Definitions

  • the present invention relates to a dust sampling equip ⁇ ment which can be used to collect airborne dust.
  • dustsamples can be collected in preparation for measuring the quantity of dust which is to be found in the air in terms of dustmass per cubic meter of air.
  • the equipment is creat so that it can maintain one or several test samples with an adhesive, transparent test reception media and furthermore it includes devices which make it possible to attach the e- quiproent to a person.
  • the invention is primarily intended for collection of dust samples to additional analysis which can determine the amount of dust in the air at the place examined, and to a mi ⁇ nor degree determine the amounts of different kinds of par- ticle sizes even though the tests also will provide an option to do this.
  • the equipment can be used for bacteriologi ⁇ cal sampling if necessary with another kind of basic material at the test surface.
  • the invention is explained more explicitly in the fol ⁇ lowing with reference to the drawings at which
  • Fig. 1 is a stereoscopic picture of the dust samp ⁇ ling equipment according to the invention.
  • Fig. 2 is a stereoscopic picture of a sampling tren- cher.

  • Fig. 5 is a stereoscopic picture of a sampling tren ⁇ cher designed differently and
  • Fig. 6 is a stereoscopic picture of the equipment placed on a person by means of a strap.
  • Fig. 1 shows a dust sampling equipment which includes a vertical plate divided into an upper trencher holder la and a lower trencher holder Id. On Id is placed a horizontal tren ⁇ cher holder lb which is designed to carry two test trenchers 2 - one at the top side and one at the underside.
  • the plate lb is at the plate la fixed in an angle lb', and hinged in the direction stated as A around an axis lc in the plate la so that it can be opened and turned against the vertical pla ⁇ te la. This to make the equipment more compact when it is not used.
  • the three plates la, lb and Id include tracks 5 intended to receive test trenchers 2 which are inserted in those tracks 5.
  • Fig. 2 shows such a test trencher 2; it can e.g. be mad of cardboard.
  • the test trencher consists of two lateral edg which rake out 5a, and which fit into the tracks 5 at the dust sampling equipment 1.
  • the edges 5a also include a lock indentation in the end 2c and against the edge it is slight bended to make the installation easier.
  • a hole 2a going through the test trencher 2 has been made and it is covered by a test plate 3 consisting of a transparent an adhesive foil.
  • the adhesive surface on the foil 3 turns upside.
  • the foil can e.g. be quadratic and let into the back side of th test trencher 2, so that the back side of the foil is not scratched when it is inserted in the tracks 5.
  • the foil can also be let in between two layers in the trencher.
  • the lowest trencher holder Id is in tended to hold the so-called blind foil 2b which must be ke covered.
  • This blind foil will be described more thoroughly later on.
  • the metal straps 4 have no influence on the amount of dust which can be deposited at the test surfaces 3.
  • Fig. 3 shows how the equipment 1 can be placed at a per son 6.
  • the equipment can be attached to the person in sever ways, e.g. with a safety pin placed on the back side of the plates la and Id and hooked to the person's clothes or for the purpose placed at a porter's braces as shown in fig. 6.
  • This brace consists of a neck strap 7, which through a midd piece is connected with a lower breast strap 8.
  • the breast strap 8 can e.g. be hold tight by "limpet tape”.
  • the dust collector 1 can be secured to the middle piece with "limpet tape” and therefore the brace will be easy to remove.
  • the equipment 1 is placed on the middle of the breast of a person 6 , but it can be placed elsewhere on the breast as the equipment 1 is preferably placed as close to the person's mouth as possible to secure that the person can move comfortably.
  • Fig. 4 shows an alternative design where there, in con ⁇ nection with the trenchers 2, are used two protection straps 4.
  • the protection straps 4 make it possible to place a cover 9.
  • the dust sampling is ended it can be pushed down on the test surface 3, however, without touching this surface so that the test surface is not exposed to more dust, and so that the inside of the cover can be wedged around the side surfaces on that part which rake out lb.
  • This principal can be used in connection with all three trenchers 2.
  • Fig. 5 shows an alternative design for a test trencher e.g.
  • section 2d is a little wider than section 2.
  • the measurements can directly be spotchecked by usual a tive measuring equipment.
  • Measurements of the dust amount on the trenchers are do with known equipment which through screening of the trenche can measure the amount of dust according to the principle o the more dust, the less light will come through.
  • the same e quipment is also used for determining what level of referen the trenchers have before they are used.
  • the level of refe ⁇ rence is an indication for the amount of light coming throu the foil of the trencher or the same as no dust on the foil This reference value can be related to the reference number given to the test trencher.
  • the blind foil 2b constitutes, in relation to the meas rements, also a reference to be understand as that the foil is not exposed to dust since the front of the trencher is dust proof. Therefore, the trencher 2b only serves as reference ac ⁇ cording to other mechanical exposures which do not concern the dust depositing, and which have influence on the amount of light coming through the foil. This is due to the fact that when measuring the other three test trenchers special attention must be paid to a possible light penetration through the film 3 on the reference trencher 2b. Through me suring the three other test trenchers the changed light pen tration through the reference foil can be taken into ac ⁇ count, so that in defiance of mechanical exposures precise dust measuring can be made.

Abstract

L'invention concerne un dispositif de prélèvement de poussière léger (1) conçu pour recevoir la poussière en suspension dans l'air dans un environnement sélectionné. Ce dispositif qui doit être porté sur la poitrine d'une personne fonctionne sur le principe de prélèvement passif de poussières, c'est-à-dire de collecte de poussière sur une surface de réception. La poussière se dépose sur trois surfaces adhésives et transparentes (3), l'une tournée vers l'avant, l'autre vers le haut et la dernière vers le bas. Ce dispositif comprend également une surface de référence couverte (2b). La poussière en suspension dans l'air se dépose sur les surfaces de réception (3) sous l'effet des forces de diffusion turbulentes et de gravité. La poussière collectée sur les trois surfaces peut être mesurée par des équipements de mesures connus qui, par analyse des plaques d'échantillonnage, peuvent mesurer la quantité de poussière déposée. On peut ensuite additionner les résultats des mesures obtenus à partir desdites plaques (3) et obtenir un résultat très précis comparable à celui obtenu avec un équipement de mesure de la poussière nettement plus cher et complexe fonctionnant selon le principe de prélèvement actif de poussière.
