Product Description
Sprayed Insulation Inc. was among the specialty contracting firms that applied spray-on asbestos structural fireproofing to steel-frame commercial high-rise, industrial, and institutional buildings during the peak asbestos-spray era of approximately 1958 through 1973 — the interval bracketed by the first commercial availability of dry-mix asbestos fireproofing products (Cafco Blaze-Shield, U.S. Mineral Products Cafco Spray, W.R. Grace Monokote, and comparable formulations) and the effective ban on spray-applied asbestos fireproofing under EPA’s 1973 National Emission Standards for Hazardous Air Pollutants (NESHAP).
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that spray-applied fireproofing installed by Sprayed Insulation Inc. crews used wet-mix and dry-mix formulations in which chrysotile and amosite asbestos fiber were the principal reinforcing components, delivered by pressurized hose to a spray nozzle and applied at high volume to:
- Structural steel columns, beams, and girders
- Underside of composite steel-and-concrete floor decking
- Bar-joist ceilings and structural framing
- Fluted metal decking in office, retail, and industrial construction
- Fire-rated enclosures around elevator shafts, stairwells, and mechanical penetrations
Spray-applied fireproofing was among the highest fiber-release construction operations of the asbestos era. Plaintiffs allege that spray nozzlemen, mixer operators, adjacent iron and sheet-metal trades, and general-construction workers on the same floor plates were exposed to substantial respirable asbestos fiber loads during application, from overspray drift, and from the rebound and sweep-up of dry fallen material.
Sprayed Insulation Inc. has been named as a defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
