Overview of Hazard Analysis

OSHA defines hazard as any situation, source, or act that has a potential to cause harm such as ill health or injury, or even a combination of the two. Hazards are the primary cause for occupational safety and health problems. All employers should identify and remove all potential hazards from the workplace. To keep the workplace safe, employers must conduct hazard analysis. Hazard analysis is the process of identifying hazards that have the potential to arise from a system or environment, documenting their unwanted consequences, and analyzing their underlying causes. The hazard analysis process starts in the early stages of a project with a Preliminary Hazard Analysis (PHA) and continues throughout the product’s life cycle.

The objectives of hazard analysis are threefold:

  • To identify hazards of the equipment under control and the control system for all circumstances, including fault conditions and misuse.
  • To identify and analyze causes leading to the hazardous events identified.
  • To determine potential risks.

Hazard analysis is performed for one of the following reasons:

  • Examination of new system development to identify and analyze potential hazards and consequently control or eliminate them.
  • Examination of the existing system to identify and analyze hazards to improve safety, create new safety management policy, train personnel, increase motivation for safety and efficiency of operation among employees.
  • Examination of an existing system to showcase the safety commitment of the organization to its customer, government, and the public through certification

Hazard analysis is a continuous process that has to be performed to mitigate hazards that can be introduced at any stage from requirements, design, development, product testing, installation, commissioning, operation, system maintenance, and disposal of a system. Some of the events that could initiate hazard analysis include:

  • Concept definition
  • Reviews of requirement, design, design change
  • Evaluation of different plans including installation and commissioning, operating and support, decommissioning

By conducting hazard analysis, organisations can:

  • Improve the quality of the product
  • Reduce down time of processes
  • Enhance process or procedure
  • Promotes safety feeling among employees

Overview of Hazard Assessment

Hazard assessment is an essential component of risk management that helps identify, evaluate, and mitigate potential hazards for workplace safety, environmental protection, emergency planning, and public health. The hazard assessment process is categorized into three steps: identification, evaluation, and control.

  • Hazard Identification: This involves identifying all the potential hazards, including physical, biological, ergonomic, and psychosocial hazards.
  • Hazard Evaluation: The next step is to prioritize hazards based on their level of risk and determine which require immediate attention.
  • Hazard Control: In this step, safety leaders prepare practical and cost-effective hazard mitigation strategies to reduce or eliminate the identified risks. These measures can be as simple as mandating PPE gears to implement engineering or administrative controls.
Overview of hazard assessment

OSHA and Hazard Assessment

Hazard assessment is part of the Occupational Safety and Health Administration (OSHA) regulations in the United States that outline specific requirements to ensure workplace safety. OSHA mandates that employers assess and address workplace hazards systematically to protect workers from potential harm. Compliance with OSHA's hazard assessment requirements is critical for maintaining workplace safety and preventing injuries and illnesses. Employers should be familiar with OSHA regulations and guidelines related to hazard assessment and implement a robust hazard assessment program to protect the health and safety of their workers.

When it comes to hazard assessment, OSHA emphasizes three important processes - training, documentation, and hazard review.

  • Training:

    Employers must ensure employees are trained in hazard identification, evaluation, and control measures relevant to their job tasks. Effective communication of hazard assessment findings, controls, and procedures to workers ensures their understanding and compliance.

  • Documentation:

    OSHA requires employers to document hazard assessments, including hazard identification, evaluation, and control measures. Documentation should be thorough, accurate, and readily available for employees, OSHA inspectors, and other stakeholders to review.

  • Review:

    Regular reviews are also essential to ensure that the risk management measures remain relevant and effective. Changes in the workplace, regulations, or technology may affect the hazards and risks associated with a particular workplace, requiring reassessment and modification of mitigation strategies.

Fundamentals of Hazard Assessment

To perform a hazard assessment, one must be aware of the different types of hazards. OSHA lists five different types of workplace hazards. They are:

safety hazard assessment
Safety hazards

Includes any substance, object, or condition that has the potential to harm workers. Examples of safety hazards include spills on shop floor, falls from height, machines with moving parts, electrical hazards, walkway blockages, among others.

chemical hazard assessment
Chemical hazards

Which is caused by exposure to acids, flammable liquids, silica dust, pesticides, carbon monoxide, pesticides. The exposure can be in any form such as vapors, fumes, gases, or liquids.

biological hazard assessment
Biological hazards

Include exposure to animals or other infection-prone material such as fungi, blood, mold, viruses, or animal droppings.

physical hazard assessment
Physical hazards

Can harm workers with or without direct contact through radiation, exposure to extreme temperatures, surrounded by loud noise, or long hours under the sun.

ergonomic hazard assessment
Ergonomic hazards

That can occur due to repetitive work, tasks that puts the body under certain strain or even the type of work. As the problem develops over time, this type of hazard is difficult to spot.

