Hazard, definitions

The flash point of PPS, as measured by ASTM D1929, is greater than 500°C. Combustion products of PPS include carbon, sulfur oxides, and carbonyl sulfide. Specific hazards are defined by the OSHA Hazard Communication Standard (158). Based on information in 1995, PPS does not meet any of the hazard definitions of this standard.

Safety hazards related to the physical characteristics of a chemical can be defined in terms of testing requirements, such as ignitability however, health hazard definitions are less precise and more subjective. There have been many attempts to categorize effects and to define them in various ways. Generally, the terms acute and chronic are used to delineate between effects on the basis of severity or duration. Acute effects occur rapidly as a result of short-term exposures. Chronic effects occur as a result of long-term exposures.
