Changes to Medical Gas Cylinders
The Australian New Zealand Industrial Gas Association has advised that key changes to medical gas cylinders will come into effect on 1st May 2010. These changes affect the identifying colour coding of medical gas cylinders and the introduction of pin-indexed valves on the large medical oxygen gas cylinders.
The adoption of the pin-index valves for the large (Size D,E, G and cylinder packs) medical oxygen cylinder will provide the same pin-indexing system used for many years on the smaller medical oxygen cylinder (Size C, BL). The amendment to the Australian Standard (AS2473.3) will prevent the risk of connection of medical oxygen gas delivery systems to industrial gas supplies.
In Western Australia all medical oxygen cylinders supplied after the 1st May 2010 will be fitted with pin-indexed valves. Compatible pin-indexed oxygen regulators and manifold systems will be required at this time. The conversion of medical oxygen manifolds also provides the opportunity prior to the change over date to ensure these systems are compliant with the Australian Standard (AS2896-1998). The Australian and New Zealand Industrial Gas Association have reported that many manifold installations now in service may be unsafe (ANZIGA Safety Advice No.17 Issued August 2009). Oxygen delivery systems and in particular higher pressure systems present a fire risk if not correctly engineered. Competent organisations must be engaged when work on medical gas systems are their accessories.
Sites, departments, medical practices and home care patients where medical gas supplies, in particular oxygen, are used.
The aim of this circular is to ensure that all relevant departments are aware of these changes and have made the necessary provisions in advance of 1 May 2010.
Key changes to valves of large medical oxygen gas cylinders:
Threaded (bull-nosed) Oxygen Regulator and Pin-Index Yoke adaptor
Pin-Indexed Oxygen Regulator
Key changes to manifold installations:
Key changes to colouring of medical gas cylinders:
The Australian Standard which defined the labelling and colour coding for gas cylinders has recently been amended with the aim of better differentiating between medical and industrial gas cylinders. This now requires that medical gas cylinders have a white cylinder body colour. The type of gas in the cylinder will be identified by the colour on the shoulder of the cylinder. Labels attached to the cylinder should always be read to confirm the cylinder content. Medical oxygen cylinders will be identified by their all white shoulder and cylinder body. The new colour scheme will be indicated by the letter ‘N’ marked twice on the shoulder of the cylinder. (N denotes the new colour scheme). The changes to the colour scheme apply to both small and large medical cylinders.
These changes come into effect 1 May 2010.
The logistics of the change over to pin-indexed bottles and the provision of the correct regulators and manifolds should be considered to avoid disruption to services.
Replacement pin-indexed regulators may be purchased (approx $280 each). Newer threaded (bull-nosed) regulators may also be adapted by a qualified service organisation with the removal of the threaded bull-nose connection and the installation of a pin-indexed yoke (approx $140 each Medical Sales & Service).
