									MINNESOTA INTERNATIONAL FIRE CODE Application to Schools
March, 2003 CODE SECTION:
102.1

ITEM/TOPIC:
Applicability – Construction and design provisions

DESCRIPTION:
Construction & design provisions apply to:  Buildings and conditions following code adoption,  Buildings and conditions not legally in existence (i.e. did not comply with previous code),  Buildings and conditions specifically identified in sections of the code,  Buildings and conditions that represent a “distinct hazard”. Applies to both new and existing conditions. All provisions of the code that are not construction or design-related apply retroactively. Allows code official to issue and enforce “stop work orders” when work conditions are dangerous or unsafe.

COMMENTS:
Wording is similar to previous fire code. Previous codes had some limited construction provisions in Appendix I-A. All other provisions required a “distinct hazard” determination by the fire chief.

102.2

Applicability – Administrative, operational, & maintenance Stop Work Orders

Previous codes required a “distinct hazard” determination by the fire chief. Use only in circumstances that are an imminent hazard (i.e. cutting/welding with no fire watch, severe overcrowding, open flames not in compliance with code, etc.).
