Narcogun PD-345 (Keene Corporation)

Product Description

The Narcogun PD-345 was an industrial product manufactured by Keene Corporation, a company with a broad manufacturing portfolio that spanned multiple decades of the twentieth century. Keene Corporation operated across a wide range of industrial product lines, and the Narcogun PD-345 falls within a category of products associated with applications including floor tile, pipe insulation, refractory materials, spray fireproofing, and valves and steam traps. These application categories reflect the industrial environments in which the product was used and the types of worksites where exposure incidents are alleged to have occurred.

Keene Corporation was a significant presence in American industrial manufacturing, and its products were distributed to commercial construction, heavy industry, and manufacturing facilities throughout the United States. The company faced substantial asbestos-related litigation during the latter decades of the twentieth century, which has generated a body of legal documentation concerning its product lines, including products bearing the Narcogun PD-345 designation.

Specific production dates for the Narcogun PD-345 have not been independently confirmed in publicly available regulatory records. Based on the product’s documented industrial applications, its use is consistent with mid-to-late twentieth century construction and industrial manufacturing practices, a period during which asbestos-containing materials were widely specified for fireproofing, thermal insulation, and refractory purposes across American industry.

Asbestos Content

The specific asbestos formulation of the Narcogun PD-345 has not been independently verified in available AHERA or OSHA regulatory documentation at the product-specific level. However, litigation records document that plaintiffs alleged the Narcogun PD-345 contained asbestos as a component material. The product’s association with application categories — including spray fireproofing, pipe insulation, and refractory materials — is consistent with industries and product types in which asbestos fibers, particularly chrysotile, amosite, and crocidolite, were commonly incorporated during the relevant manufacturing era.

Spray fireproofing products of this general type were frequently formulated with asbestos to achieve required fire-resistance ratings and thermal performance specifications. Pipe insulation and refractory materials similarly relied on asbestos fiber content to provide heat resistance and structural durability in high-temperature industrial environments. Plaintiffs alleged that the Narcogun PD-345 shared these compositional characteristics and that its use in industrial settings resulted in the release of respirable asbestos fibers.

Floor tile and valve and steam trap product categories associated with the Narcogun PD-345 designation further reflect the breadth of industrial contexts in which Keene Corporation products were alleged to have introduced asbestos exposure risks. Litigation records document claims that products in these categories contributed to cumulative occupational asbestos exposures among industrial workers.

How Workers Were Exposed

The primary population documented in litigation records as having been exposed to the Narcogun PD-345 consists of industrial workers generally. The product’s multi-category application profile — spanning spray fireproofing, pipe insulation, refractory installation, floor tile work, and valve and steam trap maintenance — indicates that exposure could have occurred across a wide range of industrial job functions and worksite types.

Spray fireproofing operations present well-documented exposure risks. Workers involved in the application of spray-applied fireproofing materials were subject to direct inhalation of airborne asbestos fibers generated during the spraying process. Bystander workers in adjacent trades — pipefitters, electricians, ironworkers, and laborers — present in the same work areas were similarly exposed to elevated airborne fiber concentrations. OSHA records and industrial hygiene literature from the relevant period confirm that spray fireproofing operations were among the highest-exposure activities in construction and industrial settings.

Pipe insulation work involving asbestos-containing materials generated exposure during both installation and removal. Workers who cut, fit, mixed, or applied pipe insulation, as well as those who later disturbed or removed aged insulation during maintenance and renovation activities, faced significant inhalation risks. Friable asbestos insulation materials are known to release fibers readily upon mechanical disturbance.

Refractory installation and repair work in furnaces, boilers, kilns, and industrial ovens similarly exposed workers to asbestos-containing materials. The repeated heating and cooling cycles characteristic of refractory applications caused material deterioration over time, creating ongoing exposure hazards for maintenance workers and repair crews who worked around degraded refractory products.

Floor tile installation and removal activities, including cutting, grinding, and scraping operations, could generate respirable asbestos fiber concentrations when tiles contained asbestos binders. Workers involved in flooring trades in facilities where the Narcogun PD-345 was specified faced exposure risks during both original installation and subsequent renovation work.

Valve and steam trap maintenance activities exposed pipefitters and industrial maintenance workers to asbestos-containing packing, gasket, and insulating materials associated with these components. The repeated disassembly and reassembly of valves and steam traps in industrial piping systems generated localized fiber releases over the course of extended industrial careers.

Plaintiffs alleged that Keene Corporation knew or should have known of the health risks associated with asbestos exposure and that the company failed to adequately warn workers of those risks or to provide sufficient guidance for safe handling of its products.

Documented Trust Fund / Legal Options

The Narcogun PD-345 is a Tier 2 product for purposes of asbestos litigation and compensation. No dedicated asbestos bankruptcy trust fund has been identified as the primary compensation vehicle for claims arising specifically from this product. Litigation records document that claims related to Keene Corporation products, including those in the product categories associated with the Narcogun PD-345, have been pursued through the civil tort system.

Individuals diagnosed with asbestos-related diseases who allege exposure to the Narcogun PD-345 may have legal options through civil litigation against responsible parties. Litigation records document that plaintiffs have brought claims alleging injuries including mesothelioma, asbestosis, lung cancer, and other asbestos-related conditions arising from exposure to Keene Corporation products in industrial settings.

Individuals with potential claims should be aware that asbestos litigation involves statutes of limitations that vary by jurisdiction and typically begin to run from the date of diagnosis of an asbestos-related disease rather than the date of exposure. Prompt consultation with qualified asbestos litigation counsel is advisable to preserve legal rights.

Additionally, because industrial workers are frequently exposed to asbestos-containing products from multiple manufacturers over the course of a working career, individuals alleging exposure to the Narcogun PD-345 may also have claims against other manufacturers and may be eligible to file with one or more asbestos bankruptcy trust funds established by other companies whose products contributed to their cumulative exposure. A comprehensive exposure history review conducted by experienced asbestos litigation counsel can identify the full range of potential compensation sources available to eligible claimants.
