Hazard identification handling

An elementary introduction to chemistry is given in Chapter 3 this serves only to provide background and for more advanced consideration reference will be necessary to specific text books, e.g. as listed in the Bibliography. A brief discussion of the relevance of physicochemical principles to hazard identification is given in Chapter 4. Relevant toxic and flammable properties, and summaries of appropriate precautions to cater for them during handling, use and disposal, are provided in Chapters 5 and 6, respectively. Reactive hazards are discussed in Chapter 7. The special problems with cryogenic materials and chemicals under pressure, typified by compressed... 

A number of hazard identification and analysis techniques (e.g., HAZOP), can be applied to identify, analyze, and reduce and/or mitigate the process hazards, which includes handling of reactive chemicals and energetic reactions. Chapter 4 provides an overview of these kinds of techniques as related to reactive chemicals mote detailed reviews of hazards analysis techniques are included in [2,3]. 

A program is necessary for identifying all materials in the workplace, and making employees aware of the hazards of these materials and the necessary precautions to be taken to prevent or control personnel exposure. Materials Hazard Identification and information gathering is an essential element of fire prevention. The hazardous properties of all chemical substances used in the workplace should be known in order to develop the appropriate design, routine handling practices, and fire prevention plan. 

Although use of isolators or other effective engineering controls is the preferred method of handling highly potent compounds in solid form, this is not the only possible approach. We have found that use of traditional laboratory controls and a combination of high level of PPE in conjunction with rigorous administrative controls can provide adequate protection. Before considering the use of any of these solutions in a workplace, make sure workers are fully informed about hazard identification, risk assessment and control options.

A separate chapter addresses the problems related to handling dust explosible substances. This is followed by a short description of the main hazard identification methods. 

The task analysis technique has been developed mainly to handle human factors (in HAZID and other methods). In HAZID this is helpful in addressing human factors such as human error, man—machine interface, and procedural error. Of the various hazard identification techniques, task analysis is one of the most important. The other techniques are discussed in subsequent chapters, but here discussions will be on task analysis. Task analysis is the study of what users need to do, in terms of actions and/or cognitive processes, to achieve a task objective. There are several factors, such as task duration, repetitive frequency, task allocation, complexity, equipment, ambience, and environmental conditions, which are required for the task and they very much influence the performance. At times, tasks are often used interchangeably with process.

Section 2 Hazards Identification This section in the SDS in Appendix A is especially helpful when trying to understand hazards and relative risks from handling a chemical. CHS ratings, pictograms, and signal words provide useful information about the hazards of the chemical. 

The required information must be given under sixteen specific headings covering identification of the chemical product and its supplier composition information, hazard identification, first aid measures, handling and storage, exposure control and personal protection, physical and chemical properties, stability and reactivity, toxicological information, ecotoxicological information, disposal, transport require-...

This is a brief summary of NFPA 704 which addresses hazards that maybe caused by shoii-term, acute exposure to a material during handling under conditions of fire, spill, or similar emergencies. This standard provides a simple, easily recognized, easily understood system of markings. The objective is to provide on-the-spot identification of hazardous materials.
