If an accident occurs on the LDEO Campus the LDEO Safety office needs to be contacted to coordinate the correction action plan.  This includes accidents / injuries on duty to employees, students, visitors or vendors.  Send an email to and then call 845-359-2900.

  • All work-related injuries resulting in amputation, loss of an eye or in-patient hospitalization must be reported to LDEO Safety office immediately, as such accidents need to be reported to OSHA within 24 hours.

After an accident occurs, the injured person and his/her supervisor or host are to fill out an Accident Report (see link below).  The Accident Report must be filled out for ALL accidents, even if the affected person appears uninjured.  The supervisor or host must notify the Safety office ASAP, which will prompt an accident investigation.  A corrective action plan is to be negotiated with the Safety office in order to complete the accident report.  Upon completion, the report will be filed with HR and with the Safety office.  A Worker's Comp form notice is to be completed with HR at the same time if necessary.
