Hazard control anticipation

The main body of the report should provide a narrative concentrating on the key findings of the analysis with any recommended hazard control solutions. Usually, a calendar schedule showing anticipated dates of subsequent, future O SHAs is included in the report along with the completed O SHA worksheets (Stephenson 1991).

When developing a hazard control program, you should anticipate resistance when teaching new job practices and procedures to employees. 

The Scope and Functions of the Professional Safety Position issued by the American Society of Safety Engineers (1998) says that the s ety professional is to anticipate, identify, and evaluate hazardous conditions and practices and develop hazard control designs, methods, procedures, and programs. Those are valid statements. 

Note that according to the first bulleted item, the safety professional is to anticipate hazards. And the second bulleted item indicates that safety professionals are to develop hazard control designs. ... 

Industrial Hygiene Reviews These reviews evaluate the potential of a process to cause harm to the health of people. It is the science of the anticipation, recognition, evaluation, and control of health hazards in the environment. It usually deals with chronic, not acute, releases and is involved with toxicity. 

Work zones are designed to control access to actual and anticipated hazards. Work zone positioning is based on hazard characterization and exposure assessment. Anticipated work activity, potential releases, and the amount of contaminant dispersion are important for delineating these zones [3]. 

Introduction Chemical reactivity is the tendency of substances to undergo chemical change. A chemical reactivity hazard is a situation with the potential for an uncontrolled chemical reaction that can result directly or indirectly in serious harm to people, property, or the environment. A chemical reaction can get out of control whenever the reaction environment is not able to safely absorb the energy and products released by the reaction. The possibility of such situations should be anticipated not only in the reaction step of chemical processes but also in storage, mixing, physical processing, purification, waste treatment, environmental control systems, and any other areas where reactive materials are handled or reactive interactions are possible. 

Detonation arresters are typically used in conjunction with other measures to decrease the risk of flame propagation. For example, in vapor control systems the vapor is often enriched, diluted, or inerted, with appropriate instrumentation and control [5]. In cases where ignition sources are present or predictable (such as most vapor destruct systems), the detonation arrester is used as a last-resort method anticipating possible failure of vapor composition control. Where vent collection systems have several vapor/oxidant sources, stream compositions can be highly variable and this can be additionally complicated when upset conditions are considered. It is often cost-effective to perform hazard analyses such as HAZOP or fault... 

A CERCLA response or liability will be triggered by an actual release or the threat of a hazardous substance or pollutant or contaminant being released into the environment. A hazardous substance [CERCLA 101(14)] is any substance requiring special consideration due to its toxic nature under the Clean Air Act, Clean Water Act, or Toxic Substances Control Act (TSCA) and as defined under the RCRA. Additionally [CERCLA 101(33)], a pollutant or contaminant can be any other substance not necessarily designated or listed that will or may reasonably be anticipated to cause any adverse effect in organisms and/or their offspring. 

A risk-based waste classification system would be established by focusing on risks that arise from disposal of hazardous wastes. Thus, the amounts of hazardous chemical wastes that would be acceptable for near-surface disposal over the longer term would need to be evaluated. While NCRP believes that many hazardous chemical wastes would continue to be acceptable for near-surface disposal, it should be anticipated that this will not be the case for some wastes that contain high concentrations of heavy metals e.g., see Okrent and Xing (1993). As a result, some hazardous chemical wastes could be classified as high-hazard (see next section), and such a classification also could also mean that perpetual institutional control will be required at some existing burial sites. 

However, emission control dust or sludge from ferrochromium and ferrochromium-silicon production is listed as hazardous waste by EPA (1988b). The processed wastes from several chromium chemical industries are designated as hazardous wastes as well (EPA 1981), and disposal of process wastes is regulated by the EPA. Land filling appears to be the most important method for the disposal of chromium wastes generated by chemical industries. Of the total chromium released in the environment by chemical industries, 82.3% is released on land. An equally large amount of chromium waste is transferred off-site (see Section 5.2). It is anticipated that most of this off-site waste will be disposed of in landfills after proper treatment. It is important to convert chromium wastes into forms of chromium... 

E.xplosions can be prevented or controlled. Tlie release of energy is so rapid that the usual concepts of e.xtinguislnncnt are practically impossible to apply. It is essential during the risk evaluation procedure to identify tliose processes, operations and plant areas wliicli arc c.xposed to explosion liazards. Anticipating the t> pc and degree of hazard well in advance is essential if tlie proper e.xplosion pret ention steps are to be taken. 

Since Ehrlich s time there has been continual progress in the de velopment of new chemotherarpeutic agents. Fifteen years ago the infectious diseases constituted the principal cause of death now most of these diseases are under effective control by chemotherapeutic agents, some of which have been synthesized in the laboratory and some of which have been isolated from micro-organisms. At the present time only a fetv of the infectious diseases, especially certain viral diseases, such as poliomyelitis, constitute major hazards to the health of man, and we may confidently anticipate that the control of these diseases by chemotherapeutic agents will be achieved in a few years. 

Hundreds of chemicals are regulated under CERCLA they are classified as (i) hazardous substances and (ii) pollutants or contaminants. The definition of a hazardous substance under CERCLA is broad and is based on other environmental regulations. A CERCLA hazardous substance does not need to be a waste or waste material. It can be a commercial chemical, formulation, or product. A CERCLA hazardous substance is defined as any chemical regulated under the Clean Water Act, the Clean Air Act, the Toxic Substances Control Act (TSCA), or the Resource Conservation and Recovery Act (RCRA). However, two materials that are excluded from the hazardous substances list are petroleum and natural gas. A CERCLA pollutant or contaminant is defined as any other chemical or substance that will or may reasonably be anticipated to cause harmful effects to human or...
