WCB-2026-0484 Claims Records 7 . oS oY to VRY gi Sh R. PY ee a Ly Uv To: Heather Gillis, Occupational Audiologist From: Anne Jopling, OHO Date: October 30, 1992 . . a 8.22 Subject: Claims Investigation - Following your request of September 21, 1992, I conducted a noise survey at Vancouver General Hospital for the purpose of obtaining noise level readings during the operation of a Digital Decwriter LA 120 printer. Results were as follows: Reading Location Result 1 face of printer 73-74 dBA 2 four feet from printer 70-71 dBA (typical working distance) 3 background noise (computer 71-72 dBA processing room) During this noise survey the printer of interest was located in a central computer processing area, therefore the background noise sources were likely higher than those present in the claimants work area. Asa result , readings | and 2 may be somewhat elevated from those experienced by this claimant during the routine use of this printer. As you can see, the levels measured support your earlier conclusion which stated that computer printers emit noise in the low to mid-70 dB range. These levels are well below the maximum permissible concentrations outlined in the Industrial Health and SAfety Regulation 13.21(3). If you require furhter information regarding this survey please call me at local 5692. 8.22 Anne M. Jopling, CIH, ROH Occupational Hygiene Officer Field Services Department Page 34 of 34
