MDHS 82/2 The Dust Lamp
HSE guide on the use of the Dust Lamp. Great tool as the images on this guidance note show.
The Dust Lamp will show all dust but it is particularly impressive when it comes to the Respirable fraction of dust which would normally otherwise be invisible under normal lighting conditions. Uses the Tyndall effect (back scattering of incident light).
Can be used to scan the area in front of a hood (being used to control a dust producing process) to determine the effectiveness of the hood. Can also be used to audit work processes to determine areas where controls may be required.
