Hazard identification and risk assessment are fundamental parts of an effective workplace safety program. The goal is straightforward: identify conditions or practices that could cause harm, evaluate how serious those risks may be, and correct them before they contribute to an injury, illness, equipment loss, or compliance problem.
Some workplace hazards are obvious, such as an unguarded machine, exposed electrical wiring, or a blocked exit. Others are easier to overlook, including repetitive-motion risks, chemical exposure, changing work conditions, inconsistent procedures, or a written safety program that no longer matches what employees actually do.
A strong hazard assessment process helps employers move from reacting to incidents to identifying and controlling risk before something goes wrong. It can also help uncover issues that may surface during an OSHA inspection.
Hazard Identification and Risk Assessment at a Glance
A practical risk assessment process generally follows five steps. Employers may document these steps using a risk assessment tool, checklist, or risk assessment template appropriate for their workplace.
What Is Hazard Identification and Risk Assessment?
Hazard identification is the process of finding workplace conditions, equipment, substances, behaviors, or processes that have the potential to cause injury or illness.
Risk assessment goes one step further by considering how likely it is that the hazard could cause harm and how severe the consequences could be.
The terms are related, but they do not mean exactly the same thing.
Hazard: Something with the potential to cause harm.
Risk: The likelihood and potential severity of harm resulting from that hazard.
For example, a forklift operating near pedestrians is a hazard. The level of risk changes depending on factors such as traffic volume, visibility, employee exposure, speed, training, and whether pedestrians and equipment are physically separated.
Examples of Workplace Hazards and Controls
| Hazard | Potential Harm | Risk Factors | Possible Controls |
|---|---|---|---|
| Unguarded machinery | Crushing, cutting, amputation | Frequent employee access to moving parts | Machine guarding and restricted access |
| Wet walking surface | Slip or fall | High foot traffic or recurring leaks | Repair source, improve drainage, housekeeping |
| Chemical vapor or dust | Respiratory or other health effects | Concentration, ventilation, duration of exposure | Substitution, ventilation, work practices, PPE |
| Forklift traffic | Struck-by or crushing injury | Pedestrian interaction, blind corners, speed | Traffic separation, procedures, visibility, training |
Six Types of Workplace Hazards to Look For
Effective workplace hazard identification requires looking beyond the most obvious physical dangers. Hazards may fall into several broad categories.
Safety Hazards
Falls, machinery, electrical hazards, moving vehicles, poor housekeeping, blocked exits, and unsafe equipment.
Chemical Hazards
Hazardous liquids, gases, vapors, fumes, dusts, cleaning chemicals, and other substances employees may encounter.
Biological Hazards
Bloodborne pathogens, bacteria, viruses, mold, bodily fluids, insects, animals, and other biological exposures.
Ergonomic Hazards
Repetitive motion, heavy lifting, awkward posture, workstation design, forceful exertion, and prolonged static positions.
Physical Hazards
Noise, heat, cold, vibration, radiation, pressure, and other environmental conditions that can affect employees.
Human & Organizational Hazards
Fatigue, communication failures, inadequate procedures, production pressure, inconsistent training, and unsafe work practices.
How to Perform a Workplace Hazard Identification and Risk Assessment
A workplace assessment is most useful when it follows a consistent process instead of relying on a quick visual walkthrough. The following steps can help create a more complete picture of workplace risk.
1. Review Existing Safety Information
Begin with information the organization already has. Past incidents, near misses, employee reports, and previous inspection findings can reveal hazards that may not be obvious during a single walkthrough.
Review information such as:
- Injury and illness records
- Near-miss reports
- Employee safety concerns
- Safety Data Sheets (SDS)
- Equipment manuals
- Previous inspection or audit findings
- Existing written safety programs
- Training records
- Maintenance records
2. Inspect the Workplace
Walk through work areas and observe both conditions and employee practices. Avoid limiting the inspection to obvious housekeeping problems.
Look at:
- Machinery and equipment
- Electrical systems
- Walking and working surfaces
- Forklift and vehicle traffic
- Personal protective equipment
- Chemical storage, labeling, and Hazard Communication
- Emergency exits and emergency equipment
- Fall hazards
- Machine guarding
- Housekeeping
- Employee work practices
It is also important to evaluate non-routine activities such as maintenance, equipment setup, cleaning, shutdowns, repairs, and unusual production tasks.
3. Talk to Employees
Employees performing the work often have information that cannot be discovered from written procedures alone. They may know which equipment regularly malfunctions, which tasks are difficult to perform safely, or where procedures do not reflect actual working conditions.
Ask employees questions such as:
- What part of your job concerns you most?
- What task is most difficult to perform safely?
- Have you experienced any recent near misses?
- Are there procedures that do not match how the work is actually performed?
- Are there hazards that employees have simply become accustomed to?
4. Evaluate Likelihood and Severity With a Risk Assessment Matrix
Once hazards have been identified, assess how likely each hazard is to cause harm and how serious the potential consequences may be. This step helps employers compare hazards and determine which corrective actions deserve the highest priority.
