On 15th November 2015, there was an uncontrolled release of around 15 tonnes of LPG through a valve near to the main roadway used by LPG road tankers visiting Esso Petroleum Company’s refinery in Fawley, Hampshire.
The leak went undetected for around four hours before being discovered by an employee on his way home. It took a further hour to establish the source of the leak, with on-site emergency personnel having to enter the area to reset the valve.
An investigation by the HSE found that the leak occurred because LPG was put through the pipe work at too a high a pressure for the valve. There was no process in place to detect the discrepancy in the flow in the pipe and the company had failed to take all measures necessary to prevent a major incident.
Esso Petroleum Company Limited pleaded guilty to breaching Regulation 5(1) of The Control of Major Accident Hazards Regulations (COMAH) 2015 and was fined £500,000.
Speaking after the hearing, HSE inspector, Jonathan Halewood said: “The measures required to prevent incidents should be proportionate to the risks. Where companies handle large quantities of substances that can cause major incidents, such as LPG, they are required to have layers of protection in place to prevent incidents.
“In this incident, a number of those layers either failed or were not in place resulting in a significant leak. Even though there was no fire or injury on this occasion, there was potential for a major incident. The prosecution has been brought to highlight the importance of maintaining the layers of protection and preventing this kind of major leak.”

What you’ll get: The Committee has since reported on Government failures in balancing risk across many aspects of its response to the pandemic, and lack of planning and preparedness despite an influenza pandemic having been identified as the UK’s top non-malicious risk on government’s National Risk Register since 2008.
This follow up inquiry is based on the NAO’s recent findings that Government was not fully prepared for the wide-ranging impacts of the COVID-19 pandemic on society, the economy and essential public services, and did not act upon some warnings from the simulations carried out prior to COVID-19, which highlighted issues around planning, coordination and capability that apply to pandemics more broadly.
For example, PAC says that the Government lacked detailed plans on shielding, employment support schemes and managing the disruption to schooling. Departments’ pandemic plans and business continuity plans set out some, but not all, of the responses required to maintain operations during the pandemic.
Preparations for EU exit enhanced the crisis capabilities and risk planning of some departments but meant that government paused work on other emergency preparations, limiting its ability to focus on other risk and contingency planning at the same time.
During this inquiry, the Committee will question senior officials at DHSC and the Cabinet Office. The inquiry is currently accepting evidence. The Committee is inviting views, and welcome submissions from anyone with answers to the questions in the call for evidence. Evidence may be submitted until 5 January 2022.

The employee of Bakkavor Fresh Cook Ltd was crushed in the machine after its safety systems were over-ridden and the machine worked on whilst it was live. It should have been isolated before work on it began.
Investigating, the HSE found that the task was carried out by the employees in this fashion on a regular basis and that the company should have been aware. No risk assessment of the task had been completed and employees had not been provided with a safe system of work to carry it out. The lack of a safe system of work for the task and the company’s failure to monitor how the work was done, led employees to devise their own way of conducting the procedure which included over-riding the safety systems and using unsafe working practices.
Bakkavor Fresh Cook Ltd of Sluice Road, Holbeach St Marks Spalding, pleaded guilty of one breach of Section 2(1) of the Health and Safety at Work etc. Act 1974 and were fined £130,000 and ordered to pay costs of £2607.10.
At the end of the trial HSE inspector Tim Nicholson commented: “Those in control of work have a responsibility to devise safe methods of working and to provide the necessary information, instruction and training to their workers. If a suitable safe system of work had been in place prior to this incident, alongside good monitoring of the way the work was done, the injuries sustained by the employee could have been prevented.”

