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: offers 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 Willem Maes High Voltage Safety

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.

Basics of Risk Management Associated Terminologies Risk: combination of probability and severity Hazard: potential to form or contribute to, a harmful event Risk analysis: systematic identification of workplace hazards and their severity Risk assessment: evaluating whether risks are acceptable Willem Maes High Voltage Safety

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 Willem Maes High Voltage Safety

Risk communication Get input from experts and share results with decision makers when appropriate. Willem Maes High Voltage Safety
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
