Change Significance

This change correlates fire protection requirements for domestic cooking in alcohol and drug treatment centers, assisted living facilities, group homes, halfway houses, social rehabilitation facilities and similar occupancies (Group I-1) for more than 16 persons who live there on a 24-hour basis in a supervised environment and receive custodial care.

Occupants of these facilities are often capable of preparing small meals in cooking spaces less sophisticated than a full-scale commercial cooking operation. Even though a smaller scale, hazards still exist and those not involved with the cooking operation still need to be protected.

Section 904.13.1 provides an option, either provide a fire-extinguishing system or install a cooking appliance meeting specific heating limitations. Section 904.13.1.1 provides the criteria for design of an automatic fire-extinguishing system. The system must be designed and tested to UL 300A “Outline of Investigation for Extinguishing System Units for Residential Range Top Cooking Surfaces.” This standard is not equivalent to the UL 300 standard for commercial cooking facilities.

Option 2 is in Section 904.13.2. This section requires the cooktops and ranges to meet specific heating limitations. These cooking appliances have listed ignition-resistant burners that do not allow cooking oils to ignite during testing.

Recent work by the Fire Protection Research Foundation confirms that burners meeting these specifications are highly unlikely to ignite cooking materials. Their report can be found at: http://www.nfpa.org/research/fire-protection-research-foundation/reports-andproceedings/other-research-topics/analytical-modeling-of-pan-and-oil-heating-on-anelectric-coil-cooktop. UL 858, “Standard for Safety for Household Electric Ranges” was recently revised to include a new Section 60A that evaluates the ability of burners to not ignite cooking oil. Section 904.13.2 is shown as deleted, but it is only deleted from this section. The requirement for portable fire extinguishers near domestic cooking appliances is now found in Section 906.1, Item 2.
