In 1973 there were three ordinary, OH1, 2 & 3, and three extra, EH1, 2 & 3, hazard groups. They were all (respectively) scheduled the same. Area of coverage has no relevance to the schedule itself other than there is a maximum for each group (LH (225 sqft), OH (130sqft), & EH (100 sqft)). There is a schedule for each group for steel and for copper, and a modified schedule for heads covering the floor only, or heads covering the floor and an interstitial space.
