EE#1 was carrying two 2x12 (10ft long) wood boards down the TK stairs. As the employee stepped down onto the ground, EE rolled EE's left ankle. EE#2, who was on the ground nearby, assisted EE#1 in getting up and seated on the walking pad of the TK. EE#3 then brought EE#1 to the employee lunchroom and they applied ice to the ankle.
