MassGIS Data: Department of Fire Services HazMat Districts

April 2022

This layer represents DFS HazMat districts.

Table of Contents



The MA HazMat Districts were created by the Department of Fire Services organized under the Executive Office of Public Safety, and overseen by the State Fire Marshal. The 6 divisions are strategically located to be able to respond anywhere in the state within 1 hour. The HazMat teams assigned to each district support the local fire departments with technical information, expertise and specialized equipment. The district layer was created by coding each town with numbers 1-6 and then dissolving the town boundaries.

This layer is stored in ArcSDE and distributed as DFS_HMD_POLY.

Updated in August 2021 to be based on the Survey Towns Boundaries (previously based on the USGS-based town boundaries).


The polygon attribute table contains the following field:
