This Workplace Health & Safety Poster is a reminder to workers to not trust what looks safe - because looks can be deceptive. It is only "safe" when it has been checked and tested to be so. This vital truth applies to all areas of health and safety including Pre-Start, Take 5, JSA, LOTO, Work at Height, and Confined Spaces etc.
