Hazards in an automated storage & retrieval system

The main hazards in an automated storage and retrieval system lies between reception and transfer points. The hazards can also be associated with while the movement of products using the lift trucks or the deployed converyor system.

The main hazards associated with the use of automatic guided vehicles (AGVs) in ASRS system include:

  • Accident with collision between AGVs and human
  • Trapping points between AGVs and stationary objects or fixed structures.
  • Dangerous occurrences by inadvertent movement of the AGV, eg where AGVs interact with storage and retrieval machines. The AGV could move off before the load. transfer is complete, causing displacement or collapse of the load or other devices.

Hazards at transfer points include:

  • Trapping points between mechanical handling devices, palletised loads and the structure of the transfer point.
  • Collapse of the palletised load
  • Trapping points between an automated storage retrieval machine, palletised load, mechanical handling devices and the structure of the transfer point.

Hazards in an automated storage area include:

  • Struck by an automated storage and retrieval machine.
  • Trapping points between automated storage and retrieval machines and fixed structures, eg racking.
  • Trapping points between dangerous moving parts of the automated storage and retrieval machine.
  • Trapping points at transfer points for goods, eg transfer arms, transfer pallets.
  • Trapping points at transfer points for automated storage and retrieval machines which serve more than one aisle (movement of stacker onto transfer bogey, movement of the transfer bogey).
  • Collapse of an automated storage and retrieval machine or load, also part of load topling.
  • Overrun of automated storage machine in horizontal or vertical travel.
  • Inadvertent movement of an the AGV.
  • Accidents during maintenance of the system.
