Glue EMF — electromagnetic field control, for example in glue drying devices

Radio frequency sealers and glue drying devices were mainly used in the production of wooden materials like bent plywood furniture, window and door frames and board plates. ILO published a good practical guide in 1998 and the EU issued a Directive concerning electromagnetic fields at work. In Finland law stated the maximum levels of the exposure of workers. Due to legal obligation since 1985 many workplaces using high frequency electromagnetic devices were monitored regularly, with the aim of reducing exposure.
