Although there is the potential for a complex, multi-dimensional discussion in this area, the identification of chemicals that cause deterministic responses is discussed first, followed by a discussion of identifying chemicals that cause stochastic responses. An additional complexity is that a material may be hazardous due to its physical and chemical form. Thus, an additional section discusses the identification of hazardous chemical wastes, as opposed to their hazardous chemical constituents per se. 

Identification of Chemicals That Cause Deterministic Responses. Hazardous chemicals having a threshold in the dose-response relationship are identified using the following process ... 

Hazard identification for chemicals that cause stochastic responses is concerned with the process of determining whether exposure to a substance has the potential to increase the incidence of stochastic responses. Hazard identification should include a review of the following information to the extent that it is available.

MRLs are, by definition (Chou et al. 1998), substance-specific and do not include effects attributable to interaction (whether additive, synergistic, or antagonistic) with other chemicals or environmental substances. Their relevance to the mission of ATSDR is to assist public health officials in the identification of chemicals/elements of potential health concern at hazardous waste sites. The ATSDR MRL is not intended to be used in the regulatory or site clean-up process, but is instead intended to serve as a basis of comparison with actual measured levels of environmental exposure. Further, the role of informed biomedical judgment is crucial in the application of any MRL, or the media-specific health guidance values (HGVs) derived from them, in any given exposure scenario (Risher and De Rosa 1997). MRLs for a particular substance are based upon the most sensitive effect/endpoint in that portion of the human population considered to be most susceptible to injury from exposure to that substance. Thus, the... 

Hazard assessment of chemicals Experimental testing is replaced by filling in data gaps needed for hazard identification, potency estimation and classification and labeling. 

Warning labels aid in the identification of chemical hazards during shipment. Under regulations of the DOT, chemicals that are transported in the United States must carry labels based on the UN classification. DOT placards or labels are diamond shaped with a digit imprinted on the bottom corner that identifies the UN hazard class (1 to 9). The hazard is identified more specifically in printed words placed along the horizontal axis of the diamond. Color coding and a pictorial art description of the hazard supplement the identification of hazardous material on the label the artwork appears in the top corner of the diamond (Figure 1-6, A).

This chapter consolidates existing DOE and other federal safety and health requirements and National Standards that address the identification of chemical hazards. State and local code requirements are not included. The consolidated requirements addressed here apply to all locations involved in the storage and/or use of chemicals and chemical products (see def).

Fusible Link a mechanical release device actiwited by the heat effects of a fire. It usually consist of two pieces of metal joined by a low melting solder. Fusible links are manufactured as various incremental temperature ratings and are subjected to varying normal maximum tension. When installed and the fixed temperature is reached, the solder melts and the two metal parts separate, initiating the desired actions Hazard Analysis the systematic identification of chemical or physical characteristics and/ or processing conditions and/or operating conditions that could lead to undesired events Hazardous Area, Electrical a US classification for an area in which explosive gas/air mixtures are, or may be expected to be, present in quantities such as to require special precautions for the construction and use of electrical apparatus HAZOP an acronym for Hazard and Operability study, which is a qualitative process risk analysis tool used to identify hazards and evaluate if suitable protective arrangements are in place if the process were not to perform as intended and unexpected consequences were to result...
