Operational Procedure – Cleaning Windows 

 

47 

Experience will lead to the user developing correct pole technique, in time operators will learn 
to use the stored energy in the pole. Downward movement of the pole will cause the pole to 
bend, as the pole seeks to straighten itself, using the spring in the pole will help the operator 
to raise the pole. The operator controlling the pole urge to fall due to gravity side to side 
motion rather than physically pushing and pulling the pole from left to right. Beginners’# tend 
to use their arms to move the pole up and down, whilst old hands simply sway/rock or step 
forward and back. It is worth remembering that poles feel heavier when used at a steep angle 
and lighter when standing further back from the building at a shallower angle. 

   

Manual  Handling

   

It is natural to operate a waterfed pole by movement of the arms alone and this is acceptable 
for poles that extend to a height of 10 m. For waterfed poles that extend beyond 10 m, 
excessive strain may be exerted upon the upper body when operated for extended periods. 

   

It is recommended that when operating poles that extend beyond 10 m use of arms be 
reduced by greater use of leg/whole body movement. With experience comes the ability to 
work with the natural balance of the pole, less effort is expelled once the operator has 
mastered the balance of the pole, less effort is expelled once the operator has mastered the 
balance technique and has learned to use the stored energy generated in the pole as it is 
guided through the cleaning task. Even with the benefit of training these techniques take time 
to master and they are easier to acquire when shorter poles up to 10 m are used. It is 
important both for the development of new skills and in order to deliver acceptable cleaning 
standards, that new staff become experienced using short poles before moving up to poles 
that extend above 10 m. 

   

Safety  in  Window  Cleaning

   

Scope

   

For the purpose of this guidance, the term “waterfed pole” is defined as a telescopic pole 
fitted with a brush and a means of delivering pure water for window cleaning. 

   

   

The use of pure water is an integral part of the cleaning process. The term “Load” is defined 
as the water treatment system/water delivery tank, waterfed poles and other ancillary 
accesories such as hose reels and warning signs.

   

   

Avoiding Risk

   

The use of waterfed poles removes the need to work at height and provided the window to be 
cleaned can be viewed from the ground without obstruction, it is possible to clean using a 
waterfed pole. Although adopting waterfed pole use may remove the risks involved when 
working at height consideration must be given to both operational risks that apply to waterfed 
pole use.

   

   

When assessing operational risks consideration must be given to the location of the building, 
its design, terrain underfoot, weather conditions and overhead power sources. The 
sustainability of staff with regard to their level of fitness and medical history and the need to 
identify and muscular or skeletal disorders that may develop as a result of operating a pole 
with poor technique. 

   

Less obvious risks include the consequences of carrying heavy tank systems when a vehicle 
is involved in a road traffic accident, as well as the potential for the spread of legionella 
disease cause by poorly maintained filters. 

   

Buildings on industrial sites and domestic properties present different risks than those in busy 
town or city locations where consideration must be given to the time of cleaning of traffic 
conditions. But generally warning signs should be deployed to warn of trip hazards presented 
from trailing hoses and the slip hazard presented by wet pathways. While Hi-viz clothing 
should be worn by operators, especially during winter months and when working in proximity 
to roadways.
