Sometimes a new employee is like the old canary miners took with them. They alert you to bad air. Sometimes, after you have used a product for a while your body has adjusted to it and you cease to notice it.
We use xylene, the last time a substitute was looked at one of the techs had a reaction to it so we stayed with xylene. The lab is negative pressure, the air exchange rate is 52 times per hour and all the equipment that generates fumes is either in a large hood or directly vented into the fume system. We also test for xylene and formalin once a year which is a OSHA requirement and the main hoods are inspected and tested twice per year. We have done everything we can to keep our air fresh no matter what chemical or reagent we use. Bottom line: Not all people can work in a Histology lab plain and simple. If someone starts reactions to our reagents as per our guidelines they will be sent to Employee Health for review.

I realize that getting another job NOW is not easy, but redoing standardized procedures over and over could drive a lab into the ground and ALL of the techs in that lab could be searching for another job. It is a mistake to automatically assume that substitutes cannot be toxic or cause sensitivity themselves. Glen D.

Do you have any idea what would mean to that employee to try to get another job NOW? Changing the procedure is what we (as histotechnique refers to) have been doing for ever. Perhaps you do not remember other methods, but I do because I started working in this field in 1952. Back then I processed tissues manually and used aniline oil to "clear", benzene as ante medium and was very glad when I switched to white gasoline and later to xylene. Do you know why xylene became so prevalent? Because in 1943 the AutioTechnicon was developed and they recommended xylene as the way to go. That selection also was the choice of the VIP manufacturers, and we all started to change from the toxic benzene and aniline oil to the toxic xylene. There are other ways of doing things and changing work or exposing to toxic chemicals is not the correct path, no matter how much we are "used to".

The histo lab is filled with chemicals that can cause sensitivity in those people who may be prone to that. Unfortunately, some of the main players in the histo lab (xylene & formalin) are often the culprit, but they are the best products in terms of how well they work, how universally they are used, how well their characteristics are known, etc... I hate to sound like I'm not sympathetic, because I truly am, but I think it is a mistake to modify a histology lab's procedures to accomodate a new employee.
