Q4 What are the key basics of high voltageelectrical safety? A4 Info Sage, Professional Maven 5h High voltageelectrical safety is of utmost importance to prevent injuries and hazardsassociated with electricity. Understanding the basics of high voltageelectrical safety can help individuals eliminate or control potential risks.Here are the key principles and guidelines to consider: 1. Electrical Shock: Electricalshock occurs when current passes through the body, and it can be fatal or causeserious injuries. Avoid touchingexposed wires of energized circuits or any metal part that has becomeenergized. Always assume thatelectrical circuits are energized unless you have verified and ensured they arede-energized. The severity of injury depends on factors such asthe amount of current, its path through the body, the duration of exposure, andthe current's frequency. 2. Fire/Explosion: Excessive resistance in electrical systems can generateheat, leading to fires. Common causes include overcurrent,faulty outlets, poor wiring connections, and damaged wiring. Electrical sparksor short circuits can ignite flammable gases or combustible dust mixtures,causing explosions. 3. Electrical Safety Basics: Avoid working withexposed conductors carrying 50 volts or more unless you are a qualifiedprofessional. Ensure that electrical equipment is properly connected,grounded, and in good working order. Extensioncords should only be used temporarily and not as permanent wiring. Remove themafter use. Use surgesuppressors with built-in circuit breakers for long-term use. Ensure they haveappropriate cord lengths. Highamperage equipment should be plugged directly into permanent wall receptacles. Only qualified andauthorized individuals should access, use, or alter any building's electricalservice, including circuit breaker panels. Wet environmentsincrease the risk of electrical shock. Use caution and appropriate safetymeasures. My note-Keep the switches of electric water heater out side bathroom. Provide a rubbermat below the switch. Provide arubber mat near washing machine. Ensure clothes are put /taken out after washing machine switchis OFF. Any insulationproblem in water heater will lead as leaky current and appear in the washingmachine metallic parts initially. 4. Grounding: Proper grounding is crucial to prevent electricalhazards. It provides an alternate path for electricityto follow, ensuring it doesn't flow through a person. Equipment withgrounding prongs should always be plugged into a grounded extension cord. Neverremove the grounding plug. 5. Wet Locations: When using electricity in wet or damp locations, such asoutdoor areas, use Ground Fault Circuit Interrupters (GFCIs).GFCIs protect against electrical shocks by creating a ground fault or leak inthe current. 6. Lockout/Tagout: When performingservicing or maintenance tasks involving electricity or electrical equipment,follow lockout/tag outprocedures to prevent unexpected equipment startup. 7. High Voltage Electrical Safety: Working on high voltage systems (greater than 600 volts)should be performed using de-energized electrical safety work practiceswhenever possible. Only qualifiedelectrical workers should handle power systems greater than 600 volts. Use permits, appropriate tools, Personal ProtectiveEquipment (PPE), and safety observers for energized electrical work. Understand clearance requirements,special hazards, procedures for extracting personnel from energized circuits,and workspace guarding. Different regulations and standards apply, suchas NFPA 70E, 29 CFR 1910 Subpart S, ANSI C2, and others. Familiarize yourselfwith relevant regulations and follow them diligently. Remember,electrical safety is crucial, and when in doubt, consult a qualifiedprofessional or electrician to ensure proper precautions are taken to preventaccidents and injuries. Q5 How many flight attendants areallowed on a plane? A5 Vishnu Ravi, Aviation Enthusiast |Content Creator Jun 7 The number offlight attendants aboard an aircraft is determined by various factors, such asthe duration of the flight, the passenger count, and the airline's regulations.The following guidelines outline the required staffing levels: According tofederal regulations enforced by the FAA (Federal Aviation Administration), there must be at least oneflight attendant for every 50 passengers on an airplane. For airplanescarrying more than 19 but fewer than 51 passengers, a single flight attendantis mandatory. In the case of airplanes carrying more than 50 but lessthan 101 passengers, a minimum of two flight attendants is required. For airplanesaccommodating more than 100 passengers, the regulation stipulates two flightattendants as a base requirement, with an additional flight attendant needed for each unit (or fractionof a unit) of 50 passengers above 100. Furthermore,airplanes with a passenger capacity ranging from 101 to 150 are legally obligedto have at least three flight attendants present on board. It is important tonote that these figures represent the minimum standards established byregulatory authorities. Airlines have the prerogative to exceed theserequirements and assign more flight attendants if they so choose. In the United States, on average, short-haul aircrafttypically employ a crew of 3 to 4 flight attendants.Medium-haul aircraft tend to have 5 to 6 flight attendants, while larger,long-haul planes typically feature approximately 8 to 12 flight attendants. It is worth mentioning that while these figures serve asminimum guidelines, airlines retain the discretionto augment the number of flight attendants onboard, surpassing the mandatedminimums if they deem it necessary.
