Risk Control Measures – Complete Guide for Workplace Safety
Introduction
Identifying a workplace hazard is only the first step in safety management.
The more important question is:
What are we going to do to control the risk?
Every workplace contains hazards. These may include chemicals, electricity, fire, manual handling, material movement, working at height, machinery, slips and trips, vehicle movement, noise, dust, and many other conditions.
A hazard may exist without causing an incident, but when people are exposed to that hazard, it can create risk.
Effective safety management therefore requires suitable risk control measures to reduce the possibility and/or severity of harm.
Risk control measures are the actions, systems, equipment, procedures, and practices used to eliminate hazards or reduce risks to an acceptable level.
For example, if workers handle chemical containers, simply telling them to "be careful" is not enough. The workplace may need suitable storage, chemical compatibility controls, SDS availability, handling procedures, spill kits, emergency arrangements, training, and appropriate PPE.
This article explains risk control measures in detail, including their relationship with HIRA, the Hierarchy of Controls, practical warehouse examples, control selection, implementation, monitoring, common mistakes, and continual improvement.
What are Risk Control Measures?
Risk control measures are actions implemented to prevent an identified hazard from causing harm or to reduce the likelihood or severity of its consequences.
Simple Definition
Risk control measures are preventive and protective actions used to eliminate hazards or reduce workplace risks.
Examples include:
- Eliminating a hazardous activity.
- Replacing a hazardous substance.
- Installing machine guards.
- Providing ventilation.
- Establishing SOPs.
- Conducting employee training.
- Providing PPE.
- Performing regular inspections.
- Implementing LOTO.
- Installing fire protection systems.
- Establishing emergency procedures.
Why are Risk Control Measures Important?
A risk assessment without effective controls has limited value.
For example:
Hazard: Chemical leakage
Risk: Chemical exposure and environmental contamination
If the HIRA simply records the hazard and risk but does not identify suitable controls, the organization has not adequately addressed the problem.
Effective controls help to:
- Prevent accidents.
- Reduce injuries.
- Reduce chemical exposure.
- Prevent equipment damage.
- Reduce fire risk.
- Protect employees and visitors.
- Improve emergency preparedness.
- Support legal and organizational requirements.
- Improve workplace safety culture.
Hazard, Risk and Control – Understanding the Difference
These three terms are closely related but should not be confused.
Hazard
A hazard is something that has the potential to cause harm.
Example: Chemical stored in a container.
Risk
Risk considers the possibility of harm and the potential consequence.
Example: Worker may be exposed to the chemical if the container leaks.
Control Measure
A control is the measure used to prevent or reduce that risk.
Example:
- Suitable storage.
- Container inspection.
- Chemical compatibility.
- SDS availability.
- Spill response procedure.
- PPE.
A simple way to remember this is:
Hazard → Exposure → Risk → Control
Relationship Between HIRA and Risk Control Measures
HIRA stands for Hazard Identification and Risk Assessment.
A typical HIRA process involves:
- Identify the activity.
- Identify the hazard.
- Identify possible consequences.
- Assess the risk.
- Identify existing controls.
- Determine additional controls.
- Assign responsibility.
- Implement actions.
- Verify effectiveness.
- Review and improve.
Risk control measures are therefore an important part of the HIRA process.
Hierarchy of Controls and Risk Control Measures
Risk controls should be selected using a systematic approach.
The commonly used Hierarchy of Controls consists of:
- Elimination
- Substitution
- Engineering Controls
- Administrative Controls
- PPE
The principle is to consider stronger controls before depending mainly on procedures and PPE.
1. Elimination
Elimination means removing the hazard completely.
This is generally the strongest control because the hazard itself is no longer present.
Examples
- Remove an unnecessary hazardous chemical.
- Eliminate an unnecessary work-at-height activity.
- Remove unnecessary manual lifting.
- Eliminate an unnecessary ignition source.
- Remove an unsafe process step.
Workplace Example
If employees need to climb onto pallets to inspect stored material, the process may be redesigned so inspection can be performed from ground level.
The climbing hazard is eliminated.
2. Substitution
Substitution means replacing a hazardous material, process, or equipment with a less hazardous alternative.
Examples
- Replace a hazardous chemical with a less hazardous alternative.
- Replace a high-noise process with a lower-noise option.
- Use safer equipment.
- Use smaller or easier-to-handle packages where technically suitable.
Substitution should always be evaluated carefully because the replacement may introduce a different hazard.
3. Engineering Controls
Engineering controls physically isolate workers from hazards or reduce the hazard through design.
Examples include:
- Machine guards.
- Barriers.
- Interlocks.
- Ventilation.
- Enclosures.
- Guardrails.
- Automatic shutdown systems.
- Emergency stops.
- Secondary containment.
- Mechanical lifting equipment.
Engineering controls are often valuable because they can reduce dependence on individual worker behavior.
4. Administrative Controls
Administrative controls change how work is performed.
Examples include:
- SOPs.
