FILTER PRESSURISATION SYSTEMS

Improving Cabin Air For plant operatives

H69.01

This guidance document which has been written by AfOR member BMAir, to provide infor-mation to site and H&S managers as to how they can reduce the risk to site operatives in respect to cabin air quality when operatives spend prolonged or frequent periods of time within a mobile plant cab.

TAKING CARE OF PLANT OPERATIVES’ HEALTHAt biowaste sites, plant operatives need to be protected against exposure to potentially hazardous or toxic elements like bio aerosols, organisms, spores and (odourless) gases. The risks and long-term health effects of exposure to a combination of these components is all-too-often underestimated. But there is a solution to overcoming these concerns. Standard mobile plant can be equipped with an Air filter system that guarantees the operator is provided with an environment with Clean Cabin Air and with cabin air quality which can be continuously monitored. AfOR as part of their commitment to promoting Health and Safety within the bio waste sector are keen to provide information on products which are beneficial to member operators.

WHY THE USE OF A BMAIR CABINFILTRATION SYSTEM?The presence of bio aerosols at bio waste recycling sites is well known, and research has proventhe presence of a number of gasses like ammonia or carcinogenic Volatile Organic Compounds.Complying with COSHH and reducing exposure to the minimum is therefore of utmost importance. Because the recycling sector is a relatively young industry, the long-term health effects of exposure to this cocktail of components is not yet fully known. What has been proven, however, is that exposure to certain substances in general may lead to occupational diseases often associated with respiratoryconditions. This may result in an increase in absenteeism through sickness and longterm illness. Beside the human effect, this results in serious extra costs for companies. An Air filter system such as the one supplied by BMAir can guarantee Clean Cabin Air, providing Operators with a healthier working environment complyingwith COSHH, thus eliminating or reducing exposure to a minimal level. Units can be retrofitted and do not in any way compromise

WHAT DOES BMAIR HAVE TO OFFER THE SECTOR?A BMAir system can contain a much bigger filter package than conventional systems and is supplied with an appropriate system controller. Systems up to 75 litres can be used. Only these systems can guarantee an adequate filtering of gasses up to 99% efficiency. For the particulates there is always a HEPA filter with a pre-filter available. The design of the BMAir system is done in such a way that it can easily handle high dust loading where conventional cabin filters can easily block BMAir offer a written guarantee as to its efficacy. Not all toxic components are able to be detected by the human nose. BMAir filter systems are designed to work in the same manner as Respiratory Protective Equipment, their use is well documented, and they have a CE registration mark based on independent laboratory tests. The system is designed to ensure that through the use of a pressure controlled fan, there is always a controlled maximum amount of air passing through the filters creating the predefined cabin pressure of 50 or 100Pa, regardless of the speed of the cabin’s original ventilation system.

A SMART PRESSURIZED CABINAt the installation of a bespoke BMAir system, the cabin is additionally sealed to optimise the operation of the filter unit and to control filter costs. A positive cabin pressure prevents polluted air entering the cabin through joints and seams. A cabin certificate supplied after installation informs the customer with all specific information on the pressurized cabin and how to ensure the system is used efficiently.

TOTAL COST OF OWNERSHIP AND SERVICEWith a BMAir filter system installed, the cabin properly sealed, and with filters changed at the required intervals, this total package is available at a starting price of just a few pounds per day depending on the filter package. Optional service contracts are available, ensuring that filter changes and system checks are carried out by trained staff.

REQUIREMENTS HSE AG-7 VEHICLE AIR FILTRATION

The BM-Air filter pressurization system can be mounted on the cabin roof or on the rear deck of most loading shovels . Where roof height is an issue the latter option in favoured. Contaminated air is drawn in through the filter pressurization system inlet. Initially the solid particles are filtered out, then air passes througha HEPA filter. Gas and vapour filtering is taken care of by the active carbon filter(s). The inbuilt monitoring system checks for constant pressure, air quality and filter life. Surplus air will flow out of the cabin via joints and seams. In order to show the operator that the system is working as designed, an optional green light on top of the cabin indicates that the system is fully functioning. If you value the health of your employees who may spend in excess of 8 hours a day in a hostile working environment, then visit www.transelektro.com for further information

INSTALLATION AND OPERATION

AG 7In compliance with

The longterm health effects symbol was introduced in 2009.

BMAIR FILTERSYSTEM IN COMPARISON WITH AG7The AG7 guidance (reissued August 2011) is available from the HSE. This document was initially written with the farming community in mind and helps operators to comply with COSHH regarding composting at IVC or open windrow sites.
