Q: When is spill containment required?
A: All states
fire codes require some form of spill containment in a battery room.
Throughout the nation, states will either fall under the International
Fire Code or Uniform Fire Code. Check with your local fire marshal
or building inspector to determine which fire code is applicable
for your battery room. As a general rule of thumb, all wet cell
battery systems require a complete spill containment barrier system.
A complete system consists of 4” high barriers to enclose battery
system at a minimum of 1” beyond the furthest point of rack/cabinet,
acid-resistant flooring and an absorbing & neutralizing method
to a pH range of 7.0 to 9.0.
Q: Is spill
containment required for VRLA battery systems?
A: This is dependent
upon the states’ governing fire code. Keep in mind that additional
measures may be required by the local code ordinances above and
beyond state codes so it is always recommended to check with the
local inspector for verification.
Fire Code (UFC) Article 64 requires a complete spill containment system with 4” high barriers
to enclose any battery system containing 50 gallons
or more of electrolyte in an unsprinklered facility or 100 gallons
or more in a sprinklered facility. This includes VRLA battery systems.
Fire Code (IFC) Section 608 does not require the 4” high containment barriers to enclose VRLA
battery systems, however, neutralization of 3% capacity of
the largest jar IS REQUIRED per Section 608.5.2. Acran’s
Lead-Acid Spill Response Kit PN 5SRK1000 or Deluxe
Ni-Cad Spill Response Kit PN 5SRK2000 will satisfy IFC Section
608.5.2 as well as meet the federally mandated OSHA Standards
29 CFR 1910.120(g)(5), 1910.120(q)(2)(XI), 1910.178(g)(2), 1920.268(b)(2)(i),
Q: Are Acran
spill containment systems designed for retrofit applications and
is the installation difficult?
A: Acran spill containment
systems are favored in the industry for retrofit applications because
of our capabilities to easily install around existing batteries.
Same as with new installations, Acran barriers are installed after
the battery & rack system(s) are in place. Barriers
are adhered to the floor with a novolac
adhesive (5EAK0002) to eliminate need to install barriers prior
to rack system as well as eliminate labor time and cost for precise
spotting, drilling and anchoring. The included one-coat, pour-in,
self-leveling, self-priming, novolac
epoxy (5ECT0100) is poured into the constructed barrier system
and seals the floor and rack anchors for an acid-resistant, liquid-tight,
fire code compliant flooring. (Barrier
Installation Manual) Epoxy can be poured during normal business
hours in an occupied building around existing battery systems because
it has 0 Volatile Organic Compounds (VOCs) and is 100% solid. Fumes
are very minimal and not a risk for fire ignition. Acran’s
provided novolac epoxy meets ASTM D-635 flammability standards and
NFPA Hazards Flammability rating is 0-1. For Reference
Please See ACRAN's MSDS Page.
Q: Are Acran
spill containment systems UL Listed or Recognized?
A: No. Because there is no UL Standard
for spill containment, Acran systems
are not UL Listed or Recognized. Manufacturers offering UL Listed/Recognized
systems merely supply a system in which UL tested and confirmed
that the performance of the specific product meets the scope of
work as provided by the submitting manufacturer. Acran systems
are guaranteed 100% compliant with all current federal, state and
local governing agency requirements, including IFC, UFC, NFPA and
Q: Epoxy vs.
Liner – which is better?
A: Epoxy is
the industry standard for liquid-tight, acid-resistant applications
withstanding 98% sulfuric acid – splash, spill, fumes, 70% sulfuric
acid under continuous emersion and meets all current local, state
and federal regulatory requirements including IFC, UFC, NFPA and
OSHA. Acran’s novolac
epoxy floor coating (5ECT0100) and adhesive
gel (5EAK0002)contains 0 Volatile Organic Compounds (V.O.C.s
) and is safe for installation in an occupied building during normal
business hours. The 1 coat, self-leveling, pour-in application
has a thickness of up to 125 mils with flexural strength of 11600
psi, tensile strength of 4000 psi, 21% elongation and compressive
strength of 10500 psi for maximum assurance of acid-resistance and
sustainability during minor seismic occurrences. Because Acran’s
epoxy based system can be installed around existing systems without
disruption to the battery system, it is perfect for retrofit applications.
The liner based systems are designed to be installed prior
to the rack system, therefore, retrofit applications either
require moving the existing racks or precise and skilled cutting
and heat resealing of the liner material. Since there is no proven
data on maintaining strength & corrosion resistance on resealed
liner, this introduces a potential point of failure, if not properly
sealed. Annual maintenance mandated by UL to insure liquid-tight
& UL compliance results in recurring maintenance costs for the
life of the spill containment system. The bottom line? Acran’s
0 VOC novolac epoxy spill containment system can be installed during
normal business hours in an occupied building by any qualified contractor
with no annual inspection or on-going maintenance costs. Liner
systems require specialized or trained contractors which causes
additional costs in installation training and annual maintenance
expenses to insure continued effectiveness. For Reference, Please
