There is no "right" number of safety meetings an organization should hold.
I would generally recommend holding at least one safety meeting a week, but your organization should pay attention to internal factors and ultimately decide for itself based on those.
If you find that your organization is encountering a high inciden
t rate, for instance, increasing the frequency of safety meetings can boost your workers' hazard awareness and vigilance on the job site.
With regards to safety meetings, the only question you should be asking yourself is "Will this meeting decrease the likelihood of an injury or incident?" If the answer is "Yes," then it's probably a good idea to host that meeting (learn about 6 Ways Regular Safety Meetings Decrease Incidents and Keep Employees Safe).
Remember, any production time that is lost on a safety meeting is far outweighed by the savings that come from decreasing incidents.
