2.2.6
Hydrogen Peroxide System
**************************************************************************
NOTE: Edit Section 11242A CHEMICAL FEED SYSTEMS to
provide on-off, set point, or proportional control
as appropriate.
Hydrogen peroxide storage system requirements should
be coordinated with suppliers to ensure material
compatibility. Floating roof manway area should
equal 1 in 2 per 400 L (100 gallons) for solutions
less than 52 percent, and 2 in 2 per 400 L (100
gallons) for solutions greater than 52 percent.
Process safety management requirements must be
followed any time more than 3375 kg (7500 pounds) of
H2O2 is stored, or the solution strength is greater
than 52 percent; refer to 29 CFR 1910.119 for
information.
Hydrogen peroxide storage tanks should be located
outside when possible. Polyethylene should not be
used for peroxide concentrations greater than 52
percent.
**************************************************************************
The hydrogen peroxide storage tank shall be constructed of cross linked
polyethylene, 316 stainless steel, or 99.5 percent pure aluminum alloys
designated in [ASTM B 209M] [ASTM B 209] as 1060, 5254, 5652. Hydrogen
peroxide storage tanks shall be provided with secondary containment [as
detailed on the drawings] [_____] with a minimum capacity equal to [110]
