(Horizontal) attached harness and lanyard does not need (CSA) approval.
- less than 4 workers at a time
-3/4 inch diameter wire rope
-6 feet away from edge lanyard from edge
(Vertical) attached harness and lanyard must be (CSA) approved.
-could be synthetic or wired rope
Double choker sling
(hang on anchor)
Parameters of extra low voltage to high voltage
Fall restraint
falling over edge
(PASS) stands for?
Point, Aim, Squeeze, and Sweep
Combustible metals?
Aluminum, Magnesium, and Titanium
Identify Knot?
Air to Gas Ratio = ____
Range to ignite (Upper and Lower Limit)
Arc Faults detect base on:
-current for magnitude
-duration
-length of time between pulses
* not for particular waveform
Personal injury or Death
payable first work day after injury occurred unless:
-unless serious or willful misconduct of the worker
-unless death
-aggravate injury
Employee
must report any unsafe regulation or hazard
must have supervisor or foremen
Owner’s of Property
make sure workplace is safe to premise
Supplier’s
supply safe condition
-labelled (WHMIS) (SDS)
Work Report - as soon as possible & employer or board (workplace BC)
-immediate any death
-3 days notify board
Parallel Arc Fault - limited by resistance of the conductors in the circuit & not by the load
(continuous current) - typically much higher current - but for thermomagnetic circuit breaker
(intermittent short) - takes time to heat up - especially small conductors
Tool box talks - quick review meeting before start of work to bring up or mitigate hazards
Ground fault - path to ground other than intended path is established
Fire Retardent clothing
a typical motor-control centre - produce enough energy during an arc flash to kill a person 9 meters away
-especially crucial for maintenance with high power sources (transformers installations & motor-control centre)

pitts and vaults
Permit Required confined space:
Hoppers, Steam pipe area, and Chemical Pitt
less than 19.5 % is considered oxygen deficient
