When it comes to roof safety, you might immediately think of guardrails or lifeline systems. However, the critical role of fixed ladders in providing secure access onto and off roofs is often overlooked
What is a fixed ladder?
Fixed ladders, sometimes called vertical fixed or CAT ladders, are commonly found on commercial and industrial buildings. As the name suggests, they’re fixed to a structure to provide safe access to difficult-to-reach areas.
These include secure access on high buildings, the roof, or for maintenance purposes and internally to access machinery or mezzanine areas. For this blog, we’re looking at fixed vertical ladders for high buildings and safe roof access.
Choosing the right materials
Fixed ladders come in various materials, with aluminium, steel and galvanised steel being the most popular choices. All of these materials offer durability and strength, but galvanised steel has the benefit of corrosion protection, making it ideal for external installations.
Vertical ladder safety measures
Safety is paramount when working with vertical ladders. Before installing a vertical fixed access ladder, you should always carry out a risk assessment. If this shows a ladder is the most suitable equipment, you need to make sure it is specified correctly and fixed securely to prevent movement.
The most recent standard for fixed ladders for high structures is BS 4211:2005+A1:2008 (Specification of permanently fixed ladders), which specifies the requirements for ladders with single-bar rungs and also outlines the safety requirements for ladders.
For example, handrails should extend to at least 110mm above the landing for a safe exit, and a safety cage should be installed when the ladder is more than 2.5m. Safety cages are the preferred option, but if a cage isn’t possible, individual fall protection must be provided.
If your ladder is over 9m high, you will need a rest platform, sometimes called an intermediate landing. This is also a requirement under the Work at Height Regulations, which stipulate that:
“where a ladder or run of ladders rises a vertical distance of 9 metres or more above its base, there shall, where reasonably practicable, be provided at suitable intervals sufficient safe landing areas or rest platforms.”
Ladder protection is not purely about protecting people working with the ladder. You should also stop any unauthorised access. You can do this easily by fitting a locking device to the ladder’s base so that only authorised and fully trained people can access the roof via the ladder.

Ensuring your fixed ladder is safe
Of course, providing safe access doesn’t end once the ladder has been installed. As with any safety equipment, you need to make sure it remains in a safe condition. And that means having it inspected at least annually by a competent person or company.
As well as confirming the integrity of the ladder, these inspections will also check that the ladder has been installed correctly and complies with current legislation. Inspections will confirm that ladder fixings are secure, moving parts, such as safety gates, are in good working order, and that there’s no damage to the ladders’ rung, stiles and hoops.
Elevating roof safety through informed choices
Fixed vertical ladders are a vital component of ensuring an efficient and reliable means of access to a roof or area of height. But only if they are specified and installed correctly and regularly maintained.
By understanding the relevant standards and regulations, different materials and safety considerations building owners and facilities managers can play a crucial role in maintaining a secure working environment for people to access their roofs for various purposes.
