BC Class B Electrical FSR flashcards
BC Class B Electrical FSR · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- BC Electrical Code adoption
- The Canadian Electrical Code Part I is adopted as the BC Electrical Code with local amendments; the edition in force and any municipal bylaws must be confirmed before design or installation.
- Bonding versus grounding
- Bonding connects non-current-carrying metal parts to provide a low-impedance fault path; grounding connects the electrical system to earth. Both are required and serve different purposes.
- Working space clearance
- Clear working space in front of electrical equipment is measured from the live front face and must be permanent, unobstructed, and not used for storage; depth depends on voltage and face condition.
- Box fill calculation
- Box fill counts conductors, device yokes, clamps, and equipment grounding conductors against the box volume allowance for the conductor size, ensuring the box is not overfilled.
- Voltage drop formula
- For a single-phase two-wire circuit, voltage drop equals two times length times conductor resistance per unit length times current; it is a design consideration rather than a strict code limit.
- GFCI protection locations
- Ground-fault circuit interrupter protection is required for receptacles in specified wet, damp, outdoor, and other hazardous locations as set out in the code.
- Panelboard directory requirement
- Panelboards must have a legible directory identifying each circuit; unused openings must be closed and dedicated space above the panel maintained.
- Approved equipment certification
- Electrical equipment must bear a certification mark from a recognized certification body, such as CSA, ULC, or Intertek/ETL, indicating approval for the intended use.
- Arc flash boundary
- The arc flash boundary is the distance at which incident energy equals the threshold for second-degree burns; it is determined by an arc flash risk assessment.
- Limited approach boundary
- The limited approach boundary is a shock protection distance that unqualified persons must not cross; for nominal voltages up to 750 V it is typically 3 m (10 ft).
- Lockout tagout verification
- Lockout/tagout requires isolating all energy sources, applying personal locks, and verifying absence of voltage with a tested meter before work begins.
- Enclosure rating integrity
- Equipment in wet or corrosive locations requires an appropriate enclosure rating, and field modifications must not downgrade that rating.
- Loose termination hazard
- Loose electrical terminations increase resistance and heat, making them a leading cause of electrical fires and equipment failure; thermal inspection helps detect them.
- Safety Standards Act framework
- The Safety Standards Act and Electrical Safety Regulation establish the legal framework for electrical safety in BC, administered by Technical Safety BC and some municipalities.
- Permit before work
- An electrical permit must be obtained before regulated work begins, except for work exempted by regulation; the permit holder is responsible for code compliance.
- Permit non-transferability
- An electrical permit is not transferable; the permit holder must notify the inspection authority when work is ready for inspection and must not cover work prematurely.
- Declaration of completion
- The declaration of completion signals that the installation is ready for final inspection and energization; false or premature declarations can result in enforcement action.
- Compliance order response
- Compliance orders and defect notices must be addressed within the stated time; failure to comply can lead to disconnection of power or further enforcement action.
- Incident reporting to authority
- Electrical incidents causing injury, fire, or significant equipment damage must be reported to the safety authority as required by regulation, with accurate details.
- FSR certification class
- A Field Safety Representative is certified by Technical Safety BC; a Class B FSR is limited in scope compared with Class A and must work within their certified class.
- FSR supervision responsibility
- The FSR ensures electrical work under their authority complies with the code and supervises workers appropriately, with supervision level matched to worker competence and task risk.
- Direct versus indirect supervision
- Direct supervision means the supervisor is present and observing; indirect supervision involves periodic checks. The required level depends on worker qualification and task hazard.
- Apprentice supervision scope
- Apprentices must perform work within their training scope and under supervision appropriate to their competence level and the hazard of the task.
- Near miss reporting
- A near miss should be investigated and documented even without injury, because it identifies hazards before a serious incident occurs.
- Delegation accountability
- Delegating duties does not remove the FSR's responsibility; the FSR remains accountable for work performed under their certification.
- Incident root cause analysis
- Incident investigations should identify root causes, not just immediate causes, and corrective actions should be tracked to completion to prevent recurrence.
- Incident report content
- Incident reports should include date, time, location, persons and equipment involved, a description of the event and response, and corrective actions taken.
- FSR record keeping
- The FSR should maintain records of supervision, inspections, training, and incident reports to demonstrate compliance during audits by the safety authority.
- Hazard assessment before work
- A hazard assessment must be completed before work begins and should consider shock, arc flash, fall, and confined-space hazards relevant to the task.
- Arc-rated PPE requirement
- Personal protective equipment must suit the task; arc-rated clothing and face protection are required where an arc flash risk assessment identifies incident energy exposure.
- Stop work authority
- The FSR must ensure work stops when unsafe conditions are identified and resumes only after hazards are controlled and corrective actions are verified.
- Refusal of unsafe work
- Workers have the right to refuse unsafe work; the FSR should ensure workers know this right and that refusals are handled appropriately without reprisal.
