Whatever your business, I’m sure you are trying to get your head around the crazy new world that we are living in.
The asbestos removal industry is pretty good at hazard identification, risk assessment and mitigation and all our personal protective equipment (PPE) is of the required grade. The other way to look at the immediate future is that we have a particular skill set, in that we clean up contaminated surfaces whilst keeping our workforce safe. As an industry our core competence may be called upon in the COVID19 national effort.
The Secretary of state for Business, Alok Sharma, supportive letter to all businesses operating in the construction sector was seen as real boost for the entire sector. This encouraged many of the Tier 1 contractors to reopen sites and insist that their subcontractors support them.
This will present significant challenges in the coming weeks as we all try and follow the latest government advice. The Construction Leadership Council have issued Site Operating Procedures. The highlights of the SOP are:
- Non-essential physical work that requires close contact between workers should not be carried out;
- Work requiring skin to skin contact should not be carried out;
- Plan all other work to minimise contact between workers
- Reusable PPE should be thoroughly cleaned after use and not shared between workers;
- Single use PPE should be disposed of so that it cannot be reused;
- Stairs should be used in preference to lifts or hoists;
- Where lifts or hoists must be used – lower their capacity to reduce congestion and contact at all times;
- Regularly clean touchpoints, doors, buttons etc;
- Increase ventilation in enclosed spaces;
- Regularly clean the inside of vehicle cabs and between use by different operators.
The underlying point of all this is critically we need to observe social distancing. I’m going to reword that for clarity: physical distancing. Because the ‘social’ bit makes us think that it is something we consider after work.
Physical distancing is keeping two metres away from anyone that you don’t live with – that’s likely to mean everyone you work with. The HSE will be all over whether we are succeeding and have a lot of powers to close down sites if they feel it appropriate.
I’ve been considering how – and whether – we can continue to work safely in the current circumstances, and I wanted to share my thoughts in this post. But there’s a big caveat: I am not an expert virologist. Instead I’m drawing on my experience of hazard identification and mitigation. I believe these are all areas we should be thinking of. If you have anything to add, and especially if I have said something stupid, please shout asap.
Working through the steps to the following are some of the decision / hold points that we need to consider.
Let’s start by looking at the risk hierarchy:
- Engineering Controls (e.g. physical barriers)
- Administrative controls (e.g. procedures)
If our starting point is that the only ‘safe’ place is in an individual’s own home, it is possibly helpful to think of any asbestos-removal job as though the site is thoroughly contaminated with rat urine or pigeon guano. But where does ‘the job’ start and finish? We have to change how we think. Where does the risk now start? What new areas do we need to think about?
Good reason for the job?
The government guidance remains that with the exception of key industries, we should be attempting to carry on. Here’s a link to the latest guidance on what should and shouldn’t go ahead. Certainly with Work carried out in people’s homes, including repairs and maintenance, can apparently continue, provided they can maintain 2 metre distance from any household occupants AND the household is not isolating or where an individual is being shielded. Here’s a link to the detailed guidance.
There are some examples of projects that will obviously be needed, where we may be remediating an existing risk, or facilitating oxygen lines in a hospital. The example of an asbestos removal job to facilitate a kitchen installation whilst is less clearcut, is not actually prohibited.
Remember that the point of physical distancing is that if we cut the number of people those carrying the infection pass it on to, by just 33%, the knock on effect over time is enormous:

Individual tasks should also be assessed – and where it is not possible to follow the social distancing guidelines in full, consider whether that activity needs to continue for the site to continue to operate, and, if so, take all the mitigating actions possible to reduce the risk of transmission. I go in to suggestions below.
Should I / they be at work?
You need to give very clear guidance to all workers on who should and shouldn’t come to work – and if they do turn up, when to send them home. Anyone who meets one of the following criteria should not come to work:
- Has a high temperature or a new persistent cough – follow the guidance on self-isolation
- Is a vulnerable person (by virtue of their age, underlying health condition, clinical condition or are pregnant)
- Is living with someone in self-isolation or a vulnerable person
If a worker develops a high temperature or a persistent cough while at work, they should:
- Return home immediately
- Avoid touching anything
- Cough or sneeze into a tissue and put it in a bin, or if they do not have tissues, cough and sneeze into the crook of their elbow
I would err on the side of caution.
Getting to / from work
Typically we might have a driver and two passengers in the front of a van. Clearly this is not physical distancing. You will need to start thinking how you can achieve this. Can the workers arrive at site separately via their own transport (remembering that public transport is for critical workers now)? Many operatives don’t drive, so how do you mitigate the risk?. Can you limit the number, for example by carrying only one passenger? Maintain travelling companions (i.e. keep to the same passenger). Face away from each other and open the windows to increase ventilation. Daily disinfecting of the vehicle cabin by the site team, no eating, drinking or smoking (all of which increase the chance of touching the face).
