Demolition work comes with several hazards that can lead to debilitating injuries or worse. That is why construction safety standards are also applicable on those sites. This includes safety standards for additional hazards which make demolition particularly hazardous.
That is why OSHA created special safety standards for this practice besides 29 CFR Part 1926 which are already applicable. The standards are quite extensive and can be found online but here are a few which stand out:
Preparatory operations make up most of the citations that are necessary for a demolition site. It requires a survey which needs to be completed before the event.
Walls or other masonry sections should not be allowed to fall on the floors of the building being demolished in quantities that can make the floor cave in.
Wall sections that are more than a story high should not be allowed to stand without proper bracing efforts in place unless it was designed to remain standing without support. All walls should remain stable at the end of each demolition shift.
No worker should be allowed to work on top of a wall in adverse weather conditions.
Openings in floors that are at least 10 feet away from a wall being demolished should be filled with planks which should be nailed down.
Any gaps cut into the floor for material disposal should not be larger than 25% of the total floor area until lateral supports are in place.
Floor areas that have been weakened due to demolition practices should be shored.
During construction or repair work, all debris such as extra nails and scrap should be stored clear from work areas in and around the work site.
All debris and scrap that is flammable should be removed regularly during construction and via safe means.
