R J Grondin & Sons · Struck by... (Not Elsewhere Classified)

Employee was welding on a grizzly and took EE's lunch break. EE believes when EE took EE's welding hood and glasses off to wipe EE's forehead EE may have pushed a foreign body into EE's eye. It did not bother EE until late afternoon. On Saturday EE went in and had it removed and was provided an ointment to prevent infection.
