\"PP<\/a><\/div>\n

Fire escape stairs create a conflict: they need protection during works, but they must remain fully usable and compliant at all times. Any protection that obstructs or changes the stair is a safety failure, not a specification detail. This article looks at protecting escape stairs without compromising compliance. The focus is keeping the route usable, fire performance and protection that can be removed instantly.<\/p>\n

Compliance outranks protection on an escape route<\/h2>\n

An escape stair must remain usable, unobstructed and compliant throughout the works. If protection conflicts with that, protection loses.<\/p>\n

That rules out anything fixed, anything that narrows the route below the required width, and anything that cannot be cleared immediately.<\/p>\n

A loose-laid rigid PP honeycomb protection board<\/a><\/a> can be lifted quickly if the route is needed, and it lies flat so it does not create a trip edge on a stair.<\/p>\n

Thickness choices from 2 mm to 12 mm<\/h2>\n

On an escape stair, thickness is constrained by the need to keep the going and the handrail clearance unchanged. The thinner end of the 2 mm to 12 mm range is usually appropriate.<\/p>\n

Where materials must be carried up the escape stair, thicker boards protect treads but must be detailed so they do not alter the effective going or create an edge.<\/p>\n

Keeping the route usable and inspectable<\/h2>\n

Confirm the fire performance required for the route before specifying, and keep the documentation with the site’s fire plan.<\/p>\n

Inspect daily, and after any use of the stair for materials, checking that panels have not shifted and that the full width remains available.<\/p>\n

Agree a removal plan: who clears the protection, how fast, and where it goes, because on an escape route that plan is part of compliance.<\/p>\n

How honeycomb board compares with film, cardboard and ply<\/h2>\n

Films and cardboard curl and tear on stair nosings, which is both a trip risk and an obstruction on a route that must stay clear.<\/p>\n

Plywood protects treads but changes the effective going at the nosing and is slow to remove if the stair is needed in an emergency.<\/p>\n

A PP honeycomb board is light, lifts quickly and lies flat, which makes it the safer choice where the route must stay usable.<\/p>\n

A practical trial plan for escape stairs<\/h2>\n

Protect one flight and leave a comparable flight on the current method. Inspect daily and after any material movement, checking route width and panel fixity.<\/p>\n

Time a full removal: clear the protection from the flight and record how long it takes, because that is the compliance measure.<\/p>\n

Record fire performance documentation and keep it with the site fire plan.<\/p>\n

What to include in a protection board enquiry<\/h2>\n

State that the stair is an escape route, the tread material, the required clear width and the fire performance needed. Ask for the thinnest board that resists the expected load.<\/p>\n

Ask for guidance on keeping the route unobstructed and on rapid removal, and about custom cuts for uniform treads.<\/p>\n

Final takeaway<\/h3>\n

On escape stairs, compliance comes first: keep the route unobstructed, use a thin loose-laid board, confirm fire performance and be able to remove it instantly.<\/p>","protected":false},"excerpt":{"rendered":"
