Permits shall be required as set forth in rule 1301:7-7-01 of the Administrative Code.

Hot work shall only be conducted in areas designed or authorized for that purpose by the personnel responsible for a “Hot Work Program.” Hot work shall not be conducted in the following areas unless approval has been obtained from the fire code official:

(a) Areas where the sprinkler system is impaired.

(b) Areas where there exists the potential of an explosive atmosphere, such as locations where flammable gases, liquids or vapors are present.

(c) Areas with readily ignitable materials, such as storage of large quantities of bulk sulfur, baled paper, cotton, lint, dust or loose combustible materials.

(d) On board ships at dock or ships under construction or repair.

(e) At other locations as specified by the fire code official.

Compressed gas cylinders and fuel containers shall comply with this rule and rule 1301:7-7-30 of the Administrative Code.
An oxygen-fuel gas system with two or more manifolded cylinders of oxygen shall be in accordance with NFPA 51 as listed in rule 1301:7-7-47 of the Administrative Code.

The following words and terms shall, for the purposes of this rule and as used elsewhere in this code, have the meanings shown herein.

“Hot work.” Operations including cutting, welding, Thermit welding, brazing, soldering, grinding, thermal spraying, thawing pipe, installation of torch-applied roof systems or any other similar activity.

“Hot work area.” The area exposed to sparks, hot slag, radiant heat, or convective heat as a result of the hot work.

“Hot work equipment.” Electric or gas welding or cutting equipment used for hot work.

“Hot work permits.” Permits issued by the responsible manager at the facility under the hot work permit program permitting welding or other hot work to be done in locations referred to in paragraph (C)(3)(2603.3) of this rule and pre-permitted by the fire code official.

“Hot work program.” A permitted program, carried out by approved facilities-designated personnel, allowing them to oversee and issue permits for hot work conducted by their personnel or at their facility. The intent is to have trained, on-site, responsible personnel ensure that required hot work safety measures are taken to prevent fires and fire spread.

“Responsible manager.” A person trained in the safety and fire safety considerations concerned with hot work. Responsible for reviewing the sites prior to issuing permits as part of the hot work permit program and following up as the job progresses.

“Torch-applied roof system.” Bituminous roofing systems using membranes that are adhered by heating with a torch and melting asphalt back coating instead of mopping hot asphalt for adhesion.

Hot work conditions and operations shall comply with this rule.
Temporary and fixed hot work areas shall comply with this paragraph.
Hot work permits, issued by an approved responsible manager under a hot work program, shall be available for review by the fire code official at the time the work is conducted and for 48 hours after work is complete.
A permit for hot work operations shall not be issued unless the individuals in charge of performing such operations are capable of performing such operations safely. Demonstration of a working knowledge of the provisions of this rule shall constitute acceptable evidence of compliance with this requirement.
The individual responsible for the hot work area shall maintain "prework check" reports in accordance with paragraph (D)(3)(a)(2604.3.1) of this rule. Such reports shall be maintained on the premises for a minimum of 48 hours after work is complete.

Visible hazard identification signs shall be provided where required by rule 1301:7-7-27 of the Administrative Code. Where the hot work area is accessible to persons other than the operator of the hot work equipment, conspicuous signs shall be posted to warn others before they enter the hot work area. Such signs shall display the following warning:

“CAUTION

HOT WORK IN PROGRESS

STAY CLEAR”

Protection of combustibles shall be in accordance with paragraphs (D)(1)(a)(2604.1.1) to (D)(1)(i)(2604.1.9) of this rule.
Hot work areas shall not contain combustibles or shall be provided with appropriate shielding to prevent sparks, slag or heat from igniting exposed combustibles.
Openings or cracks in walls, floors, ducts or shafts within the hot work area shall be tightly covered to prevent the passage of sparks to adjacent combustible areas, or shielded by metal fire-resistant guards, or curtains shall be provided to prevent passage of sparks or slag.
Floors shall be kept clean within the hot work area.
Conveyor systems that are capable of carrying sparks to distant combustibles shall be shielded or shut down.
Partitions segregating hot work areas from other areas of the building shall be noncombustible. In fixed hot work areas, the partitions shall be securely connected to the floor such that no gap exists between the floor and the partition. Partitions shall prevent the passage of sparks, slag, and heat from the hot work area.
Fixed hot work areas shall have floors with noncombustible surfaces.
Hot work shall not be performed on containers or equipment that contains or has contained flammable liquids, gases or solids until the containers and equipment have been thoroughly cleaned, inerted or purged; except that “hot tapping” shall be allowed on tanks and pipe lines when such work is to be conducted by approved personnel.
Automatic sprinkler protection shall not be shut off while hot work is performed. Where hot work is performed close to automatic sprinklers, noncombustible barriers or damp cloth guards shall shield the individual sprinkler heads and shall be removed when the work is completed. If the work extends over several days, the shields shall be removed at the end of each workday. The fire code official shall approve hot work where sprinkler protection is impaired.
Approved special precautions shall be taken to avoid accidental operation of automatic fire detection systems.
Fire watches shall be established and conducted in accordance with paragraphs (D)(2)(a)(2604.2.1) to (D)(2)(f)(2604.2.6) of this rule.

A fire watch shall be provided during hot work activities and shall continue for a minimum of 30 minutes after the conclusion of the work. The fire code official, or the responsible manager under a hot work program, is authorized to extend the fire watch based on the hazards or work being performed.

Exception: Where the hot work area has no fire hazards or combustible exposures.
The fire watch shall include the entire hot work area. Hot work conducted in areas with vertical or horizontal fire exposures that are not observable by a single individual shall have additional personnel assigned to fire watches to ensure that exposed areas are monitored.
Individuals designated to fire watch duty shall have fire-extinguishing equipment readily available and shall be trained in the use of such equipment. Individuals assigned to fire watch duty shall be responsible for extinguishing spot fires and communicating an alarm.
The individuals responsible for performing the hot work and individuals responsible for providing the fire watch shall be trained in the use of portable fire extinguishers.
Where hoselines are required, they shall be connected, charged and ready for operation.
A minimum of one portable fire extinguisher complying with paragraph (F)(906) of rule 1301:7-7-09 of the Administrative Code and with a minimum 2-A:20-B:C rating shall be readily accessible within 30 feet (9144 mm) of the location where hot work is performed.
Before hot work is permitted and at least once per day while the permit is in effect, the area shall be inspected by the individual responsible for authorizing hot work operations to ensure that it is a fire safe area. Information shown on the permit shall be verified prior to signing the permit in accordance with rule 1301:7-7-01 of the Administrative Code.

A pre-hot-work check shall be conducted prior to work to ensure that all equipment is safe and hazards are recognized and protected. A report of the check shall be kept at the work site during the work and available upon request. The pre-hot-work check shall determine all of the following:

(i) Hot work equipment to be used shall be in satisfactory operating condition and in good repair.

(ii) Hot work site is clear of combustibles or combustibles are protected.

(iii) Exposed construction is of noncombustible materials or, if combustible, then protected.
