4: Choose the Most Effective and Reliable Hazard Control Measures 

After you have narrowed down the different options for your hazard control measures, you need to choose the most effective and reliable. This will help you to ensure you consistently minimise the release and spread of the hazardous substance. It’s important to consider that some methods of control are dependent on variable factors. For example, protective gloves are only effective if they are the right size and used correctly. It is therefore much better to change a process to minimise the emission of a hazardous substance at source. Once you have established the most effective and reliable control options for the particular situation, they need to be focused on the primary source(s) of exposure. Seek professional advice to ensure the suitability of your hazard control measures. Remember, you may need to have your control measures professionally designed and engineered to ensure future reliability.

What Control Options are Available?

There are many different hazard control measures available. However, it is important to stress that you should consider the effectiveness of each control measure in their own right. Control measures vary from the complete elimination of the hazardous substance, to the use of PPE by exposed individuals. COSHH regulation 7 outlines some of the different options available. However, fundamentally there are three different ways in which hazardous substances can be controlled:

Substance Elimination

The complete elimination of a hazardous substance from a workplace is naturally the best possible solution; this approach should always be explored first. Here, there is no possible risk of exposure. Have you considered all of the viable alternatives to the use of the hazardous substance?

Process Change

If it is not possible to eliminate the hazardous substance, the next best option is to change the process to minimise its release. Changing a process is usually a more permanent solution. However, if it is not possible to do this, you will need to consider implementing external process controls.

Process Controls

Controls can be applied to the process to minimise exposure. Unfortunately, process controls are usually less reliable than process changes and generally require more significant and regular maintenance.

Why Process Controls are Generally Less Reliable

An example of a process control method is an LEV (local exhaust ventilation) hood. LEV controls and then removes contaminated air. However, its effectiveness depends on both the suitability and maintenance of the LEV system, as well as how the operator uses it. PPE is also subject to human error and misuse, meaning that although it may appear to be the cheapest and easiest solution, this is often in direct contrast with reality. The cost of providing more effective control options may actually be cheaper. Because of the high opportunity for variability and inconsistency in process control methods, they are generally less reliable and effective.

Developing Integrated Hazard Control Measures

You need to find an appropriate and integrated control solution that’s both effective and reliable as well as practicable and workable. You may use one control measure or a combination of different control measures in order to achieve this.

Finding an Appropriate Solution

Because of the number of different control measures available and the sheer variability in working methods and machinery, professional advice should be sought wherever possible. Ultimately, your solution needs to be engineered to your specific requirements. The result? A bespoke, reliable hazard control method that fulfils its intended purpose! However, it is essential to ensure regular testing and maintenance takes place to ensure all equipment and control measures are working as they should.
