Conducting a thorough risk assessment is crucial for a safer workplace. The process involves identifying potential hazards and evaluating their likelihood and potential impact.
A risk assessment should consider all aspects of a workplace, including equipment, materials, and employee behavior. This includes reviewing existing safety policies and procedures.
Regular risk assessments can help prevent workplace injuries and illnesses. A well-structured risk assessment process can also reduce the likelihood of costly accidents and downtime.
By following a systematic approach to risk assessment, businesses can create a safer and more productive work environment.
Be Prepared
To be prepared for a risk assessment, you need to define the scope of your assessment. This includes outlining the processes, activities, functions, and physical locations that will be included in the assessment.
Having a clear scope will help you determine the time and resources needed to complete the assessment. It's essential to outline what is included and what isn't to accurately plan and budget.
You'll also need to identify the necessary resources, including time, personnel, and financial resources. This will help you allocate the necessary funds and personnel to complete the assessment.
Stakeholders are also an important consideration. You'll need to identify who is involved in the risk assessment, including senior leaders, an assessment team, and subject matter experts.
Laws and regulations will also impact your risk assessment. Familiarize yourself with the relevant laws and regulations, such as OSHA standards, to ensure your organization is compliant.
Here are the key elements to consider when planning for a risk assessment:
Identify Hazards
Identifying hazards is the first step in creating a risk assessment. It involves determining what hazards your employees and business face.
To identify hazards, survey your workplace and look at what could reasonably be expected to cause harm. This includes natural disasters, biological hazards, workplace accidents, intentional acts, technological hazards, chemical hazards, mental hazards, and interruptions in the supply chain.
Check the manufacturer's or suppliers' instructions or data sheets for any obvious hazards. Review previous accident and near-miss reports to determine what hazards have impacted your company in the past.
Some common workplace hazards include slips and trips, transportation accidents, structural failure, mechanical breakdowns, pandemic diseases, and excess workload. Don't forget to consider remote workers and non-routine activities such as repair and maintenance.
Here are some examples of hazards to consider:
- Natural disasters (flooding, tornadoes, hurricanes, earthquakes, fire, etc.)
- Biological hazards (pandemic diseases, foodborne illnesses, etc.)
- Workplace accidents (slips and trips, transportation accidents, structural failure, mechanical breakdowns, etc.)
- Intentional acts (labor strikes, demonstrations, bomb threats, robbery, arson, etc.)
- Technological hazards (lost Internet connection, power outage, etc.)
- Chemical hazards (asbestos, cleaning fluids, etc.)
- Mental hazards (excess workload, bullying, etc.)
- Interruptions in the supply chain
By identifying these hazards, you can take steps to mitigate the risks and create a safer work environment for everyone.
Risk Assessment Process
The risk assessment process is a crucial step in identifying and mitigating potential risks. It's essential to approach this process in a structured way to ensure that all relevant factors are considered.
To efficiently perform risk assessments, you can follow a 5-step process.
The first step is to identify potential risks, which can be done by gathering information from various sources, including historical data, industry trends, and expert opinions.
For another approach, see: What Are the Risks of Getting Braces?
Risk assessments can be performed in 5 steps, making it a manageable task for organizations of all sizes.
The second step is to assess the likelihood and potential impact of each identified risk. This helps prioritize risks and allocate resources accordingly.
Breaking down the risk assessment process into smaller steps makes it easier to tackle.
The third step is to evaluate existing controls and measures in place to mitigate or manage identified risks. This step helps identify gaps in current risk management strategies.
Risk assessments can be performed in a variety of industries, from manufacturing to finance.
The fourth step is to develop and implement new controls or measures to address identified gaps and mitigate risks. This step requires collaboration among stakeholders, including management, employees, and external experts.
Risk assessments should be performed regularly to ensure that risks are continuously monitored and addressed.
The fifth step is to review and update the risk assessment process to ensure it remains effective and relevant. This step involves revisiting the risk assessment framework and making adjustments as needed.

Risk Assessment Methods
Risk assessment methods can vary depending on the situation and the level of detail required. In simple situations, a discussion or brainstorming session based on knowledge and experience can be enough.
For more complex situations, a team of knowledgeable personnel familiar with the work and risk assessment methodologies is usually necessary. The legislation may specify how the risk assessment needs to be done, including what personnel need to be involved.
There are various qualitative methods that can be used, including the basic qualitative method, which combines severity and probability parameters to produce a level of risk. The basic qualitative method uses a risk matrix to evaluate risk based on the inherent characteristics of the hazard without assigning a numerical value.
The risk matrix chart can be used to determine the priority for addressing hazards based on their risk rating. The risk matrix chart has two primary dimensions: probability and impact, each represented on one axis of the chart.
Methods to Use
Risk assessment methods are numerous, and the right one for your organization will depend on various factors, including the experience level of your team, the scope of the project, and the level of detail required to understand the risks.
There's no one-size-fits-all approach to risk assessment, and the method used will often depend on the situation. For simple or less complex situations, a discussion or brainstorming session based on knowledge and experience can be sufficient. However, for more complex situations, a team of knowledgeable personnel familiar with the work and risk assessment methodologies is usually necessary.
A risk matrix is a common tool used to measure the level of risk by considering the consequence/ severity and likelihood of injury to a worker after being exposed to a hazard. Two key questions to ask when using a risk matrix are: "Consequences: How bad would the most severe injury be if exposed to the hazard?" and "Likelihood: How likely is the person to be injured if exposed to the hazard?"
You can use a risk matrix like the 3×3, 4×4, or 5×5 matrix to plot risks on a chart, which allows you to determine priority and resource allocation. For example, the 3×3 risk matrix has very likely and highly unlikely categories for likelihood, and fatality and medium consequences categories for consequences.
To prioritize risks, create a risk assessment chart that plots risks based on their probability and impact. This will help you focus your time and effort on preventing the most important hazards. The chart is based on the principle that a risk has two primary dimensions: probability and impact.
To create a risk assessment chart, you'll need to determine the probability and impact of each risk. You can use a risk matrix like the one shown in Example 2 to help you plot the risks on the chart. The chart will allow you to determine the priority and resource allocation for each risk.
There are several types of qualitative risk assessments, including hazard and operability (HAZOP) analysis, bowtie analysis, and other similar risk matrices. These methods evaluate risk based on the inherent characteristics of the hazard without assigning a numerical value.
In semi-quantitative methods, you assign numerical values or scores to various qualitative risk factors and then use these scores to rank or prioritize risk. For example, you can use a semi-quantitative risk matrix like the one shown in Table 3 to assign scores for severity and probability.

