Basic Electrical Safety

[Maritime Training Services Inc.] [ELECTRICITY: SAFETY AT SEA Hazard awareness] Electricity is an essential part of our lives. Almost all of the activities we do today involve electricity in one way or another. But by using electricity so much everyday, we also increase the risks and hazards that come with it. These risks increase significantly onboard vessels due to the unique conditions and situations you face compared to land based electrical use such as metal decks and metal construction of the ship, wet and unpredictable weather environments, and the many confined work spaces and reduced clearances on vessels. Because of these increased risks, it is important that you learn to identify and mitigate electrical hazards. Only certified personelle should be involved in the repair, test, and operation of the electrical equipment onboard. Poor training, inexperience, and failure to identify potential hazards can cause electric shock, fire, art flash, and consequently may lead to serious injury and even death. But by following the simple steps in this program, you can stay better aware of dangerous situations and even prevent them. [ELECTRICAL HAZARDS] Electric shock occurs when someone makes contact or is even too close to exposed energized electrical equipment. This exposure causes a variety of injuries and health complications that can be fatal. Art flash occurs when an electric current flows through an air gap between conductors. If conditions are appropriate, an art flash will occur, followed by a blast wave that reaches temperatures up to 35 000 degrees That is four times hotter than the surface of the sun. This type of blast usually contains molten metal shrapnel, and toxic gases. [Toxic Gases] If you or your fellow seafarers are exposed to any level of electrical shock or art flash, you must always seek medical attention. Electricity has the capability to cause serious damage. However, the risks and danger electricity poses can be mitigated, creating a safe environment onboard. All portable electric hand tools and temporary lighting systems should be plugged into ground faulted circuit interrupters when in use. Ground fault circuit interruptors also known as residential current devices, monitor electrical flow, and upon detection of any imbalances will trip, significantly lowering the risk of electric shock. When working directly on, or around electrical equipment, it is recommended you de-energize the equipment When de-energizing, you should always correctly use the 'Lock out, Tag out' system, as is required by OSHA standards. It is important to familiarize yourself with the vessels particular Lock out Tag out procedure One thing all Lock out Tag out procedures have in common is that you should never attempt to operate the circuit or remove someone else's lock in a Lock out Tag out system. It is good practice to inspect any electrical equipment and tools before use. When inspecting, you should look out for exposed wiring, damaged sockets exposure to liquids and moisture missing lightbulbs gaps in insulation corroded connections worn, or frayed electric cables Damaged equipment must be tagged and immediately fixed or removed from service. In the event of a fire caused by, or around electricity, de-energize the equipment immediately and use a dry chemical fire extinguisher suitable for electrical fires. Water and liquids have high conductivity and therefore are considered as hazards when in close proximity to electricity and electrical equipment. You should only remove liquids after the area is de-energized. If you notice a hazard and have doubts on how to handle the situation, make sure you notify your superiors or appropriate personnelle. When faced with any electrical hazard or risk, make sure you wear the corresponding non-conductive Personal Protective Equipment for the job. In the event that a fellow seafarer is being shocked, never come into direct contact with the individual [NEVER COME INTO DIRECT CONTACT] as you could also get trapped into the shock cycle First, deactivate the power source if possible, and then commence your emergency response plan. The presence of electricity in our lives will undoubtedly increase over time as we progress into the future. But by identifying potential electrical hazards, and taking the necessary precautions to deal with them we can ensure a safer working environment for you and your fellow seafarers.
