Chemical Energy Density (maximum heat of decomposition constrained only by stoichiometry). For the first criterion, substances are placed in four different hazard classes based on enthalpy of reaction/decomposition as indicated in Table 2.10. 

Several qualitative approaches can be used to identify hazardous reaction scenarios, including process hazard analysis, checklists, chemical interaction matrices, and an experience-based review. CCPS (1995a p. 176) describes nine hazard evaluation procedures that can be used to identify hazardous reaction scenarios-checklists, Dow fire and explosion indices, preliminary hazard analysis, what-if analysis, failure modes and effects analysis (FMEA), HAZOP study, fault tree analysis, human error analysis, and quantitative risk analysis. 

DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE Poison by inhalation. A corrosive irritant to the eyes, skin, and mucous membranes. With the appropriate conditions it undergoes hazardous reactions with formic acid, hydrogen fluoride, inorganic bases, iodides, metals, methyl hydroperoxide, oxidants (e.g., bromine, pentafluoride, chlorine trifluoride, perchloric acid, oxygen difluoride, hydrogen peroxide), 3-propynol, water. When heated to decomposition it emits toxic fumes of POx.

A fluidized-bed reactor is to be designed to destroy 99.99% of a unique liquid hazardous waste. Based on laboratory and pilot plant studies, researchers have described the waste reaction by a first-order reversible mechanism. Their preliminary findings are given below. 

Many hazardous reactions are simply acid/base reactions or redox reactions with concentrated, powerful reagents. 

All hazardous reactions of this compound may be attributed to sulfuric acid, which is generated on hydrolysis, that is, reaction with water. The acid formed, based on its concentration, may readily react with metals (metal containers) and generate hydrogen. This may be hazardous if there is any buildup of pressure due to hydrogen. Also, sulfuric acid can react violently with certain nitro compounds. In the absence of any hydrolysis acid product, the parent ester does not exhibit any violent reactivity with most substances.
