Fire escape stairs are a critical life safety feature of many commercial, industrial and residential buildings. They provide a safe means of escape during an emergency and must remain structurally sound, accessible and safe for use throughout the life of the structure they are servicing.

Unlike internal staircases, external fire escape stairs are often exposed to harsh environmental conditions, including rain, wind, temperature changes and corrosion. Without regular inspection and maintenance, deterioration can develop unnoticed and compromise the safety of building occupants.

At Graham Garner & Partners we provide structural inspections, condition assessments and repair advice for fire escape stairs, access stairs and external steel stair structures.

Why Are Fire Escape Stair Inspections Important?
Many fire escape stairs are constructed from steel, which provides an efficient and durable solution when correctly protected and maintained. However, over time, exposure to the elements can lead to deterioration.

A structural inspection can help identify:

• Corrosion of steelwork
• Deterioration of connections
• Damaged or loose fixings
• Defective stair treads
• Unsafe handrails and guarding
• Excessive movement or vibration
• Structural overloading
• Poor previous repairs

Identifying these issues early can help prevent unexpected failures and costly emergency repairs.

Common Problems Found During Fire Escape Stair Inspections

Corrosion of Steelwork

The most common issue affecting external steel fire escapes is corrosion.

Areas particularly vulnerable include:

• Stair stringers
• Landing beams
• Connection plates
• Bolted connections
• Balustrade supports
• Areas where water can collect

Corrosion reduces the effective thickness of steel members and can weaken the structure over time.

A visual inspection may identify:

• Rust staining
• Flaking paint coatings
• Pitting corrosion
• Section loss
• Distortion of steel members

Where corrosion is identified, further assessment may be required to determine whether repair or replacement is necessary.

Condition of Stair Treads and Landings

Fire escape stairs must safely support occupants during an emergency.

The inspection will consider:

• Condition of stair treads
• Secure fixing of components
• Corrosion beneath walking surfaces
• Deflection under loading
• Condition of landing platforms

Damaged or deteriorated treads can create slip, trip or structural safety risks.

Assessment of Connections

Connections are often the most critical parts of a steel staircase.

A structural engineer will review:

• Bolted connections
• Welded joints
• Fixing brackets
• Connections to the building structure
• Support arrangements

A staircase may appear sound externally while concealed connection issues develop over time.

Handrails and Guarding

Fire escape stairs require suitable edge protection to prevent falls.

Inspections consider:

• Stability of handrails
• Condition of balustrades
• Fixings
• Height and arrangement
• Corrosion at connection points

Loose or deteriorated guarding can present an immediate safety concern.

What Does a Fire Escape Stair Inspection Involve?

A structural inspection typically includes:

Visual Assessment

The engineer will inspect accessible areas of the staircase to identify visible defects and deterioration.

This includes reviewing:

• Structural members
• Connections
• Supports
• Stairs and landings
• Guarding systems

Condition Assessment

The engineer will consider:

• Age of the structure
• Construction type
• Environmental exposure
• Previous maintenance
• Signs of deterioration

Structural Assessment

Where required, further engineering assessment may include:

• Checking member capacity
• Assessing corrosion impact
• Reviewing fixing arrangements
• Providing repair recommendations

Repair and Maintenance Recommendations

Where defects are identified, solutions will depend on the condition and extent of deterioration.

Possible recommendations may include:

Protective Coatings

For minor corrosion:

• Cleaning and preparation of steelwork
• Application of suitable protective coating systems
• Improved maintenance procedures

Steel Repairs

For more significant deterioration:

• Replacement of damaged sections
• Strengthening plates
• Additional support members
• Replacement of connections

Stair Replacement

In some cases, replacement may be the most practical and economical option where:

• Corrosion is extensive
• The structure no longer meets requirements
• Repairs would be disproportionate

Fire Escape Stair Inspections for Commercial Buildings

Fire escape stairs are commonly found on:

• Office buildings
• Schools
• Industrial units
• Apartment blocks
• Hotels
• Commercial premises
• Public buildings

Building owners, landlords and managing agents have a responsibility to ensure that escape routes remain safe and maintained. Regular inspection can help demonstrate that appropriate maintenance measures are being taken.

Why Use a Structural Engineer?

A general visual inspection may identify obvious defects, but a structural engineer can assess the significance of those defects and advise on appropriate action.

A structural engineer can provide:

• Independent assessment
• Defect diagnosis
• Structural calculations where required
• Repair specifications
• Strengthening designs
• Advice on replacement options

This provides confidence that repairs are technically appropriate and proportionate to the level of risk.
