What is Workplace Safety and Health?
Workplace Safety and Health is about preventing injuries, ill health and incidents at work through practical control measures, effective systems and continuous improvement.
A practical and integrated discipline
WSH involves identifying hazards, assessing risks, implementing suitable controls, monitoring effectiveness and improving systems over time.
People, tasks and systems
Good WSH management considers people, tasks, equipment, work environments, procedures and organisational factors.
Connected with health and human factors
Safety outcomes are influenced by work design, exposure risks, behaviour, supervision and organisational conditions.

Risk Assessment
Risk assessment is the process of identifying hazards, evaluating risks, reviewing existing controls and deciding whether additional controls are needed.
Risk assessment helps organisations prioritise controls before harm occurs and communicate safe ways of working to workers and supervisors.
Common workplace issues
Generic assessments, missing non-routine tasks, controls not linked to actual work, weak implementation and limited review after changes.
What to consider
Task steps, hazards, exposure, likelihood, severity, existing controls, hierarchy of controls, residual risk and responsible persons.
Review approaches
Task-based assessment, workplace-level assessment, job observation, consultation with workers and review of incidents or near misses.
Improvement focus
Assessments should be reviewed when work changes, incidents occur, controls fail, new hazards arise or periodic review is due.
When to seek support
Seek professional support when risks are complex, controls are inconsistent, incidents recur, or an independent review is required.
IEH perspective
IEH supports practical, proportionate and risk-based review of workplace safety and health arrangements.
Incident Prevention
Incident prevention focuses on proactive identification of unsafe conditions, near misses, system weaknesses and behavioural factors before serious harm occurs.
Preventing recurrence requires learning from weak signals, not only reacting after injuries or major events.
Common workplace issues
Under-reporting, blame-focused investigations, repeated corrective actions, weak root cause analysis and poor closure of actions.
What to consider
Near-miss reporting, unsafe condition reporting, supervision, work pressure, communication, equipment condition and procedural clarity.
Review approaches
Incident trend review, learning reviews, corrective action tracking, worker engagement and verification that controls remain effective.
Improvement focus

Frequently asked questions
Short answers to common questions on workplace safety and health.
What is Workplace Safety and Health?
Workplace Safety and Health is the practice of preventing work-related injuries, ill health and incidents through hazard identification, risk assessment, control measures, monitoring and continuous improvement.
Why is risk assessment important?
Risk assessment helps organisations identify what can cause harm, evaluate the level of risk, select suitable controls and communicate safe work requirements before incidents occur.
When should a company review its risk assessments?
Risk assessments should be reviewed when work processes change, new equipment or substances are introduced, incidents or near misses occur, controls are found to be ineffective, or periodic review is due.
What is the difference between hazard and risk?
A hazard is something with the potential to cause harm. Risk considers the likelihood and severity of harm arising from exposure to that hazard.
What should be included in a workplace inspection?
A workplace inspection may include housekeeping, access and egress, equipment condition, storage, signage, emergency arrangements, hazardous substances, work activities and verification of controls.
How can incidents be prevented?
Incidents can be prevented through effective risk assessment, control implementation, near-miss reporting, worker engagement, supervision, incident learning, corrective action tracking and regular review of workplace conditions.
Why do human factors matter in safety?
Human factors matter because people work within systems. Workload, fatigue, communication, supervision, equipment design, procedures and organisational conditions can all influence safety performance.
What is safety culture?
Safety culture refers to the shared values, behaviours, leadership actions and everyday practices that influence how safety is understood, prioritised and managed in an organisation.
When should professional WSH support be sought?
Professional support may be useful when risks are complex, incidents recur, controls are uncertain, procedures need review, emergency arrangements require improvement or an independent assessment is needed.
How does WSH relate to occupational hygiene and ergonomics?
WSH overlaps with occupational hygiene and ergonomics because workplace safety and health risks include physical, chemical, biological, ergonomic, human factors and organisational aspects of work.
Need help strengthening workplace safety and health practices?
IEH supports organisations with WSH reviews, risk assessment review, workplace inspections, emergency planning, contractor safety review, human factors review, incident prevention support and customised training.
