Wogalter, Michael S., Magurno, Amy B., Carter, Ann W., Swindell, Julie A., Vigilante, William J. and Daurity, Jason G. (1995): Hazard Associations of Warning Header Components. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 979-983.

There has been relatively little warnings research directed at systematically examining the component features comprising existing warning signs as specified in standards (ANSI Z535) and guidelines (e.g., FMC, 1985; Westinghouse, 1981). This research examines several elemental features found in real-world warning signs to determine their individual as well as their combined effects on people's hazard perceptions. Various colors, signal words, shapes and configurations -- both individually and in combination-comprising existing warning headers as well as newly developed constituents were evaluated in a series of rating and ranking tasks. The results confirmed several existing published recommendations (e.g., the color red is perceived to connote more hazard than other solid colors), but also showed instances where people's perceptions differed from those assumed in design standards and guidelines. Some newly-developed header configurations (e.g., having a skull icon to the right of the signal world) show promise as alternatives for signaling hazardous conditions.

Wogalter, Michael S., Kalsher, Michael J., Glover, Barbara L., Magurno, Amy B., Fisher, Jake T. and Dunham, Daniel L. (1994): Increasing the Correct Connection of Automobile Battery Jumper Cables with an Enhanced Warning. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. p. 979.

Every year people are injured while improperly "jump starting" automobiles using battery booster cables. A common scenario leading to injury occurs when people attach both negative leads to the battery terminals instead of properly grounding the negative lead of the "dead" battery to that vehicle's engine block. An incorrect configuration can cause the "dead" battery to explode, discharging strong sulfuric acid. Two experiments examined the effectiveness of pictorial-based tag warnings illustrating the proper connection of jumper cables and the hazards associated with improper connection. Experiment 1 used pictures of cars with open hoods. When the warning was present, participants were significantly more likely to draw the correct connection sequence than when the warning was absent. Experiment 2 used actual booster cables to connect two realistic appearing mock batteries in adjacently parked vehicles. When an enhanced warning was present on the cables, participants were significantly more likely to accurately connect the batteries compared to an unenhanced (a current manufacturer's) warning or no warning. The present research shows that well-designed pictorial warnings can modify inaccurate beliefs and behavior concerning proper jumper cable connection.
