A young boy was electrocuted in the late 1880s when he inadvertently touched an unlabeled, energised telegraph cable. The incident prompted Harold Pitney Brown, an inventor, to make an impassioned appeal in a New York Post editorial to restrict telegraph transmissions to 300 Volts, which he considered a safer standard.Learn more by visiting Forklift Trainer Training in Newark
Harold may have reasoned that restricting electrical transmissions to 300 volts or less would ensure immediate electrical protection. With the advantage of over 120 years of hindsight, we now see it very differently. Harold did, however, come across two crucial ideas. The term “300 Volts” refers to a scientific discussion of electrical energy laws (Ohm’s Rule, for example) that helps to explain how electrical energy can kill or maim. The word “security,” on the other hand, denotes a working understanding of the fundamental concepts of protection. Our task is to apply our technical knowledge of electricity to safety standards to ensure that electrical safety is both realistic and reliable. The more we understand these principles, the more likely we are to change the current situation. The Risk Management Hierarchy (RCH) does a brilliant job of integrating these two essential ideas.
Hierarchy of Risk Management
The Risk Control Hierarchy (RCH), which can be found in Appendix G of the ANSI Z10 Standard, is the beating heart of safety. The RCH assists us in prioritising safety measures in order of least to most successful. Would it be better to ride a motorcycle without a helmet or without a motorcycle altogether? Obviously, selling the motorcycle reduces the risk of an accident, whereas wearing a helmet reduces the risk of a head injury in the event of an accident. The RCH works by assisting us in ranking risk reduction initiatives from most to least successful, as shown below:
1 Taking the risk out of the equation.
2 Use a lower-risk option.
3 Risk-based engineering.
4 Being mindful of all risks.
5 Manage and control risk-taking actions.
6 Keep staff safe when they are at risk.
It’s worth noting that while each of the steps mentioned above is significant, they’re not all equally successful in protecting employees. The most effective way to keep staff safe is to remove a risk, while using Personal Protective Equipment (PPE) to shield them from a risk is the least effective. PPE has come a long way in terms of construction, but its primary goal is to keep staff alive, not to keep them completely safe.
Danger and Safety
Risk is a two-pronged concept that refers to being exposed to a threat. There is the risk of exposure as well as the seriousness of the possible injury. A 120V outlet, for example, poses a greater danger than a 13.8KV switchgear line-up since it is used by more people. Since risk is defined as the exposure to hazards, protection is defined as the reduction and management of risk. An electrical engineer is normally in charge of overseeing an electrical safety programme since he or she is acquainted with electricity. We will never be able to fully eradicate danger in our modern world, but we are very good at finding new ways to reduce it.