Hazard assessments help identify, evaluate, and manage risk associated with hazards. Hazard assessments also help adopt different hazard controls in the design process. Depending on the nature of the process, manufacturers can use different hazard controls.

There are three fundamental parts to hazard assessment: prepare, implement, and learn.

Prepare

  • Define the scope of hazard assessment.

  • Assemble the team with clearly defined roles, expectations, and responsibilities.

  • Familiarise with common hazards that can be encountered in research activities.

Implement

Learn

  • Research past injuries, accidents, and near misses.

  • Understand the new equipment, facilities, and personnel for new hazards and prepare new controls to apply.

  • Conduct regular visits, revise and update safety documents and protocols to prevent hazard encounters.

what are the limitations of hazard analysis

What are the Limitations of Hazard Analysis?

The success of hazard analysis is based on the committee. Members of the committee must have relevant experience and understanding of the processes. Any lack thereof could affect the effectiveness of the analysis. Although hazard analysis is a continuous process, there are many limitations to it. Some of them are:

  • Unavailability of the hazard analysis method to identify all accident scenarios, hazards, and consequences
  • Assumption based hazard analysis method can yield different results with a different set of parameters
  • The analysis is based on the experience of participants
  • Results of a hazard analysis can be challenging to manage and interpret

How to Conduct Hazard Analysis?

Broadly, there are two types of hazards – realized and unrealized. While a realized hazard can be identified from experience, an unrealized hazard has no previous occurrence but can be identified by observing and analyzing the environment or by studying the failed models of equipment.

There are many different hazard analysis techniques. Some of them are:

  • Function Failure Analysis
  • Cause-consequence Diagrams
  • Failure Modes and Effects Analysis
  • Hazard and Operability Studies
  • Fault Tree Analysis
  • Event Tree Analysis
  • Job Hazard Analysis
A hazard analysis includes the following steps:
  • Define objectives of the system, procedure, and process.
  • Identify the various hazards based on the complexities of the process through different data points such as historical data, standards and code of practice, and experimental results.
  • Research various scenarios and categorize them based on the potential to become a hazard.
  • Determine the probability of an accident in risk assessment using source models.
  • Conclude and decide if the risk is acceptable. If acceptable, implement the process. Else, restart the hazard analysis.
While conducting hazard analysis, follow these best practices:
  • Involve employees to get their unique knowledge and understanding. This helps minize oversights and improves employee morale.
  • Review history of accidents and other occupational illnesses as they act as indicators to existing hazards.
  • Conduct preliminary review of jobs to understand the potential risk involved and brainstorm hazard controls.
  • Based on the severity of the risk potential, rank the jobs and set priorities for hazard analysis.
  • Create an outline of tasks or steps that needs to be taken as part of hazard analysis as this helps collect information accurately.

What is Process Hazard Analysis mandated by OSHA?

OSHA mandates a Process Hazard Analysis (PHA) for all industrial processes that use hazardous chemicals. PHA identifies and analyzes data that will allow employers and employees to make decisions related to improving safety and reducing the repercussions of an unplanned release of hazardous chemicals into nature. PHA’s purpose is to identify the implications of scenarios that can cause fires, explosions, chemical spills, or the release of toxic chemicals. There are various methods for conducting PHA:

  • A What-if Study where review consists of what-if questions based on the processes.

  • A Checklist to support a what-if study of a more complicated process.

  • A formal structured method, namely Hazard and Operability Study (HAZOP) that analyzes possible deviations in the design conditions.

hazard assessment mandated by OSHA

  • A systematic study called Failure Mode and Effects Analysis (FMEA) includes a diagram of the operation and details all components that have the potential to fail and, in turn, affect the safety of the operation.

  • A qualitative or quantitative Fault Tree Analysis that focuses on all the potential undesirable outcomes, like toxic gas release or explosion that can arise from a specific initiating event.

  • An appropriate equivalent method.
