2 General safety and design considerations
General safety and design considerations
Introduction
Critical factor
To achieve an operational installation which is reasona-
bly safe for all people involved in its use and mainte-
nance, it is necessary to consider certain aspects. This is
done when designing a conveyor system. The chain is
generally the critical factor to consider with guarding.
Safeguarding
All pinch and shear points as well as other exposed mov-
ing parts that present a hazard to people at their worksta-
tions or their passageways must be safeguarded.
Overhead conveyors must be guarded to prevent objects
falling. Cleated conveyor chains are more hazardous in
creating more pinch and shear points than plain conveyor
chains.
Safeguarding can be achieved by:
• Location
Location of the hazardous area away from the area
occupied by personnel, wherever possible.
• Guards
Mechanical barriers preventing entry into the hazard-
ous areas or protecting against falling objects.
• Control devices
Machine controls which prevent the interruption of
hazardous operations/conditions.
• Warnings
Instructions, warning labels, or sound/light signals
which alert to hazardous conditions.
Safeguarding should be designed to minimize discomfort
or difficulties to the operator. Bypassing or overriding the
safeguarding during operation should be difficult.
Warning labels etc. should only be used when all
other means of safeguarding will impair the function of
the installation or are not cost effective.
The degree of safeguarding required should be iden-
tified during the implementation of the essential safety
requirement during the design process.
