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)
Confined space:
pitts and vaults
Permit Required confined space:
Hoppers, Steam pipe area, and Chemical Pitt
less than 19.5 % is considered oxygen deficient
6% difficulty breathing (Death in minutes)
14% Faulty judgement (Rapid fatigue)
16% Impaired judgement and breathing
21% normal
Hazardous vapors - blindness, burns, death, and sickness
Liquid chemicals - blindness, burns, death, and sickness
Potentially infectious materials - blindness, death, and sickness
Flying Debris - blindness, death, and sickness
Molten metal - blindness, burns, and death
Fire needs fuel, oxygen, and heat
Class A (green) - wood, paper, cloth, and ordinary trash
Class B (red) - gasoline, oils, paints, and propane
Class C (blue) - electrical fire
Class D (yellow) - magnesium and titanium
Class K (black) - cooking oils, animal and vegetable fats, and grease
Fire extinguisher maintenance:
-inspect (monthly)
-get professional to inspect or test annually
-undergo maintenance every 3, 6, and 12 years
-undergo hydrostatic testing every 6 years (ABC extinguisher is every 12 years)
Apply appropriate supplier labels to controlled products and all containers of controlled products, except when:
-intended for export
-shipment in bulk
-product is imported for the purpose of labelling or repackaging
-controlled products are distributed in multi container shipments.
Physical hazard - based on the physical or chemical properties of the product - such as flammability, reactivity, or corrosivity to metals.
Health hazards - based on the ability of the product to cause a health effect - such as eye irritation, respiratory sensitization (may cause allergy or asthma symptoms or breathing difficulties if inhaled), or carcinogenicity (may cause cancer).
