NIOSH Pocket Guide to Chemical
Exposure limits, Respirator Recommendations, First Aid, more...
The Pocket Guide is a source of general industrial hygiene information on several hundred chemicals/classes found in the work environment. Key data provided for each chemical/substance includes name (including synonyms/trade names), structure/formula, CAS/RTECS Numbers, DOT ID, conversion factors, exposure limits, IDLH, chemical and physical properties, measurement methods, personal protection, respirator recommendations, symptoms, and first aid.
- Chromium(II) compounds (as Cr)
- Chromium(III) compounds (as Cr)
- Chromium Metal (CAS No. 7440-47-3)
- Chromic acid and chromates (CAS No. 1333-82-0)
International Chemical Safety Cards
An ICSC summarizes essential health and safety information on chemicals for their use at the "shop floor" level by workers and employers in factories, agriculture, construction and other work places.
- Chromium (III) chloride (anhydrous)
- Chromium (III) chloride Hexahydrate
- Chromium dioxide
- Chromium (III) hydroxide hydrate
- Chromium hydroxide sulfate
- Chromium (III) nitrate nonahydrate
- Chromium (III) oxide
- Chromium (VI) oxide
Documentation for Immediately Dangerous to Life or Health Concentrations
The IDLH documents the criteria and information sources that have been used by NIOSH to determine immediately dangerous to life or health concentrations.
- Chromium(II) compounds [as Cr(II)]
- Chromium(III) compounds [as Cr(III)]
- Chromium metal (as Cr)
- Chromic acid and Chromates
NIOSH Manual of Analytical Methods (NMAM)
NMAM is a collection of methods for sampling and analysis of contaminants in workplace air, and in the blood and urine of workers who are occupationally exposed.

Health Hazard Evaluations
NIOSH conducts Health Hazard Evaluations (HHEs) to find out whether there are health hazards to employees caused by exposures or conditions in the workplace.
Some recent HHE reports related to Chromium have been listed below. For a comprehensive listing of HHE reports please search the HHE Database.
