There are many statutory regulations concerning the material and its use. The most commonly occurring rules are given below. 

Use in general

  • Ensure a stable and flat base. 
  • Take extra precautions if the climbing material needs to be placed in front of a door; prevent the use of the door. 
  • In the case of metal climbing materials look out for non-insulated electrical sources; place the climbing material at least 2 metres from these. 
  • Wear safe footwear, preferably shoes with profiled soles or safety shoes.
  • Use head protection if there is a large chance of hitting your head (safety helmet).

Quality climbing material

  • Check the climbing material before use; note the approval date when doing this.
  • Ensure regular maintenance and inspection by approved experts.

Use of stepladders

  • Ensure that stepladders are fully unfolded. 
  • Do not use the top steps unless you can hold on safely. 
  • A stepladder with platform must have a support brace of at least 60 cm.

Use of ladders
Ladders may only be used for incidental jobs (shorter than 4 hours) in case little strength is needed and the relevant task can be carried out at an arm's length. Otherwise scaffolding or a tower wagon must be used.

  • Place a ladder at about 70º to the ground (a measure for this is: stand upright with the toes against the ladder; with outstretched arms you should just be able to grab the ladder). 
  • Ensure a ladder cannot slip or use a ladder with ladder shoes. 
  • Place a ladder against a firm, weight-bearing surface. 
  • Do not lean too far to one side; work within your span. 
  • Stand with both feet on the ladder. 
  • Use ladders of the right height. The ladder must stick out at least 1 metre above the place where you want to work. 
  • The pull-up rope from an extension ladder must be fixed to a step; the overlap between parts must be at least two steps. 
  • In the case of a three-part combination ladder, which is used as an ordinary stepladder, never climb the third part of the ladder above the pivoting point. 

Use of scaffolding 
When working at a height of 2.5 metres or more, use scaffolding, a tower scaffold, platform or a working floor.

  • Scaffolding may only be erected by an experienced scaffolder. 
  • If there is a chance of electrocution then the scaffolding must be earthed. 
  • Climb the scaffolding correctly. 
  • Material may not be stacked up to more than a height of 0.55 metres on the scaffolding unless fencing is used. 
  • Ensure the stability of the scaffolding by paying due attention to the base, the locking of the wheels and the surroundings (doors, people passing by). 

Safety harness
A safety harness must be worn at locations that cannot be made safe enough, such as work locations at height and sloping roofs.
