What are the factors that must include the review in a proper risk assessment of chemicals?

After you've evaluated the risks of each hazard, you should take appropriate action to eliminate or minimise those risks. Reasonably practicable measures should be taken to protect people from harm.

You should select your risk control measures based on the Hierarchy of Control. Upstream risk controls (e.g. elimination, substitution and engineering controls) are more effective in reducing or controlling risk, and should be considered first.

Above: Hierarchy of Control.

You should consider using a combination of control measures from the Hierarchy of Control as no single measure is usually sufficient to control the risk. For example, engineering controls need to be implemented together with administrative controls such as training and safe work procedures to address the hazard sufficiently.

Personal protective equipment (PPE) should be explored only after upstream risk controls have been considered, as a short-term contingency during emergency, maintenance, repair or as an additional protective measure against residual risks. The effectiveness of PPE depends greatly on whether it is chosen and fitted correctly, worn at all times and maintained properly.

For hazards that cannot be controlled immediately, interim control measures should be implemented while establishing longer term measures to reduce the risk level. Work should not start if the risk remains high.

Risk assessment is one of the major components of a risk analysis. Risk analysis is a process with multiple steps that intends to identify and analyze all of the potential risks and issues that are detrimental to the business. This is an ongoing process that gets updated when necessary. These concepts are interconnected and can be used individually.

Risk communication is the process of exchanging information and opinion on risk to concerned parties. Risk management is the proactive control and evaluation of threats and risks to prevent accidents, uncertainties and errors. Together with risk assessment, these are all vital elements that help make informed decisions such as mitigating risks.

Why Is Risk Assessment Important?

Identifying hazards by using the risk assessment process is a key element when ensuring the health and safety of your employees and customers. OSHA requires businesses to conduct risk assessments. According to regulations set by OSHA, assessing hazards or potential risk will determine the personal protective gears and equipment a worker may need for their job. There are guidelines available for different industries since present types of possible risks may vary, an example of this is agribusinesses. Unique risks for this industry include manure storage, tractor operation, animal handling, behavior, and health.

The Environmental Protection Agency (EPA) of the US specializes in assessing hazards related to humans and its environmental receptors such as animals, chemicals, and other ecological factors. While in the UK, conducting risk assessments are a legal requirement as stated in the Health and Safety at Work Act. The specific regulation under this law can be retrieved from the Management of Health and Safety at Work Regulations Section.

The gravity of hazard identifications is clear with all these organizations and governments requiring risk assessments at work. Prevent and reduce risks to save lives and to ensure that the workplace stays as a safe space.

Risk Analysis Framework

When Do You Perform a Risk Assessment?

Beyond complying with legislative requirements, the purpose of risk assessments are to eliminate operational risks and improve the overall safety of the workplace. It is employers responsibility to perform risk assessments when:

• new processes or steps are introduced in the workflow;
• changes are made to the existing processes,
• equipment, and tools; or new hazards arise.

Risk assessments are also performed by auditors when planning an audit procedure for a company.

Difference Between Risk Assessment and Job Safety Analysis (JSA)

Risk assessments are often confused with a Job Safety Analysis (JSA) or Job Hazard Analysis (JHA). The key difference between a risk assessment and a JSA is scope. Risk assessments assess safety hazards across the entire workplace and are oftentimes accompanied with a risk matrix to prioritize hazards and controls. Whereas a JSA focuses on job-specific risks and are typically performed for a single task, assessing each step of the job.

3 Types

While the exact details of risk assessments may vary greatly across different industries, HSE distinguishes three general risk assessment types:

Large Scale Assessments

This refers to risk assessments performed for large scale complex hazard sites such as the nuclear, and oil and gas industry. This type of assessment requires the use of an advanced risk assessment technique called a Quantitative Risk Assessment (QRA).

Required specific assessments

This refers to assessments that are required under specific legislation or regulations, such as the handling of hazardous substances (according to COSHH regulations, 1998) and manual handling (according to Manual Handling Operations Regulations, 1992).

