4 Steps to Manage EHS Risk: Identify, Assess, Control and Review

A defined risk control process brings consistency to how risks are identified, prioritized and managed across an organization, helping ensure that controls are selected and maintained in a way that reduces the likelihood of harm.  

The four-step process outlined below draws inspiration from the risk management principles found in international guidance ISO 31000 and the Safe Work Australia Code of PracticeWhile every organization’s approach to this risk control process will vary based on operations, industry requirements and risk profile, this process provides a strong foundation for what a continuous, proactive management cycle should incorporate. 

Breakdown of Risk Management Cycle

Stage 1: Identify Workplace Risks

The risk management cycle begins with identifying the risks that exist in the workplace. This task doesn’t belong to just one person or title; supervisors, safety committees and workers all have a role in recognizing and identifying unsafe working conditions.  

While the specific hazards and risks will vary from organization to organization, common hazards include: 

 

Hazard CategoryExamples of Hazards
General
  • Exit routes clear with locked doors 
  • Broken exit and emergency signs 
  • Busy or unclear aisles and walkways  
  • Inadequate lighting  
  • Dangerous or insufficient material storage 
  • Improper PPE  
Biological
  • Unlabeled waste and refuse stored  
  • Missing, expired or incomplete first aid supplies 
  • Unmaintained eyewash and shower units  
  • Improper labeling of biological materials 
Chemical
  • Inaccessible and outdated Safety Data Sheets  
  • Unlabeled chemical containers  
  • Improper storage of flammable liquids  
  • Improper chemical and respiratory PPE  
Electrical
  • Broken, corroded or unsafe junction boxes, outlets and switch covers  
  • Improper use of extension cords or power strips 
  • Dangerous grounding practices 
  • Unavailable and insufficient lockout tagout procedures for equipment with hazardous energy 
Gravity
  • Missing or broken guardrails  
  • Improper ladder usage 
  • Missing harnesses, lanyards and anchor points  
  • Missing warning signage for restricted access areas near overhead work 
Mechanical
  • Missing machine guarding for moving parts and pinch points 
  • Bypassed interlocks  
  • Missing operating instructions  
  • Missing lockout tagout processes 
  • Unanchored or unsecured equipment where movement could create hazards 

  

Pressure
  • Improper storage of compressed gas cylinders  
  • Damaged hoses, fittings and couplings  
  • Missing eye and face protection where flying particles or pressure release may occur 
  • Missing cave-in protection 
  • Missing safeguards to prevent falls into pits, trenches or excavations

Training Your Workforce to Identify Risks

Besides the controls themselves, one key line of defense a workforce has against workplace risks is the knowledge to identify, mitigate and manage the unsafe work outlined above. If employees don’t know what unsafe work looks like, they won’t be able to act on or report it 

For a holistic identification of potential risks, train your workforce to ask the following questions to examine and assess the workplace: 

  • What elements of the physical, mental or psychosocial work environment could lead to a workplace incident, injury or fatality?  
  • How do the workplace conditions, equipment and tools impact the working environment? Consider the quality, maintenance, noise, pollution, movement, temperature, etc. 
  • What recent workplace changes have impacted how work is carried out or how machines and tools operate? Are new controls or workplace procedures necessary? 
  • How do different workplace procedures, processes, tasks and conditions impact other workplace elements? Will a change in one part of the workplace introduce new risks to another? 
  • How does a combination of hazards increase the level of risk a worker is exposed to? 

How you deliver this training matters almost as much as the content. Use a mix of in-person, online and in-the-flow-of-work refreshers: in-person for job-specific risks, online for standardized baseline training and refreshers delivered while the work is occurring. Don’t wait for a hazard to reveal whether an employee is competent or not; build in hands-on demonstrations or assessments that measure training effectiveness directly. 

Stage 2: Assess Risk Severity

Risk assessments can take different forms, but they all serve the same general purpose: evaluate the likelihood and severity of a risk so the highest-risk situations get addressed first.  

general risk assessment should assess: 

  • Risk severity 
  • Risk likelihood 
  • Existing controls 
  • Urgency of corrective actions 

This feeds directly into the following stage, because the most serious risks demand the strictest and most urgent controls. 

Stage 3: Control Risk

The risk controls themselves are what actually stand between your workforce and a potential injury or fatality. To protect workers effectively, it’s first essential to understand the hierarchy of controls. 

The Hierarchy of Controls (HOC) ranks the most effective ways to control risks, starting with the most effective control and working down to the least effective. This prioritizes eliminating a risk wherever reasonably practicable and minimizing what can’t be eliminated: 

  1. Elimination 
  2. Substitution 
  3. Engineering controls 
  4. Administrative controls 
  5. PPE 

To choose the most effective controls, EHS professionals should rely on guidance from: 

  • Codes of practice 
  • Industry guidance  
  • Manufacturer or equipment information  
  • Past incident investigations 

Importance of Critical Controls

A critical control is one where, if it fails or is absent, there’s little or nothing standing between a hazard and a serious outcome, and where no other control can realistically compensate for that failure. The result of a critical control failure is often a direct or immediate pathway to a fatality or serious injury. 

Any control identified as “critical” should be routinely verified, maintained and kept working. Some industries require organizations to identify and record critical controls for audit purposes, so keeping this information well maintained is crucial for smooth operations.

Stage 4: Review Risk Effectiveness

Never assume a control is working just because it was implemented. As operations, equipment, staffing and conditions change, controls may be weakened. Ongoing control verification is therefore necessary to proactively ensure the effectiveness of controls. Verification can take several forms: 

  • Scheduled inspections or audits 
  • Routine equipment, alarm or procedural tests  
  • Metric analysis 
  • Employee feedback 

The frequency of verification will vary based on severity of the risk and type of control needed. Critical controls, for example, should be reviewed much more frequently than controls for a less severe hazard. 

Control verification can be started by the following questions: 

  • Have all necessary controls been tested and verified to be working properly?  
  • How regularly are controls tested, and is there a documented process for this?  
  • Do all workers understand the necessary controls needed to be in place for any given task? 
  • Do workers recognize when a control is broken or not working correctly?  
  • Do workers have the tools and means to communicate the problem or stop work if necessary? 

When To Use The Risk Management Cycle

The 4-step cycle above should simultaneously be operated on a set schedule as well as triggered by any organizational change that may affect, alter or introduce new risks to a workplace, such as: 

  • Operational, staffing or equipment changes 
  • A serious incident or fatality 
  • Upcoming audits 
  • Introduction of new substance 
  • Reported concerns or complaints 

This turns the risk control process back into stage one, identify, and keeps the cycle moving continuously. 

By following a structured cycle of identification, assessment, control and review, organizations can make better risk-based decisions and direct resources where they will have the greatest impact.
