Hazardous materials dealing with

Physical Hazards — are hazards that deal with mechanical, electrical, and hydraulic energy being buried by some material commimication problems noise and entry and exit problems of... 

Flammability and corrosivity may not be the only iiazards presented. It is important to keep in mind the potential for multiple hazards when dealing with hazardous materials. 

The best way to deal with a hazard in a flowsheet is to remove it completely. The provision of safety systems to control the hazard is much less satisfactory. One of the principal approaches to making a process inherently safe is to limit the inventory of hazardous material, called intensification of hazardous material. The inventories we wish to avoid most of all are flashing flammable liquids or flashing toxic liquids. 

There are many sehools of thought on the use of PPE. We will outline and define some of the most important PPEs that should be used when dealing with hazardous materials. 

SARA Title III is intended to help eommunities aeeess information and be better prepared to deal with the presenee of hazardous ehemieals and releases of those ehemieals into the environment. Through SARA, states and eommunities are eneouraged to work together with faeilities to improve hazardous materials safety and proteet publie health. 

The authors believe that although the following information is speeifie to superfund sites, the general findings are universal. As you review this information, you will notiee some areas of bold print. Within these bolded areas, the authors have added their own analysis, eomments, and lessons learned while performing field aetivities at sites of all sizes that deal with hazardous materials. 

A question often asked when dealing with hazardous materials is whether a eertain site is eompliant with the Proeess Safety Management Guidelines as well as HAZWOPER guidelines. In order to answer this question, we have modified a Department of Labor doeument and ineluded it below. Should the reader desire more information on this subjeet, refer to the OSHA web page for the following publieation U.S. Department of Labor Oeeupational Safety and Health Administration 1994.

The Center for Chemical Process Safety s projects fall into a number of general topic areas that comprise a comprehensive program. These topic areas include identification of hazards and analysis of risks, prevention and mitigation of the hazards identified, and better definition of areas affected by a release of hazardous materials. This book is the latest in the series dealing with hazard identification and risk analysis. 

As piirt of each haz, irdous waste remedial action, the contamination at the site must be assessed. The options for remedial action to remo c or otherwise deal with hazardous materials will depend on the nature of the coutamiiuition lliat will be allowed to remain on site tifter cletmup. Thus there must be plans for site remediation to cover any accidental or emergency discharges to land or soils that might develop. 

Obviously, the key word in tliis chapter is identify. Material on identifying healUi hazards can be found in Chapters 9 and 10 of Part III. Tire identifying concerns for tliis cliapter primarily deal with accidents, and tlien accidents can take tlie form of either a chemical release or a disaster arising from a blast/fire/fragnicnt problem. 

The main subject of this chapter is the identification of hazardous chemicals, materials, mixtures, and reaction masses. The chapter deals with undesired decompositions and hazardous reactions. A basic knowledge of the chemistry involved, and, in particular, with the thermodynamics and kinetics, is required. Furthermore, it is important to have a test strategy to recognize and assess the hazards associated with the energetic materials, mixtures, and reaction masses. 

Dealing with the immediate technical causes of a leak, e.g., will prevent another leak for the same reason. If we can use so little of the hazardous material that leaks do not matter, or a safer material instead, as discussed above, we prevent all significant leaks of this hazardous material. If we can improve the management system or improve our designs, we may be able to prevent many more accidents.
