201715 Open manhole hazard

 

As edited from Marine Safety Forum Safety Alert 16-17

During vessel loading, a shoreside foreman was walking on deck where other maintenance activities were taking place. As he made his way on deck the foreman inadvertently stepped into an open manhole. He was able to catch himself and prevent a free fall of 5 metres into the tank. The victim suffered a laceration on his shin, which required three stitches, and some bruising on his forearm.  

Lessons learned
- Once opened, a manhole should be cordoned off to provide protection and warning concerning the hazard.  
- When a variety of activities are going on simultaneously that involve different work teams the risks are increased. Coordination and toolbox meetings before starting the work can help mitigate these risks.
