FAQs following new rules in Europe covering Alternate Air Sources


Following the publication of an article about changes to the European Standard EN250 covering Alternate Air Sources, we’ve received several questions asking for specific clarifications. We’ve now compiled a list of Frequently Asked Questions and their relevant answers for your benefit, please find them below:

What does this standard apply to?

Regulators manufactured in accordance with the new (2014) version of the standard. The standard is aimed at manufacturers.

How does this affect my/my student/my dive school’s equipment?

Most of the changes and recommendations that may affect PADI members comes under the heading “Information supplied by the manufacturer”. For PADI members, the manufacturer is the best person to ask if you have any questions about specific equipment and how it can be used.

How can I run courses during the winter without students needing a redundant gas source?

Check with your manufacturer – some regulators are rated for colder use.

How can I run the PADI Deep Diver course without students needing a redundant gas source?

The PADI Deep Diver course does not require dives deeper than 30m.

How does this affect local legislation (e.g. HSE in the UK)?

You will need to check with the regulatory body. Just like PADI they have experts who can help with your questions.

If I determine that my students should not be using an alternate second stage during a specific course what are the other options?

Depending on the level of the students and course in question you may consider:

  • Dual cylinder valves (e.g. H or Y valves) where appropriate.
  • A certified assistant and/or instructor carry a redundant cylinder, regulator and SPG.
  • Students’ carry a redundant system e.g. pony cylinder/bailout cylinder
  • Students’ carry double cylinders e.g. sidemount or backmount
