FAQ

What is the function of a flashback arrestor like the SECURISAF BLW O?

A flashback arrestor is a critical safety device used in oxy-fuel welding and cutting. It prevents the flame from traveling back from the torch into the gas hoses and regulators, which could cause an explosion. It typically contains a non-return valve to stop gas backflow and a sintered flame-arresting element to extinguish the flame.

Is this arrestor suitable for fuel gases like Acetylene or Propane?

No, this specific model, designated with ‘O’ for Oxygen (‘Oxygene’), is designed exclusively for use with Oxygen lines. Fuel gas lines require a different type of arrestor, often with left-hand threads and different internal specifications. Always use the correct arrestor for the specific gas type.

What are the recommended inspection and replacement intervals for flashback arrestors?

It is crucial to follow manufacturer guidelines and local safety regulations. Generally, flashback arrestors should be visually inspected daily for damage before use and tested for leaks and proper function annually by a competent person. Many manufacturers recommend replacing them every 5 years, or immediately if they have been involved in a flashback incident.
