SIGNALS CROSSED -A LIFE LOST
A worker was driving a
concrete buggy onto a hoist platform. Or so he thought!
When he arrived where the platform should have been,
it wasn't there. The buggy went over the edge. The man fell forward off
the buggy and hit the ground 18' below. Why did this fatal accident occur? The
hoist engineer thought that a signal had been given and lowered the platform
just before the driver got there.
STATION SIGNALMAN PROPERLY
How can an accident
like this be avoided? The answer is simple: a signal man should be stationed at
the elevation where materials are to be loaded or unloaded. The hoist operator
should move the platform only after receiving a sign from the signal man.
SIGNALMAN MUST BE QUALIFIED
The signalman must be a
fully qualified, responsible individual with no other duties. This individual
must be the only one the operator of equipment looks to for signals. The signals
used must be understood by them both. The signalman and the operator must be
alert every minute, so that no signal will be badly timed, incorrectly given, or
NO ONE ELSE SHOULD SIGNAL - EXCEPT IN EMERGENCY
Others nearby should
not wave their hands or arms in an attempt to signal the operator. There's just
one exception to this rule: "Any-one can give a signal in an
emergency". The operator must stop immediately upon receiving such a
signal, no matter who gives it. If for any reason the operator can't see the
signalman clearly, the operator must dog the hoist so that we can correct the
STANDARD SIGNALS USED
So there won't be any
misunderstanding, we use standard hand signals for all hoisting equipment moves.
These signals have been agreed upon by hundreds of construction and industrial
companies, and adopted by the American National Standards Institute (ANSI).
DEMONSTRATE THE STANDARD SIGNALS, OR CALL ON A MEMBER OF YOUR GROUP TO
SIGNALS USED FOR MANY JOBS
In the case we described at the beginning of this talk, a signal was misunderstood and a man killed. The possibility of an accident exists wherever signals are given. This may involve setting off a charge of dynamite, backing a truck, swinging a boom near a transmission line, flagging a railroad crossing, or performing a vast number of operations involving hoists or other equipment. Whether called a signalman, flagman, or spotter, this individual's actions can mean life or death for fellow workers.
