The present research investigates how statement contents of consumer product warnings influence users' hazard perceptions. A number of researchers have found that the presence of warnings on products increased users' perceived hazardousness of the products，and that users perceived the products with high injury severity warnings to be more hazardous than those with low injury severity warnings. Other research，however，has shown that the presence of warnings did not increase users' perceived hazardousness，because they already viewed the products to be hazardous at a specific level even if they did not read warnings. There is，therefore，a lack of consistency in the results of the many studies carried out concerning this issue. The aim of this research was to examine the effects that explicitness and likelihood of injury have on user's ratings，such as perceived hazardousness，perceived severity and likelihood of injury. An experiment was conducted where 70 subjects were asked to rate a set of measures after each of them read one of five different warning labels in which the explicitness and likelihood of injuries were manipulated. The results indicate that the explicitness of hazards and injuries had an effect on the perceived severity of injury，but little effect on the other measures including the perceived hazardousness of the products. Also，the type of product presented in the experiment was found to be the most important factor in influencing any measure. This suggests that how hazardous users perceive products to be is based on the most hazardous experience that they have ever had with each product. Implications of the findings are discussed.
