This webinar, hosted by the CIA, will be presented by Elaine Skilling - HM Principal Specialist Inspector (Human Factors Engineering) of the CEMHD division of the HSE. It follows the well-attended webinar held in July 2025 on HF for COMAH sites. This time Elaine will discuss the topic of ‘COMAH Critical Communications’ from the HSE’s Human Factors COMAH Delivery Guide. The webinar is aimed primarily at those operating COMAH sites but may also be of interest to non-COMAH operators. The topics covered will include shift handovers and permit to work systems. For those registered for the event, there will be the opportunity to submit questions on these topics ahead of the event, which Elaine will address in her presentation. Further details here.
