VENTILATION

clearer with a visual demonstration. Closing out the Part A section are the design requirements of operating theatre control panels, and how they should be validated and assessed.


HTM 03-01: Part B: Operational Management We assess the legal requirements of HTM 03-01: Part B, and the operational management of critical ventilation systems. We also assess areas not covered by HTM 03-01, such as the CIBSE Lighting Design guide LG2: Lighting for healthcare premises (2019), a critical area of engineering requirements in spaces such as operating theatres. Part B ties responsibilities back to HTM 00, and covers areas of testing that AP(V) engineers may not be exposed to, such as microbiological testing and how it is carried out.


Capital installations and live demonstrations During the day there is also a session delivered by Howorth Air Technology’s Group Sales director, Tom Ford. During it, he shares his extensive experience of designing operating theatres to be ergonomically satisfactory for the requirements of the Operating department practitioner team. It is not untypical for equipment to be


installed without considering important factors such as air flow and patient positioning. We highlight the importance of working with contractors and architects to consider the location of critical equipment such as a fixed CT scanner, medical gas pendants, and monitoring arms. During his part of the workshop, Tom Ford also looks at future-proofing in line with ‘intelligent engineering’, remote monitoring, and continuous innovation. Once the presentations have been

delivered, delegates move on to practical demonstrations in our fully functional, HTM 03-compliant, UCV operating theatre. Demonstrations are led by our technical team leaders, and cover the three UCV tests: filter testing (both DOP & DPC), downflow grid testing, and a non- entrainment demonstration. We use smoke visualisations to illustrate


the movement of air in an operating theatre, and how individual items of equipment in the theatre interact with one another – for example how open door protection works, and the differences between the ‘prep’ area of the OR and the theatre itself, and how that impacts UCV considerations. We also assess how different types of operating lights have an impact on airflow.


Cementing relationships Howorth Air Technology has now delivered the CPD-accredited sessions to over 150 healthcare professionals, including Operating department practitioners, infection control specialists, Chartered Mechanical Designers, estates management personnel, apprentices, and entry-level engineers. We have had some great feedback, and we will continue to develop the sessions to ensure that healthcare providers understand the complex and specialist air ventilation equipment that they commission, design, and install. We have a firm belief that knowledge-sharing will eventually result in a higher calibre of product for the NHS and healthcare sector, with less downtime, happier environments, and a sustainable future.

Mike Dunne, Service and Aftersales Technical manager, joined Howorth Air Technology in 2009 as an electrical engineer in the company’s Production team. Early in his career he became a Medical Commissioning engineer, delivering over 300 UCV systems across three continents. After several years in the role, he became Medical Commissioning Team leader, supporting both the Capital and Aftersales teams on compliance issues and integration of BMS systems in line with HTM 03. He subsequently became Howorth’s Technical manager, working directly with Service and Aftersales director, Claire Fenlon, to expand the business’s Service and Aftersales capabilities. He has continued to progress his professional development, completing an HNC in Electrical and Electronic Engineering, an ILM Level 5 Diploma in Leadership and Management, and gaining P601 and P602 (in relation to LEV Systems), NEBOSH, and IOSH qualifications. He is in his final year of a BEng (Hons) degree in Building Services and Sustainable Engineering at the University of Central Lancashire, where his dissertation focuses on how the UK healthcare sector can reduce consumption to support the NHS’s Net Zero goals.


As Howorth’s Technical manager, he has compiled and delivered CPD sessions, is responsible for assessing the performance of the Engineering team and ensuring any skill gaps are adequately filled, and acts as the main technical contact for many UK hospitals. He represented Howorth Air Technology on the Working Task Group for the collation of HTM 03-01 (2021). He is registered with the Engineering Council, is a Technical Member of the Institute of Engineering and Technology, and is a member both of IHEEM, and of the Institute of Local Exhaust Ventilation Engineers via CIBSE.
