Inherent Safety Review Training

Experience has shown that reactive chemistry hazards are sometimes undetected during bench scale and pilot plant development of new products and processes. Reactive chemistry hazards must be identified so they can be addressed in the inherent safety review process. Chemists should be encouraged and trained to explore reactive chemistry of off-normal operations. Simple reactive chemicals screening tools, such as the interactions matrix described in Section 4.2, can be used by R D chemists. 

Low hazard process reviews can be completed in several hours. Reviews of complex projects are normally completed in one to two days. The key to an effective and efficient review is good preparation. 

If an organization chooses to include inherent safety reviews in its implementation approach, training should be included on how to conduct an inherent safety review. 

Inherent Safety Review Methods and Available Training 

Companies may wish to develop workshops to train potential team members in the inherent safety review process. The workshop can provide background information on inherent safety concepts, the extensive systems required to manage hazardous materials, and information on the inherent safety review process. Videos, problems, examples, and team exercises can be included to enliven the education process.

The five levels of defence in depth are covered in the present review. For given objectives at each level of defence, a set of challenges is identified, and several root mechanisms leading to the challenges are specified. Finally, to the extent possible, a comprehensive list of safety provisions, which contribute to preventing these mechanisms from occurring, is provided. A broad spectrum of provisions, which encompass the inherent safety features, equipment, procedures, staff availabiUty, staff training and safety culture aspects, is considered.
