Pre-job briefing
Document the Job Briefing Before Work Begins
OSHA 29 CFR 1910.269(c) requires the employee in charge to conduct a job briefing with employees before work begins and when significant changes occur that could affect employee safety. MinMax eSMART’s Job Briefing Module provides utilities with a centralized way to document those briefings, capture job-specific safety information, and maintain an accessible record of what was reviewed with the crew.
What the job briefing captures
- 1
Job Hazards
Document hazards associated with the work being performed and conditions at the job site.
- 2
Work Procedures
Record the procedures and work activities discussed with the crew before work begins.
- 3
Special Precautions
Capture additional precautions required because of the job, location, equipment, or changing conditions.
- 4
Energy Source Controls
Document applicable energy-source controls, clearances, tags, grounds, and other safety measures.
- 5
Personal Protective Equipment
Record the PPE requirements reviewed with employees for the work being performed.
How MinMax eSMART simplifies job briefings
- Create standardized electronic Job Briefing forms so crews follow a consistent process across the organization.
- Complete and document briefings in the field, keeping important safety information connected to the work being performed.
- Capture comments, supporting information, and job-specific details within the Job Briefing record.
- Maintain a centralized history of completed Job Briefings instead of relying on individual paper forms.
- Create a new or updated Job Briefing when job conditions or hazards change, helping document that the crew was re-briefed.
- Quickly retrieve historical Job Briefing records for internal reviews, safety documentation, and compliance support.
Cloud-Based Job Briefings Maximize Safety

The core principle
Maintenance only counts if you can evidence it.
PRC-005-6 requires every Generator Owner, Transmission Owner, and Distribution Provider on the Bulk Electric System to run a documented Protection System Maintenance Program — and to produce dated records proving each activity happened inside its maximum interval. NERC leaves the how to the utility; the evidence is what gets audited.
Where PRC-005-6 sits
FERC delegates to NERC, which delegates monitoring to six Regional Entities. Protection & Control (PRC) is one of fourteen mandatory Standards subject to enforcement — PRC-005-6 is one of twenty within it, and it is the one that governs Protection System maintenance.
What falls under it
All three functional entities carry the same R1–R5 obligations. The scope splits into three families of Components — every discrete piece of equipment inside them needs a maintenance record.
5 Component Types
Protection System
- Protective relays
- Communications systems
- Voltage & current sensing devices
- Station dc supply
- Control circuitry
4 Component Types
Automatic Reclosing
- Reclosing relay
- Supervisory relays or functions
- Associated voltage sensing devices
- Control circuitry
2 Component Types
Sudden Pressure Relaying
- Fault pressure relay
- Associated control circuitry
A maintenance program for a Component is one or more of these five activities:
Building a PSMP that holds up under audit
Five requirements, each with a matching measure that defines the evidence you must be able to hand an auditor.
- 1
R1 — Establish the program
Declare a maintenance method for every Component Type — time-based, performance-based, or a combination — and state which monitoring attributes you rely on to extend intervals.
M1 evidence: the current dated PSMP, plus documentation of the method applied to each Component Type.
- 2
R2 — Justify performance-based intervals
If any interval is performance-based, follow the procedure in PRC-005-6 Attachment A to establish and maintain it.
M2 evidence: Component lists, dated maintenance records, and dated analysis records and results.
- 3
R3 — Hold the time-based intervals
Perform at least the minimum activities within the maximum intervals set by Tables 1-1 through 1-5, Table 2, Table 3, Tables 4-1 through 4-3, and Table 5.
M3 evidence: dated maintenance records, summaries, check-off lists, inspection records, or work orders.
- 4
R4 — Implement the performance-based program
Actually run the program you justified under R2, for every Component inside it.
M4 evidence: the same dated records as R3, covering the performance-based population.
- 5
R5 — Chase down unresolved issues
A deficiency that can't be corrected inside the maintenance interval becomes an Unresolved Maintenance Issue — and you must show continuing effort to close it. M5 evidence can include:
- Corrective work orders
- Replacement Component orders and invoices
- Budget approval requests and approvals
- Project schedules with completed milestones
- Return material authorizations and purchase orders
Worked example — choosing a maintenance method
Most utilities start here
Time-based
Fixed maximum intervals straight from the PRC-005-6 tables. Monitoring attributes can stretch an interval, but only where the tables allow it.
Always time-based
Station dc supply batteries
Earned with data
Performance-based
Intervals derived from your own fleet performance under Attachment A, tracked by Segment and reassessed against Countable Events.

Evidence retention — what an audit will ask for
Set by the CEAThe Compliance Enforcement Authority — NERC or your Regional Entity — sets how far back you must be able to reach. Retention is keyed to the audit cycle, not the calendar.
- R1 — the current dated PSMP plus every superseded version since the preceding compliance audit.
- R2–R4 — where the interval runs longer than the audit cycle, the most recent performance; where it runs shorter, every performance since the last scheduled audit date.
- R5 — all Unresolved Maintenance Issues raised since the last audit, including the ones already closed.
- How it gets checked — Compliance Audits, Self-Certifications, Spot Checking, and Compliance Investigations.
The core principle
A facility is only as strong as its most limiting element.
FAC-008-3 requires every Transmission Owner and Generator Owner to rate a facility by its weakest component — not its average, not its newest part. Under the current version you also identify the next most limiting element and account for impaired equipment as an operating limit.
Where FAC-008-3 sits
FERC delegates to NERC, which delegates monitoring to six Regional Entities. The Transmission & Generator Owners running the grid answer to whichever standards apply — FAC-008-3 governs Facility Ratings.
What it requires
Normal and Emergency ratings must respect the most limiting equipment. Where the documentation obligation falls depends on who owns what.
Requirement 1
Generator-side facility
Documentation up to the boundary set by who owns the main step-up transformer (GSU).
Owner: Generator Owner
Requirement 2
Generator Ratings Methodology
A methodology from the R1 boundary to the point of interconnection with the Transmission Owner.
Owner: Generator Owner
Requirement 3
Transmission facilities
A methodology for every solely and jointly owned Transmission facility outside R1/R2.
Owner: Transmission Owner
Building an FRM that holds up under audit
- 1
Document ambient conditions
Every element needs an FRM entry showing how ambient conditions were considered — matching the actual region the facility operates in.
- 2
Split ratings by season, if conditions vary
Keep separate summer and winter rating sets — each with its own Normal and Emergency rating.
- 3
Ground it in a technical foundation
Every rating needs a paper trail:
- Manufacturer rating for each element
- Nameplate photos
- Calculations used to determine element ratings
- Applicable industry ratings
- Engineering drawings
- 4
Maintain the rating chain per facility
Identify each element's rating, then the most- and next-most-limiting element as seen by each owner — and the overall pair that sets the facility's Normal and Emergency ratings.

FERC Order 881 — Ambient Adjusted Ratings
Effective Jul 12, 2025Where FAC-008-3 governs facility ratings broadly, Order 881 targets transmission lines — replacing fixed Static Ratings with ratings that respond to real-time ambient temperature (and, for Dynamic Line Ratings, wind and solar too).
- Ambient Adjusted Ratings — required for near-term service requests and lines affected by air temperature.
- Hourly updates — RTOs and ISOs must support ratings that update at least hourly.
- Emergency ratings — uniquely determined emergency ratings for contingency analysis.
- Transparency — ratings and methodologies shared with providers, RTOs/ISOs, and posted on OASIS.
