What Is an LSFOH conduit and why is this specification important?

Safety is a key consideration in every electrical installation, particularly in public buildings and high-risk environments. LSFOH (Low Smoke, Fume, Zero Halogen) conduits are designed to enhance fire safety by reducing smoke and harmful gas emissions in the event of a fire.

Unlike conventional conduits, LSFOH conduits contain very low levels of halogens, typically less than 0.5%, and are designed to minimise the release of corrosive gases. This helps protect people, electrical equipment and surrounding infrastructure.

Key Benefits of LSFOH Conduits

·       Low Smoke Emission

LSFOH conduits produce minimal smoke during combustion, helping maintain visibility in enclosed spaces and escape routes. This is particularly important during emergency evacuations.

·       Reduced Toxic and Corrosive Gas Emissions

Their low-halogen composition reduces the release of harmful and corrosive gases, helping protect occupants and sensitive electrical equipment.

·       Flame-Retardant Properties

LSFOH conduits with flame-retardant and self-extinguishing properties help limit the spread of flames, contributing to improved fire safety.

Where Are LSFOH Conduits Used?

LSFOH conduits are ideal for environments where fire safety is a priority, including:

·       Public and commercial buildings

·       Airports and railway stations

·       Data centres

·       Tunnels and underground facilities

·       Hospitals and educational institutions

·       Emergency exits and escape routes

LSFOH Conduit Safety Standards

LSFOH conduit systems are assessed against relevant international standards, including IEC 63355 and IEC 61386. Standards such as IEC 60754 and IEC 61034 are also referenced for evaluating halogen gas emissions and smoke density in cable materials. The applicable standards and test results should be verified for each product.

Choose Safety with LSFOH Conduits

Choosing the right conduit is essential for creating safer and more reliable electrical installations. With their low-smoke, low-halogen and flame-retardant characteristics, LSFOH conduits offer an effective solution for projects where fire safety matters most.

Investing in quality LSFOH conduit systems helps protect people, minimise potential damage and support safer electrical infrastructure.
