Annual safety training, or any training for that matter, can sometimes be looked at as a nuisance, especially by experienced workers who may have seen the same old video year-in and year-out.
That’s why it’s imperative that those responsible for safety training vary the way in which they offer training so employees actually enjoy the time spent reviewing safety standards, rather than loathe it. For example, many people respond well to humor. Finding ways employees can relate to a subject matter will result in positive feedback and better retention of important safety information.
A popular training method is to use a game to keep people involved, rather than simply lecturing or talking at them. Game show formats, such as Jeopardy! or Wheel of Fortune, are popular especially when prizes are involved. A good safety training game is a scavenger hunt for safety hazards, which can be particularly effective with a large group of people who are being retrained on material they already know.
There are a number of resources for good, creative training ideas. Go to the Tools section of the Complete Guide to Laboratory Safety, Third Edition,  for a training program evaluation form so you can get feedback from your employees about your safety training.
