Chemical reactivity hazard types

During the development of a new facility or process, or when introducing a new process into an existing facility for the first time, an inherent safety review can be conducted to understand the chemical reactivity hazards and explore hazard reduction alternatives. The review need not be limited to chemical reactivity hazards. It can be used to address all other types of process hazards at the same time, including flammability/ combustibility dust or mist explosibility elevated or reduced pressures or temperatures phase differences and health hazards such as toxicity, corrosivity, and asphyxiation.

If the answer to Question 6 is YES, then you should make use of the information in Chapter 4, because a chemical reactivity hazard may be present. The information in Chapter 4 should be sufficient to identify chemical reactivity hazards that must be managed. In addition, if hazards are identified, the essential practices presented in Chapter 4 should be sufficient to manage these types of chemical reactivity hazards. [Pg.52]

The systematic search for all chemical reactivity hazards, beyond the information gained from the sources listed in Section 4.2, should begin with a literature survey of the chemicals to be used and the type of processing, if any, that will be employed. The literature survey might turn up quantitative hazard data or previous incidents. Other information that will be useful later, such as standard practices or model prevention programs, may also be uncovered. [Pg.88]

A useful indication of a chemical reactivity hazard is the heat (energy) of reaction. For some reaction types, the heat of reaction may be known by another name, such as heat of decomposition, heat of combustion or heat of polymerization. [Pg.89]

Time and resources need to be made available to assess the safety significance of proposed changes when dealing with chemical reactivity hazards. The effects of proposed changes need to be carefully reviewed, new test data may need to be obtained, and experts may need to be consulted. This issue is especially challenging in some types of facilities such as specialty chemical operations, where many different products and processes are introduced on a regular basis. [Pg.126]

Checklists. A checklist is simply a detailed Hst of safety considerations. The purpose of this Hst is to provide a reminder to safety issues such as chemical reactivity, fire and explosion hazards, toxicity, and so forth. This type of checklist is used to determine hazards, and differs from a procedure checklist which is used to ensure that the correct procedure is followed. [Pg.470]

The scope of this book includes several aspects of safe process design and operation, such as the choice of reactor type, safe operating conditions, and the selection of protective systems, primarily related to chemical reactivity. However, even in a process plant where these aspects have been carefully considered and thoroughly applied, there are still numerous events that can occur and can lead to hazardous incidents. Examples of such events are ... [Pg.175]
