Hazard Identification: what is it?
Identifying hazards is the first step in making products and processes safer. Therefore, all managements system standards connected with safety in any way contain requirements for hazard and risk identification.
Whether food safety or occupational health and safety, hazards can be multifaceted and ever evolving. It makes the process of identifying them challenging. Hazard recognition will help any organization manage more effectively and it is the cornerstone of proactive safety processes and culture. Adopting it makes assessment and control of hazards integral to the organization’s daily operations. It sets the stage for a structured approach and promotes the collective responsibility to engage in critical safety practices.
What is a hazard?
A hazard is a source with a potential to cause harm or adverse health effects on a person(s). It does not necessarily lead to harm but has the capacity to do so.
Identifying hazards in the workplace is essential, as they can range from the tangible like unguarded machinery, to the intangible such as stress or high workloads. Hazards can be as obvious as a spill on the floor or as subtle as long-term exposure to low levels of toxic chemicals.
Food safety hazards refer to biological, chemical or physical contamination occurring along the supply chain from raw material production, procurement and handling to manufacturing, distribution and consumption. The risk of harm is to the end user rather than personnel at the food manufacturer.
What is hazard identification: a definition
Hazard identification encapsulates the complex process of recognizing, documenting and understanding the various potential sources of harm. The systematic approach involves a deep understanding of the work environment and interactions between workers, machinery, tools and processes, for example.
A thorough hazard identification process is key for an organization to effectively manage its safety risks.
Types of hazards
Occupational health and safety hazards are categorized to help identify, assess and manage risks effectively. Understanding the different types is crucial to implement appropriate safety measures. For example:
Physical Hazards
Physical hazards are environmental factors that can cause harm without necessarily touching the body. They include extreme temperatures, noise exposure, radiation from various sources and poor lighting.
Chemical Hazards
Chemical hazards occur when a worker is exposed to any chemical preparation in the workplace in any form (solid, liquid or gas). Some are safer than others, but for some chemicals even minimal exposure can be dangerous.
Biological Hazards
Biological hazards include exposure to harm or disease associated with working with animals, people or infectious materials. Workplaces like hospitals, laboratories and outdoor work can expose workers to blood or other bodily fluids, bacteria and viruses, insect bites or pollen.
Ergonomic Hazards
Ergonomic hazards relate to the physical aspects of work. They occur when the type of work, body positions and working conditions put strain on the body. Improper desk setup, poor posture and repetitive movements can lead to carpal tunnel syndrome or chronic back pain.
Safety Hazards
Safety hazards are the most common and are present in most workplaces. They include unsafe conditions that can cause injury, illness or death.
Psychological Hazards
Psychological hazards are increasingly impacting workers' mental health and well-being. These can include workplace bullying, violence and workload demands.
How to identify and recognize hazards?
The process of hazard identification and risk assessment is a proactive, continuous effort to ensure safety. It involves a combination of regular inspections, employee engagement, incident investigation, job analysis and risk assessment.

But how can hazards be identified in practice? Implementing these steps creates a safer work environment and protects valuable assets, i.e. employees and end consumers.
Inspection
This cornerstone in hazard recognition involves a thorough examination of the workplace, including equipment, machinery, work areas and practices.
Incident Investigation
When incidents occur, an investigation provides critical insights into the hazards present. This involves looking at what happened and why it happened. Was there a failure in processes, equipment or communication? Understanding the root cause is key to preventing the hazard(s) in the future.
Employee Feedback
Employees are often the first to notice changes in the workplace signaling a potential hazard. They have firsthand experience with the tools, materials and conditions in the environment. Encouraging a culture where employees feel comfortable reporting potential hazards without fear of reprisal is essential.
Job Analysis
Each job has its own potential hazards, which can be identified through a detailed analysis, involving a break-down of each task into its component steps and considering the associated hazards.
Risk Assessment
This is the process of evaluating potential risks that may be associated with identified hazards. It involves determining the likelihood of the hazard leading to an adverse event and the severity of the outcome.
Continuous Improvement
Hazard identification is an ongoing process. As work environments and processes evolve, so do the potential hazards. Continuous improvement involves regularly reviewing and updating hazard identification processes to ensure they remain effective and relevant.
Examples of hazard identification
There are many forms of hazard. Understanding how to identify hazards is a crucial step in effective risk assessment and control. For example:
- A Wet Floor: When a floor is wet from a spill, cleaning or a leak, it becomes a slip hazard. If a live electrical cable comes into contact, there is the potential for electrocution or a fire. The immediate action is to mark the area with signage to alert workers of the potential danger. Such incident also involves investigating the cause of the spill or leak and implementing measures to prevent future occurrences.
- A New Chemical Substance: Introducing a new chemical into the workplace is a complex process. A thorough hazard identification involves understanding the chemical's properties, potential health effects and necessary protective measures. Safety data sheets provide valuable information, but hazard identification includes assessing the chemical's interaction with other substances, determining safe storage and handling procedures and training employees on emergency responses in case of exposure.
- Inadequate Personal Protective Equipment: PPE is essential to protect workers. Inadequate PPE is a hazard as it exposes workers to risks that could otherwise be mitigated. Identifying these hazards involves assessing the tasks performed, the hazards present, and the suitability of the PPE provided.
- Psychological Stressors: Workplace stress is a hazard that can lead to physical and mental health issues. Identifying psychological stressors goes beyond the physical environment to the organizational culture and work demands. It includes workload, deadlines, interpersonal relationships and support systems. Mitigating actions may be management programs, promoting work-life balance and fostering an inclusive work environment.
Hazard identification is a critical component of workplace safety. It is not just about recognizing the hazards that are present but also about understanding the potential hazards that could arise.
