Just because an equipment


operator is sat in a


comfortable, air-


conditioned


cab does not necessarily


mean that he is protected from the


harmful and potentially


fatal effects of airborne dust and


contamination.


Face-fitted masks and other forms of Respiratory Protective Equipment (RPE) are now commonplace on many UK demolition sites. Indeed, to many site operatives, the face mask is as much a part of their daily life as a hard hat or


a bacon sandwich. Of course, this doesn’t generally apply to excavator


operators. Tucked away in air-conditioned, bullet-proof glassed splendour, excavator operators are isolated from dust, particulates and gaseous emissions. Or are they? Modern machines are, of course, fitted with cabs that benefit from filtration systems to ensure that the air breathed by operators is clean and healthy. But that doesn’t necessarily mean that excavator operators are entirely safe from dust and particulates. “For one thing, no cabs are as well sealed as contractors might believe,” explains Trans Elektro’s Ronald van Egeraat. “Furthermore, traditional in- cab filtration is only as good as the filters fitted that are smaller compared to ours, the design of the system, no cabin pressurisation can be guaranteed and the regularity and thoroughness with which filters are replaced and maintained.”Standard procedure is that cabins always need additional sealing. A cab is a true pressurized cab because of the ventilator in the filter


system. This fan automatically pressurizes the cab at 100Pa where the HVAC doesn’t have this function. In fact, when that is switched off, you don’t have pressurisation and filtration at all.