It could mean donning RPE, but half-masks have a limit for how long you should wear them. For longer journeys you’ll need to factor in regular breaks.
As a back-up it would probably be prudent to do regular full decontamination of the vehicles back in the yard – treat this like an ‘environmental clean’ with full face RPE and dilute bleach (1:60).
Induction and arriving
Again, physical distancing! Keep two metres away from anyone that you don’t live with – i.e. everyone you work with.
Setting up the Job
Again, is it possible to do the work and obey physical distancing? The nature of the property may help or hinder this (very small flats vs larger areas). Again consider the risk hierarchy. Just as with a site posing a psittacosis risk, we would ordinarily disinfect surfaces before we start, increase ventilation, introduce strict eating, drinking and smoking procedures, and require PPE (gloves, RPE and overalls). We’d also increase our washing frequency.
The normal challenge on sites is welfare, and that’s even more the case now. Again, if we are imagining that the area is thoroughly contaminated with rat urine or pigeon guano, we would obviously wash our hands before any break. We need to be thinking along those lines – but even more so. Workers should wash their hands on arrival at the site and then regularly after that. How can our guys frequently wash their hands for the required 20 seconds? They can use hand sanitiser if you have it, but this must contain more than 60% alcohol. Possibly better is a killer spray, with one person spraying whilst the second washes their hands.
Home-brew Sanitiser Recipe
- 75ml of isopropyl or rubbing alcohol (99 percent) – can be found online still
- 25ml of aloe vera gel (to help keep your hands smooth and to counteract the harshness of alcohol) – can be found online still
- 10 drops of essential oil, such as lavender oil, or you can use lemon juice instead.
I understand that this will come out much stronger smelling and thinner than you would expect. The ingredients are expensive online – but as you apparently only need a few drops, it should last. Remember that the advice is to ‘wash’ hands for at least 20 seconds, ensuring that every nook is thoroughly rubbed clean.
Welfare – Breakfast and Break times
I received a photo from a truck driver at one of the UK largest construction sites on the first day of the lockdown. It shows an enclosed canteen crammed with people just inches from each other – clearly madness.
The standard operating procedures published by Build UK – so hopefully this is a thing of the past.
It shouldn’t need saying, but DO NOT USE CANTEENS. Everyone should wash their hands before all breaks. There should be no crowding into the toilets – give everyone plenty of space and extra time if needed. Individuals should bring their lunch and drinking water from home – remembering that those working in a warm enclosure will need to drink plenty. There should be no eating together as a team. Stay at least two metres apart!
Clearly, we are very well protected in the enclosure, although possibly less so on semi-controlled jobs. It may be worth considering full-face powered RPE for all works as that also prevents people from touching their face. Similarly, full transit procedures for all works may be a good idea. You will also need to consider staggered use of the DCU – allow the first operative to exit, before the next one starts to transit.
Plant and Equipment
Thorough external cleaning – again using the dilute bleach solution (1:60). This should be done at the end of the project and before issuing it to site.
It’s much easier at the office, but still a challenge – again, the primary focus is physical distancing, so how do you achieve this?
- Everyone who can work from home should – this may require additional computers and consideration of home broadband services.
- Manage site operations remotely – can you reduce the number of site visits? Assure360 Paperless will allow you to review the progress of the job and ensure that all of the paperwork is being completed from the kitchen table.
- Virtual meetings and conference calls – for the past year we have used Zoom as a virtual meeting platform. Other services such as paperless solutions will help you manage remotely.
- Rota system to set times for team members to attend the office to carry out work they absolutely can’t do from home. Perhaps one day each, to keep them separate. Alternatively, modular working. It may be that you have an office set up that allows workers to work in their own office and not mingle.
- Delivery of stores and equipment – deliver to site to prevent unnecessary visits to the office. Consider setting up an external quarantine area for deliveries, and wipe down before it comes into the stores area.
- Hand sanitiser stations at entrance and throughout the office.
- Bring your own food, and create a rota for the kitchen.
- Limit who comes into the office further. Pause exterior contractors (cleaners, window cleaners etc) to reduce the vectors into the office.
It may be possible to have an unmanned reception for visitors and deliveries, showing a number people can call (on their own phone) to let you know they’ve arrived. This ‘high risk area’ could be disinfected after every ‘exposure’.
It needs to be remembered that the virus can, apparently, survive on some surfaces for several days. Staff should be encouraged to wipe down surfaces with dilute bleach or a soap solution, and frequently wash their hands.
However (and it’s a biggie), the advice is still uncertain. I started by saying that the government advice is that construction can go ahead, but the Mayor of London, Sadiq Khan, has said: “My view is no construction work unless it is for a safety reason.”
If, after all of this, you decide not to keep operating and you have spare stocks of PPE – our medics are in desperate need.
