Stacking and Storing of Articles

Whatever the nature of your business, it is likely to involve the stacking and storage of goods and materials.
Supervision over stacking and correct storing. Stacking may only be permitted if it is under the supervision of a competent person.

Stacking requirements

The base is level and capable of carrying the weight of the stack.
The lower levels are capable of carrying the weight of the upper levels.
Single tier articles are uniform in size, shape and mass.
Pallets and containers are in good condition.
Support structures are sound, solid, and able to sustain the weight.

Other important aspects that must be carried out during stacking

  • Articles may only be removed from the topmost tier.
  • No person may climb on the stack unless it is stable and the person uses a ladder or other safe means.
  • The maximum height that the stack may be raised is 3 times the minimum base width.
  • An inspector may grant permission to stack otherwise by means of an approval notice.
  • Chemicals, explosives and other hazardous materials must be stored in appropriate containers and comply with any legal requirements. 
  • All storage areas should be inspected regularly.

Basic stacking and storage rules

  • Don't store flammable items close to naked light or fluorescent source. 
  • According flammable material should not be close to any from any light (other than cold or fluorescent lighting) or less than 2m away from any electrical distribution board.
  • Make sure there's adequate clearance between freestanding stacks to allow for access and fire control.
  • Always adhere to the principle of good housekeeping! There's a place for everything and everything must be in its place at all times.
  • Stack rack in storerooms, cold rooms and chill rooms with the sides of the stack either vertical or slightly stepped.
  • Never allow any overhang. And never step forward from top to bottom over aisles or in areas where an article from a stack can fall to a lower storage level.
  • Stack drums, other than those containing flammable liquids, on pallets. Check the drums if they're being stored on their sides.
  • Store gases, tyres, oils, styrene, packaging and similar combustible materials separately and not near ignition sources.
  • Regularly refer to local or provincial ordnances and Gazettes for information on quantities of flammables that can be stored, the requirements for inflammable stores, and local authority permits.
  • Usually a permit is required when the amount stored exceeds 1000l.
  • Store pipes and bar stock on cross braces or racks with retaining uprights.
