Identifying hazards and assessing the level of risk associated with those hazards is the most important activity you perform every day, at work and away from work. Effective health and safety management is based on a universal understanding of risks and how to control them through good planning.

Willem Maes High Voltage Safety

A Risk Assessment (RA) is a process that: identifies hazards evaluates the risk of harm from those hazards implements measures to eliminate or control those hazards prioritizes occupations that require Job Hazard Analysis

Willem Maes High Voltage Safety

A Job Hazard Analysis (JHA) is a process that:

• ffers a step-by step approach to recognize, assess and

control hazards and monitor the ongoing effectiveness of controls systematically evaluates certain jobs, tasks or processes helps to eliminate or reduce risks or hazards in order to protect workers from injury or illness

Basics of Risk Management

For each serious accident, there are 10 minor accidents and as many as 600 near-misses which do not include individual or material damages. The ISM code gives the freedom to individual shipowners to develop there own Safety Management System (SMS). Risk management procedures can be a part of the SMS of your shipowner.

Risk Handling Process

Nowadays the role of riskmanagement has increased in the companies. It is beneficial to understand the basics of risk management and the process behind it. Risk should be addressed in terms of the following three activities: Risk assessment Risk management Risk communication

Get input from experts and share results with decision makers when appropriate.

Risk classification process example:

Identify the hazards and potential accidents As an example: a generator without regular maintenance. A possible accident can be: loose connections ⇒ heating ⇒ explosion ⇒ fire.

Willem Maes High Voltage Safety

Define the frequency or the likelihood that an accident might happen, how often the hazard might lead to an accident: Rare (1) Unlikely (2) Possible (3) Likely (4) Probable (5) In the case of our generator without regular maintenance the probability of a loose connection is high. It may take time, but it is possible due to engine vibrations. So we give it a score of (3)

Willem Maes High Voltage Safety

Define the severity and consequences, what kind of impact the hazard and potential accident would have? Negligible (1) Minor (2) Significant (3) Serious (4) Life threatening (5) In case of our generator without regular maintenance the consequences of a loose connection could be just stopping of the generator, or more serious explosion and fire. Consequence: Significant or serious. So we give it a score of (4)

Risk Score Action(s) to be taken 1-6 Low Monitor and manage changes in the situation. Be aware of changes in the situation, take additional precautions if possible 7-12 Medium Review tasks and try to redefine the tasks to lower the risk to work As Low As Reasonably Practical (ALARP) 13-25 High Do not start the job before risks have been reduced to a level below 13.

Willem Maes High Voltage Safety

Risk Score Action(s) to be taken 1-6 Low Scope of corrective actions can be decided based on cost-effectiveness 7-12 Medium situation no longer conforms to legislation 13-25 High Work must be stopped immediately or may not be started under any circumstances

Give the risks priority which need the most urgent attention or which need attention over a longer period of time. If the risk priority level needs to be reduced the following action should be taken. Remove the hazard Restrict the effects of the hazard Isolate the hazard Remove the employee Moderate the consequences of risk

Recruit a suitable employee Inform the employees of danger Train the employee to avoid the danger Eliminate the hazard etc. It is good to remember that the final goal for risk management is to achieve the vision of zero accidents.
