Australian Volunteer Bush Fire Brigades

I just completed the special "out of season" firefighters course at Mundaring. Thanks to the practical and thorough instruction, the course was enjoyable and informative. The "starting" point as with all such things. I nearly came to grief in one section at the assessments. I answered a question wrongly in the section relating to driving although I think this must apply to any aspect of firefighting. "drivers must not operate a FESA vehicle whilst under the influence of alcohol.......to such an extent as to be incapable of having having proper control of the vehicle". My answer was wrong in that I disagreed with the above. I was told that since we are volunteers, the rules applying to paid professionals was relaxed. I think the training manual, Module 7 ought to be revised to say "FESA strongly recommends that NO alcohol etc be consumed whilst the member is 'on call' At the least! That's say one week in four of no red wine, beer, whatever..... Am I alone in this? Bill How much is too much? A perenial question but better to say "zero".
