The following illustration is an example of a safe work area. Not
all work areas are the same, but the principles presented here
can be applied to any work area.
A safe work area is divided into four zones:
1. Safe Zone
– The area outside the Work Zone perimeter.
Bystanders or anyone not directly involved with the work
is permitted to be in this area. There are minimal potential
hazards in the Safe Zone.
2. Work Zone
– The area between the Hazard Zone and the
Safe Zone. People assisting with the work who are wearing
the appropriate PPE are permitted to be in this area. Some
limited hazards are present in the Work Zone.
3. Hazard Zone
– The area between the Operator Zone and the
Work Zone. Only people directly involved with the work who
are wearing the appropriate PPE are permitted in this area.
Workers must always make eye contact with the operator
before entering the Hazard Zone. Serious safety hazards are
present in the Hazard Zone.
4. Operator Zone
– The area where an operator must be to
operate the machine. Only the operator is permitted to be
in this area. The operator must be aware of all the people in
the Hazard Zone and make eye contact with workers before
they enter the Hazard Zone.
