Discussion

The range of pictograms shown in the table above gives a good hint of the diversity of variants and image contents available to indicate the location of or direction to a fire alarm call point or to identify a device that initiates a fire alarm and emits an acoustic and/or visual alarm and/or notification of fire. A few of these graphic symbols were developed as entries for the Icograda student project (Frascara). No single visual stereotype can be identified.

In the context of this Icograda student project and the ISO test series 1979/80 (Easterby & Graydon, 1981 a) five graphic symbols intended for the message Fire Alarm were examined using the Appropriateness Ranking method. The numbers 1) to 5) represent the final rank order of the symbols tested. Subsequently the best three - marked 1) to 3) in the table above - were tested for comprehension (Easterby & Graydon, 1981 b) on several continents. None of these variants reached an acceptable number of correct responses. Almost half of the participants did not respond at all regarding the pictogram labeled 3) and one quarter of the answers for this variant were wrong or 'Don't know'. With 63.0 % correct responses the variant marked 1) performed best.

ISO testing continued with an Appropriateness Ranking Test conducted in Sweden, where Gärling (1985) examined 18 variants for Fire Alarm: The pictogram variants showing flames in different contexts or presenting the word ALARM were ranked better than all other variants tested. Reference No 5014 from IEC 60417 with the official message Horn, electrical / electromechanical and the symbol showing a rectangle in outline with a circle inside, all lines very bold, were rated as least appropriate. These two were correctly identified by 16 % resp. 8 % of the respondents only in an earlier study reported by Collins & Pierman (1979), results confirming the rank order established.

In the subsequent ISO Comprehension Tests, conducted in Australia, Austria, Hungary, Japan, and the United Kingdom (Brugger 1987), the design marked with B) in the table above performed very well with about 87.2 % correct responses when applying lenient scoring. The variant marked A) reached somewhat lower scores, especially in Japan, probably because bells are not as common in Japan. Pictogram C) showing a hand pointing downwards towards a dot with flames on the right, performed less well with 66.8 % correct responses.

In research limited to safety signs mainly among blue collar industrial workers and regarding graphical symbols marked a) to c), (Collins et.al, 1982, Collins, 1983) not a single variant seemed to be well understood and elicited numerous wrong responses like Noise Area, Hearing Protection, Bells Ringing, School Zone, Church for variant a) and High Noise, Use Ear Protection, Bell, Grinding Wheel, Machine, Rotating Shaft, and Vibration upon Striking for b), while the most frequent answer for variant c) was Fire Phone.

Recommendations

Regarding the test results available we recommend using pictogram TS0811 Fire alarm call point, an improved version of pictogram F005: Fire Alarm Call Point from ISO 7010, a registered safety sign. This pictogram is easily comprehensable for most persons even if just presented in black and white.
