Chemical Vapor Monitoring Badges

Chemical & CAS Number Quick Reference Guide

Reviewing a Safety Data Sheet (SDS)? Use this guide to find the matching EMT vapor monitoring badge. Some entries are mixtures or groups of chemicals, and some offer both an individual chemical and an “all isomers” option. If your chemical isn’t listed, or you’re not sure which option you need, contact EMT and send your SDS. A CAS number is listed to help identify a chemical; each badge page shows the monitoring options EMT offers.
