By the end of this guide, you will clearly understand how to conduct a field level hazard assessment effectively, empowering you to create a safer workplace for yourself and others. Let's dive in and start our journey toward a hazard-free work environment.


Understanding the Importance of Conducting a Field Level Hazard Assessment

A field level hazard assessment is a critical tool in ensuring workers' safety and preventing workplace accidents and injuries. By conducting a thorough assessment, organizations can identify potential hazards, evaluate the level of risk associated with each hazard, and implement control measures to mitigate those risks. This proactive approach significantly reduces the chances of accidents occurring and helps create a safe and secure working environment.

One of the critical reasons why conducting a field level hazard assessment is essential is the legal and regulatory requirements. Canada has strict laws and regulations that mandate employers to conduct regular hazard assessments to ensure the safety of their employees. Failure to follow with these requirements can result in hefty fines, legal consequences, and reputational damage for the organization.

Furthermore, a field level hazard assessment helps organizations identify potential hazards that may not be immediately apparent. It allows them to discover hidden risks and take appropriate measures to minimize or eliminate them. By addressing these hazards proactively, organizations can prevent accidents, injuries, and even fatalities, protecting their employees from harm and saving lives.


Key Components of a Field Level Hazard Assessment

A field level hazard assessment typically consists of several vital components that work together to evaluate potential risks comprehensively. These components include hazard identification, risk assessment, control measures development, control measures implementation, and monitoring and review.

Step 1: Identifying Potential Hazards

The first step in conducting a field level hazard assessment is identifying potential hazards in the work area. This involves a thorough examination of the workplace, equipment, materials, and processes. It is essential to include employees who have firsthand knowledge and experience in the work area to ensure all hazards are identified. Hazard identification can be done through various methods, such as visual inspections, employee interviews, reviewing incident reports, and analyzing historical data.

Step 2: Assessing the Level of Risk

Once potential hazards are identified, the next step is to assess the level of risk associated with each hazard. This involves considering the likelihood of an incident happening and the severity of the potential consequences. Risk assessment can be done using qualitative or quantitative methods, depending on the complexity of the hazards and the available resources. The goal is to prioritize hazards based on their risk level, so control measures can be implemented effectively.

Step 3: Developing Control Measures

After assessing the level of risk, the next step is to develop control measures that will effectively mitigate the identified hazards. Control measures can be categorized into four main types: elimination, substitution, engineering controls, and administrative controls. Control measures should be selected based on their effectiveness, feasibility, and cost. It is essential to involve employees and relevant stakeholders in the development of control measures to ensure their practicality and acceptance.

Step 4: Implementing Control Measures

Once control measures are developed, they need to be implemented in the workplace. This involves clearly communicating the control measures to all employees, providing necessary training and resources, and ensuring proper implementation. It is crucial to monitor the implementation process and address any challenges or barriers that may arise. Regular communication and feedback are essential to successful implementation.

Step 5: Monitoring and Reviewing the Effectiveness of Control Measures

After control measures are implemented, monitoring their effectiveness and their impact on the hazards identified is essential. This involves ongoing monitoring of the workplace, conducting inspections and audits, and seeking feedback from employees. If control measures are found to be ineffective or new hazards are identified, appropriate adjustments should be made to ensure continuous improvement in the safety measures.


Practical Example: Conducting a Field Level Hazard Assessment on a Construction Site

To illustrate the process of conducting a field level hazard assessment, let's consider a practical example in a construction site. In this scenario, we will focus on identifying hazards and implementing control measures to ensure the safety of workers involved in excavation work.

Hazard Identification

During the initial assessment of the construction site, potential hazards are identified, such as uneven ground, unstable soil, underground utilities, heavy machinery, and working at heights. This is done through site inspections, reviewing construction plans, and consulting with workers who have expertise in excavation work.

Risk Assessment

Once the hazards are identified, a risk assessment is conducted to evaluate the level of risk associated with each hazard. For example, the risk of a worker falling from a height while working on a scaffolding platform is assessed as high due to the severity of potential consequences. Similarly, the risk of workers encountering underground utilities during excavation is assessed as moderate due to the likelihood and potential consequences.

Control Measures Development

Based on the risk assessment, control measures are developed to mitigate the identified hazards. For example, to address the risk of falls from heights, control measures may include:

  • The installation of guardrails.
  • The use of safety harnesses.
  • Providing proper training on working at heights.

To address the risk of encountering underground utilities, control measures may include conducting utility locates, implementing safe digging practices, and providing workers with appropriate personal protective equipment.

Control Measures Implementation

Once the control measures are developed, they are implemented on the construction site. This involves training workers on the new safety procedures, providing them with necessary equipment and resources, and ensuring compliance with the control measures. Regular inspections and audits are conducted to monitor the implementation process and address any issues or concerns.

Monitoring and Reviewing

After the control measures are implemented, continuous monitoring and reviewing are essential to ensure their effectiveness. This includes ongoing inspections of the construction site, conducting toolbox talks to reinforce safety procedures, and seeking worker feedback. If any new hazards are identified, or control measures are found to be ineffective, appropriate adjustments are made to improve the safety measures.


Common Challenges and How to Overcome Them

Conducting a field level hazard assessment can present various challenges that organizations need to overcome to ensure the effectiveness of the process. Some common challenges include employee resistance, lack of resources, inadequate training, and the dynamic nature of work environments. To overcome these challenges, it is essential to:

  1. Involve employees in the hazard assessment process and address their concerns and feedback.
  2. Allocate adequate resources in terms of time and budget to conduct a thorough assessment.
  3. Provide comprehensive training to employees on hazard identification, risk assessment, and control measures.
  4. Regularly review and update the hazard assessment process to adapt to changing work environments and emerging risks.



Conducting a field level hazard assessment is a critical step in guaranteeing the safety of workers and creating a hazard-free work environment. By following a systematic approach, organizations can identify potential hazards, assess their level of risk, and implement control measures to mitigate those risks.
