We have a client in a Group 2 hanger protected with a closed head wet system, that services helicopters and they drain the tank (100 gallons) but there is still about 1 gallon left in the tank (1%)
NFPA 409 definitions for unfueled aircraft: An aircraft whose fuel system has flammable or combustible liquid removed such that no tank, cell, or piping contains more than ½ percent of its volumetric capacity. Does this mean that they would not be allowed to use this space as a service area because of ½ gallon of fuel. I would assume that the ½% was based on larger quantities of fuel but have not been able to get any answers, any comments. Thank you James Crawford Phaser Fire Protection Ltd.
