How Should a Lab Safety Audit be Conducted?

November 25, 2014 5:02 am | by Vince McLeod, CIH | Comments

This apparently innocent question may be the one you agonize over the most. Personally, we feel there is no substitute for face to face interviews and a physical walk through of each laboratory.

Far too often, people use a high compression setting, on digital cameras and flatbed scanners or in software used to make images smaller (in size), to either store more images on memory cards or to download or email images faster. Unfortunately, what many people don’t realize is that JPG (also known as JPEG, short for "Joint Photographic Experts Group") compression discards real pixel values.
