I have attended numerous webinars from PATHS and would give all of them 5-star ratings for content, practical utility, and ease of understanding. You do not need to be a Pennsylvania employer to attend.
Topics include ergonomics, lockout-tagout, fall protection (a major source of OSHA violations), workplace safety committees, safety planning, and more. The calendar is available here: http://events.r20.constantcontact.com/calendar/monthview?eso=001VLrPhPNwI4H0hWw80KrwXg&llr=t7pik9jab
