8. Haw does the activity impact the hazardous characteristics of the material? Consider vapors released, or hazards otherwise exposed. 9. what must the material be protected from? Consider other mater- ials, temperature, shock pressure, etc. 10. what effects of the material must people and the environment be protected from? 11. How can protection be accomplished? Consider: a. proper containers and equipment, b. separation by distance ar construction, c. enclosure in cabinets or roams, d. spill control, drainage and containment, e. control systems -ventilation, special electrical, detec- tion and alarm, extinguishment, explosion venting, limit controls, exhaust scrubbers, excess flow control, f. administrative ~operatianal} controls - signage, ignition source control, security, personnel training, established proce- dures, storage plans, emergency plans. Evolution of the hazard is a strongly subjective process, therefore, the person charged with this responsibility must gather as much relevant data as possible so that the decision will be justified and within the limits prescribed in laws, policies and standards. It may be necessary to cause the responsible persons in charge to have tests made by quali- f~ed.persons and/or testing laboratories to support contentions that a particular material or process is or is not hazardous. See UFC Section 2.201. IV. LIST OF "EXTREMELY HAZARDOUS SUBSTANCES" AND THEIR THRESHOLD PLANNING QUANTITIES. As established by Superfund Amendments and Reauthorization Act of 1986, published in the Federal Register Vol. 52, No. 71, April 22, 1987, and codi- fied as 40 CFR 355. NOTE: Threshold Planning Quantities TPQ} for solids. Extremely hazardous substances that are solids are subject to either of two TPQs 4e.g., 500/10,000 lbs.}. The lower quantity applies only if the solid exists in powdered form and has a particle size of less than 100 microns, or is handled in solution or molten form, or meets the criteria for a National Fire Protec- tion Association ~NFPA} rating of 2, 3, or 4 for reactivity. If the solid does not meet any of these criteria, it is subject to the higher TPQ.
