Risk Evaluation

Risk Evaluation
"""A risk assessment is what?

The process or procedure where you: Identify hazards and risk variables that could have a negative impact is known as risk assessment (hazard identification). Analyze and assess the risk brought on by the hazard (risk analysis, and risk evaluation). Find appropriate strategies to reduce the risk or, if the danger cannot be reduced, remove it (risk control). A risk assessment is a detailed examination of your workplace to find any elements, circumstances, procedures, etc. that could be harmful, especially to humans. Following identification, you assess the risk's likelihood and seriousness. You can then decide what steps need to be taken to successfully eliminate or control the harm once this assessment has been made. The following phrases are used in the CSA Standard Z1002 ""Occupational health and safety - Hazard identification and elimination and risk assessment and control"": Hazard identification, risk analysis, and risk evaluation are all parts of risk assessment. Identification of risks is the process of locating, cataloging, and classifying dangers. Risk analysis is a procedure for understanding hazards' characteristics and estimating risk levels. (1) Risk analysis serves as a foundation for risk assessment and choices on risk management. (2) Information can be in the form of recent and archival facts, theoretical analysis, well-informed opinions, and stakeholder concerns. (3) Risk estimation is a component of risk analysis. Comparing an estimated risk to predetermined risk criteria in order to assess the importance of the risk. Risk control is the implementation of choices made after risk evaluation. Note: Monitoring, re-evaluation, and decision-compliance can all be part of risk control. Please refer to the OSH Answers page Hazard and Risk for definitions and more details on what these terms mean.

What makes risk assessment crucial?

Risk evaluations are crucial because they are a crucial component of a management strategy for occupational health and safety. They aid in: Raising people's awareness of risks and hazards. Decide who might be at risk (e.g., employees, cleaners, visitors, contractors, the public, etc.). Find out if a control program is necessary for a specific hazard. Check to see if the current control measures are sufficient or if more needs to be done. Avoid illnesses or injuries, especially if you can, during the design or planning stages. Prioritize the risks and preventative measures. with any applicable legal requirements.

What is the purpose of risk analysis?

The goal of the risk assessment process is to identify hazards, remove them when needed, or reduce the level of risk they pose by implementing management measures. You've made the workplace safer and healthier by doing this. The intention is to attempt to respond to the following queries: What is possible and under what conditions? What are the potential repercussions? How likely is it that the potential outcomes will materialize? Is the danger successfully controlled, or do we need to take more steps?

When should a risk analysis be performed?

A risk assessment may be necessary for a variety of reasons, including: before introducing new procedures or practices. When new knowledge about harm becomes available, when products, machines, tools, or equipment change, or before adjustments are made to current processes or activities. when dangers are discovered.

How should a risk assessment be prepared for?

Generally, decide: What will be the scope of your risk assessment (e.g., be specific about what you are assessing such as the lifetime of the product, the physical area where the work activity takes place, or the types of hazards). the necessary resources (e.g., train a team of individuals to carry out the assessment, the types of information sources, etc.). Which risk analysis techniques will be employed (e.g., how exact the scale or parameters need to be in order to provide the most relevant evaluation). Who are the parties that are involved? (e.g., manager, supervisors, workers, worker representatives, suppliers, etc.). What applicable organizational policies and procedures, as well as any laws, rules, codes, or standards that may be applicable in your jurisdiction.

How is a risk analysis carried out?

An expert or team of experts who are knowledgeable about the situation being investigated should conduct assessments. Supervisors and employees who work on the process under evaluation should be included, either as members of the team or as sources of information, as they have the most familiarity with the operation. To do an assessment, you should generally: Determine dangers. Determine the possibility and magnitude of harm, such as an injury or illness, from occurring. Think about both routine operational circumstances and unusual occurrences like maintenance, closures, power outages, emergencies, severe weather, etc. Review all available health and safety information about the hazard such as Safety Data Sheet (SDS), manufacturers literature, information from reputable organizations, results of testing, workplace inspection reports, records of workplace incidents (accidents), including information about the type and frequency of the occurrence, illnesses, injuries, near misses, etc. Know what your jurisdiction's minimal legal requirements are. Determine the steps required to reduce the risk or remove the hazard utilizing the hierarchy of risk control strategies. Evaluate to confirm if the hazard has been eliminated or if the risk is appropriately controlled. Monitor to make sure the control continues to be effective. Keep any documents or records that may be necessary. Documentation may include detailing the process used to assess the risk, outlining any evaluations, or detailing how conclusions were made. When doing an assessment, also take into account: The methods and procedures used in the processing, use, handling or storage of the substance, etc. The actual and the potential exposure of workers (e.g., how many workers may be exposed, what that exposure is/will be, and how often they will be exposed). The measures and procedures necessary to control such exposure by means of engineering controls, work practices, and hygiene practices and facilities. The duration and frequency of the task (how long and how often a task is done). The location where the task is done. The machinery, tools, materials, etc. that are used in the operation and how they are used (e.g., the physical state of a chemical, or lifting heavy loads for a distance). Any possible interactions with other activities in the area and if the task could affect others (e.g., cleaners, visitors, etc.). The lifecycle of the product, process or service (e.g., design, construction, uses, decommissioning). The education and training the workers have received. How a person would react in a particular situation (e.g., what would be the most common reaction by a person if the machine failed or malfunctioned). It is important to remember that the assessment must take into account not only the current state of the workplace but any potential situations as well. By determining the level of risk associated with the hazard, the employer, and the health and safety committee (where appropriate), can decide whether a control program is required and to what level. See a sample risk assessment form.

How are the hazards identified?