General assessments

This type of assessment manages general workplace risks and is required under the management of legal health and safety administrations such as OSHA and HSE.

Examples

Risk assessments are essential to identify hazards and risks that may potentially cause harm to workers. There are a variety of risk assessments used across different industries tailoring specific needs and control measures. Here are common risk assessment examples:

• Health and Safety Risk Assessment – a type of risk assessment used by safety managers to determine health and safety risks associated with the job, work environment, and current processes. Hazards can be identified as biological, chemical, energy, environmental, and the like.  
• Workplace Risk Assessment – performed by office managers and school administrators, this tool helps ensure that a workplace is free from health and safety threats. This assessment also helps boost employee morale and productivity.
• Fall Risk Assessment – performed by nursing staff of aged care units or centers to evaluate the possibility of falling. This checklist will ensure that the facilities, equipment, and other factors are safe for elderly patients.
• Construction Risk Assessment – a vital assessment used in the construction site to help safety teams implement corrective measures and stakeholders comply with safety regulations.

Risk assessments can be seen as a regulatory paperwork burden, but understanding the reason and purpose of a risk assessment will help your team identify, prioritize and control hazards in your workplace.

Planning

Risk assessments should be carried out by competent persons who are experienced in assessing hazard injury severity, likelihood, and control measures. To start off, good planning will be essential in order to implement a risk assessment effectively. Consider the following 4 elements as stated by the Occupational Safety and Health Administration (OSHA):

1. What is your scope?
   Determining the scope when planning your risk assessment can help you figure out what resources you would need. Be specific about what you’re assessing. Are you assessing a product? An organizational process? Or a workplace area?
2. What resources do you need?
   Determine the kind of training, tools, and equipment your team needs to effectively carry out the risk assessment. You should also determine the risk analysis measures you are going to use and know why they are the best choice for your purpose.
3. Who is involved?
   Note the personnel involved in your risk assessment planning and implementation. They could be managers, supervisors, workers, or suppliers. This helps you identify additional resources that can help you improve the effectiveness of your risk assessment.
4. What laws, regulations, and internal policies do you need to comply with?
   Non-compliance could lead to hefty fines and other offenses that can spell trouble for your operation. Determine the laws, regulations, codes, standards, and internal policies you need to consider when conducting your risk assessment.

By determining all of these, you can create a solid foundation for an effective risk assessment. Once you’ve planned out your risk assessment, you can proceed with performing the risk assessment. A risk assessment is performed in 5 steps or stages.

5 Steps

1. Identify hazards

Survey the workplace and look at what could reasonably be expected to cause harm. Identify common workplace hazards. Check manufacturers or suppliers instructions or data sheets for any obvious hazards. Review previous accident and near-miss reports. Efficiently identify hazards by using a hazard identification checklist. This ensures everything is covered during risk assessment and hazard identification which prevents risks from escalating.Hazards and risks are sometimes used interchangeably; however, they actually refer to two different elements of a potential incident. A hazard is something that has the potential of causing harm to people, property, or the environment, while risk is the likelihood of a hazard to actually cause harm or damage under defined circumstances.

2. Evaluate the risks

To evaluate a hazard’s risk, you have to consider how, where, how much and how long individuals are typically exposed to a potential hazard. Assign a risk rating to your hazards with the help of a risk matrix. Using a risk matrix can help measure the level of risk per hazard by considering factors such as the likelihood of occurrence, and severity of potential injuries. Meanwhile, performing an environmental analysis lets you gauge potential risks and their impacts on your business environment.

3. Decide on control measure to implement

After assigning a risk rating to an identified hazard, it’s time to come up with effective controls to protect workers, properties, civilians, and/or the environment. Follow the hierarchy of controls in prioritizing implementation of controls.

