Abstract. Cooking activity is accompanied with several risks, mainly for elderly peo-
ple due to attention and memory impairment. Literature reveals that the kitchen is
the second most common place for domestic accidents. We argue that enhancing
safety during cooking activities could be achieved via designing a cooking-safe envi-
ronment based on insightful risk analysis and assessment study. This paper presents
our study on risk analysis and assessment during cooking, in order to build a cook-
ing-safe environment. The study is based on theoretical and real-world experimenta-
tions. Risk analysis and assessment enabled us to determine the three major risks
(i.e., ﬁre, burn and intoxication by gas/smoke) and the pertinent parameters to quan-
tify these risks. The results reveal that the pertinent parameters are: concentrations of
volatile organic compounds, alcohol, and carbon monoxide gases in the cooking
smoke, utensil temperature, burner temperature, relative humidity, and presence of a
utensil on burner. We present in details our study on risk analysis and assessment,
including the methodology and the ﬁndings.

People are subjected to several risks while performing indoor or outdoor activities
of daily living (ADL) [1–3]. Cooking is an important daily activity, however cook-
ing requires people to be very careful.
Studies revealed that the kitchen is the second most common place for domestic
accidents [4, 5]. Unattended cooking is the main leading factor responsible for ﬁre
in the kitchen [4, 6, 7]. Therefore, enabling safety during cooking is an important
goal to achieve. The three major risks during cooking are: ﬁre, burn (by contact
or splash), and intoxication (by gas or smoke) [8–10].
A basic existing solution to handle ﬁre risk at home is installing ﬁre alarms.
The main concern of ﬁre alarms is to detect ﬁre occurrence quickly, so ﬁre rescue
agents can intervene in time. However, existing ﬁre alarms have several draw-
backs, because people usually forget replacing alarm batteries regularly. In addi-
tion, ﬁre alarms generate false alarms (e.g., in the presence of a small quantity of
