ISO 45001
International standard for occupational health and safety management
NERC CIP
Mandatory standards for BES cybersecurity and reliability
Quick Verdict
ISO 45001 provides voluntary OH&S management for all industries globally, emphasizing leadership and continual improvement. NERC CIP mandates cyber-physical security for North American electric utilities, enforced by FERC audits and fines. Organizations adopt ISO 45001 for safety certification; CIP for grid reliability compliance.

ISO 45001 Details
What It Is
ISO 45001:2018 is an international standard for Occupational Health and Safety Management Systems (OHSMS). It provides a framework to prevent work-related injuries and ill health, improve OH&S performance proactively. Built on Annex SL High-Level Structure and PDCA cycle, it emphasizes risk-based thinking.
Key Components
- Clauses 4-10: context, leadership, planning, support, operation, evaluation, improvement.
- Hierarchy of controls, worker participation, management of change.
- No fixed controls; scalable requirements.
- Optional third-party certification via audits.
Why Organizations Use It
- Reduces incidents, legal risks, insurance costs.
- Enhances resilience, culture, supply-chain compliance.
- Integrates with ISO 9001/14001 for efficiency.
- Builds stakeholder trust, competitive edge.
Implementation Overview
- Phased: gap analysis, policy/objectives, controls, audits.
- Applicable to all sizes/sectors; 6-12 months typical.
- Involves training, documented information, management reviews.
NERC CIP Details
What It Is
NERC CIP (North American Electric Reliability Corporation Critical Infrastructure Protection) are mandatory reliability standards for cybersecurity and physical security of the Bulk Electric System (BES). They employ a risk-based, tiered approach, categorizing BES Cyber Systems by high, medium, or low impact to prioritize controls.
Key Components
- Core standards: CIP-002 to CIP-014 covering asset identification, governance, perimeters, system security, incident response, recovery, and supply chain.
- ~45 requirements across domains like patching (35-day cadence), logging (90-day retention), and training (15-month cycles).
- Built on CIP Senior Manager accountability and annual audits.
- Compliance via evidence retention (3 years) and FERC enforcement.
Why Organizations Use It
- Legal mandate for BES owners/operators to avoid multimillion fines.
- Mitigates grid instability risks from cyber threats.
- Enhances resilience, insurance benefits, and stakeholder trust.
- Provides operational efficiency through standardized processes.
Implementation Overview
- Phased: scoping, gap analysis, controls, testing, audits.
- Targets utilities in US/Canada/Mexico; complex IT/OT integration.
- Requires annual audits by NERC/Regional Entities.
