5706.4.10.7 Periodic tests.

Fire extinguishing systems, fire protection systems and tank overfill protection shall be tested once every 2 years at the owner's risk by his or her representative before a representative of the department. Tests of foam extinguishing systems shall produce foam at the most remote tank and produce water flow at each tank. In the event that the discharge of foam to the most remote tank would result in a reportable hazardous material release in accordance with federal, state or local laws, rules or regulations, such other test acceptable to the commissioner may be conducted.

5706.4.10.8 Color coding and labeling.

Fire protection systems shall be color-coded and labeled in accordance with FC 5706.4.10.8.1 through 5706.4.10.8.2. Copies of the color code shall be posted in all central locations for fire extinguishing media, such as the foam house location.

5706.4.10.8.1 Color coding.

Fire protection systems shall be color-coded as follows:

   1.   Standpipe and/or yard hydrant systems:

      1.1.   Piping, valve bodies and handles, hydrants and hydrant or hose houses: Red with contrasting white bands.

      1.2.   Fire department connections: Red.

   2.   Sprinkler systems (wet or dry):

      2.1.   Piping and valve bodies and handles: Red with contrasting bright green bands.

      2.2.   Fire department connections: Red with green caps.

   3.   Nonautomatic sprinkler systems (including fog spray systems):

      3.1.   Piping and valve bodies and handles: Red with contrasting aluminum bands.

      3.2.   Fire department connections: Aluminum.

   4.   Carbon dioxide extinguishing systems – piping, valve bodies and handles: Red with contrasting brown bands.

   5.   Steam extinguishing systems – piping, valve bodies and handles: Red with contrasting black bands.

   6.   Foam extinguishing systems:

      6.1.   Piping, valve bodies and handles, hydrants and hydrant or hose houses: Red with contrasting bright orange bands.

      6.2.   Department water connections: Red. A durable sign that reads "WATER FOR FOAM SYSTEM", shall be conspicuously posted immediately adjacent to such connections.

      6.3.   Department foam connection: Red with contrasting bright orange band or caps. A durable sign that reads "CHEMICAL FOAM DIRECT TO TANKS" or "...% MECHANICAL FOAM SOLUTION DIRECT TO TANKS", shall be conspicuously posted immediately adjacent to such connections.

5706.4.10.8.2 Labeling.

Bands, or piping immediately adjacent to bands, shall be labeled to indicate the names of the extinguishing media. The letters shall be in a contrasting color of a suitable size in proportion to the pipe diameters. The width of each band shall be not less than the pipe diameter and shall be spaced not more than 30 feet (9144 mm) apart. Bands, lettering and piping shall be painted in sun- and weather-resistant colors and paint; but bands and lettering may be applied by means of pressure sensitive tape that is sun- and weather-resistant.

5706.4.11 Interconnected piping.

All tanks shall be connected by a system of steel pipes in a manner that the contents of each tank may be transferred to another tank without resulting in product contamination, or flash point reduction of the stored liquid.