4. Document your findings 

It is important to keep a formal record of risk assessments. This can help your organization keep track of hazards, risk, and control measures. Documentation may include a detailed description of the process in assessing the risk, an outline of evaluations, and detailed explanations on how conclusions were made.
Use a risk assessment template to document your findings. Get started with iAuditor’s free risk assessment templates that you can use on your mobile device while on-site. Share your report and findings with key parties who can implement changes.

5. Review your assessment and update if necessary

Follow up with your assessments and see if your recommended controls have been put in place. If the conditions in which your risk assessment was based on change significantly, use your best judgment to determine if a new risk assessment is necessary.

There are options on the tools and techniques that can be seamlessly incorporated into a business’ process. The four common risk assessment tools are: risk matrix, decision tree, failure modes and effects analysis (FMEA), and bowtie model. Other risk assessment techniques include what-if analysis, failure tree analysis, and hazard operability analysis.

How to use a Risk Matrix?

A risk matrix is often used during a risk assessment to measure the level of risk by considering the consequence/ severity and likelihood of injury to a worker after being exposed to a hazard. The two measures can then help determine the overall risk rating of the hazard. Two key questions to ask when using a risk matrix should be:

1. Consequences: How bad would the most severe injury be if exposed to the hazard?
2. Likelihood: How likely is the person to be injured if exposed to the hazard?

The most common types are the 3×3 risk matrix, 4×4 risk matrix, and 5×5 risk matrix.

How to Assess Consequences?

In assessing the consequences of a hazard, the first question should be asked “If a worker is exposed to this hazard, how bad would the most probable severe injury be?”. For this consideration we are presuming that a hazard and injury is inevitable and we are only concerned with its severity.

It is common to group the injury severity and consequence into the following four categories:

• Fatality – leads to death
• Major or serious injury – serious damage to health which may be irreversible, requiring medical attention and ongoing treatment
• Minor injury – reversible health damage which may require medical attention but limited ongoing treatment). This is less likely to involve significant time off work.
• Negligible injuries – first aid only with little or no lost time.

To illustrate how this can be used in the workplace we will use the example of a metal shearing task. A hazard involved could include a piece of metal flying out of the equipment while in use. In this example the probable most severe injury would be “Major or Serious Injury” with the possibility of bruising, breakage, finger amputation.

How to Assess Likelihood?

In assessing the likelihood, the question should be asked “If the hazard occurs, how likely is it that the worker will be injured?”. This should not be confused with how likely the hazard is to occur. It is common to group the likelihood of a hazard causing worker injury into the following four categories:

• Very likely – exposed to hazard continuously.
• Likely – exposed to hazard occasionally.
• Unlikely – could happen but only rarely.
• Highly unlikely – could happen, but probably never will.

In our metal shearing example the question should not be “How likely is the machine expected to fail?” but instead “When the machine fails and causes metal to fly out, how likely is the worker expected to be injured?”. If in our example we observe a safe distance between the machine and worker and proper PPE being worn, we could rate it as “Unlikely” given our observations

We recommend OSHA’s great learning resources in understanding how to assess consequence and likelihood in your risk assessments.

Risk Assessment Training: Achieving a Culture of Safety

“Safety has to be everyone’s responsibility… everyone needs to know that they are empowered to speak up if there’s an issue.” – Captain Scott Kelly, at the SafetyCulture Virtual Summit.

Thinking about safety shouldn’t stop at the completion of a risk assessment. Embody a safety culture, that way employees are empowered to be greatly aware and conscious of their safety as they do their best work. A hazard identification and risk assessment training can help your organization achieve that.

A good and effective risk assessment training should orient new and existing employees on various hazards and risks that they may potentially encounter. It should also be able to walk them through safety protocols. When everyone is on the same page, managing risks becomes easy.

Conducting or providing training shouldn’t be a pain. With today’s technology, many mobile applications allow you to transform training into engaging and bite sized lessons. Below are a few courses we picked out that can be beneficial for you in getting started:

• Safety in the Workplace by Edapp
• New Hire Safety Orientation Lessons
