Increased awareness of the need to ensure the health and safety of the users of pneumatic equipment has led to unprecedented levels of industry regulation.

For example, the Corporate Manslaughter Act is now in force, placing responsibility on business owners to ensure the safety of their employees.

The repercussions are serious, potentially including heavy fines, damaging publicity and even the possibility of criminal charges for managers.

Likewise, as of 2009, ISO 4414 will integrate EN 983 and safety standard 2006/42/EC, as well as additional standards for machine safety, to become EN ISO 4414 (ISO 4414 outside of Europe).

This will become the primary standard for workplace safety, requiring stringent measures to be taken to increase the safety of pneumatic applications.

Achieving a thorough understanding of the new regulations and guidelines can be difficult and time consuming.

This whitepaper offers a starting point for people responsible for ensuring the proper health and safety practices are implemented and adhered to throughout their organisation.

The Corporate Manslaughter and Corporate Homicide Act (CMA) requires business owners to ensure their employees work in compliance with the relevant health and safety standards, for example by providing them with the necessary training and equipment.

As a result there is now the potential for serious penalties if, following a death in the workplace, the business is found by a jury to have behaved negligently.

These penalties can include: fines of up to 10 per cent of the average annual turnover of the business; publicity orders, which can be used to force a business to publicise its misconduct by posting information on its website, writing to shareholders and placing advertisements in the media; and punishing company managers or directors individually, with, for example, prosecution, a fine or even a prison sentence.

The Provision and Use of Work Equipment Regulations 1998 (PUWER) states that employees must be provided with a safe working environment and equipment that is: suitable for use; suitable for the purpose and condition in which it is used; maintained in a safe condition for use so that people’s health and safety is not at risk; inspected in certain circumstances to ensure that it is, and continues to be, safe for use.

Management should also ensure that risks created by the use of the equipment are eliminated where possible or controlled by taking appropriate hardware measures.

In 2009, ISO 4414 will become EN ISO 4414 (ISO 4414 outside of Europe), replacing both EN 983:1996 and BS ISO 4414:1998 as the primary safety standard for pneumatic applications.

The changes will include refinements and revisions to increase operator safety.

Perhaps most pertinent to the managers and operators of applications using compressed air is the section on the failure of hose assemblies and plastic piping (EN ISO 4414 5.4.5.11.1 / ISO 4414 5.4.5.11.1).

The proposed revision states that when the failure presents a whiplash hazard, it must either be restrained, shielded or incorporate an air fuse.

The latest generation of air fuses, such as Parker Hannifin’s Moduflex Airguard system, offer business owners a simple method of improving the safety of pneumatic equipment that complies with CMA and EN ISO 4414 5.4.5.11.1 / ISO 4414 5.4.5.11.1.

As a result, the safety risks associated with broken compressed air hose, tubes and pipes can be minimised, protecting employees from harm and businesses from the serious consequences of negligence.

The technology ensures the main air flow is immediately shut off if the volume of air exceeds a set value, which is factory preset to allow normal air consumption when using air tools.

If the air consumption exceeds the set value for the device, for instance, in the event of the air line being severed, then the internal piston instantly shuts off the main flow.

An integral bleed hole allows some air to flow though, enabling the line pressure to automatically reset the air fuse once the line break is repaired.

The compact, lightweight devices have been designed to provide a simple safety mechanism for a range of pneumatic applications, system pressures and hose, tube or pipe sizes.

Stainless steel versions are also available for use in food and drink, healthcare and offshore.

The components can be fitted quickly and easily, with no adjustment necessary, to provide reliable tamperproof protection.
