Q

Work Report - as soon as possible & employer or board (workplace BC)

-immediate any death
-3 days notify board

18
Q

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

19
Q

Tool box talks - quick review meeting before start of work to bring up or mitigate hazards

20
Q

Ground fault - path to ground other than intended path is established

21
Q

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)

22
Q

Confined space:

A

pitts and vaults

23
Q

Permit Required confined space:

A

Hoppers, Steam pipe area, and Chemical Pitt

24
Q

less than 19.5 % is considered oxygen deficient

25
6% difficulty breathing (Death in minutes) 14% Faulty judgement (Rapid fatigue) 16% Impaired judgement and breathing 21% normal
26
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
27
Fire needs fuel, oxygen, and heat
28
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
29
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)
30
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.
31
Physical hazard - based on the physical or chemical properties of the product - such as flammability, reactivity, or corrosivity to metals.
32
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).
33
Hazard Categories High - 1 to 1A to 1B to 1c Low - 3A to 3B to 3C to 4
34
Products (Completely) Exempted from WHMIS legislation: - Wood and products made of wood - Tobacco and tobacco products - Manufactures articles - Products being transported or handed under TDG legislations
35
Products (Partially) Exempted from WHMIS legislation: - Radioactive Materials - Consumer Products - Cosmetics, Medical Devices, Food, Drugs - Explosives - Pesticides
36
WHMIS Pictograms: Physical Hazards: Gas cylinder Flame Flame over circle Corrosion Exploding bomb Health Hazards: Skull and Crossbones Exclamation Mark Biohazardous infectious materials Health hazard Environment: Environment
37
Two type of labels: Supplier and Workplace labels
38
Safety Data Sheet (SDS) - provide information on safety precautions Sec 1 - Identification Sec 2 - Hazard identification Sec 3 - Composition/Information on ingredients Sec 4 - First Aid Sec 5 - Fire fighting measures Sec 6 - Accidental release measures Sec 7 - Handling and Storage Sec 8 - Exposure controls/Personal protection Sec 9 - Physical and Chemical properties Sec 10 - Stability and reactivity Sec 11 - Toxicology information Sec 12 to 16 - Optional Sec 12 - Ecological information Sec 13 - Disposal considerations Sec 14 - Transport information Sec 15 - Regulatory information Sec 16 - Other information
39
Routes of entry through body from Exposure: Inhalation (common) Skin/Eye contact Ingestion Injection (least common) Acute (immediate) Chronic (long term or prolonged)
40
Hierarchy of controls: - Most Effective to... Elimination (physically remove the hazard) - ____ (replace the hazard) - _____ (isolate people from the hazard) - _____ (change the way people work) - ____ (protect the worker with personal protective equipment) - ... Least Effective
- Substitution (replace the hazard) - Engineering controls (isolate people from the hazard) - Administrative controls (change the way people work) - PPE (protect the worker with personal protective equipment)
