The following are general guidelines to aid the Incident Safety Officer
in establishing PPE levels. The majority of deployment tasks will
take place in Level D or modified Level D.
The EPA Modified Level D protection scheme consists of the following

Leather, steel-toed work boots (with chemical resistant
overboots as necessary) or chemical-resistant, steel-toed boots meeting
