Checking wrapped trays and instruments

Hello all ! At my hospital most of the instrument trays come from sterile processing wrapped in two layers of heavy blue paper . (I hope most of you are familiar with this method). Even if your facility uses metal trays for full instrument sets, every hospital I have worked at uses this blue paper to wrap individual items that do not go into peel packs such as mallets and large retractors . My question is this : after you remove the wrapper do you examine it for holes? Do you hold it up and look for light coming through that would indicate a cut or hole? Our new policy is that nothing can be put on the backtable until the covering is checked. I have always examined all packs to ensure they are intact before opening and would like to know how it is done at your hospital. Thanks : )
