The Health and Safety Executive's Five steps to risk assessment. Step 1: Identify the hazards. Walk around your venue and look at what could reasonably be. A risk assessment is an important step in protecting your workers and your business, as well as complying with the law. It helps you focus on the risks that. OIE International Animal Health Code. • The risk assessment includes the following steps: – Release assessment: description of biological.
This restricts the range of hazards to be considered. This is followed by identification of visible and implied hazards that may threaten the project, and determining the qualitative nature of the potential adverse consequences of each hazard. Without a potential adverse consequence, there is no hazard.
It is also necessary to identify the potential parties or assets which may be affected by the threat, and the potential consequences to them if the hazard is activated. If the consequences are dependent on dose, i. This is the general case for many health hazards where the mechanism of injury is toxicity or repetitive injury, particularly where the effect is cumulative. For other hazards, the consequences may either occur or not, and the severity may be extremely variable even when the triggering conditions are the same.
This is typical of many biological hazards as well as a large range of safety hazards. Exposure to a pathogen may or may not result in actual infection, and the consequences of infection may also be variable. Similarly a fall from the same place may result in minor injury or death, depending on unpredictable details. In these cases estimates must be made of reasonably likely consequences and associated probability of occurrence.
In cases where statistical records are available they may be used to evaluate risk, but in many cases there are no data or insufficient data available to be useful.
Mathematical or experimental models may provide useful input. The complexity of this step in many contexts derives mainly from the need to extrapolate results from experimental animals e. In addition, the differences between individuals due to genetics or other factors mean that the hazard may be higher for particular groups, called susceptible populations.
An alternative to dose-response estimation is to determine a concentration unlikely to yield observable effects, that is, a no effect concentration.
In developing such a dose, to account for the largely unknown effects of animal to human extrapolations, increased variability in humans, or missing data, a prudent approach is often adopted by including safety or uncertainty factors in the estimate of the "safe" dose, typically a factor of 10 for each unknown step. Exposure Quantification, aims to determine the amount of a contaminant dose that individuals and populations will receive, either as a contact level e.
This is done by examining the results of the discipline of exposure assessment. As different location, lifestyles and other factors likely influence the amount of contaminant that is received, a range or distribution of possible values is generated in this step. Particular care is taken to determine the exposure of the susceptible population s.
The results of these steps are combined to produce an estimate of risk. Because of the different susceptibilities and exposures, this risk will vary within a population.
An uncertainty analysis is usually included in a health risk assessment.
Dynamic risk assessment[ edit ] During an emergency response, the situation and hazards are often inherently less predictable than for planned activities non-linear.
In general, if the situation and hazards are predictable linear , standard operating procedures should deal with them adequately. In some emergencies this may also hold true, with the prepared and trained responses being adequate to manage the situation. In these situations, the operator can manage risk without outside assistance, or with the assistance of a backup team who are prepared and available to step in at short notice.
Other emergencies occur where there is no previously planned protocol, or when an outsider group is brought in to handle the situation, and they are not specifically prepared for the scenario that exists but must deal with it without undue delay.
Examples include police, fire department, disaster response and other public service rescue teams. In these cases ongoing risk assessment by the involved personnel can advise appropriate action to reduce risk. It relies on experience, training and continuing education, including effective debriefing to analyse not only what went wrong, but also what went right, and why, and to share this with other members of the team and the personnel responsible for the planning level risk assessment.
Some of these are listed here. General health[ edit ] There are many resources that provide health risk information.
Prevent injuries or illnesses, especially when done at the design or planning stage. Prioritize hazards and control measures. Meet legal requirements where applicable. What is the goal of risk assessment? The aim of the risk assessment process is to evaluate hazards, then remove that hazard or minimize the level of its risk by adding control measures, as necessary. By doing so, you have created a safer and healthier workplace. The goal is to try to answer the following questions: What can happen and under what circumstances?
What are the possible consequences? How likely are the possible consequences to occur? Is the risk controlled effectively, or is further action required? When should a risk assessment be done? There may be many reasons a risk assessment is needed, including: Before new processes or activities are introduced. Before changes are introduced to existing processes or activities, including when products, machinery, tools, equipment change or new information concerning harm becomes available.
When hazards are identified. How do you plan for a risk assessment? In general, determine: What the scope of your risk assessment will be e. The resources needed e. What type of risk analysis measures will be used e. Who are the stakeholders involved e.
What relevant laws, regulations, codes, or standards may apply in your jurisdiction, as well as organizational policies and procedures.
How is a risk assessment done? Assessments should be done by a competent person or team of individuals who have a good working knowledge of the situation being studied. Include either on the team or as sources of information, the supervisors and workers who work with the process under review as these individuals are the most familiar with the operation.
In general, to do an assessment, you should: Identify hazards. Determine the likelihood of harm, such as an injury or illness occurring, and its severity.
Consider normal operational situations as well as non-standard events such as maintenance, shutdowns, power outages, emergencies, extreme 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.
By doing so, you have created a safer and healthier workplace. Assessments should be done by a competent person or team of individuals who have a good working knowledge of the situation being studied. Include either on the team or as sources of information, the supervisors and workers who work with the process under review as these individuals are the most familiar with the operation.
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.
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.
Each hazard should be studied to determine its' level of risk. To research the hazard, you can look at:. 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. 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:. 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. 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:. 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.
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. Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.

Search all fact sheets: Type a word, a phrase, or ask a question. Risk assessment is a term used to describe the overall process or method where you: Identify hazards and risk factors that have the potential to cause harm hazard identification.
Analyze and evaluate the risk associated with that hazard risk analysis, and risk evaluation. Determine appropriate ways to eliminate the hazard, or control the risk when the hazard cannot be eliminated risk control. The CSA Standard Z "Occupational health and safety - Hazard identification and elimination and risk assessment and control" uses the following terms: They help to:Software evolution[ edit ] Studies have shown that early parts of the system development cycle such as requirements and design specifications are especially prone to error.
Check for local requirements in your jurisdiction. Further investigation identifies options such as separating noninfectious from infectious wastes, or air pollution controls on a medical incinerator. Drawing on empirical stakeholder surveys and desk research, the study analyses the various practical and regulatory approaches to risk assessment in EIA in the EU Member States. Thus, it is not unusual for there to be an iterative process between analysis, consideration of options, and follow up analysis.
They consist of three main parts: Part one — Main body: This part provides policy guidance on what it takes to conduct a successful disaster risk assessment and focuses on the three stages of the assessment process: Stage I: Preparing and scoping Stage II: Conducting risk analysis Stage III: Using the results for disaster risk management and development decisions.
Higher levels of risk may be acceptable in special circumstances, such as military or search and rescue operations when there is a chance of recovering a survivor. In general, if the situation and hazards are predictable linear , standard operating procedures should deal with them adequately.
