Highly hazardous substance

Is there potential that the product may result m the environmental or non-workplace release of a highly hazardous substance or an environmentally difficult material If yes did the toller receive a life cycle evaluation (for example, disposal of products, handling returns and rejects) Does the Toller understand the information Was written acknowledgment obtained indicating that the information was received ... 

Numbers 7 and 8 in Table 3.6 represent high hazard substances such as azides, peroxides, perchlorates, and nitro compounds. The handling of such materials requires extreme care and safety precautions. 

For substances Give up the use of highly hazardous substances Make substances safe by dilution, etc. 

Risk assessment therefore reqnires knowledge of both the hazard of a chemical and the purpose for which it is being used. A highly hazardous substance presents a very low risk if it is securely contained with no likely exposure. Conversely, a substance of relatively low hazard may present nnacceptable risks if extensive exposnre can occur. Both hazard and exposure must be considered before the risk can be adequately assessed.

Nitric oxide was approved by the FDA in 1999 for use as a vasodilator in the treatment of hypoxic respiratory failure in full- and near-term infants. It is a colorless and essentially odorless gas with a very narrow therapeutic window for patients. Acute exposure effects include mucous membrane irritation and drowsiness. More serious effects include delayed pulmonary toxicity and damage to the central nervous system effects. Exposed employees may seem relatively asymptomatic at the time of exposure. It can take as long as 72 hours to manifest clinical symptoms. OSHA classifies nitric oxide as a highly hazardous substance. 

Have formal process hazard analyses (PHAs) been completed for highly hazardous processes (for example, those processes involving toxic or volatile substances, highly toxic materials, severe lachrymators, flammables, explosive compounds or potential runaway reactions) If yes, please summarize status of each. 

Catastrophic release Under OS HA PSM and EPA RMP, it means a major uncontrolled emission, fire, or explosion, involving one or more highly hazardous chemical substances (per OSHA) or regulated substances (per EPA) that presents serious danger to employees in the workplace (per OSHA) or imminent and substantial endangerment to public health and the environment (per EPA). 

The transportation of chemicals is dierefore highly regulated. In addition to general transport legislation numerous statutory provisions govern die carriage of hazardous substances by air, road, rail and sea. These tend to address die need for ...

In the immediate term, however, your plan may be most effective if you focus on the specific needs and priorities you have identified in the course of your work so far. If you clearly define the scope of your plan, and it directly addresses specific needs, your efforts will be far more successful than if you try to do all things for all people. Moreover, focusing on priority needs will almost certainly provide a sound basis for expansion or adaptation for example, procedures developed to address training for operators using high-hazaid materials at one facility (see Rextown vs. Effingham in Figure 5-2) should be readily adaptable to lower-hazard substances at another facility— far more so than the other way around. 

This is a situation where a plant appears to be operating successfully, without a major human error problem. However, management are interested in assessing the systems in the plant from the point of view of minimizing the error potential. This type of exercise is particularly relevant for plants dealing with substances or processes with high hazard potential, for example, in terms of... 

We now illustrate the opposite case where the intermediate is in fact a highly undesirable substance, as it presents a health, or even explosion, hazard. The hydrogenation of aromatic nitro compounds, such as the one shown in Fig. 2.6, is industrially important for the production of dyes, whiteners, agrochemicals and pharmaceuticals. The reaction occurs in the presence of a platinum catalyst and proceeds via intermediates, among which the hydroxylamine (-NHOH) species is particularly hazardous, as it is both carcinogenic and explosive. Unfortunately, standard platinum catalysts give rise to high levels of this undesired intermediate. 

Stripping of electrical and electronic waste appliances must be carried out properly. During the processing of waste appliances (e.g., in shredders), it is essential to avoid that components highly contaminated with hazardous substances end up in fractions that are intended for recycling. It is furthermore necessary to ensure that the disposal of treatment residues (e.g., shredder residues) is not impeded by the presence of hazardous substances. As a rule, components containing particularly hazardous substances are to be removed manually. Future disposal processes, such as pyrolysis, may allow recycling of appliances without prior removal of hazardous substances, in which case it will be possible to do without the disassembly of hazardous components.411...
