As windows cleaner, who works most of the time outside, can face hazards at work sometimes such are slips and trips for example. What are we doing to control the risk? First of all we ensure the surface is non slip. If the surface is slippery, we would use the salt in the working area avoiding the high risk of falling. The most challenging time is in winter as the temperature goes below zero and water freeze on road and pavements. Also we would provide safety cones on pipes and tape hazards for people walk by to spot any potential danger.