Once you've established the priorities, your organization can decide on ways to control each specific hazard. Hazard control methods are often grouped into the following categories: elimination, substitution, engineering controls, administrative controls, and personal protective equipment.
Here are some examples of hazard control methods:
- Elimination: Removing the hazard from the workplace
- Substitution: Replacing the hazard with a safer alternative
- Engineering controls: Using physical barriers or equipment to control the hazard
- Administrative controls: Changing policies or procedures to control the hazard
- Personal protective equipment: Using protective gear such as gloves or masks to control the hazard

Risk Assessment Steps
To perform a risk assessment, you need to follow a series of steps. The first step is to identify the hazards, which can include natural disasters, biological hazards, workplace accidents, and intentional acts.
A field-level risk assessment can be used in industries and workplaces where workers are exposed to dynamic and changing work environments. This type of assessment can use qualitative or semi-quantitative methods for assessing risk.
The risk assessment process involves several steps, including risk characterization, which involves combining information from toxicity and exposure to calculate estimates of risk. This process includes all the assumptions and scientific information used to estimate risk, the uncertainty associated with the assessment, and any other information that may be useful to decision makers.
Here's a table that summarizes the field-level risk assessment process:
To complete a field-level risk assessment, you should write down each step of the task and identify the hazards, then assess the risk based on the likelihood and severity of harm.
Step 1: Hazard ID
Hazard identification is the first step in any risk assessment. It involves looking for potential hazards in the workplace or environment.
To identify hazards, you should survey the area and look for things that could reasonably be expected to cause harm. This includes common workplace hazards, such as natural disasters, biological hazards, and workplace accidents.
Some sources to consider when identifying hazards include accident and near-miss reports, manufacturer's or supplier's instructions, and data sheets. These sources can provide valuable information about potential hazards and help you identify areas that need attention.
Here are some examples of hazards to consider:
- Natural disasters (flooding, tornadoes, hurricanes, earthquakes, fire, etc.)
- Biological hazards (pandemic diseases, foodborne illnesses, etc.)
- Workplace accidents (slips and trips, transportation accidents, structural failure, mechanical breakdowns, etc.)
- Intentional acts (labor strikes, demonstrations, bomb threats, robbery, arson, etc.)
- Technological hazards (lost Internet connection, power outage, etc.)
- Chemical hazards (asbestos, cleaning fluids, etc.)
- Mental hazards (excess workload, bullying, etc.)
- Interruptions in the supply chain
By identifying potential hazards, you can take steps to mitigate or eliminate them, reducing the risk of harm to people and the environment.
Step 2: Exposure
Exposure assessment is a crucial step in risk assessment. It involves evaluating how likely it is that a hazard will cause harm to workers.
IDEM establishes long-term monitoring if necessary and studies chemical levels. This may require years of sampling or a simple surface wipe, depending on the contaminant.
Exposure assessment considers various factors, including inhalation, absorption, and ingestion, as well as the daily lives and habits of people living in the area. This helps determine how they are exposed to hazardous chemicals.
IDEM may include meteorological data in its exposure analysis to get a more accurate picture. This ensures that the data is quality-assured and verified.
To assess exposure, you can look at various sources, including product information, past experience, legislated requirements, and industry codes of practice. You can also consult health and safety material, such as safety data sheets, research studies, and manufacturer information.
Here are some key factors to consider when assessing exposure:
- Inhalation, absorption, and ingestion routes
- Daily lives and habits of people in the area
- Meteorological data
- Work environment, including layout, condition, and weather
- Procedures for performing a task
- Range of foreseeable conditions
- Interaction, capability, skill, and experience of workers
- Physical, psychological, or cognitive abilities and characteristics of workers
- Individual worker factors, such as age, height, disabilities, allergies, sensitivities, and pregnant or breastfeeding workers
- Number of people that could be impacted
- Working alone or in a remote area
By considering these factors, you can get a better understanding of how likely it is that a hazard will cause harm to workers.
Step 3: Dose-Response
Dose-response assessment is a critical step in evaluating the potential risks associated with exposure to chemicals. IDEM uses dose-response [ZIP] to assess the risk from exposure to chemicals.
IDEM scientists conduct research, including animal studies, to develop dose-response factors. These factors are then applied to risk assessment studies to estimate the potential risks.
The dose-response factor used will depend on the specific study parameters. Scientists choose the factor that best fits the study's parameters, ensuring an accurate assessment of potential risks.
IDEM's goal is to provide a comprehensive understanding of the potential risks associated with chemical exposure. By using dose-response factors, IDEM can estimate the increased risk for a study area based on air toxics monitoring data.
IDEM shares its complete studies with the public, providing transparency and helping citizens understand the variables that affect the accuracy of the study.
