2. Use a Pictogram.
Explain the hazard directly and simply.
Many people cannot read above a 6th grade level. Avoid "
" such as "Moving head can be dangerous" or “Use guard as needed".
Avoid adverbs, such as "quickly" or "sometimes" or "carefully". Be specific, instead. Exact instructions mean a safer environment.
Flush left text is more legible, especially for longer messages.
A pictogram symbol conveys, at a glance to even those that do not
read English well, the particular danger or the avoidance procedure. Professional pictograms
show that the hazard is serious.
