Venue Phi House, Southampton Science Park, Southampton


The loss of control of exothermic or gas generating chemical reactions, on plant scale, can have devastating primary and secondary consequences. Many industrial accidents graphically highlight the consequences – for example, those at Seveso, Bhopal and latterly at Jacksonville in Florida. Strategic assessment practices should be embedded to ensure that chemical reaction hazards are systematically identified early in process development and that the development process seeks to eliminate or reduce the risk potential. For the residual risk, plant operating procedures and controls should ensure that the residual risk is acceptably low and protection and prevention strategies are fully available and reliable in preventing harm. This interdisciplinary course aims to span the process lifecycle to provide an optimised protocol for assessing risks and prevention strategies at each stage. This course is designed to equip staff with the necessary tools to be able to identify chemical reaction hazards, interpret test data correctly and develop a robust basis of safety.


Day 1:

Delegates will learn to identify causes of hazard, understand the latest techniques for assessing risk and measuring and quantifying chemical process hazards. Developing inherently safer processes will be a focus along with outlining the strategic assessment process for reliable safe(r) process development. Numerous case studies will seek to embed the theories outlined. Methods for plant scale prevention and protection will also be introduced.

Day 2:

The provision of emergency relief systems for runaway chemical reactions and decompositions requires a detailed design approach that takes into account the dynamics of the uncontrolled reaction and the potential for multi-phase flow in the vent system. The DIERS (Design Institute for Emergency Relief Systems) methodology provides a practical framework for such studies, which is different to vent sizing for purely physical contingencies. This short course will examine the characterisation of runaway behaviour and the vent design approach. Data requirements, sizing equations and practical aspects will be discussed. Case studies and workshops are included.

PLEASE NOTE: Units can also be studied separately as single day courses, for more details on this please contact us via email or telephone.

A key aspect to our courses is for our delegates to gain the knowledge and solutions applicable to their own situations, so numbers are capped to ensure we have sufficient time for your feedback and early booking is therefore recommended.

Training will be held at our Southampton facility, with accommodation available at the Chilworth Manor Hotel, a 5 minute walk from Phi House.
