Demo dangers
Knowledge is the key to staying safe during demolition
The bottom line: An investigation determined the contractor did not consult with the engineer who designed the structural support system, and therefore was unaware the changes made were not compatible with the demolition plan. The investigation also determined the boards were of an unusual size, unmarked and securely fastened, so the victim could have concluded the lumber was an architectural detail that could safely be removed.
Know what you’re getting into – When performing demolition on a structure, it’s crucial to have access to the building’s design plans before beginning work. Your employer will have a demolition plan on hand; make sure the actions you are performing are compatible with the plan.
Note inconsistencies – If you see something you don’t expect on the site – in the decedent’s case, it was wood affixed to the edge of a masonry wall – don’t try to figure out the situation yourself. Although any temporary shoring system should be approved and marked, don’t assume it always will be. Contact the foreman or call the office before you do something that can’t be undone.
Overcommunicate – In this accident, employees were concerned enough about the vibration from the railroad tracks to put in the support system. However, that information never got to the victim, who viewed the lumber as a fire hazard. Ask to see the job order form the general contractor to verify the work actually to be performed and to confirm you’re taking the appropriate course of action. EW
