Instruction Manual
The owner or the owner's agent shall be provided with a fire extinguisher instruction manual that details condensed instructions and cautions necessary to the installation, operation, inspection, and maintenance of the fire extinguisher(s).
Fire extinguishers containing water-based agents that have a conductivity higher than 1.00 uS/cm at 25 C (77 F) shall be considered a
conductor of electricity and therefore not be rated Class C
In addition to successfully meeting the requirements of ANSI/UL 711, CAN/ULC-S508
water-based agents shall be tested in accordance with ASTM D 5391, Standard Test for Electrical Conductivity and Resistivity of a Flowing High Purity Water Sample.