- Work instructions.
- Training.
- Toolbox talks.
- Job rotation.
- Safety signs.
- Permit-to-work systems.
- Inspection schedules.
- Emergency procedures.
- Restricted access.
- Safe operating procedures.
Administrative controls are important but often depend on employees consistently following the established system.
5. Personal Protective Equipment
PPE provides protection to the individual worker from remaining hazards.
Examples include:
- Safety helmet.
- Safety shoes.
- Safety goggles.
- Face shield.
- Gloves.
- Chemical-resistant clothing.
- Hearing protection.
- Respiratory protection.
- Fall protection equipment.
PPE should be selected based on the hazard assessment and the specific task.
It should not automatically be treated as the only control.
Types of Risk Control Measures
Risk control measures can also be grouped according to their practical purpose.
Preventive Controls
These controls are intended to prevent an incident from occurring.
Examples:
- Training.
- Machine guards.
- Inspection.
- Maintenance.
- Safe storage.
- LOTO.
- Chemical compatibility.
Protective Controls
These reduce the consequences if an incident occurs.
Examples:
- Fire extinguishers.
- Emergency showers.
- Eye wash facilities.
- Spill kits.
- Safety barriers.
- PPE.
- Emergency response systems.
Detective Controls
These help identify unsafe conditions or failures.
Examples:
- Workplace inspections.
- Fire alarm systems.
- Gas detection.
- Temperature monitoring.
- Electrical inspections.
- Near-miss reporting.
A strong safety system may use all three types.

The strongest approach is to reduce interaction between pedestrians and moving vehicles through physical separation wherever practical.
Risk Control Measures for Working at Height
Controls should prioritize fall prevention.
Possible Controls
- Eliminate work at height.
- Use suitable platforms.
- Install guardrails.
- Provide safe access.
- Inspect access equipment.
- Establish work-at-height procedures.
- Train workers.
- Use fall-protection systems where required.
PPE such as harnesses may be necessary, but should not automatically replace stronger fall-prevention measures.
Risk Control Measures for Emergency Situations
Emergency controls may include:
- Emergency exits.
- Fire alarms.
- Emergency lighting.
- Fire extinguishers.
- Fire hydrant systems where applicable.
- First aid facilities.
- Emergency contact information.
- Spill kits.
- Safety shower/eye wash where required.
- Assembly point.
- Emergency response team.
- Mock drills.
Emergency controls should be regularly inspected and tested according to applicable requirements and workplace procedures.
Risk Control Measures Should be Specific
A common problem in HIRA is writing controls that are too general.
Weak Control
"Training provided."
Better Control
"Employees handling chemicals are trained on chemical hazards, SDS requirements, PPE, spill response, and emergency actions."
Another example:
Weak
"PPE provided."
Better
"Suitable hand, eye, and foot protection is provided based on the chemical hazard assessment and applicable SDS requirements."
Specific controls are easier to implement and verify.
Existing Controls vs Additional Controls
HIRA should distinguish between:
Existing Controls
Measures already implemented.
For example:
- PPE available.
- SDS displayed.
- Fire extinguisher installed.
- Spill kit available.
Additional Controls
Actions required to further reduce the risk.
For example:
- Improve chemical segregation.
- Add additional signage.
- Conduct refresher training.
- Improve inspection frequency.
- Install additional physical protection.
This distinction makes the risk assessment more meaningful.
Risk Control Action Plan
When an additional control is required, define:
- What action is required?
- Who is responsible?
- Target date.
- Current status.
- Evidence of completion.
- Effectiveness verification.
Example
Hazard: Damaged chemical container
Risk: Chemical leakage/exposure
Action: Introduce monthly container-condition inspection.
Responsible: Warehouse In-charge
Status: Implemented
Evidence: Inspection checklist
Effectiveness: No uncontrolled damaged containers observed during subsequent inspections.
Control Measures Must Be Monitored
Implementing a control is not the end of the process.
The organization should ask:
Is the control actually working?
For example:
Control
Chemical spill kit provided.
Verification
- Is the spill kit accessible?
- Is it complete?
- Are employees aware of its location?
- Are materials within expiry/useful condition where applicable?
- Has the team been trained?
Similarly:
Control
Fire extinguisher installed.
Verification
- Is it accessible?
- Is inspection current?
- Is the seal/intact condition satisfactory?
- Is signage visible?
- Are employees trained?
Effectiveness of Risk Controls
A control should be considered effective only when there is reasonable evidence that it is functioning as intended.
Evidence may include:
- Inspection records.
- Training records.
- Maintenance records.
- Drill reports.
- Observation records.
- Near-miss trends.
- Incident trends.
- Audit findings.
- Photographs.
- Corrective action records.
Risk Control Measures and Continual Improvement
Workplace risks change over time.
Therefore, risk controls should be reviewed when:
- New equipment is introduced.
- New chemicals are purchased.
- Warehouse layout changes.
- Processes change.
- An incident occurs.