What you’ll get: The model – developed by researchers at Imperial College London, the University of Cambridge and University of Leeds, and jointly funded by the PROTECT COVID-19 National Core Study and UK Research and Innovation – uses monitored CO2 and occupancy data to predict how many workers are likely to be infected by an asymptomatic but infectious colleague.
High indoor CO2 levels are related to lower ventilation rates and high occupancy, so monitoring them can provide an important red flag to building managers to identify areas of inadequate ventilation. This can help assess the risk of airborne transmission of the COVID-19 virus. Achievable interventions can then be made, for instance, to improve ventilation or change worker attendance patterns to reduce occupancy.
While applications of the infection model so far have demonstrated that most workers in well ventilated open plan offices are unlikely to infect each other via airborne particles, the risk becomes greater if the space is poorly ventilated or if the workers are involved in activities which require more speaking. For instance, the model predicts each infected person could infect two to four others in an adequately ventilated but noisy call centre. Risks are also likely to increase if the infected individual is a ‘super spreader’.
Dr Henry Burridge, Senior Lecturer in Fluid Mechanics at Imperial College London and lead author of the paper, said: “In shared spaces such as offices and classrooms, exposure to infectious airborne matter builds up over time, during which room occupancy may vary. By using carbon dioxide levels as a proxy for exhaled breath, our new model can assess the variable exposure risk as people come and go.
“Our work emphasises the importance of good ventilation in workplaces and in schools. The model demonstrates that by managing the ventilation and occupancy levels of shared spaces we can manage the risk of airborne infection by a virus such as that which causes COVID-19.”
Professor Andrew Curran, Chief Scientific Adviser at the Health and Safety Executive and lead for the PROTECT study, added: “This important research demonstrates that, while the airborne transmission route can be a significant contributor to COVID-19 infection risk in places such as offices and schools, there are achievable steps that can be taken to reduce this risk and help facilitate a safe return. Ensuring adequate ventilation is a key element, and the appropriate use of tools such as CO2 monitoring can give building managers a much better understanding of their own ventilation systems and how they are performing for each activity undertaken in the space.
“However, the airborne route is just one of three known routes of transmission of the COVID-19 virus. Close-range person-to-person and surface transmission risks must also be assessed, and relevant measures applied to control all routes of exposure for all activities where risk is identified. For most businesses, a COVID-19 control strategy will involve a blended combination of measures identified through a risk assessment – there is no silver bullet.”
Professor Charlotte Deane, UKRI Director for the COVID-19 Response and Deputy Executive Chair of the Engineering and Physical Sciences Research Council, said: “A key challenge throughout the pandemic has been to understand how this novel virus is transmitted and to develop measures which could be implemented to curb the spread of infection. This study highlights that research and innovation supported by UKRI and the National Core Studies programme is continuing to evolve our understanding of the virus and helping us to develop knowledge which will be key to the global post-pandemic recovery.”

What you’ll get: Beverley Magistrates’ Court heard that MS Properties (Northern) Ltd had not commissioned a refurbishment asbestos survey prior to the work commencing. Employees removed over 1000m2 of asbestos insulation board (AIB) ceiling tiles in an uncontrolled manner, exposing them to asbestos.
The HSE’s investigation found that the company’s director, and the casual labourers they employed, spent approximately three to four weeks removing the suspended ceiling, along with the ceiling tiles which contained asbestos, to install new stud walls to divide the shop floor into separate units. The labourers were unskilled and untrained. They were provided with a claw hammer to knock the tiles down. The asbestos-containing tile debris was then shovelled or collected into approximately 62 one tonne bags.
MS Properties (Northern) Limited of Beckside Business, Beckside Road, Bradford, pleaded guilty to breaching Regulation 5 of the Control of Asbestos Regulations 2012. The company was fined £16,000, ordered to pay £3,011.87 in costs and a victim surcharge of £190.
After the hearing, HSE inspector Trisha Elvy commented: “If the company had identified any asbestos on the site through a refurbishment asbestos survey, carried out by a competent surveyor, and had it removed by licenced asbestos removal contractors prior to the refurbishment work commencing, then MS Properties (Northern) employees would not have been exposed to asbestos.
“No matter how small or large your company, there is a need to prevent exposing your employees and the public to asbestos by ensuring that it is identified on site prior to any work commencing.”
