electrical Code.
N.F.P.A. ANS >>> National Fire Protection Association
NPT ANS >>> National pipe thread. Tapered pipe.
Compound Gauge ANS >>> Displays negative AND positive pressure
measurements
Cat1 Meter ANS >>> Measures electronics
Cat2 Meter ANS >>> Measures single-phase receptacles.
Cat3 Meter ANS >>> Measures 3 phase distribution and single-phase
lighting equipment.
Cat4 Meter ANS >>> Measures 3 phase at utility connection and any
outdoor connections.
L.O.T.O. ANS >>> Lock out tags out is an Osha regulation.
