Electrical Safety Testing Quiz

Working with electrical devices with wet hands can increase the risk of electric shock or electrocution. Water is a conductor of electricity, and when it comes into contact with live electrical components, it can create a path for the electric current to flow through the body, causing harm. Therefore, it is important to always ensure that hands are dry before handling electrical devices to minimize the risk of accidents.

Safety-related work practices involve the use of ground fault circuit interrupters to prevent electric shock and fire hazards. Verifying power is off before doing repairs ensures that workers are not exposed to live electricity, reducing the risk of accidents. Keeping a proper distance from overhead power lines is crucial to prevent electrocution and other hazards. Therefore, all of the mentioned practices are important for maintaining safety in the workplace.

Static electric shock can indeed cause injury. When a person experiences a static electric shock, it is usually due to a build-up of static electricity on their body, which is then discharged when they come into contact with a conductor. The shock can range from a mild tingling sensation to a more severe jolt, depending on the intensity of the discharge. In some cases, this shock can lead to injuries such as burns, muscle contractions, and even falls or accidents. Therefore, it is important to be cautious and take necessary precautions to avoid static electric shocks.

This statement is false because electricity can be extremely dangerous. It has the potential to cause severe injuries, electrocution, and even death if not handled properly. It can also lead to fires if there is a malfunction or short circuit in electrical equipment. Therefore, it is important to take necessary precautions and be cautious while dealing with electricity to avoid any accidents or hazards.

Non-conductive head protection is necessary in situations where there is a risk of head injury from electric shock. Since electricity can easily pass through conductive materials, wearing non-conductive head protection helps to prevent the electric shock from reaching the head and causing injury. Therefore, it is important to wear non-conductive head protection when there is a danger of head injury from electric shock.

The correct answer is "All of the above" because when dealing with electricity, it is important to have the necessary equipment to ensure safety. Wearing rubber gloves provides better protection against electric shock. Additionally, having someone with you can be helpful in case of an emergency or if assistance is needed. Therefore, all of these options are necessary when dealing with electricity to minimize the risk of accidents or injuries.

Conductive articles of jewelry and clothing should not be worn around exposed energized parts because they can increase the risk of electrical shock or injury. Conductive materials can conduct electricity and create a path for electrical current to flow through the body, which can be extremely dangerous. It is important to avoid wearing conductive articles in situations where there is a risk of coming into contact with exposed energized parts to ensure personal safety.

It is important to never touch a naked wire because it can cause electric shock or electrocution. Naked wires are exposed and not insulated, which means that they carry live electrical current and can be extremely dangerous to touch. Touching a naked wire can result in severe injuries or even death. Therefore, it is crucial to exercise caution and avoid any contact with naked wires.

The correct answer is A and C. Altering a 3-prong plug to fit a 2-prong outlet is considered an unsafe act because it can lead to electrical hazards and potential electrocution. Working too close to overhead power lines is also classified as an unsafe act as it can result in electric shock or even fatal injuries. Using a GFCI (Ground Fault Circuit Interrupter) is not considered an unsafe act, as it is a safety device designed to protect against electrical shocks.

Electric cords are used to provide electrical power to equipment, not for raising or lowering the equipment. The correct method for raising or lowering equipment would typically involve using mechanical mechanisms such as pulleys, levers, or hydraulic systems. Hence, the statement is false.

Concrete is a conductive material due to the presence of water and minerals, allowing electrical current to flow through it. The water acts as an electrolyte, facilitating the movement of charged particles. This property is often utilized in construction, where electrical wiring is embedded within concrete structures. Therefore, it is correct to say that electrical current can flow through concrete.

University departments may decide whether to have alterations done by Physical Plant personnel or to do it themselves. This statement is false because university departments do not have the authority or capability to make decisions regarding alterations. It is the responsibility of the Physical Plant personnel to make decisions and carry out alterations according to the needs and requirements of the departments.

The statement suggests that it is necessary to always wear a jacket before working with electricity. However, this is not true. While it is important to take safety precautions when working with electricity, such as wearing protective gear, a jacket specifically may not be required in all situations. Other safety measures, such as insulated gloves and safety goggles, may be more appropriate depending on the specific task at hand.

The correct answer is "Use of proper extension cord to power an appliance for a short time". This is because using a proper extension cord to power an appliance for a short time does not require specialized electrical knowledge or skills, and can be done by a person who is not an electrician. The other options mentioned in the question involve tasks that should ideally be performed by a trained electrician to ensure safety and compliance with electrical regulations.

Extension cords must have UL Listing, which ensures that the product has been tested and meets safety standards. They must also have three prongs, which includes a grounding pin to prevent electrical shocks. The presence of a fuse is not a requirement for extension cords. Therefore, the correct answer is "A and B" because extension cords must have UL Listing and three prongs.
