Fire prevention: Active and passive method differences

Fire safety is one of the most important responsibilities for any commercial property owner or manager. Across the South East, businesses are placing greater focus on protecting staff, visitors, tenants and buildings from the risks associated with fire. While fire alarms, extinguishers and emergency lighting often receive significant attention, fire doors remain one of the most overlooked yet essential parts of a building’s fire protection system.

Fire doors play a vital role in slowing the spread of fire and smoke throughout a building. When properly installed and maintained, they can help save lives, protect escape routes and reduce property damage during an emergency. However, damaged or poorly maintained fire doors may fail when they are needed most.

At Artius Fire Protection, businesses throughout the South East are supported with professional fire safety services designed to help properties remain compliant, protected and safe for occupants.

What Is a Fire Door?

A fire door is a specially designed door that helps contain fire and smoke for a specified period of time. Unlike standard doors, fire doors are manufactured using fire-resistant materials and fitted with specialist components such as seals, hinges and self-closing devices.

The main purpose of a fire door is to:

  • Slow the spread of fire and smoke
  • Protect escape routes
  • Allow occupants more time to evacuate safely
  • Help emergency services access affected areas
  • Reduce damage to buildings and property

Fire doors are commonly installed in:

  • Office buildings
  • Apartment blocks
  • Schools and colleges
  • Hotels and hospitality venues
  • Healthcare facilities
  • Industrial units
  • Retail premises

Why Fire Door Inspections Are So Important

Fire doors can only perform properly if they are correctly maintained. Over time, wear and tear, accidental damage or poor repairs can compromise their effectiveness.

Regular fire door inspections help identify issues before they become serious safety risks. In many commercial properties, fire doors are used constantly throughout the day, making routine checks essential.

A damaged fire door may:

  • Fail to close properly
  • Allow smoke to spread rapidly
  • Collapse more quickly during a fire
  • Prevent safe evacuation
  • Place lives at risk

Routine inspections help ensure that every component of the fire door remains fully functional and compliant with fire safety standards.

Legal Responsibilities for Commercial Property Owners

Businesses and property owners across the South East have legal responsibilities when it comes to fire safety. Fire doors form part of a building’s passive fire protection system and should be included within regular fire risk assessments and maintenance programmes.

Responsible persons, landlords and employers must ensure that fire doors:

  • Are fit for purpose
  • Remain in good working condition
  • Are regularly inspected
  • Are properly maintained
  • Meet relevant fire safety standards

Failing to maintain fire doors correctly can lead to enforcement action, fines and serious legal consequences if a fire occurs.

Common Fire Door Problems Found During Inspections

Professional fire door inspections often reveal issues that may not be obvious during day-to-day use. Some of the most common problems include:

Damaged Seals

Intumescent and smoke seals help prevent smoke and fire from spreading around the edges of the door. Damaged or missing seals can significantly reduce protection.

Doors Not Closing Properly

A fire door must fully close and latch correctly. Faulty closers or misaligned hinges may prevent the door from operating as intended.

Gaps Around the Door

Excessive gaps between the door and frame can allow smoke and heat to pass through more easily.

Incorrect Hardware

Handles, hinges and locks must be suitable for use on fire doors. Incorrect fittings can compromise safety performance.

Damage to the Door or Frame

Cracks, holes or warping can weaken the door’s fire resistance.

Obstructions

Fire doors should never be wedged open or blocked by furniture or equipment.

These issues can often be resolved quickly when identified early through regular inspections.

Fire Doors and Smoke Protection

Smoke inhalation is one of the greatest dangers during a fire. Fire doors are designed not only to resist flames but also to limit the movement of smoke throughout a building.

This is particularly important in larger commercial properties and multi-occupancy buildings where maintaining clear escape routes can save lives.

Regular inspections help ensure smoke seals remain effective and doors close securely to provide maximum protection.

Supporting Businesses Across the South East

Commercial properties across the South East vary significantly in size, layout and usage. Older buildings, modern office developments, industrial premises and mixed-use properties all present different fire safety challenges.

Professional fire door inspections help businesses identify weaknesses in their passive fire protection systems while ensuring compliance with current regulations and best practices.

Artius Fire Protection supports businesses throughout the South East with fire safety solutions tailored to the needs of each property.

The Importance of Professional Inspections

While basic visual checks can be carried out by staff or building managers, professional inspections provide a far more detailed assessment of fire door performance and compliance.

Qualified fire protection specialists can:

  • Inspect every component of the door assembly
  • Identify hidden defects
  • Assess compliance with current standards
  • Recommend repairs or replacements
  • Provide documentation and reporting

This helps businesses maintain high safety standards while reducing the risk of overlooking important issues.

Fire Door Maintenance and Repairs

Identifying problems is only the first step. Ongoing maintenance is essential to keep fire doors functioning correctly over time.

Maintenance may include:

  • Replacing damaged seals
  • Adjusting self-closing devices
  • Repairing frames
  • Replacing unsuitable hardware
  • Resolving alignment issues

In some cases, older or heavily damaged fire doors may require full replacement to achieve compliance and maintain safety.

Fire Safety Awareness Within the Workplace

Even the best fire doors can become ineffective if staff do not understand their purpose. Businesses should ensure employees are aware that fire doors:

  • Must not be wedged open
  • Should remain unobstructed
  • Should not be altered or damaged
  • Must be reported if faults are noticed

Simple fire safety awareness training can help reduce unnecessary risks and improve building safety overall.
