Bob,I don't think the Shirra was any more dangerous to work on than any other job.Carmichael of Edinburgh was the GC.There was a safety meeting every Monday morning in the carpenter's shack,of course,what was said usually went in one ear and out the other,just like the Stewardess before takeoff.The young lady who wrote the Shirra Damm worked on the canteen truck or van which came in from Pitloughry with groceries (tea sugar some meats like steaks bacon eggs).That's where I learned to cook???? The Company(Carmichael)provided the cooked food in a mess hall(canteen) when we came down from the jobsite,if we thought we didn't like what they were serving,that's when we went back to the Nissan Huts where we slept,14 to 16 workers in each and 2 wood and coal stoves and cooked some of what we had bought from the Van from Pitloughry.The work huts Nissan Huts were used originally to house German POWs.There were about 4000 people working on the dam,2000 day shift and 2000 night shift,the busses that took us up in the morning,took back the night shift .I don't want to give too much information,could cause an overload.Besides,it's almost midnight on Friday January 24th.2014.over here in New Haven,Connecticut.Have to great year.Charlie....
