Explain first aid for electrical shock with reference to the following safety precautions: -
Answer-• TURN OFF THE POWER as quickly as possible • If unable to locate the
power switches, do not attempt to touch the victim. Touching the victim will pass the
current through anyone who touches the victim
• If electrical power cannot be removed, use a dry wooden pole, wooden broom, or dry
wooden chair to PUSH or ROLL the victim clear of the power source. Dry,
nonconducting objects made of cardboard, plastic, or wood are suitable to use to
remove the victim from the power source
• If clothing, belt, rope, or cord must be used, be careful to AVOID CONTACT WITH
THE VICTIM! Form the rescue device into a loop, and slip the loop over the foot, leg, or
arm of the victim (without touching the victim) to drag them away from the power source
• Once the victim is "free" of the power source, do not move them unless it is necessary
• Proper Steps to Take in Case of Need for First Aid—When someone needs first aid
after electrical shock, follow these steps: > Keep the victim lying down > Slightly elevate
their legs and feet > Cover the victim with a blanket to maintain body heat > Do not
move the victim unless it is necessary > Seek qualified medical aid, but try not to leave
the victim alone > If the victim needs water, give them a few sips of water at first. Then,
gradually increase water intake unless nausea is present

First Aid and CPR: - Answer-American Heart Association Guide for CPR, October 18,
2010:
• Call 911 or ask someone else to do so
• Try to get the person to respond; if he doesn't, roll the person on his or her back
• Start chest compressions. Place the heel of your hand on the center of the victim's
chest. Put your other hand on top of the first with your fingers interlaced
• Press down so you compress the chest at least 2 inches in adults and children and 1.5
inches in infants. ''One hundred times a minute or even a little faster is optimal," (That's
about the same rhythm as the beat of the Bee Gee's song "Stayin' Alive.")
• If you're been trained in CPR, you can now open the airway with a head tilt and chin lift
• Pinch closed the nose of the victim. Take a normal breath, cover the victim's mouth
with yours to create an airtight seal, and then give two, one-second breaths as you
watch for the chest to rise
