Article Abstract:
Warnings have an important role in ergonomics. They come in two forms, namely, visual warnings and auditory warnings. Warnings should be a supplement to safety procedures. Visual clutter is said to diminish the probability of people to act on warnings. Over-warning may become a problem. Auditory warnings may have problems in identification and recognizability than visual warnings. Findings from each of the papers in the issue are summarized.

Article Abstract:
Recent research on the design of warnings indicate that design variables influence the effectiveness of warning labels. A study is done where the signal word 'WARNING' is presented in red surrounded by a red border at the head of a black pesticide label using 8-point type. Twenty-four undergraduates were used in a study on signal-word font size. Another study using another 24 students compared red labels with labels in black.
