Customers brief:
To provide Stairway access for maintenance personnel to rooftop plant.
Our client, a leading installer of Fall protection equipment was working with a global biopharma to provide safe access for maintenance personnel to their roof top Mechanical & Electrical plant.
The rooftop on their Slough based facility was covered in M&E plant and equipment which requires a program of regular maintenance & inspection. To get across the roof from point of access to area of work, meant traversing numerous ducts, pipework and cabling - all of which presented potential fall or trip hazards to the maintenance teams.

What we supplied:
We worked with the customer to design, in accordance with BS 6375 a range of standard stairs & step units that could be supplied in “Kit” form for their installation on site.
Each kit comprises a range of standard components, these components allow us to economically manufacture a complete range stair & step units, which can then be palletised and shipped to site for lifting to roof level.
With approximately 20 stair / step / plant access platforms to install the customer appreciated this standardised approach to each element as once the method of construction was learnt on the first stair, this process could be repeated on each successive unit.

What We Do

Wherever roof access is required, designers are tasked with creating a safe route to and from the place of work. Following the hierarchy of safety collective protection measures should always be considered above individual fall protection solutions.

D-marc is classed as a form of Collective Demarcation Protection in accordance with the HSE's hierarchy of risk management as set out within the Working at Height Regulations 2005 (WAHR). The WAHR 2005 Part 3 illustrates the use of a demarcation system as an "example of taking other additional suitable and sufficient measures to prevent a fall''. The demarcation system is to be placed a safe distance from the fall hazard (normally >2m). Health and Safety Roofwork HSG33 states that "where work is not done at the edge, demarcation barriers can be provided at a safe distance from the edge (usually at least 2 metres). e.g. work on an air-conditioning unit in the middle of a roof."
