Working at Height Regulations 2005

The key issues for rooftop maintenance are summarised as follows:

The ‘duty-holder’ is responsible for minimising risk utilising the methodology stipulated in the ‘Hierarchy of Fall Protection’. The risk assessment and the action taken should be proportionate to the harm that could occur.

Working at height is defined as ‘all work activities where there is a need to control a risk of falling a distance liable to cause personal injury’. This means that if there is a chance of a fall of any distance the duty-holder must show that everything has been done to minimise the risk.

The duty-holder must make sure the equipment specified is suitable for the particular use envisaged. It is critical to identify the difference between fall arrest and fall restraint.

Inspection and maintenance are required to ensure that equipment is safe to use. The maintenance schedule will depend on the equipment, the conditions in which it is used and the manufacturers’ instructions.

The following legislation should be taken into account when addressing the issue if working at height.

Health & Safety at Work etc. Act 1974

This is an “Enabling Act” which imposes a duty of care on everyone at work related to their roles. This includes employers, employees, owners, occupiers, designers, suppliers, manufacturers and the self employed.

Section 2 concerns the main duty of employers to ensure the health, safety and welfare at work of the employees by providing a written health and safety policy; safe plant and system of work and to provide information, training and supervision.

Sections 3 – 5 details an employer’s duty to ensure that people not in their employment are not exposed to risks to their health and safety. There is also a general provision for monitoring both employees and persons not in their employment to ensure compliance through method statements, risk assessments and general health and safety policies for completing a specific activity. This includes contractors working on their premises.

Section 37 covers the personal liability of Directors. If an offence is committed by a corporate body or can be attributed to the neglect of a director or other senior officer of that corporate body, both the corporate body and the person are liable to prosecution.
