If companies want to make the right decisions in risk management, ALARP is the key. This principle is mainly crucial when considering safety and money. With enough budget, the practice lowers potential hazards to a safe level. This method is not optional since the law strictly regulates it.
Many people mistake it as simply about making a low effort. It requires good judgment from experienced experts to find a balance between finding the best solution with the lowest cost and effort. This article provides a deeper explanation of how it works. The discussion also addresses what the rule means and what it doesn’t.
What does ALARP mean?
ALARP stands for As Low As Reasonably Practicable. It is a safety principle to reduce the risk level to the lowest with minimal time, money, and effort. Workplaces, factories, or plants must apply these principles to ensure that they are safe and healthy. HSE managers, engineers, and regulators are most likely responsible for knowing how to use and quality control this practice.
To put it simply, there are three levels of risk: intolerable, tolerable, and acceptable. The highest one (intolerable) must be dealt with. These are unacceptable, and companies must prevent the danger, no matter the time or cost. On the other hand, tolerable risk means the hazard is moderate, and reducing it to a safe level is enough. Lastly, this is where ALARP comes in. The last category, acceptable risk, means the problem is already secure and doesn't need any action.
Imagine you are an engineer creating a safe pedestrian street. To lower the risk of accidents, you build traffic lights and signs, which do not require much time and money. You could do extra by building big flyovers or underground tunnels. However, it may be unnecessary and more expensive, but it'll only optimise the safety slightly. ALARP means you do enough to make it safe in a practical way, without applying extra measures that only improve a little bit more.
The principles of ALARP
After all, we cannot completely remove all dangers. It takes money and time, and safety workers must know how to use these wisely. ALARP does not mean they should be cheap with money. The idea is to remind the business that they can’t let the danger be small compared to the effort, money, and time. After all, health and security save businesses from bigger costs caused by unprevented accidents.
Workers must understand what “Reasonably Practicable” means and what it doesn’t. Doing what you can to lower dangers is reasonably practicable, but doing everything possible, no matter the cost, is not. Evaluating the risks carefully is reasonably practicable, but ignoring them to save money is not. These are other principles you should know:
- Risk Reduction: Companies should always aim to lower threats to people’s well-being as much as they can. ALARP might sound like it’s about saving money, but it still focuses on safety first. It doesn’t make sense to reduce the budget now if the company ends up paying more later because of accidents.
- Balancing Cost and Benefit: The general idea of this effort is to find a balance. Its main rule is to review the value of safety measurement and choose methods that are worth it. In other words, it’s about reducing potential problems in a realistic way. As safety workers, you must know when spending more doesn’t really lead to better outcomes.
- Continuous Review: Companies should check on ALARP frequently. They can use it to assess its performance and search for other ways to improve it. If there are more efficient ways to reduce risks, you can suggest them. Checking the process also enables the team to take immediate actions when needed. Follow the most updated rules and safety standards to prevent further dangers from happening.
Is ALARP regulated in UK Law?
In the UK, several main safety regulations include ALARP, although the government does not directly state it as a law. Some rules related to these welfare principles are: Health and Safety at Work etc. Act 1974 (HSWA), Control of Major Accident Hazards (COMAH) Regulations 2015, and Offshore Installations (Safety Case) Regulations 2005.
Those laws ensure that companies guarantee the health, welfare, and safety of their employees. It also includes a commitment to prevent harm to the environment. Experts can find the guide to the hazard controls in the rules. It informs all the framework and standards that the businesses must comply with. Furthermore, companies across industries have to follow these laws, especially those involved in activities that involve risks.
How to determine ALARP
Determining a strategy to implement ALARP involves a step-by-step process. During each step, every decision has to be documented. This is crucial to make sure everyone involved is on the same page and to make it easier for evaluation. The method starts with identifying the hazard for further assessment.
The overall process consists of the roles of stakeholders and experts. From engineers to front-line workers, consultants to assessors. Each person has different tasks, but most engage in every step of the process. The decision makers, such as managers and business owners, are the ones who focus more on cost consultation. Below are the main steps to decide and apply ALARP, you should know:
Hazard identification
First of all, some professionals will identify potential hazards in all parts of the plants. Health & safety officers, engineers, and front-line workers are most likely in charge of this process. The goal is to find things that could cause accidents, what is happening there, and what could be done. Typically, they will inspect machinery, chemicals, or job parts that require employees to work at height.
Risks assessment
The next part of the ALARP application is risk assessment. Companies need expertise from assessors, the safety team, and technicians to do this. This stage aims to evaluate the likelihood of danger and its severity. After that, they decide which issues the team will prioritise. To do this, the experts use a risk matrix to map the different problems.
Evaluation of risks
In this phase of evaluation, engineers, stakeholders, and the safety team discuss the next steps. The assessment results help them make a list of possible ways to reduce the hazard. They will then consider the cost, time, and value of each option. Stakeholders and experts finally come to a conclusion on whether the hazards are within the ALARP region or need more research.
Risk reduction
When they decide that they must apply this system, operational teams and contractors put the protection measures into practice. In each step, they must document everything, mainly the justification for the chosen method. The final result of ALARP can be different depending on the situation. For example, a company might build new infrastructure or provide safety training and certification to the team.
Monitoring and review
Supervisors, internal auditors, and the compliance team review and monitor the ALARP standard. Their job is to ensure hazards are under control and everything is working. It is also crucial to identify quickly if the team needs to change or update any devices. You don’t want new problems caused by the safety measures themselves. Thus, regular review and monitoring are essential.
Learn real-world cases of ALARP
ALARP is the principle that a risk should be lower in a practical and realistic way. The key is not about saving money, but about deciding the ways that are worth the cost. This approach is vital not only for the HSE team but also for engineers, front-line workers, and stakeholders. However, remember that this guideline only applies to tolerable risks.