- A near miss occurs.
- New legal requirements apply.
- Audit findings identify weaknesses.
- Workers report a safety concern.
Continual improvement means asking:
Can this control be made stronger, more reliable, or more practical?
Common Mistakes in Risk Control
1. Providing PPE and Closing the Risk
PPE may be necessary, but it does not automatically mean the risk is adequately controlled.
2. Writing Very General Controls
"Training provided" or "PPE provided" may not explain how the hazard is actually controlled.
3. No Responsible Person
An action without ownership may remain incomplete.
4. No Verification
A control may be recorded as completed without checking whether it works.
5. Ignoring Worker Feedback
Workers often identify practical problems that may not be visible during a document review.
6. Not Updating HIRA
When processes change, old controls may no longer be adequate.
7. Focusing Only on Accidents
Near misses and unsafe conditions can provide valuable opportunities for improving controls before an accident occurs.
Personal Experience (Original Practical Learning)
From my experience in warehouse and industrial safety, I have learned that a risk control measure becomes meaningful only when it is practical, implemented, and regularly checked. During workplace inspections, a control may look perfect on paper, but actual conditions can be different. For example, PPE may be available but not used correctly, a spill kit may be installed but incomplete, or an emergency exit may exist but become blocked by material. This is why I believe risk control should not stop at writing the control in HIRA. The control should be implemented, monitored, verified, and improved whenever necessary.
Key Learning
- A control written in HIRA is not automatically an implemented control.
- Responsibility should be clearly assigned.
- Controls should be practical for workers.
- Inspection should verify actual implementation.
- Near misses can identify weak controls.
- Stronger controls should be considered whenever practical.
Risk Control Measures and ISO 45001
Risk control measures support the occupational health and safety management system by helping organizations manage identified hazards and risks.
They may be connected with:
- Hazard identification.
- Risk assessment.
- Operational planning.
- Competence.
- Awareness.
- Communication.
- Emergency preparedness.
- Incident investigation.
- Corrective action.
- Continual improvement.
The exact controls required depend on the organization's activities, hazards, risk assessment, applicable legal requirements, and operational conditions.
Practical Risk Control Review Questions
During a workplace inspection or HIRA review, ask:
Hazard
What hazard exists?
Exposure
Who can be exposed?
Consequence
What could happen?
Existing Control
What controls are already available?
Hierarchy
Can the hazard be eliminated or reduced at source?
Additional Control
What further action is required?
Responsibility
Who will implement it?
Verification
How will we confirm completion?
Effectiveness
Did the control actually reduce the risk?
Review
When should the control be reviewed again?

Frequently Asked Questions (FAQ)
Q1. What are risk control measures?
Risk control measures are actions used to eliminate hazards or reduce workplace risks and their potential consequences.
Q2. What is the difference between risk assessment and risk control?
Risk assessment evaluates the risk associated with a hazard. Risk control involves selecting and implementing measures to reduce that risk.
Q3. Is PPE a risk control measure?
Yes. PPE is an important risk control, particularly for residual risk, but it should not automatically be the only control.
Q4. What is the best risk control?
Elimination is generally the strongest control because it removes the hazard. However, the appropriate control depends on the specific workplace hazard and feasibility.
Q5. Why should engineering controls be considered?
Engineering controls can physically isolate workers from hazards and can reduce dependence on individual behavior.
Q6. Can one hazard require multiple controls?
Yes. Many workplace hazards require several layers of control.
Q7. Should risk controls be reviewed?
Yes. Controls should be reviewed when conditions change and when incidents, near misses, inspections, audits, or other information indicate that improvement is required.
Q8. Who should implement risk controls?
Responsibility should be assigned to an appropriate person based on competence, authority, and the nature of the action.
Q9. How do we know whether a control is effective?
Effectiveness can be evaluated through inspections, observations, records, incident/near-miss information, audits, testing, and other appropriate evidence.
Q10. Are risk control measures important for HIRA?
Yes. Risk control measures are a fundamental part of converting HIRA findings into practical risk-reduction actions.
Conclusion
Risk assessment is not complete simply because hazards have been identified and a risk score has been calculated.
The real objective of safety management is to control the risk effectively.
A strong risk control process should follow a systematic approach:
Identify Hazard → Assess Risk → Select Controls → Implement → Monitor → Verify → Improve
Whenever possible, organizations should prioritize stronger controls through the Hierarchy of Controls:
Elimination → Substitution → Engineering Controls → Administrative Controls → PPE
For warehouse and industrial environments, effective risk controls can help manage:
- Chemical hazards.
- Fire hazards.
- Electrical hazards.
- Manual handling.
- Material storage.
- Vehicle movement.
- Slips and trips.
- Working at height.
- Emergency situations.
The most important lesson is:
A risk control measure is effective only when it is properly selected, implemented, understood, maintained, and verified in the actual workplace.
Safety is not only about having controls on paper.
Good safety management means making sure the controls work in real life.