Overall, the goal is to find and record possible hazards that may be present in your workplace. It may help to work as a team and include both people familiar with the work area, as well as people who are not - this way you have both the experienced and fresh eye to conduct the inspection. In either case, the person or team should be competent to carry out the assessment and have good knowledge about the hazard being assessed, any situations that might likely occur, and protective measures appropriate to that hazard or risk. To be sure that all hazards are found: Look at all aspects of the work. Include non-routine activities such as maintenance, repair, or cleaning. Look at accident / incident / near-miss records. Include people who work off site either at home, on other job sites, drivers, teleworkers, with clients, etc. Look at the way the work is organized or done (include experience of people doing the work, systems being used, etc). Look at foreseeable unusual conditions (for example: possible impact on hazard control procedures that may be unavailable in an emergency situation, power outage, etc.). Determine whether a product, machine or equipment can be intentionally or unintentionally changed (e.g., a safety guard that could be removed). Review all of the phases of the lifecycle. Examine risks to visitors or the public. Consider the groups of people that may have a different level of risk such as young or inexperienced workers, persons with disabilities, or new or expectant mothers. It may help to create a chart or table such as the following: Example of Risk Assessment Task Hazard Risk Priority Control Delivering product to customers Drivers work alone May be unable to call for help if needed Drivers have to occasionally work long hours Fatigue, short rest time between shifts Drivers are often in very congested traffic Increased chance of collision Longer working hours Drivers have to lift boxes when delivering product Injury to back from lifting, reaching, carrying, etc.

How do you know if the hazard will cause harm (poses a risk)?

Each hazard should be studied to determine its' level of risk. To research the hazard, you can look at: Product information / manufacturer documentation. Past experience (knowledge from workers, etc.). Legislated requirements and/or applicable standards. Industry codes of practice / best practices. Health and safety material about the hazard such as safety data sheets (SDSs), research studies, or other manufacturer information. Information from reputable organizations. Results of testing (atmospheric or air sampling of workplace, biological swabs, etc.). The expertise of an occupational health and safety professional. Information about previous injuries, illnesses, near misses, incident reports, etc. Observation of the process or task. Remember to include factors that contribute to the level of risk such as: The work environment (layout, condition, etc.). The systems of work being used. The range of foreseeable conditions. The way the source may cause harm (e.g., inhalation, ingestion, etc.). How often and how much a person will be exposed. The interaction, capability, skill, experience of workers who do the work.

How are risks ranked or prioritized?

Ranking or prioritizing hazards is one way to help determine which risk is the most serious and thus which to control first. Priority is usually established by taking into account the employee exposure and the potential for incident, injury or illness. By assigning a priority to the risks, you are creating a ranking or an action list. There is no one simple or single way to determine the level of risk. Nor will a single technique apply in all situations. The organization has to determine which technique will work best for each situation. Ranking hazards requires the knowledge of the workplace activities, urgency of situations, and most importantly, objective judgement. For simple or less complex situations, an assessment can literally be a discussion or brainstorming session based on knowledge and experience. In some cases, checklists or a probability matrix can be helpful. For more complex situations, a team of knowledgeable personnel who are familiar with the work is usually necessary. As an example, consider this simple risk matrix. Table 1 shows the relationship between probability and severity. Severity ratings in this example represent: High: major fracture, poisoning, significant loss of blood, serious head injury, or fatal disease Medium: sprain, strain, localized burn, dermatitis, asthma, injury requiring days off work Low: an injury that requires first aid only; short-term pain, irritation, or dizziness Probability ratings in this example represent: High: likely to be experienced once or twice a year by an individual Medium: may be experienced once every five years by an individual Low: may occur once during a working lifetime The cells in Table 1 correspond to a risk level, as shown in Table 2. These risk ratings correspond to recommended actions such as: Immediately dangerous: stop the process and implement controls High risk: investigate the process and implement controls immediately Medium risk: keep the process going; however, a control plan must be developed and should be implemented as soon as possible Low risk: keep the process going, but monitor regularly. A control plan should also be investigated Very low risk: keep monitoring the process Let's use an example: When painting a room, a step stool must be used to reach higher areas. The individual will not be standing higher than 1 metre (3 feet) at any time. The assessment team reviewed the situation and agrees that working from a step stool at 1 m is likely to: Cause a short-term injury such as a strain or sprain if the individual falls. A severe sprain may require days off work. This outcome is similar to a medium severity rating. Occur once in a working lifetime as painting is an uncommon activity for this organization. This criterion is similar to a low probability rating. When compared to the risk matrix chart (Table 1), these values correspond to a low risk. The workplace decides to implement risk control measures, including the use of a stool with a large top that will allow the individual to maintain stability when standing on the stool. They also determined that while the floor surface is flat, they provided training to the individual on the importance of making sure the stool's legs always rest on the flat surface. The training also included steps to avoid excess reaching while painting.

What are methods of hazard control?

Once you have established the priorities, the organization can decide on ways to control each specific hazard. Hazard control methods are often grouped into the following categories: Elimination (including substitution). Engineering controls. Administrative controls. Personal protective equipment. For more details, please see the OSH Answers Hazard Control.

Why is it important to review and monitor the assessments?

It is important to know if your risk assessment was complete and accurate. It is also essential to be sure that any changes in the workplace have not introduced new hazards or changed hazards that were once ranked as lower priority to a higher priority. It is good practice to review your assessment on a regular basis to make sure your control methods are effective.

What documentation should be done for a risk assessment?

Keeping records of your assessment and any control actions taken is very important. You may be required to store assessments for a specific number of years. Check for local requirements in your jurisdiction. The level of documentation or record keeping will depend on: Level of risk involved. Legislated requirements. Requirements of any management systems that may be in place. Your records should show that you: Conducted a good hazard review. Determined the risks of those hazards. Implemented control measures suitable for the risk. Reviewed and monitored all hazards in the workplace."""