A risk assessment matrix is one common risk assessment tool for organizing this information. It compares likelihood and severity to produce a relative risk level. Organizations may also use another documented method as part of their overall risk assessment process.
| Likelihood | Minor | Moderate | Serious | Catastrophic |
|---|---|---|---|---|
| Unlikely | Low | Low | Medium | High |
| Possible | Low | Medium | High | High |
| Likely | Medium | High | High | Critical |
| Frequent | High | High | Critical | Critical |
5. Prioritize Corrective Actions
Hazards should not simply be added to a list and forgotten. An effective risk management process assigns responsibility, establishes corrective actions, and prioritizes issues according to their potential consequences and employee exposure.
Conditions presenting an immediate or serious danger should receive urgent attention. Lower-risk issues should still be tracked through completion rather than remaining indefinitely unresolved.
6. Use the Hierarchy of Controls
When deciding how to address a hazard, consider controls in order of effectiveness. Whenever feasible, correcting the source of the hazard is generally more reliable than depending entirely on employee behavior or personal protective equipment.
7. Document Corrective Actions and Reassess
Risk assessment is not a one-time exercise. Conditions change as businesses add employees, introduce new equipment, modify processes, use new chemicals, or change job responsibilities.
Some workplaces also use a dynamic risk assessment when conditions can change quickly. Rather than relying only on a previously completed assessment, employees or supervisors reassess hazards as conditions, tasks, equipment, or the work environment change. This can be particularly useful for non-routine or rapidly changing work, but it should complement rather than replace appropriate documented safety procedures.
Review hazard assessments when:
- New equipment or machinery is introduced
- New chemicals or materials are used
- Work processes change
- Employees begin new or non-routine tasks
- An incident or near miss occurs
- Employees identify new safety concerns
- Inspection findings reveal deficiencies
- Applicable safety requirements change

SEE WHAT OSHA WOULD FLAGCommon Workplace Hazards That Get Missed
Many serious hazards are not hidden because they are impossible to see. They are missed because employees become accustomed to them, because conditions gradually change, or because written procedures are not compared against actual operations.
Commonly overlooked issues may include:
- Temporary electrical cords or makeshift electrical setups
- Blocked exits, extinguishers, electrical panels, or emergency equipment
- Forklift and pedestrian interaction
- Damaged or missing machine guards
- Improper chemical labeling or storage
- Noise exposure
- Heat exposure and heat illness prevention
- Ergonomic risks and repetitive-motion tasks
- Poor housekeeping
- Unsafe ladder use
- Outdated safety procedures
- Training records that do not reflect actual employee duties
- Written safety policies that do not match actual workplace practices
Why Workplace Hazards Get Missed
Familiarity and Normalization
Employees who work around the same condition every day may gradually stop recognizing it as unusual. A damaged guard, recurring spill, blocked pathway, or unsafe shortcut can become normalized if it remains uncorrected for long enough.
Inadequate or Inconsistent Training
Employees need to understand the hazards associated with their actual job duties. Generic training may not prepare workers to identify risks created by specialized equipment, changing processes, or location-specific conditions.
Production Pressure
When speed consistently takes priority over safe work practices, employees may bypass procedures, ignore developing hazards, or avoid reporting problems that could slow production.
Communication Barriers
Safety instructions must be understandable to the employees expected to follow them. Language, literacy, unclear procedures, inconsistent terminology, and poor communication between departments can all create safety gaps.
Overconfidence
Experience can improve hazard recognition, but it can also create overconfidence. Statements such as "we've always done it this way" or "nothing has happened yet" do not demonstrate that a condition is safe.
Weak Reporting Culture
Employees are less likely to report hazards when they believe management will ignore the concern, blame the employee, or view reporting as an inconvenience. A strong safety program creates clear ways to report hazards and demonstrates that legitimate concerns will be addressed.
Workplace Hazard Identification Checklist
Before considering a workplace hazard assessment complete, review the following questions.
- Have previous incidents and near misses been reviewed?
- Have employees been asked about hazards they encounter?
- Have both routine and non-routine tasks been evaluated?
- Are chemical hazards and SDS requirements addressed?
- Have machinery, electrical, vehicle, and fall hazards been evaluated?
- Is required PPE appropriate for the hazards present?
- Are emergency exits and emergency equipment accessible?
- Do written procedures match actual workplace practices?
- Have identified hazards been prioritized by risk?
- Has responsibility for corrective action been assigned?
- Is there a process for verifying corrective actions are completed?
- Is there a defined process for reassessing the workplace when conditions change?
Use Hazard Identification as Part of a Larger Safety Program
Hazard identification works best when it is connected to the rest of the organization's safety and compliance process. Inspection findings should influence employee training, written procedures, documentation, equipment controls, and future assessments.
For example, a walkthrough may identify a hazard that is physically corrected immediately but also reveal that the organization's written procedure is outdated or that affected employees have not received appropriate safety training.
This is why effective workplace safety requires more than simply spotting hazards — employers also need a process for documenting findings, correcting deficiencies, communicating changes, training employees, and confirming that controls remain effective.
