Safety Data Sheets, or “SDSs” are documents that summarize relevant safety information on a chemical. The old name, “Material Safety Data Sheet” is obsolete.
The database contains hundreds of thousands of vendor/manufacturer SDSs, updated frequently, plus many “Gold” SDSs written by ChemWatch toxicologists. You should review both any manufacturer SDSs as well as the Gold SDS for the chemical you are using.
If ChemWatch does not have the SDS you need, contact the Department of Health, Safety, and Environment to request a SDS. If you are not provided with a SDS upon request to your supervisor, by law you do not have to (and should not) work with that chemical.
You must access ChemWatch from a JHU IP address. If you receive a login prompt, do not try to login with your JHED ID. Connect to the campus virtual private network (VPN) using Junos Pulse and retry.
