Geoff, SOP's (Standard Operating Procedures) upon turning out to any Industrial or Commercial building dictate that there is a standard plan. 2 Fire Appliances and a tanker here is the norm. In some City Brigades that would be 3 Appliances, a Hose Layer and a Command Unit. Ray (RODALCO) may have different ideas on this because he is in Auckland and he is a Station-Officer. Better to have more Fire-fighters than not enough, try and save a building with no-one protecting the exposures.
