FOLLOWING Prime Minister Boris Johnson’s nationwide address and the publishing of his ‘road map’ to gradually ease COVID-19 lockdown restrictions and get people back to work, businesses across the country are now thinking about how and when they can safely re-open their doors.

However, before they do so, the country’s largest independent security and facilities management company, has warned that premises should be cleaned, disinfected and sanitised to protect returning staff and customers – with regular cleans scheduled thereafter to help prevent the virus returning.

Lisburn-based Mercury Security & Facilities Management (MSFM), which provides a specialised deep cleaning service designed to eliminate COVID–19, is also urging companies not to leave it too late to book their deep clean, or they could face a further wait before returning to action.

“The Prime Minister has now given the green light for employees in certain sectors to start returning to work,” said MSFM Commercial Director Bernard Bogues.

“On Sunday, Boris Johnson paved the way for staff who cannot do their jobs at home to return to work, highlighting the manufacturing and construction industries as examples.  This will be followed very carefully and gradually by the re-opening of shops, schools, offices, restaurants and many more besides.

“Never has it been more important to ensure the environment in which we live and work in is being cleaned and maintained to the highest of clinical standards, so for the easing of these lockdown restrictions to work, it is vital that premises undergo a deep clean to sanitise the entire area,” he continued.

“Companies simply cannot afford to take chances with the health and safety of their employees or other visitors to their premises and risk a second wave of the virus.  With so many businesses currently in lockdown, the demand for specialised deep cleaning services is sure to be extremely high – so we would advise owners to book as soon as they have a return date – to prevent any further frustration and delay.

“At Mercury, we’ll be carrying out deep cleans on a ‘first come first served’ basis,” added Mr Bogues.

“It’s also vital that, having safely re-opened their doors, companies schedule regular cleans going forward  to minimise the risk of the virus coming back. We’re far from out of the woods just yet.”   

Carried out by operators fully equipped with appropriate PPE (Tyvek suits, gloves, masks etc), a typical MSFM disinfection includes risk assessment, area isolation, zonal disinfectation, random swab tests and waste removal, with a fully comprehensive report and certificate provided on completion.

“This is not a standard deep clean that one can get any day of the week,” continued Bernard Bogues.

“It is very specialised and requires great care and experience, so it is important to use a qualified, experienced and reputable firm as there are a number of ill-informed companies out there offering ’preventive’ disinfection.

“At MSFM, we have completed successful specialised deep cleans for a lot of companies in NI and beyond, including office, commercial, call centre, manufacturing, clinical and nursing home environments.  We can sanitise and clean areas using approved grade disinfectant and with the use of ‘ fogging’ and our highly specialised ozone generators, we effectively and efficiently eliminate and reduce any further risk,” he concluded.

MSFM has been busier than most since the Coronavirus outbreak.  As well as the deep cleaning services it provides, Mercury’s security division has been providing a range of security solutions to help business owners protect their empty properties during lockdown and prepare for getting back to business.

The company has recently launched the Mercury TC-1 thermal camera which will offer much needed reassurances to returning companies and staff by enabling the speedy detection of a high body temperature or fever – one of the first vital symptoms displayed by carriers of the Coronavirus – in just under a second.

All of these services are provided and integrated using the state-of-the-art Intelocate management software system which records actions, collects data, produces reports and stores in one central system to enhance communication in an organized, transparent and confidential manner.

“We appreciate that this has been an extremely challenging and worrying time for people at home and throughout the world,” said Mercury CEO Frank Cullen.  “So at Mercury, our staff have been working around the clock to proactively try to slow the spread of COVID-19 and help companies stay safe, manage the risk that it  presents and, importantly, get back to work.”
