Within the manufacturing industry there are a lot of rules and regulations which users need to comply with. Over many years there have been a lot of changes to the British and International safety standards, adding more rules & regulations. This is all consistent with the objective to make the manufacturing industry a safer working environment.

10 things to know about machine guarding standards

Guarding needs to be well designed if a machine is to operate safely and efficiently. Furthermore, guards should not be expensively over-engineered, nor should they detract from the machine’s aesthetics. In all cases, however, they should be designed in accordance with the applicable national and international standards.

A new list of Machinery Directive harmonised standards was published on 13 May and this includes, for the first time, EN ISO 14120. Most importantly, this new standard for fixed and movable guards superseded EN 953 on 31 May and there is no transition period.

Machine guards are normally designed to prevent workers from accessing hazardous parts of machinery and to protect against ejected parts. However, there is another risk that is not always given adequate consideration, namely hazardous substances emitted by machinery, which is covered in BS EN ISO 14123-1:2015.

Procter Machine Guarding has published a free White Paper that explains the differences between BSI’s published document PD 5304:2014, Guidance on safe use of machinery, and the 2005 edition that is now superseded.

Procter Machine Guarding has published a free White Paper that explains the differences between the new international machine guarding standard ISO 14120 and the European standards it is replacing, EN 953.

A new Guide to Machinery Guarding Standards has been published by Procter Machine Guarding, this being the tenth edition of ‘On Your Guard’.

Procter Machine Guarding has redesigned its popular free Risk Assessment Calculator in line with the requirements of the recently published international standard EN ISO 14121-1:2007 (Safety of machinery. Risk assessment. Principles), which has replaced EN 1050.

Falls from height remain the biggest cause of death in the workplace, with 67 recorded in Great Britain in 2003/04. It is believed that many of these deaths could have been avoided if sensible measures had been taken. In addition, nearly 4000 people suffered a serious injury as a result of a fall from height in the workplace during the same period.

Any machine placed on the market within the EU must be CE marked in accordance with the Machinery Directive – and this includes machinery that is built in-house for use in-house. One of the most critical aspects of compliance with the Machinery Directive is guarding, for which several standards are applicable, the most important being BS EN 953: 1998, Safety of machinery – Guards – General requirements for the design and construction of fixed and movable guards.

Jeremy Procter, Convenor of the European Standards Committee responsible for Machine Guards, and Managing Director of Procter Machine Guarding, looks at the standards relating to the safety of food and drink machinery.

On 14 June 2007 the European Court of Justice (ECJ) upheld one of the key elements of British health and safety law, namely the use of the phrase ‘so far as is reasonably practicable.’ This was despite the European Commission’s claim that using ‘so far as is reasonably practicable’ did not implement the Framework Directive (89/391/EEC) on EU employers’ duties to protect the health and safety of their workers, as the Directive has no such qualification. The ECJ dismissed the European Commission’s case and ordered it to pay the UK Government’s costs.

One of the most important standards relating to machinery guarding is BS EN 294: 1992, ‘Safety of machinery – Safety distances to prevent danger zones being reached by the upper limbs’, yet many machine builders are thought to be using their ‘best skill and judgement’ rather than working to the standard. This is no excuse, because compliance with the Machinery Directive – and, subsequently, CE marking – requires adherence with all relevant standards, and BS EN 294 is certainly relevant to most, if not all machinery.

Jeremy Procter, a Member of BSI’s MCE/3 committee, Convenor of the European Standards Committee responsible for Machine Guards (CEN TC114 WG11), and Managing Director of Procter Machine Guarding, looks at BS EN 953:1997 +A1:2009 and compares it with its predecessor.

The HSE’s reports from accident investigations often show a generally unsatisfactory standard of guarding, and an over-reliance on systems of work and the ‘skill’ of operators as the principal means of risk reduction.

Procter Machine Guarding has updated the page on its website listing
standards and other publications relating to machinery safety, including
machine guarding.

To clarify the situation relating to CE marking assemblies of machinery under the Machinery Directive 2006/42/EC, the HSE (Health and Safety Executive) has published a new page on its website entitled ‘In situ manufacture or assembly of work equipment and plant.’

During the first half of 2009 there were numerous prosecutions relating to inadequate machinery safety. This is not as a result of a targeted clamp-down, but follows a series of accidents that have led to workers being injured.

‘Making paper safely’ is a phrase that has been used within the papermaking industry for around one year now, thanks to a campaign initiated by the HSC (Health and Safety Commission) to improve the safety record of paper mills. The HSC Paper and Board Industry Advisory Committee (Pabiac), which includes representatives from the industry and unions, last year published new guidance called Part 6, Making paper safely: managing safety in the papermaking process (ISBN 0-7176-1907-9, priced £8.00).

A new section of the Health and Safety Executive (HSE) website is now online, dedicated to the needs of the printing industry. Each year, printing companies report approximately 1400 work-related accidents to the HSE; over 200 of these accidents are classified as major injuries such as fractures and amputations. Contact with machinery is one of the most common types of accidents suffered by printers, with others being manual handling and slips/trips.

Towards the end of January 2005 the HSE (Health and Safety Executive) and the EEF, the manufacturers’ organisation, signed a groundbreaking partnership agreement to promote effective health and safety management across manufacturing industries throughout England, Wales and Scotland, establishing close links between staff operating in every region.
