S525 Certified Cabs Shouldn’t Be Used in Lieu of PPE 1 S525 Certified Cabs Shouldn’t Be Used in Lieu of PPE The American Society of Agricultural Engineers (ASAE) now recommends using agricul- tural cabs certified to meet ASAE standard S525-1.1 as a supplement to personal protec- tive equipment (PPE), rather than as a replacement for it. S525 was initially created to 2 Protection: Cabs certify specially equipped cabs intended to provide equivalent protection of some specific on Sprayers and Tractors PPE listed on pesticide labels. Two main features of S525-certified cabs are special cab filters for removing organic pesticide vapors, and positive-pressure ventilation. These cabs use filters with a tested and 3 Custom Hay Balers, Take proven efficiency at removing pesticide vapors to provide a supply of filtered air to the Note climate-control system in the cab. In addition, the cabs are well sealed and maintain higher pressure inside the cab, so any air leakage would be of filtered air leaking out rather than of contaminated air leaking in. An in-cab pressure indicator is required so the 3 Systemic, Local Systemic, operator can monitor the pressure and be assured that the filtration system is functioning or Translaminar: What’s the properly. Low in-cab pressure could indicate excessive air leakage (as from a poorly sealed Difference? door) or a plugged air filter in need of replacement. US–EPA personnel endorsed S525 in 1998, allowing operators of equipment with 4 Study Shows Turf certified cabs to spray without some specific forms of PPE. The standard was developed Break Down with the expertise from many areas, including equipment manufacturers, regulatory Rapidly agencies, and universities. According to the ASAE, additional information has revealed more areas that need to be investigated and addressed besides what was initially considered during the development 5 Pesticide Update of the standard. Because of this, the ASAE recommends that S525-certified cabs not be used in lieu of PPE; rather they should be considered a supplement to PPE. All operators of sprayers equipped with such cabs should follow all pertinent PPE requirements stated on the pesticide label.
