Some of the C.O.S.H.H. And Ventilation Safety Requirements

The Control of Substances and Hazardous to Health Regulation 2002 (C.O.S.H.H) are meant to help employers control the exposure to chemicals. They are meant to generally protect the workers from the effects of such chemicals by ensuring that proper ventilation safety mechanisms are put in place to minimize the dangers of such exposures. C.O.S.H.H essentials are easy to follow procedures used to control ventilation. They provide good practice and advice on the general ventilation to enhance safety. The guidelines can be applied to small, large and medium use of liquid and solids. The guidelines describe the important points that employers must follow to reduce dangerous exposure to a manageable level.

Dust extraction companies such as Dust Extraction Online work to standards of the C.O.S.H.H. regulations. They are very experienced in installing dust extraction systems and you can find them on Facebook if you are looking for an installation.

The reason why C.O.S.H.H guidelines, must be followed is that there are plenty of chemicals in work places which are not just dangerous but are corrosive and flammable. Such chemicals must be controlled and their release to the atmosphere regulated depending on the scale of work. As an employer, it is prudent that you consult your local authority so that the release of such substances in the atmosphere is regulated to reduce and prevent pollution. There are always special agencies that will advise you on the legislation concerning cleaning and discharging emissions.

However the general C.O.S.H.H. and ventilation safety guidelines revolve around the following:

Access- working areas should only be accessed by individuals who work in that area.

Design and equipment- as an employer, it is necessary that you provide a good standard of ventilation. It could be natural ventilation that normally provided by the windows, doors or openings as well as other controlled ventilation such as supply and removal of air using a powered fan.

If it is an office, the openings that supply general ventilation must be sufficient to control the dust and the vapor coming from any activity that may be taking place in the office.

If it is a factory, additional ventilation must be provided to help remove the contaminated air or replace it with clean air. This can be done using a mounted fan that extract and supply air in the factory. It includes venting air through airbricks, louvers, and ducts. It involves use of simple and complex air supply and removal systems. It is mandatory to ensure that the air supplied comes from areas that are not contaminated.

In addition one must ensure that the air supplied is enough and is sufficient to dilute and remove dust and the vapor produced. It is recommended you ensure that there are 5 and 15 air changes per hour. Also, it is necessary to ensure that air is discharged away from the windows, doors, and any other inlets you may be having on your building.

If there is dust in the room, one needs to re-circulate filtered air into the workroom. However, if the workroom has vapor, don’t re-circulate air in the room. Thus, it is mandatory that you ensure the air being re-circulated in the work room is coming from a fresh source. One must ensure that sufficient air flows past the work activity to the extraction point.


As an employer, it is imperative that you maintain the system as recommended by the supplier or the expert who installed it. This ensures that the equipment is in an effective and an efficient order.

Examination and Testing

Ensure that you get the correct information from the manufacturer on the design, and the performance of the ventilation equipment. If it is not possible to get the specs from the manufacturer, getting an opinion from a competent ventilation engineer could be ideal. The information obtained from the ventilation expert should be kept to allow for comparison with future test results.

It is advisable that you visually check the ventilation equipment at least once per week to ensure that is working.

You need to get the ventilation tested and examined against its performance and ensure that you keep all the records of the tests for not less than 5 years.

Cleaning and House Keeping

The working area and the equipment must be cleaned on a daily basis. The entire workroom can be cleaned once per week. If there are any spills they should be dealt with immediately. Avoid cleaning with dry brushes and compressed air. Using a vacuum cleaner and a wet clean is recommended.

Information About Health And Safety Audits

Do you wonder what a health and safety audit is? If you are, then there are probably a few questions you have about it, other than what it is. If you do want to know about health and safety audits, then continue to read the rest of this article, as it will explain what they are, as well as provide you with a lot of other useful information. The best kind of health and safety audits are carried out by qualified health and safety consultants such as DDS International (their promotional video is below).

1. What Is A Health And Safety Audit

A health and safety audit is exactly what it sounds like, it is an audit of the health and safety of an establishment. Many types of establishments go under a health and safety audit, and some of these businesses include restaurants, retail stores, construction sites and so forth. Just about any type of business can have this type of audit conducted, but the number of times a company will have such an audit conducted depends on a few factors, such as the type of business it is and whether or not there is a law that requires them to do an audit a specific number of times per year.

2. Who Conducts It

As for who conducts the audit, that depends on a few factors too. Some businesses conduct their own audits, which may be performed by a certain group of people within the company, such as health and safety experts, or a government agency or city officials may conduct a health and safety audit. Some companies have their own rules when it comes to audits, and if they do, then they usually decide when and who will conduct it, while an agency may have a certain person/persons conduct an audit at a certain time/day/month and so forth.

3. What Happens During An Audit

As for what happens during an audit, generally speaking a person will be in charge of auditing a company or site’s premises to determine if there are any health and safety risks or to determine if a company is following rules and regulations in regards to health and safety. This means that when an audit takes place, a thorough walk-thru will take place and an inspection of relevant equipment and installations will also take place. What happens during an audit depends on who is conducting it, but usually at the end of an audit, a report will be written up, and this report will include information to the audit’s findings.

4. Benefits Of Having An Audit

Companies may not be required to have a health and safety audit conducted, but they should consider having one done because there are quite a few benefits, with one of them being that a company will be able to identify if there are any health and safety risks on their premises. This will allow them to make important changes that could end up improving the working environment, as the company will be able to create a healthier and safer working environment for everyone. Also, if there are certain criteria that a company needs to meet in regards to health and safety, and they are audited by an agency, then they will be able to find out if they meet the requirements after the audit has been performed, and if they don’t meet the requirements, then they can fix the things that need to be fixed in order to bring everything up to standards.

5. Other Things To Know

There are a few other things to know, such as health and safety audits are often necessary, regardless of whether or not they are required. Also, if a company hires a professional company to conduct an audit, then it may cost them a few dollars, but it is often worth it. A health and safety audit can give a company peace of mind, even if the audit does not result in what they had hope for, as they will know what exactly what needs to be fixed and addressed.

As you can see, there are quite a few things you should know when it comes to a health and safety audit. If you run a company, then you should consider having an audit done, regardless of how small or big it is. You will find that an audit can provide you with a lot of benefits.
