Hand
signals are an ideal communication tool when working around
noisy farm machinery. To help everyone communicate in the
same "language," the American Society of Agricultural Engineers
has adopted 11 uniform hand signals for agricultural safety.
These
signals should be learned and used by the farm family, employees
and farm visitors such as feed truck drivers, chemical salespeople
and Extension agents.
Using
standard signals can help:
- save
time
- prevent
accidents
- reduce
severity of injuries
- lower
the risk of accidental death.
Detailed
instructions for performing the 11 signals shown in are presented
below.
