Is online-only CPR certification valid for OSHA?

No. In a 2012 letter of interpretation, OSHA said online training alone doesn't meet the first aid and CPR training in rules like 1910.151 and 1910.269, since CPR is a physical skill that has to be practiced. The Red Cross says its online-only course doesn't meet OSHA workplace requirements. Blended courses that end with an in-person skills session do.
