Application decisionsMap conveyor hazards to the tasks people actually perform
A conveyor safety project needs the whole route, including transfer points and neighbouring equipment. Safeguards must be selected through a competent, site-specific assessment; these questions help prepare that assessment.
Decision 1Identify accessible moving interfaces
Mark drives, rollers, return sections, transfers and interfaces with other machines on the layout. Record access from the sides, below and from platforms, including where an operator may reach to recover a fallen product. Guarding only the most obvious drive can leave another reachable hazard. Include normal use and foreseeable cleaning or fault-recovery tasks in the survey.
Decision 2Separate product access from people access
Describe each opening by its purpose: loading, product discharge, inspection, cleaning or maintenance. A product-transfer opening can also create an access route towards a hazard. State the range of packs using it and the frequency of intervention. The competent designer needs these details to compare physical guarding and suitable protective measures without compromising the intended task.
Decision 3Review stopping across connected sections
A stopped conveyor may still receive material from an upstream machine, while neighbouring equipment continues moving. Define the boundaries and consequences of each stop with the controls team. Record existing drives, safety devices and interface information. Safety behaviour must be assessed as part of the connected installation, not assumed from an emergency-stop button being present.
Decision 4Plan cleaning and blockage recovery
Record where debris accumulates and which tasks currently cause guards to be opened or removed. Most maintenance should use suitable isolation, including stored-energy considerations. Agree safe access and an isolation procedure with the responsible site team before the work is performed. A routine need to reach into a running conveyor is a design issue to resolve, not a normal operating workaround.
Decision 5Consider reset and visibility
Show where people can stand within or beside the guarded route and which areas the operator can see. Document the intended response after access, power loss and a cleared blockage. Reset and restart functions must be designed for the assessed hazards. The survey should also consider escape, lighting and whether a long or divided conveyor hides an occupied area.
Decision 6Request an installation-specific handover
The project brief should identify the altered sections, interfaces, safety functions, drawings and validation responsibilities. Agree the inspection and test records required before use, together with instructions and maintenance access. HSE machinery-safety guidance provides a useful starting point, but the selected arrangement and required performance must be established for the actual conveyor and tasks.
