Alternative for: ODSs and propane expanded insulating foams
Applicable EPCRA Targeted Constituents: Class I and Class II Ozone Depleting Substances
Overview:

Expanded insulating foams have become popular with the evolution of building codes in the last several years. Codes now require impervious protection between certain walls and structures to improve fire resistance. These foams can be applied where and when needed. However, ODS and propane-free substitutes are preferable.

Expanded insulating foams are an important part of new building construction, given strengthened building codes. These foams are used to seal holes between walls especially where pipes or conduits penetrate the walls. Since the expanded foams are made from isocynate materials, no isocynate-free substitutes exist. Some foams may, however, contain more innocuous propellants than propane and ODSs, but these are not readily available.

Fire stop compounds are acceptable alternatives to expanded insulating foams and should meet the latest building codes. The only application in which a foam would normally be required is where an object passing through a wall or floor will shrink in a fire; for example, polyvinyl chloride piping. However, the expanded foam can be avoided in this case also by wrapping an intumescent collar around the pipe and applying a fire stopping joint compound around the annular opening.
Compliance Benefit:

Use of an ODS-free fire stop compound in place of insulating foam will help facilities meet the requirements under 40 CFR 82, Subpart D and Executive Order 12843 requiring federal agencies to maximize the use of safe alternatives to class I and class II ozone depleting substances, to the maximum extent practicable.

The compliance benefits listed here are only meant to be used as a general guideline and are not meant to be strictly interpreted. Actual compliance benefits will vary depending on the factors involved, e.g. the amount of workload involved.
