Standard Operating Procedure: Hazard Register Implementation for NZ

Standard Operating Procedure: Hazard Register Implementation (NZ/AS/NZS ISO 45001)

---

1. Executive Summary & Purpose

This document provides the standardized framework for the creation and maintenance of a Hazard Register within New Zealand-based operations. The purpose is to ensure compliance with the Health and Safety at Work Act 2015 (HSWA) by systematically identifying, assessing, and controlling risks to workers and other persons.

2. Scope & Prerequisites

• Scope: All operational sites, corporate offices, and off-site project locations under the entity’s remit.
• Software Requirements: Template Registry Approved Digital Risk Management Platform (or ISO-compliant Excel/G-Sheet template).
• Regulatory Context: Aligned with WorkSafe NZ Guidelines and AS/NZS ISO 31000 (Risk Management).

3. Roles & Responsibilities (RACI Matrix)

4. Step-by-Step Procedure

Phase I: Hazard Identification

• Conduct physical site walkthroughs and task analysis.
• Review historical incident/near-miss logs.
• Solicit feedback from site personnel regarding "hidden" operational risks.

Phase II: Risk Assessment

• Assign a Likelihood (1-5) and Consequence (1-5) score to each hazard.
• Calculate Risk Rating (Likelihood × Consequence = Risk Score).
• Categorize into: Low (1-4), Medium (5-9), High (10-16), Critical (17-25).

Phase III: Control Implementation (Hierarchy of Controls)

• Elimination: Can the hazard be removed entirely?
• Substitution: Can a less hazardous process be used?
• Engineering: Install guards, ventilation, or automation.
• Administration: Signage, training, or rotation schedules.
• PPE: Implement last-resort personal protective equipment.

Phase IV: Verification & Monitoring

• Assign an owner to every control measure.
• Establish a review date for every "High" or "Critical" risk (Quarterly minimum).
• Audit controls for efficacy during scheduled site inspections.

5. Quality Assurance & Pro-Tips

Best Practices

• The "Control vs. Monitor" Gap: Avoid listing hazards without specific, verifiable control measures. If a control cannot be audited, it is ineffective.
• Living Document: If a hazard register has not been modified in >6 months, it is failing to capture site evolution.

Metric Thresholds

• Residual Risk: Post-control, all risks must be mitigated to "As Low As Reasonably Practicable" (ALARP).
• Closure Rate: 100% of "Critical" risks must have an active, verified control plan within 24 hours of identification.

Common Pitfalls

• Over-reliance on PPE: Treating PPE as a primary control is a frequent audit failure. Focus efforts on Engineering controls.
• Static Registers: Filing a document and forgetting it. The register must be integrated into daily pre-start meetings.

6. Frequently Asked Questions

Q: How often should the entire register be reviewed? A: A formal comprehensive review must occur every 12 months, or immediately following any significant workplace incident or change in process/equipment.

Q: What is the minimum requirement for a "reasonably practicable" control? A: You must balance the likelihood and degree of harm against the cost and availability of the control. In NZ, if the risk of serious injury or death exists, cost is rarely a valid excuse for omitting high-level engineering controls.

Q: Do I need to record minor hazards like "paper cuts"? A: Focus on hazards with the potential for significant harm. Minor risks can be managed via general workplace housekeeping policies rather than detailed registry entries.
