If purchased in powder form, a respirator should be considered. Below is a link to the Crystal Violet powder Bio Cert Grade SDS with respirator and glove thickness recommendations.
Hi All,
A biology faculty member asked me about indicators and stains. I thought I would present this question to the list and get your collective wisdom.
Does anyone have any experience with the hazards of indicators/stains in general, specifically crystal violet which has been recently identified as a potential carcinogen? What do you do? Are special handling methods needed for the solutions?
The SDSs identifies health problems with the solids for many of the indicators which suggest special handling is needed. However, for solutions, the hazards are given as either nonexistent or very low and only required usual PPE (gloves, eye protection, ventilation,
etc.). Crystal violet is of specific concern at the present moment.
The application is in a biology/microbiology lab. The indicators/stains arrive at the lab already as solutions, so their preparation is done by someone else - either purchased as solutions or prepared by the stockroom tech.
Thanks in advance!
