E.
ID Credit 1.1: Innovative Design: 1 Credit.
1.
Interchar 212 fire protection material is designed for off-site shop application. Shop application of passive fire proofing addresses the following Green Building concerns:
a.
Significant reduction in on-site water consumption during construction. The application requirements for spray applied fireproofing consume thousands of gallons of potable water for mixing, overspray and clean out. Interchar 212 material is 100 percent solids requiring no water for application.
b.
Significant reduction in job site fireproofing waste generation. Less material is applied on-site to the field joints and touch-up areas.
c.
Significant reduction in the exposure of construction personal to VOCs and potentially harmful construction dust.
d.
Interchar 212 material absorbs less than 1 percent moisture and is not susceptible to damage, thereby eliminating a potential source for microbial contamination.
