If they lose consciousness and aren't breathing, you should begin cardiopulmonary resuscitation (CPR) with chest compressions.

To guard against the risk of vehicle accidents, Totalkare advises that workshops where staff are manoeuvring vehicles around or over an inspection pit should have: The difference between the balanced twisted windings CM choke and conventional balanced two winding CM choke is that the windings interact in the center of the core open window. When it is conducting CM current, the balanced twisted winding CM inductor can provide identical CM inductance as the conventional CM inductor. When it is conducting DM current, the equivalent current loops will generate inversed direction magnetic fields in space so that they tend to cancel each other. Give up to 5 sharp blows between their shoulder blades with the heel of your hand. The heel is between the palm of your hand and your wrist. A designated, trained marshal – to instruct and guide the driver, and watch for other vehicles or workers nearby.

The full guidance, available via www.is.gd/izawej, covers both road vehicles and those used off-road and in mines and quarries, with a payload of up to 250 US tons (approximately 227t). Support them, lowering them gently to the ground and treat them as someone who is unresponsive and not breathing. Abdominal thrusts can cause serious injuries. A health professional such as your GP or a doctor in A&E should always examine someone after they have received abdominal thrusts. Further information A current is passed through an inductor, and a probe measures the near field emission. A signal generator, serving as a voltage source, is connected to an amplifier. The output of the amplifier is then connected to the inductor under measurement. To monitor and control the current flowing through the inductor, a current clamp meter is clamped around the conducting wire. An oscilloscope connected to the current clamp to measures the current waveform. A probe measures the flux in the air. A spectrum analyzer connected to the probe collects data.Where choking is severe, the person won't be able to speak, cry, cough or breathe. Without help, they'll eventually become unconscious. Some car audio hobbyists use choke coils with car audio systems (specifically in the wiring for a subwoofer, to remove high frequencies from the amplified signal). This is sometimes called the Heimlich manoeuvre or abdominal thrust. Don’t do this on a child under a year old.
