A permit is required to conduct hot work using oxygen and a flammable gas, such as acetylene or propane.
There may be additional fees associated with storage of cylinders utilized for hot work operations as well. Inspection unit will review such fees at time of inspection.
For construction sites, expiration will coincide with the Department of Buildings (or Authority Having Jurisdiction) work permit expiration date.
For site-specific operations, such as repair garages or metal fabrication, permit length is 1 year.
Citywide permits are for 1 year, but require the permit holder to conduct hot work operations at any individual location so long as such operation does not exceed 30 calendar days and all hazardous materials associated with such activity are removed from the location at the end of the workday.
