Section 5.5 of Worksafe's guide for Gas Cylinders provides a bit more details for "when, where and what"The BOC Guide (thanks for sharing Steve) is well laid out and contains good information. It references, value guards, rings and caps, however is quite silent on when where and what. — Matthew Bennett
While it is implied that not all of these need to be done (with the "or" at the end) the question to the supplier if their intended method of protection is to ensure the cylinders are chained up is what is the plan for a case like the linked video when a cylinder is being moved and potentially left to stand unsecure for a moment while doing so?It is important that all users of cylinders take appropriate steps to ensure that
cylinder valves are protected against damage.
Examples of appropriate steps include:
a. Valve protection rings, where these form part of the cylinder design
b. Vented valve caps, where threaded provision for these has been provided
c. Protecting the tops of cylinders during transport and handling, or
d. Securing tall cylinders during transport and storage to prevent them from toppling.
Are they misunderstanding the purpose of the threaded valve guards/caps? My understanding is these are installed when the cylinders are being transported/moved (and therefore not chained up), not when they are in use. Once in position and secured, the cap can be removed and regulator fitted.1) valve guards are useless because you can't attach a regulator to the bottle — Matthew Bennett
