A building’s fire protection system is designed around its layout, use and contents.

Even a small alteration can affect how fire and smoke move through the building or how sprinkler water reaches the protected area.

Common Building Alterations

Changes that may affect fire protection include:

• Installing a new partition wall
• Moving storage shelves
• Adding a suspended ceiling
• Changing room use
• Creating a new office
• Extending a storage area
• Installing large equipment
• Altering ventilation systems
• Adding decorative features

These changes should be reviewed before work begins.

How Partitions Can Affect Sprinklers

A new wall can change the size and shape of a room.

This may affect sprinkler spacing and coverage. A sprinkler that was suitable for the original open layout may not provide the same protection after a partition is installed.

Professional advice should be obtained before changing room divisions.

Storage Changes Can Create New Risks

Storage arrangements can change the fire load within a building.

Higher shelves, tightly packed goods and new materials may increase the amount of heat produced during a fire. Storage should remain within the conditions considered during the sprinkler system design.

Suspended Ceilings and Decorative Features

Ceilings, bulkheads, beams and decorative structures may affect sprinkler discharge.

A new ceiling feature can obstruct water or create an area where heat collects differently. This may require changes to the sprinkler layout or the addition of further protection.

Changes to Room Use

A room may be used differently over time.

An office could become a stockroom, a storage area could become a workshop, or a meeting space could become a commercial kitchen.

Different uses create different fire risks and may require a review of the existing protection.

Do Not Move Sprinkler Heads Without Advice

Sprinkler heads should not be moved, covered or painted during building work.

Even a small adjustment can affect the system’s coverage and performance. Any changes should be planned and completed by a competent fire sprinkler professional.

Protecting Pipework During Alterations

Pipework above ceilings or within service areas can be damaged during drilling, cutting and installation work.

Before work begins, contractors should identify the location of sprinkler pipework and avoid accidental damage.

Reviewing the System After Work

After an alteration, the sprinkler system should be checked to confirm that:

• Sprinkler heads remain unobstructed
• Pipework has not been damaged
• Valves remain correctly positioned
• Coverage remains suitable
• New ceilings have been considered
• Storage does not block discharge
• System records are updated

Why Early Advice Helps

Getting professional advice before work begins can help prevent delays and unnecessary costs.

It is usually easier to design fire protection into an alteration before walls, ceilings and equipment are installed.

Building Owners and Facilities Teams

Building owners should make fire protection part of their alteration approval process.

Facilities teams, contractors and designers should communicate before changes are made so that the sprinkler system and other fire safety measures are properly considered.

Conclusion

A small building alteration can change the way fire protection performs.

Reviewing the sprinkler system before changing layouts, storage, ceilings or room use can help maintain suitable protection and avoid costly corrections later.
