•Electrocution is a major cause of injury and death
in both the industrial and home environment.
•Most electrocution injuries occur at voltages
above 50 Volts AC or 100 Volts DC, however
sometimes the voltage can be much lower.
What is the cost in
$$$$$$..
• Each year, electrical accidents result in
more than $2 billion in property damage
to home and industry..
But what about the cost in human terms
Caused by 24 volt DC battery
Caused by kneeling on a
defective 110 volt ac extension
cord
Notice where watch band &
screwdriver were in contact with
skin
Notice the path in & the path out
How do you put a price tag on this?
But more important is the is the cost in lives……

Let’s talk about personal protection and the home
40,000 residential fires annually which are caused by problems
with electrical wiring systems, claiming more than 350 lives
Additionally, electric cords and plugs were involved in about
7,100 fires resulting in 120 deaths or about 32% of all
deaths associated with residential electrical system fires,
occurring each year.
Lamps and light fixtures were involved in about 8,900 fires and
60 deaths
About 3,600 people are treated for injuries associated with
extension cords.
Switches and outlets are involved in 4,700 fires and deaths
