First of all I work at a gas company as a Fire Equipment Maintenance Specialist in Libya. My job is to follow up and assess efficiency of fixed firefighting systems and provide plans for preventative/corrective maintenance/testing based on schedules.
One of our firefighting systems has a foam bladder tank which protects an oil tank and plant operations.
My problem is when we started this project the bladder tank was built out of global standard. The foam concentrate AFFF is stored between the internal tank wall and membrane. Water gets inside the membrane which forces the foam to get out through the rated membrane.
I know it is wrong and does not produce a perfect foam solution within the specification. When I complained about this case, my manager asked me to provide an opinion based on international standards.
Is there guidance within NFPA-standards that can help me address this issue?
