Every pathology department and associated histology laboratory must have a chemical monitoring program. It may be part of a larger Chemical Hygiene Plan. Laboratory employees must be kept safe by providing information on dangers, explaining the ways in which employees can protect themselves, and providing annual training to reinforce this information. This is not just a good plan – in most instances, this plan is backed by laws and regulations. This current blog will continue the ideas of the previous one, where we discussed engineering controls such as grossing hoods used in laboratories to provide safe work stations.
Chemicals / Chemistry
The dyes used in histology are chemical dyes that react in accordance with the basic rules of chemistry. Whether you are performing a routine hematoxylin and eosin (H&E) stain, or a special stain for fungi, the staining methods are based on underlying chemical principles.
In order to be a competent histologist that has the ability to troubleshoot processing and staining issues in the histology laboratory, you must have a basic understanding of how atoms and molecules bind together and react.
