Disposal hazard analysis

Disposal Through a Contractor - A contractor may be used for the disposal of the waste chemicals. Remember that you must keep documentation of your hazardous waste disposal for at least three years. This information must include a waste manifest, reclamation agreement or any written record which describes the waste and how much was disposed, where it was disposed and when it was disposed. Waste analysis records must also be kept when making a determination is necessary. Any unknown chemicals should be considered hazardous ... 

Examples of commercial applications are scarce up to now (cf Section 5.3 use of ILs has been considered for a series of specific questions). The scaling-up of IL syntliesis procedures is normally without problems however, the commercialization and/or transport of the ionic liquids raise the question of their registration (EINECS for Europe or equivalents see Section 5.4). Disposal and recycle of ILs are important concerns and have to be considered on a case-by-case basis. And Ionic liquids are not always green - as has been stated by Rogers et al. [42], From the standpoint of life cycle assessment and hazard analysis ILs are clearly not recommendable for industrial use, especially if those with PFg or BF4 as anions are concerned. And it is obviously no wonder that recent new developments such as BMIM octylsulfate have been emphasized as even greener ionic liquids [43],... 

Use of an integrated approach to hazard analysis will result in effectively identifying site and facility hazards, including chemical hazards and the hazards associated with the disposal of the hazardous chemicals. Analysis can begin at these levels by assessing chemicals present in quantities greater than the threshold quantities (TQ) found in 29 CFR 1910.119 and 40 CFR 355. These materials are generally analyzed from the process safety perspective, i.e., potential for a catastrophic accident with immediate consequences. 

Hazard analysis is a continuous process performed prior to the time a chemical is requested for purchase through final disposal. Early integration of exposure and hazard assessment with work planning activities will help ensure that potential exposures associated with the work are addressed in the work plan. 

An operating hazard analysis and/or a job safety analysis should be performed to identify hazards associated with disposal operations. 

The analysis and control of hazards during the disposal phase should be addressed with an operating hazard analysis, a job safety analysis (a occupational and industrial safety tool), and/or change analysis. 

The final hazard analysis to be performed by the SSWG for this end product consists of a review of the disposal or decommissioning plan and a systematic effort to identify, analyze, and control hazards associated with terminating the life cycle for the end product. Techniques could include an OHA or job safety analysis. 

Step 3. Conducting a Hazard Analysis The actual plan begins by defining the problems that may require emergency responses. The problem definitions result from a hazard analysis and identifying hazardous materials that could affect the community. There are many sources for information about hazardous materials. Included are local companies, users of materials, transportation organizations and companies, and waste handlers and disposers. For each hazardous material, analysts must determine the hazards and quantities present or potentially present in the community. The planning team must know the potential distribution media (air, water, sod, vehicles, rad, etc.) and how each potentially impacts community s residents. 

In setting up a monitoring system, it is important that the purpose or the goal of the monitoring system be defined. It is also important that a Risk Assessment and a Hazard Analysis be performed on the disposal process. Agent monitoring is used during all phases on non-stoclq)ile operations to provide information that will help ensure the worker s safety. 

There is one that is sufficiently different that it should be treated separately— the facility hazard analysis. As the name implies, it focuses on hazards in a facility. The same hazard analysis procedure is used, but emphasizing facilities and the facility acquisition process. The purpose of the facility hazard analysis is to apply hazard analysis techniques to a facility and its operations for the entire facility life cycle—from concept through disposal. The facility is construed to mean actual buildings, the area around the buildings, and the operations into, out of, and inside the buildings. Specifically, it looks at items such as the following ... 

At the Taylor Road landfill (originally intended for the disposal of municipal refuse only), unknown quantities of hazardous wastes from industrial and residential sources were deposited. During the period when the landfill was active, soil and groundwater samples collected at the site were found to contain concentrations of volatile organic compounds and metals above acceptable safe drinking water standards. Analysis of samples collected from private drinking water wells indicated that contamination... 

The SSAHP developed by the Site G contractor did not indicate that the contractors routinely conducted job- or task-specific hazard analyses. In addition, the SSAHP did not specify that PPE selection for jobs and tasks must be based on the analysis of the health hazards associated with each job. Eurthermore, the SSAHP contained no procedures for objectively determining the effectiveness of decontamination of personnel or equipment. The decontamination program required incineration of all materials that could not be readily decontaminated such materials were placed in labeled disposal containers. The program, however, did...
