Hazards keeping track

Equations used to calculate percent yield or dilution ratios A list of disposable equipment (e.g., rubber gloves, Bunsen burners) Step-by-step instructions of the procedure Warnings to other scientists about unusual hazards Quantitative statements of reaction times and temperatures Descriptions of the physical appearances of synthesis products IR or NMR data confirming product purity Statistical packages used (including the name of the software) Reports of other software used to keep track of data (e.g., Excel)... 

It is again strongly recommended that distillation of methyl or ethyl azodicarboxylate be carried out from a thermally controlled bath, not an electrically heated mantle, for the latter may overheat the material being distilled. The bath should have a thermometer in it to keep track of the bath temperature, which should not be allowed to go higher than 130°C. The bath should be lowered at the end of the distillation. The distillation should be shielded on all sides by fixed shielding, as described in "Prudent Practices for Handling Hazardous Chemicals in Laboratories", National Academy Press, Washington, DC (1981), pp. 170-171 see also Org. Synth., Coll. Vol. VIin 993, p. vi. 

Except for the high-volume materials, most remaining chemicals are bought in relatively small quantities to meet specific needs of individual programs. Some chemicals pose unusual hazards, such as ethers that degrade over a short period of time. It is desirable to keep track of which group is ordering them and where they are to be formd. A central stores area would make a convenient distribution center for these special materials and would facilitate maintenance of records of their use. 

There has been a rapid growth in the data required for safety management. Today it is essential to keep track of many kinds of data. There is a need to capture incident and accident data. There is a need to track personal protective equipment issued to individuals. There is a need to link hazards and exposures to jobs and those in those positions. There is a need to track exposures of employees, training given or required for them, job assignments, and other factors. There is a need to track hazardous materials data. 

It may be important to keep track of fire extinguishers, hoses, hydrants, and other fire protection data. There is a need to track controls for hazards put in place. There is a need to track product ownership, recalls, repairs and modifications. 

Estimate the source term (source term modeling), i.e., how much material in what form (gas/liquid/two-phase) is being released from containment as a function of time, and develop the release scenarios or possible hazard outcomes (toxic cloud, fire, explosion, etc.) following the release. (A powerful tool to develop and keep track of possible outcomes following a release is an event tree event trees are commonly used in quantifying the frequency of these various outcomes and were therefore described in Section 10.2.8.)... 

Employee satisfaction is investigated once every 2 years. Development conversations with employees were implemented a couple of years ago and are still in progress. No agreed upon system of rewards has been adopted but the top management has a bonus system and workers are offered a free lunch for every hazardous near miss case they report. The facilities are functional and clean enough. As usual in the crane business, the equipment is specific and functional and back-up machinery exists. Keeping track of equipment such as spare parts is not a problem. Customer feedback is collected Ifom each site and reviewed in monthly meetings. Feedback on customer satisfaction is performed after projects. 

The PtD team can help ensure the right people are pulled together and the project team is led through identification and evaluation of potential hazards. Once hazards are identified, ask the individuals on the team to develop controls and abatement methods. As this is done, the PtD team should keep track of challenges, as well as the aspects that work well. 

Materials which can deteriorate, become unstable, lose potency, or degrade into hazardous compoimds must be clearly marked. The responsible manager must keep track of these materials and take appropriate action to dispose of or replace them. Nonhazardous deterioration of materials can be dealt wifir in a conventional manner. The formation of hazardous materials demands extra attention and due care. 

As with any team effort, the quality of the leadership is critical. The leader must somehow allow people to dream up potentially bizarre situations in anticipation that one or two of these situations will actually turn out to be plausible. At the same time, he or she has to keep the hazards analysis on track in terms of schedule and budget. Also, some team members enjoy the brainstorming process so much that they become counterproductive in terms of overall team effort. The leader needs to keep them focused. 

Beyond solid wastes, a chemical substance may be labeled as a "hazardous waste" under RCRA if it is listed as a hazardous waste by EPA or if it is determined to be a characteristic "hazardous waste" that exhibits high ignitability, corrosivity, reactivity, or toxicity. Once a material is labeled as a hazardous waste, the material is tracked and permitted at all stages of the manufacturing, use, and disposal process. Generators of hazardous wastes are required to keep detailed records from cradle to grave of the substance to ensure unintended releases and environmental contamination do not... 

The purpose of the manifesting system is to establish accountability for and tracking of hazardous waste shipments. The manifest is an important feature of RCRA s "cradle to grave" system. A generator must keep a copy of each manifest for three years. The generator must also maintain records and report hazardous waste management activity, including the amount of hazardous waste produced, the transporters of the wastes, and the TSDFs in possession of the hazardous waste (40 CFR 262.40-262.44).
