What are flashback arrestors made of?

The simplest flashback arrestor consists of a metallic tube filled with iron wool, which cools the flame below the ignition temperature. In many countries or regions they are mandatory to be installed at the gas regulator or gas outlet/ tapping point.

Are flashback arrestors required by OSHA?

4. Why aren’t flashback arrestors required by law or in the U. S., OSHA safety regulation?

What is the difference between a reverse flow valve and a flashback arrestor?

Reverse Flow Check Valves: Helps to prevent the reverse flow of gases from traveling past the check valve. Flashback Arrestors: Prevents a flame from traveling past the flashback arrestor in the event of a flashback.

Are flashback arrestors reusable?

Flashback Arrestors are designed to stop flashbacks by preventing ignition of mixed gases and to protect equipment such as hoses, regulators, torches and cylinders. Flashback Arrestors are 100% tested, color coded for gas service, and are reusable.

Can you store oxygen and argon together?

These two gases can be stored together. Store flammables in a well-ventilated area away from oxidizers, open flames, sparks, and other sources of heat or ignition. Asphyxiants (including inert gases) can displace oxygen and may cause suffocation.

Are flashback arrestors mandatory?

Because flashback happens too quickly for the gas to be turned off manually before damage occurs, it is essential to have flashback arresters on both gas hoses in all oxy. The OSH regulations require flashback arresters be fitted to each end of the hoses when using pressurised oxygen with a fuel gas.

What is the lifespan of a flashback arrestor?

18 months
The average lifespan of a typical Flashback Arrestor is 18 months, depending on average use, by CGA and OSHA requirements for industrial applications. We recommend testing for flow and reverse flow at least once a year (see product instructions for how to test).

How often should flashback arrestors be replaced?

BOC Flashback Arrestors have to be replaced 5 years from first date of use. A “notched date label” on the flashback arrestor allows the end user to mark the date of first use, providing this is within 1 year of date of manufacture.
