PLANT & MACHINERY SAFETY

SAFELY AT ALL TIMES.”
able to advise on the most suitable water treatment regime for the boiler house, ranging from a dedicated water treatment system such as reverse osmosis through to a pressurised deaerator solution.
Take operation and maintenance as an example. Post installation, during the lifetime of a boiler, a number of changes could be made to the plant or its associated infrastructure. These changes, whether physical modifications to the boiler itself, or a change in monitoring arrangements, can affect the way in which the boiler is operated. Changes to a boiler’s original design limits can, for example, cause increased risk of stress, corrosion or even fatigue of key components. It’s therefore important to ensure a record has been kept of how the boiler should be correctly operated and maintained, and that this documentation is followed at all times.
Water treatment is another important area for consideration. It is vital that measures are put in place to reduce the risk of overheating, corrosion, and water carryover. So for any plant operator looking to maintain water quality in a system where water is heated, and where there is a potential for scaling, it is best to consult a water treatment expert. They will be

Routine examination is also key. Regulation 8 of the Pressure Systems Safety Regulations (PSSR) 2000 covers the safe design and use of pressure systems and is intended to prevent the hazardous storage of pressure.
A legal requirement of regulation 8 is that a written scheme of examination is drawn up for all relevant plants. This scheme should highlight the nature and frequency of examination for the pressure system, as well as build an accurate picture of the system’s component parts.
It’s imperative that this scheme is certified by a competent person who will ultimately be responsible for making recommendations and key decisions to ensure the equipment within the plant is being operated safely. This could be anything from advising the owner or user on the content of the written scheme of examination, to issuing a report of examination and notifications of any potentially dangerous defects. While the term ‘competent person’ is subjective, depending on the setting in which it is being used, anyone acting as a competent person should have
experience of the actual systems involved, not to mention sufficient practical and theoretical knowledge.
KNOWLEDGE IS POWER In the boiler house, a degree of practical and theoretical knowledge is vital to ensuring the equipment and processes are operated safely and correctly. So it is no surprise that knowledge and experience is a recurring theme throughout the INDG436 document.
This is, however, an ongoing process. Technologies are constantly developing and the demands on systems change over time. As a result, it’s not enough to take on board key operating principles or working processes at the start of a job or following the introduction of a new piece of equipment, for example. This knowledge needs to continually evolve over time to ensure it remains current and this generally requires regular reviews of expertise and competencies. From there, the development of an appropriate training programme can follow, with the ultimate aim of ensuring the HSE’s competence factor is fulfilled at all times.
It would seem the HSE is in agreement with this approach. INDG436 highlights training as one of the crucial factors governing the safe operation of the boiler; it also provides guidance on how to identify a quality training provider. It states that training should be delivered by qualified equipment specialists, who can convey their knowledge in the appropriate context. Industrial experience is also key. So when choosing a boiler house risk assessment provider, it’s important to look for a course designed not only by a health and safety expert but also by a provider with vast experience in the boiler house environment.
Risk assessments play an essential role in any safe working environment and keeping up-to-date through training will ensure operators have confidence in their ability to carry out procedures correctly and safely. Successful management of risk will not only help to prevent accidents but will proceed to enhance overall business performance.
