Hazard Ratings of Vapors from Coatings and Adhesives
Many coatings and adhesives have components that are flammable and/or have toxic hazard. When such materials are associated with personal or property injury leading to litigation, there is often the question as to magnitude of hazard. How does the involved material compare to alternative materials suitable for the same task?
This paper presents methods for comparing such materials, using a number of commercial coatings and adhesives as examples for the comparison. The authors present a concept of Flammable Hazard Index whose numbers may range from zero to 20 billion among the population of commercial materials. Inhalation hazards are also compared using a toxic injury potential (TIP), which is the volume of air required to dilute the vapors to permissible exposure limits (PEL) suitable for 8-hour work-day exposure.
