Directing safety is not enough

Safety procedures, safety talks, signs and other instructions direct workers. But attempting to identify all behaviors needed to keep employees safe fail in the midst of a changing work environment of aging equipment, cost-cutting, and changes in processes and people.
We also get complacent around these practices.
However, when peers are observing and giving feedback they are constantly looking for new hazards and at-risk behaviors, even those not listed in policy manuals, and having conversations about threats to safety.
Yes, direct the behavior you want to see; this is necessary but far from sufficient.
