You should always consider measures that protect everyone who is at risk (collective protection) before measures that protect only the individual (personal protection).
Fall Arrest Equipment
Cleaning windows at height will often require the use of appropriate fall arrest equipment. This is normally a safety harness suitable for fall arrest, connected via an energy-absorbing lanyard, to a suitable anchor point. Harnesses must be adjusted properly to fit the wearer.
Fall arrest equipment must be maintained in good repair, periodically inspected and replaced when appropriate. Equipment which is exposed to conditions causing deterioration which is liable to result in dangerous situations should be inspected regularly and each time exceptional circumstances which might jeopardise safety have occurred.
Anchor points for fall arrest purposes require periodic inspection and testing by a competent person.
You must provide appropriate personal protective equipment (PPE) (* see also our own PPE section) and training in its usage to your employees wherever there is a risk to health and safety that cannot be adequately controlled by other means. Common PPE in the window cleaning industry includes items such as safety helmets and hard hats, gloves, protective footwear and clothing, high visibility clothing.
