Aid - Electric Shock
An electric shock occurs when a person comes into
contact with an electrical energy source. Electrical energy
flows through a portion of the body causing a shock. Exposure
to electrical energy may result in no injury at all or may
result in devastating damage or death. Burns are the most
common injury from electric shock. Electric shocks can result
- Slight shocking sensations
- Muscle spasms
- Interrupted breathing
- Irregular heart beats
- Third degree burns (at the spots where
the electricity enters and exits the body)
The Fatal Current:
Electrocution occurs when a small, specific amount of electrical
current flows through the heart for 1 to 3 seconds. 0.006-0.2
Amps (that's 6-200mA milliamps) of current flowing through
the heart disrupts the normal coordination of heart muscles.
These muscles loose their vital rhythm and begin to fibrilate.
Death soon follows. To provide an example of how small an
amount of current it takes to kill; a 15 Watt night light
draws about 125mA
People can be electrocuted when they touch high-tension
wires that fall during a storm or are struck by lightning.
A bolt of lightning carries as many as 30 million volts, more
than 250,000 times the voltage of ordinary household current.
July is the most dangerous month for lightning.
Take care when rescuing
someone who has been electrocuted so you do not become a victim
as well. Isolate the source of Danger.
Be alert for hazards! It is urgent that the casualty be disconnected
from the electrical source, either by:
- turning off the power supply and disconnecting
any plugs from the outlet, and isolating the electricity
supply at the main powerboard if possible; or
- removing the casualty from the electrical
source by pushing or pulling them with non conducting materials,
eg, wooden stick or board, rope, or blanket.
- call 999 for an ambulance
- if in respiratory arrest - commence Expired
- if in cardiac arrest - commence CPR
- cool and cover burns with non-adherent
Neighbourhood First Responder Scheme
Helping to save lives in
The objective of the Hilmarton Neighbourhood First Responder
Scheme is to provide local support to the Great Western Ambulance
Service NHS Trust and local community by responding to specific
emergency calls in the Hilmarton and Lyneham area. The Scheme
consists of volunteers trained by Wiltshire St. John Ambulance
and the Great Western Ambulance Service NHS Trust. We provide
vital life saving treatment and first aid prior to the arrival
of an emergency ambulance.
The Schemes success is based on local people giving some
time to be trained and to be on-call to support their the
local community. We are particularly interested in recruiting
suitable volunteers in the Lyneham area who would be willing
to provide on-call support during the working day and at weekends.
No previous first aid experience is required as full training
is provided free of charge by Wiltshire St. John Ambulance
and the Great Western Ambulance Service NHS Trust.
If you think you've got what it takes to become a Neighbourhood
First Responder within the Hilmarton Scheme, why not give
the Scheme co-ordinator, Simon Barnfather, a call on 07970
