Chromium Reagents H2CrO4, CrO3, PCC, PDC, CrO2Cl2 Finding alternatives is highly encouraged! Inhalation  breathing difficulties, gastrointestinal and neurological effects
Dermal exposure  skin burns
Cr(VI) is more toxic than Cr(III)
Cr(VI) is carcinogenic lung cancer upon inhalation
3 – 4 mg could be fatal!<br>

Handling Cr compounds Use Cr compounds only after proper training and approval by your PI
Use only in well-ventilated fume hoods
Use cotton lab coat, gloves, face mask and goggles

Store separately from oxidizers, strong acids and bases<br>
03
Spills, Waste & Clean-up Have a separate, designated Cr waste bottle(s)
Dispose contaminated gloves/clothing/paper towels in appropriate Cr waste containers
Contain spills inside hood with sand/vermiculite
