NEBOSH IG1 – Element 4: Health and Safety Monitoring and Measuring
Introduction
Monitoring and measuring health and safety performance is a critical part of any management system. Element 4 of NEBOSH IG1 focuses on the techniques and methods organizations use to assess their health and safety performance, identify areas for improvement, and ensure compliance with legal and organizational standards.
Effective monitoring ensures that policies and procedures are working, hazards are controlled, and risks are minimized. Measuring performance helps in decision-making, continual improvement, and demonstrating due diligence to regulators and stakeholders.
This element covers:
-
Active and reactive monitoring
-
Health and safety audits
-
Investigations, inspections, and sampling
-
Recording and reporting data
-
Reviewing health and safety performance

4.1 Active and Reactive Monitoring
Monitoring can be classified into active (proactive) and reactive methods. Both are essential for a comprehensive understanding of health and safety performance.
4.1.1 Active Monitoring
Active monitoring aims to prevent accidents and incidents before they occur. It involves assessing the effectiveness of control measures and compliance with procedures.
Methods include:
-
Workplace inspections: Routine checks of equipment, machinery, and work practices.
-
Safety tours: Management-led walkthroughs to identify hazards and engage employees.
-
Health surveillance: Monitoring workers’ health to detect early signs of occupational illness.
-
Observation: Watching work processes to ensure safe practices are followed.
-
Audits of procedures: Checking compliance with safety systems and policies.
Example:
A chemical plant regularly monitors workers’ exposure to solvents using air sampling and health checks to prevent long-term illnesses.
4.1.2 Reactive Monitoring
Reactive monitoring focuses on investigating incidents after they occur to prevent recurrence.
Methods include:
-
Accident and near-miss reporting: Detailed recording of injuries, property damage, or unsafe acts.
-
Incident investigations: Analysis of root causes and underlying factors.
-
Sick leave and absenteeism analysis: Identifying trends related to occupational illness.
-
Trends in insurance claims: Monitoring patterns of claims to detect problem areas.
Example:
If a worker slips on a wet floor, reactive monitoring identifies the immediate cause (wet floor), underlying cause (poor housekeeping), and root cause (lack of cleaning schedule enforcement).
4.1.3 Benefits of Active and Reactive Monitoring
-
Early detection of hazards.
-
Prevention of accidents and illnesses.
-
Improvement of safety procedures.
-
Evidence of legal compliance.
-
Supports continuous improvement.
4.2 Health and Safety Audits
A health and safety audit is a systematic review of an organization’s health and safety management system. It evaluates compliance, identifies gaps, and suggests improvements.
4.2.1 Purpose of Audits
-
Ensure compliance with law, standards, and internal policies.
-
Identify weaknesses and strengths in the system.
-
Provide evidence of due diligence in case of legal scrutiny.
-
Improve performance and reduce incidents.
4.2.2 Types of Audits
-
Internal audits: Conducted by trained employees or safety officers.
-
External audits: Performed by independent bodies or certification organizations (e.g., ISO 45001 audits).
Example:
A manufacturing company may conduct quarterly internal audits to check machine guarding, training records, and PPE compliance, and annually use an external auditor for ISO 45001 certification.
4.2.3 Audit Process
-
Planning: Define scope, objectives, and criteria.
-
Data collection: Review documents, observe processes, interview staff.
-
Analysis: Compare findings with standards and policies.
-
Reporting: Document strengths, weaknesses, and recommendations.
-
Follow-up: Ensure corrective actions are implemented.
Benefits:
-
Improved legal compliance.
-
Identification of training needs.
-
Strengthened safety culture.
4.3 Investigations, Inspections, and Sampling
4.3.1 Investigations
Investigations identify causes of accidents, near misses, and occupational illnesses. They help organizations prevent recurrence and improve systems.
Steps include:
-
Secure and examine the scene.
-
Collect evidence (photographs, statements, equipment checks).
-
Determine immediate, underlying, and root causes.
-
Recommend corrective and preventive actions.
-
Record findings and communicate lessons learned.
Example:
A chemical spill is investigated, revealing poor labeling and insufficient training, prompting a new chemical handling program.
4.3.2 Inspections
Inspections are planned checks to identify hazards and ensure compliance with safety standards.
Types of inspections:
-
Routine inspections: Daily or weekly checks of workplaces and equipment.
-
Formal inspections: Scheduled, documented inspections covering all areas.
-
Special inspections: Conducted after incidents, changes in process, or new legislation.
Example:
A construction site inspection may check scaffolding stability, PPE usage, and storage of hazardous materials.
4.3.3 Sampling
Sampling involves measuring exposure levels to hazards such as chemicals, dust, noise, or vibration.
Purpose:
-
Assess risk and compliance with legal exposure limits.
-
Identify need for control measures.
-
Monitor effectiveness of existing controls.
Example:
Regular air sampling in a painting facility ensures solvent vapors are within safe limits, protecting workers’ health.
4.4 Recording and Reporting Data
Accurate recording and reporting are vital for tracking performance and demonstrating compliance.
4.4.1 Recording
-
Maintain logs of incidents, near misses, inspections, and audits.
-
Keep training records, PPE issuance, and health surveillance data.
-
Document risk assessments, emergency drills, and corrective actions.
Benefits:
-
Provides evidence for regulators and auditors.
-
Supports analysis of trends.
-
Facilitates lessons learned.
4.4.2 Reporting
-
Internal reporting: To management for action and review.
-
External reporting: To regulators, insurers, or stakeholders as required by law.
-
Formats may include incident reports, audit reports, KPI dashboards.
Example:
A workplace may submit quarterly accident statistics to the safety committee and annual reports to the regulatory authority.
4.4.3 Benefits of Effective Recording and Reporting
-
Informs decision-making.
-
Enables trend analysis.
-
Demonstrates compliance.
-
Supports continuous improvement.
-
Enhances accountability.
4.5 Reviewing Health and Safety Performance
Reviewing performance ensures the HSMS remains effective and relevant.
4.5.1 Management Review
-
Conducted by senior management to evaluate overall system effectiveness.
-
Considers audit results, incident trends, compliance, and risk assessments.
-
Identifies areas for improvement and sets new objectives.
Example:
Annual review of a factory’s HSMS might reveal improvements in noise control, updated training needs, or introduction of new PPE.
4.5.2 Performance Indicators
-
Leading indicators (proactive): Training completion, inspection frequency, risk assessment updates.
-
Lagging indicators (reactive): Accident rates, lost time injuries, near misses.
Example:
A leading indicator is the number of fire drills conducted; a lagging indicator is the number of slips, trips, and falls.
4.5.3 Continuous Improvement
-
Lessons from monitoring, audits, and reviews feed back into planning.
-
Policies, procedures, and training are updated accordingly.
-
Encourages a cycle of Plan-Do-Check-Act.
