Vacuums are fantastic for removing loose powder or granulates that have collected in a silo but are less effective at removing ratholes – materials that have bonded to the internal silo walls. However, it is also restricted in what it can achieve. One of the major advantages of vacuuming is that it doesn’t require anyone to enter the silo to work, therefore it minimises health & safety issues surrounding the clean. It is done either via a large, truck-mounted vacuum that is fed into the silo, or, in more modern silos, a vacuum can be built into the system design. Vacuuming is generally the first step employed to clean a silo used to store powdered, granular or liquid products. That said, the main methods are vacuuming or using a silo whip. How you clean a silo often depends on what it is being used to store and which part of the silo you want to clean. This is the safest and most responsible approach to silo cleaning, and it doesn’t compromise the quality of the end result.

Thankfully, however, the risks of entering a silo can be completed avoided with our cleaning methods, which can be applied, giving your silo a thorough clean, with operatives remaining outside. It is not enough just to rely on the emergency services, as not having a comprehensive plan in place could leave the silo owner liable.Īlso, specialist equipment must be provided such as respirators, the right tools for cleaning the silo, and of course, all the necessary PPE.

Such a plan would also need to include contingency planning around what to do in case of an emergency, such as a fall inside the silo or what to do if a worker is overcome by fumes.

If someone is going into a confined space and there is not enough oxygen to breathe properly, you must provide breathing apparatus or ventilate the space to increase oxygen levels before entering.

If there is a risk of liquids or gases flooding in, you should establish whether the valves can be locked shut.

If a confined space has noxious fumes, you should consider how these can be ventilated or removed.

Such a plan would include aspects such as: This includes carrying out a risk assessment of the work and putting a plan in place before it commences. The Occupational Safety and Health Administration (OSHA) define silos as a confined space which means any workers entering one must follow the standard procedures for an enclosed hazardous area. There are a number of potential hazards inside any silo such as the potential for falls or impacts with the inside walls of the silo, lack of oxygen, immersion and even the risk of drowning in the materials stored in the silo if liquid or finely milled products like sugar or flour. We employ these methods because entering a silo can be extremely dangerous for workers and should be avoided if at all possible. The silo cleaning methods we use don’t require anyone to enter the silo, meaning they are relatively straight forward operations from the health & safety point of view. Cleaning a silo can be a very dangerous job, and it is vital that those who carry it out are as safe and protected as they can be. However, there is another incredibly important aspect to consider – so important we’ve decided to address it first. There are a number of ways of cleaning a silo and a host of tools available to carry that out, all of which we’ll cover in this article. This is particularly the case if they are being used to store human foodstuff or animal feeds as it ensures mould doesn’t build up to unacceptable levels, and that the contents are kept as fresh and palatable as possible. Silos need to be cleaned a minimum of once a year, but every six months is preferable. Of course, it adds unnecessary cost to a job too, not to mention stress and potential penalties if production is stopped.

This can delay production for weeks while the silo is evacuated, cleaned out, and refilled, and can lead to a considerable waste of product. A build up of debris over time can lead to clogging or a complete blockage in a silo, preventing the flow of material inside, be it cement, oil, grain, flour, chemicals or any other powdered, granulated or liquid product.

Ensuring that your silos are clean is the key to making sure they are functioning correctly.
