Protect your property from the risks of electrical fires with appropriate fire stopping and electrical penetration measures from J.S.O Fire Safety Consultants.

Fire stopping services for electrical penetrations

Every penetration through a fire-resisting wall or floor creates a potential route for fire and smoke to spread throughout a building. Without suitable fire stopping, the effectiveness of compartmentation can be significantly compromised.

Our fire stopping services are designed to restore the fire integrity of walls and floors where electrical services have been installed.

Our services include

  • Fire stopping around electrical cables

  • Cable tray and trunking fire sealing

  • Conduit penetration fire protection

  • Fire-rated sealing systems

  • Compartmentation reinstatement

  • Fire stopping inspections and surveys

  • Remedial fire stopping works

  • Compliance reporting and recommendations

Who we work with

Electrical systems are a common source of fire risk when installations are poorly maintained or incorrectly protected. Fire stopping forms an important part of a wider electrical fire safety strategy by ensuring penetrations do not create vulnerabilities within the building’s fire protection measures.

  • Commercial premises

  • Industrial facilities

  • Educational buildings

  • Healthcare environments

  • Residential developments

  • Public sector properties

  • Refurbishment and construction projects

FAQs

Fire stopping FAQs

What is fire stopping for electrical penetrations?
Fire stopping for electrical penetrations involves sealing openings created when cables, conduits, trunking or other electrical services pass through fire-rated walls and floors. The purpose is to restore the fire resistance of the compartment and prevent the spread of fire, smoke and hot gases.
Why is fire stopping important around electrical cables?
Electrical penetrations can create gaps that allow fire and smoke to travel rapidly between compartments. Proper fire stopping helps maintain the building’s fire strategy, protects escape routes and improves the safety of occupants during an emergency.
Is fire stopping a legal requirement in the UK?
Yes, fire stopping plays an important role in wider fire safety requirements under UK Building Regulations and fire safety legislation. Responsible persons, building owners and contractors must ensure fire compartmentation remains effective and that penetrations through fire-resistant elements are appropriately protected.
