To achieve an operational installation which is reasonably safe for all people involved In its use and maintenance It is necessary to consider certain as pects This is done when designing a conveyor system The chain is gen erally the critical factor to consider with guarding 112 Safeguarding All pinch and shear points as well as other exposed moving parts that pres ent a hazard to people at their workstations or their passageways must be safeguarded Overhead conveyors must be guarded to prevent objects fall ing Cleated conveyor chains are more hazardous and create more pinch and shear points than plain conveyor chains 5814EN 3 1 o General safety and design considerations Flex Link 1 1 2 1 Safeguarding can be achieved by e Location Location of all hazardous areas away from areas occupied by personnel wherever possible e Guards Mechanical barriers preventing entry into hazardous areas or protecting against falling objects e Control devices Machine controls which prevent the interruption of hazardous operations conditions Warning nstructions 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 safe guarding will impair the function of the installation
