Hair of the Red Dog – AS5034 Compliance in Beverage Dispensing

In our latest blog we take a look at the AS5034 compliance matrix – which highlights gas monitoring in reference to beverage dispensing in Australia.

Most of you will have heard the saying ‘the hair of the dog’, which refers to having an alcoholic drink to cure a hangover, but do you know where this expression comes from?

The saying is actually a shortening of ‘the hair of the dog that bit you’, and comes from the belief that someone bitten by a rabid dog could be cured by placing the dog’s hairs in the wound. This ‘like for like’ principle is applied to alcohol, with the suggestion that drinking a small portion of it usually in the morning after consuming too much will cure a hangover.

If you’re from Australia you might even consider saying ‘the hair of the Red Dog’ to honour the famous kelpie/cattle dog cross. For those unfamiliar with this term, the Red Dog refers to a dog born in the 1970’s who travelled through Western Australia’s Pilbara region hitching rides, befriending people and uniting communities. Books and movies have been even produced about him, and there is a statue of the dog in Dampier.

This is one of many interesting facts about Australia, but there’s also a lot of myths that people believe thanks to false advertising.

For example, while Foster’s lager is largely promoted as the quintessential Australian beer brand, it is actually not that popular Down Under, and Castlemaine XXXX is one of the preferred draught brands.

Also an often quoted phrase associated with Australia is ‘throw another shrimp on the barbie’, which was used in a series of TV adverts by the Australian Tourism Commission starring Paul Hogan.

Australians actually use the word prawn rather than shrimp, but the adverts were commissioned for broadcast in the United States, so the word was changed to cater for the American audience.

Now that you know a little bit more about Australia, it’s time to take a look at the gases used to dispense beverages.

Gases used in beverage dispensing

Carbon dioxide (CO2) and nitrogen (N2) are used to carbonate and deliver beer and soft drinks. They are usually piped and stored in areas such as cellars, breweries and fast food restaurants. These gases are odourless, colourless and tasteless making them hard to detect, and a leak of either of these gases can cause asphyxiation.

CO2 is present in the air at 0.04%, and an increase in this level can lead to several different physiological effects such as drowsiness, reduced hearing, dizziness, confusion and unconsciousness. N2 makes up 78% of the atmosphere, but it does not support human breathing, so if it leaks it will displace oxygen (O2) in the air and cause O2 deprivation.

To ensure the safety of those operating compressed inert gas systems and equipment for beverage dispensing, a new standard was established in Australia.

The ‘AS5034-2005: Installation and use of inert gases for beverage dispensing’, highlights the compliance that needs to be adhered if you use inert gases to dispense beverages in Australia.

Under ‘Section 4 Location and Ventilation of Supply Systems’, the standard states that gas monitoring needs to be considered for non-naturally ventilated areas such as underground cellars and cool rooms.

To help you comply with this section, Analox offer gas monitoring products for both O2 and CO2 detection, to keep you, your staff and your customers safe.

Below is a compliance matrix which details how Analox’s A50 and the new Ax60+ meet each requirement of Section 4. We’re not one to blow our own trumpet but not only do we meet all of the criteria of the standard – our new Ax60+ comes with a five year electronics and CO2 sensor warranty and it’s splashproof. What more could you want?

Compliance Matrix AS5034 – 2005

Analox A50 & Ax60+

Date review completed: 18/08/16

The following compliance matrix details how Analox products can help to deliver a gas system that is compliant with the requirements of AS5034-2005.  Only clauses from AS5034 that relate to Analox gas sensors have been extracted.  The other clauses of AS5034 are considered to be outside Analox’s scope of supply.
