Major hazards inventories

The results of the Flixborough investigation made it clear that the large inventory of flammable material in the process plant contributed to the scale of the disaster. It was concluded that limitations of inventory should be taken as specific design objectives in major hazard installations. It should be noted, however, that reduction of inventoiy may require more frequent and smaller shipments and improved management.

This accident resulted in significant changes in England and the rest of the world in the manner in which chemical process safety is managed by industry and government. One of the conclusions reached as a result of this accident, which has had a wide effect in the chemical industry, is that limitations of inventory (or flammable materials) should be taken as specific design objectives in major hazard installations. ... 

High inventories of stored pressure energy eonstitute a major aeeident hazard. 

Raw material and in-process storage tanks and pipelines often represent a major portion of the risk of a chemical plant. Attention to the design of storage and transfer equipment can reduce hazardous material inventory. 

In fact, regulatory drivers are often seen as instrumental in spurring innovation. An assessment by a major aerospace manufacturer of what drives innovation towards safer processes for hazardous waste streams revealed that The regulatory drivers for waste reduction are familiar to most by now, and may be summarised into three categories of legislation 1) inventory reporting, 2) emission reporting, and 3) employee exposure levels. Anticipation of future restrictions was a decisive factor in this project. ... 

Major elements of a CHP plan include listing of responsibilities for employers, employees, and a chemical hygiene officer. Also among the items that have to be covered in the plan is the stipulation that every laboratory must have a complete chemical inventory that is updated annually. A copy of the Material Safety Data Sheet (MSDS), which defines each chemical as toxic, carcinogenic, or dangerous, must be on file and readily accessible and available to aU employees 24 hours a day, 7 days a week. The MSDS contains important information for the benefit of laboratory employees. The chemical manufacturer s information as supplied on the MSDS is used to ascertain whether a certain chemical is hazardous. Each MSDS must give the product s... 

In the early days of microchannel development, the key selling point involved non-reactive applications, in particular heat transfer [1-12]. Work in this area quickly demonstrated that microchannel components could provide rapid heat transfer while maintaining low pressure drop, despite the use of very narrow process channels [1, 2], From there, microchannel research expanded to a range of non-reactive- and reactive-applications, where the major advantages of this technology not only included rapid heat and mass transfer but also the precise control of process conditions, low inventory of hazardous reactants, use of surface phenomena to significant advantage, and overall process intensification [13],... 

Additionally, under the Europa Environmental Directive 96/82/EC called Saveso II Directive" on the control of major accident hazard involving dangerous substances, information on dangerous substances is inventoried. Of the several interesting literature databases, a process chemist would find the literature references from www.rxeforum.com very useful for the kinetic models and calorimetric data for product development and validation very useful while considering the thermal stability of the reactions. The article The Identification of Decomposition Products in as Industrial Nitration Process under Thermal Runaway Conditions " would have been very useful in developing the direct nitration process. 

ColorMatrix Europe supply additive and colorant masterbatch for use in the manufacture of polymeric materials and articles intended for various applications such as food contact packaging, and toys. ColorMatrix Europe products may be manufactured at different manufacturing locations (USA, Europe, and Asia). The Global regulatory department based within Europe keeps an inventory of raw materials used across all global locations and manages supplier information, chemistry information and so on. ColorMatrix Europe s global inventory contains hundreds of raw materials however the majority of these are classified as non hazardous. 

The regulation defines the major objective of PSM of highly hazardous chemicals as the prevention of unwanted releases, especially into locations where people would be exposed to serious hazards. There is a need for a systematic approach to evaluating the whole process. The introduction specifically mentions reduced inventories as one approach to control.
