Ranking Hazards

Much information can be understood by a review of certain thermophysical properties of materials and mixtures. In comparing the values of heats of reaction, heats of decomposition and CART to values for known hazardous compounds, an estimation of thermal hazard potential can be made. Table A.2 outlines thermal hazard ranking values that could be used in classifying materials and processes based on heats of reaction and CART determinations (Melhem and Shanley 1997). [Pg.23]

The EPA Hazardous Ranking System computes a numerical score for hazardous waste. If the score exceeds a predetermined value, the waste site is placed on the National Priority List (NPL) for Superfund cleanup. Discuss the pros and cons of such a ranking system. Describe a possible situation in which an air contaminant is controlled but the control system used transfers the contaminant problem to another medium, such as water or soil. [Pg.240]

Each material used is given a hazard ranking. [Pg.41]

The scores for each class of material have been grouped together using a weighted average (hazard ranking times mass of material used). [Pg.41]

This example shows the pros and cons of grouping and averaging scores and weighted hazard rankings. Averaging overall scores makes the process seem fairly green, but this may be masking particular hazards associated with specific... [Pg.41]

CERCLA was passed in 1980 to provide a federally supervised system for the mitigation of chronic environmental damage, particularly the cleanup of sites contaminated with hazardous waste. In 1986, CERCLA was amended by the Superfund Amendments and Reauthorization Act (SARA). Each Superfund site has been assessed, characterized, and prioritized based on risk. Potential sites are first screened using a preliminary assessment (PA) sites deemed a significant threat are then evaluated using a hazard ranking system (HRS) to measure the risk of the site relative to that of other potential sites. The most hazardous sites are then placed on the NPL in the order of their potential risk. [Pg.4546]
