Q

The following general rules should be strictly
followed in the laboratory:

A

 Gloves must be worn when handling
biological specimens
 Areas or equipment used by personnel who
are not gloved should not be touched with
contaminated gloves
 Wash hands immediately if they become
contaminated, with or without gloves on
o Most important in handwashing:
mechanical hand rubbing
 Do not remove specimen tube stoppers until necessary
 Mouth pipetting is strictly prohibited
 Replace clay slabs for microhematocrit tube
sealing frequently
 Decontaminate sedimentation tube racks
regularly
 Unfixed or unstained slides should be
considered infectious
 Do not handle needles
 Obtain immediate treatment for accidental
and inappropriate contact with biohazards
 Properly dispose of contaminated laboratory
supplies
