Hazards effects Safety

Has an effective safety and health program (for example, safety procedures, training, hazard identification and analysis) been established to protect personnel on the work site, including employees and contractors If no, explain. 

The information to be compiled about the chemicals, including process intermediates, needs to be comprehensive enough for an accurate assessment of the fire and explosion characteristics, reactivity hazards, the safety and health hazards to workers, and the corrosion and erosion effects on the process equipment and monitoring tools. Current material safety data sheet (MSDS) information can be used to help meet this requirement but must be supplemented with process chemistry information, including runaway reaction and over-pressure hazards, if applicable. 

The UL plastics program is divided into two phases. The first develops information on a material s long- and short-term properties. The second phase uses these data to screen out and indicate a material s strong and weak characteristics. For example, manufacturers and safety engineers can analyze the possible hazardous effects of potentially weak characteristics, using UL standard 746C. 

Clearly the elimination of hazards is the most effective safety measure and often the least... 

The Dow and Mond Indexes provide a relative ranking of the hazards and risks in a chemical process plant. This is accomplished by assigning penalties and credits based on plant features such as the presence of hazardous materials and the safety devices which can mitigate any hazardous effects. Penalties and credits are then combined into a single hazard index for the process unit in question. 

The HF tester is a commercial safety tool for sensing whether an unidentified liquid contains HF [2], It shows in an exemplary way how the electrochemical properties of a silicon electrode, namely its I-V curve in HF, can be applied for sensing. The ability to dissolve an anodic oxide layer formed on silicon electrodes in aqueous electrolytes under anodic bias is a unique property of HF. HF is therefore the only electrolyte in which considerable, steady-state anodic currents are observed, as shown schematically in Fig. 3.1. This effect has been exploited to realize a simple but effective safety sensor, which allows us to check within seconds if a liquid contains HF. This is useful for safety applications, because HF constitutes a major health hazard in semiconductor manufacturing, as discussed in Section 1.2.

The risk characterization is carried out by quantitatively comparing the outcome of the hazard (effects assessment) to the outcome of the exposure assessment, i.e., a comparison of the NOAEL, or LOAEL, and the exposure estimate. The ratio resulting from this comparison is called the Margin of Safety (MOS) (MOS = N(L)OAEL/Exposure). This is done separately for each potentially exposed population, i.e., workers, consumers, and man exposed via the environment, and for each toxicological endpoint, i.e., acute toxicity, irritation and corrosion, sensitization, repeated dose toxicity, mutagenicity, carcinogenicity, and toxicity to reproduction. 

Guidance to date supports the risk assessment principles for general chemical substances already published by the Commission (1996). Consequently, the risk characterisation simply involves a quantitative comparison of the outcome of the hazard/effects assessment with the exposure assessment. For human risk this involves the calculation of the TER (Toxicity Exposure Ratio) and comparing it with the MOS (Margin Of Safety). For environmental risk the PEC/PNEC ratio (Predicted Environmental Concentration versus the Predicted No-Effect Concentration) for the various environmental compartments. 

This safety audit is used for identifying inputs and material flows, processes and intermediates, and final products - but with special attention paid to human-material/process/equipment interactions that could result in (a) sudden and accidental releases/spills, (b) mechanical failure-based injuries, and (c) physical injuries - cuts, abrasions, and so on, as well as ergonomic hazards. Additional sources of adverse effects/safety problem areas are records/ knowledge of in-plant accidents/near misses, equipment failures, customer complaints, inadequate secondary prevention/safety procedures and equipment (including components that can be rendered non-operable upon unanticipated events), and inadequacies in suppliers of material and equipment or maintenance services. 

Another subject of scientific debate is still the bioavailability and toxicity of bound residues (2). Data on this particular topic are sparse but tend to suggest the absence of hazardous effects of bound residues rather than the contrary. Answers that remain to be provided on this subject concern the relevance of these toxicological effects and, if the effects are viable, the best and most reliable method by which they can be measured and evaluated for a specific compound. As long as these questions are not answered satisfactorily, any attempt to address them can only be considered as a shot in the dark and a potential waste of finance and time. The industry is prepared to perform any additional safety evaluation as long as the answers are reasonable and can result in a greater guarantee of protection for the consumer. 

A complete list of paint and ink pigments, their chemical compositions, and their hazardous effects, is found in Artists Beware and The Artist s Complete Health and Safety Guide (see References at the end of this chapter). 

Identifying the potential hazards (PHA, process hazard analysis, or HAZOP, hazard and operability analysis) during operation must be done from a wide-angle approach dangerous situations can occur due to many root-cause situations other than those specified by, for instance, ASME or PED. Based on the results of the risk assessment, the pressure equipment can be correctly designed and the most effective safety system selected. 

Specify the toxic or nontoxic character of the main chemicals involved in the process. Information on toxicity and hazard effects can be found on the websites of agencies for public environment and health, such as for example the US Environmental Protection Agency (EPA) and the European Environmental Agency. A good introduction to environmental engineering is the book of Allen and Shon-nard [4]. In the field of process safety, the book of Crowl and Louvar [5] is still popular. The book of Kletz [6] covers the topics of hazard and operability, as well as hazard analysis.

Companies which handle hazardous chemicals operate in a complex regulatory environment, often subject to many regulations, standards, rules, and procedures from government, standards organizations, and insurers. These requirements can be confusing, redundant or even mutually inconsistent. Moreover, even complete regulatory compliance will not assure a safe warehouse operation. The unique operation of every company therefore requires that management should look beyond the letter of the law to the specific needs of that operation to establish an effective safety policy that is based on the nature of the hazards involved. 

Do not expect a label to deliver more than it can. Extensive information, hazard warnings, safety information, imagery, use instructions, etc. cannot effectively be squeezed into a small label. If a small label is all that s possible, then perceptual elements must predominate— size and variety of print, color and color contrast, isolation and emphasis of hazard and warning areas, layout factors. At the very least, the label must communicate the product name, what it does, legally required warnings, and necessary use information rapidly and with minimal difficulty. 

In this case, even trace levels of contamination could have a hazardous effect on the quality and safety of the excipient. 

One key to having a cost-effective safety effort is to embed it into a system engineering process from the very beginning and to design safety into the system as the design decisions are made. Once again, the process starts with the fundamental activities in chapter 7. After the hazards and system-level safety requirements and constraints have been identified the design process starts ... 

Some properties of effective training programs are presented in chapter 12. Everyone involved in controlling a potentially dangerous process needs to have safety training, not just the low-level controllers or operators. The training must include not only information about the hazards and safety constraints to be...
