Positive Intervention - The Contractor's supervisor was on a ladder pop rivetting metal sheeting to the steel frame of a shed like structure. To get a better angle the supervisor attempted to climb onto the roof of the structure. The AECOM site supervisor and myself (on site for an SMO) immediately noticed the actions. The AECOM site supervisor asked the contractor to get back on the ladder which he did. He was then informed that he should rather move the ladder to the other side of the structure to gain the correct angle.
