Using Photoelectric Smoke Detection to Warn of Pre-Ignition Conditions of Unattended Cooking Fires

Abstract

A series of experiments was conducted to examine the potential to use kitchen-installed photoelectric smoke detection devices to warn of approaching ignition of food during unattended cooking. An electric range, range hood, and cabinets were installed in a mock-up kitchen. Research smoke meters and standard off-the-shelf photoelectric smoke detectors were installed above the food, on the ceiling, and on the upper wall. In addition to smoke meter and smoke detector outputs, pan and food temperatures along with digital videos of the experiments were recorded. Cooking oils and bacon were heated to ignition. The standard threshold smoke detection devices not designed for kitchen use alarmed several minutes before ignition. Typically smoke production reached unacceptable levels at least 2 min before ignition. Standard hamburger tests were also conducted to compare smoke levels from attended, but smoky, cooking to the unattended cooking smoke. Analysis indicates that there is a useful time window of smoke obscuration thresholds above smoky attended cooking and sufficiently prior to ignition to allow warning that would either alert the cook to return and de-energize the range or to interface with an automatic de-energizing device interfaced with the range.
