In construction, serious injuries are often associated with big, dramatic events. You may think of falls from height, structural collapses or major equipment failures. Yet a more ordinary hazard persists on job sites that can do just as serious damage.
Dropped objects are not rare or unpredictable events. These incidents are almost always preventable, but they continue to cause critical injuries and fatalities across the construction industry. When they occur, it often points to gaps in systems and leadership oversight rather than a single worker error.
Understand the Impact
Any object dropped from height, regardless of its size, can become lethal. A hand tool, phone or piece of hardware falling from several storeys strikes with forces comparable to vehicles or heavy equipment. Hard hats can reduce the severity of injury, but are not designed to absorb the energy generated by objects falling from heights.
A labourer in BC suffered permanent serious injuries in 2015 when a drill fell from 27 storeys. A worker above had set the drill down for a moment to adjust the metal plate he was installing. The tool was not tethered and the ground below was not cordoned off. The ground crew was given no warning of the hazard. The prime contractor failed to provide site-specific safe work procedures for working above or below others.
Industry incident data and investigations consistently show that dropped object injuries often occur during routine work, such as installing materials, moving between tasks or working from scaffolds. These are common activities on many sites, which means the hazard is often present above workers.
In 2020, a Vancouver worker was killed at a high-rise construction site when bundles of rigid insulation materials were blown off an upper deck in windy conditions. In 2024, a woman lost her life while working at another Vancouver site. A concrete mould being hoisted from one floor to another came loose and fell 26 storeys.
Near misses involving dropped tools or materials are far more common than reported injuries. From a leadership perspective, these near misses should be viewed as early warning signs. If they are ignored or accepted as normal, the next time it happens, someone could be seriously hurt.
Awareness Is Not Enough
Most construction companies are aware that dropped objects are dangerous. But awareness alone does not control risk. Incidents keep happening.
In 2025, there were 44 injury claims caused by falling objects in Saskatchewan construction. Those working in all types of trades were affected, with ages ranging from 19 to 58. Injuries included bruises, cuts, sprains, fractures, concussions and back pain.
The consequences of a dropped object incident extend well beyond the injury itself. These events frequently result in work stoppages, investigations, regulatory action and project delays. A single preventable incident can affect multiple projects and relationships. It impacts operational continuity, risk management and professional credibility.
Take a Leadership Role in Prevention
Your organization can successfully control dropped object risk with a proactive, structured approach. Identify dropped object risks during pre-construction and pre-task planning, particularly for work at height, lifting activities and tasks performed over active work areas.
Expectations for tool control, material storage and housekeeping at height should be clearly defined and standardized across projects. Invest in engineered controls rather than relying solely on worker behaviour. Establish tool tethering systems, storage solutions, toe boards, tool nets or debris netting, and exclusion zones as standard requirements.
Questions to ask during regular discussions:
- How are dropped object risks identified and controlled during planning?
- What standards exist for tool control and material storage at height?
- How are exclusion zones established and enforced?
- How are near misses reported, tracked and addressed?
Integrate dropped object prevention with existing fall protection, lifting and work planning systems. This should include:
- Clear roles and responsibilities,
- Inspection and maintenance requirements for tools and attachments,
- Training expectations for work at height, and
- Consistent supervision standards.
Expect supervisors to verify that controls are in place and functioning before work begins. If a near miss occurs, take it seriously. Focus on learning and system improvement, not blame.
Stop the Drop
Dropped object incidents are not inevitable. Think of preventing dropped objects as an opportunity to demonstrate leadership, protect workers and reduce business risk. By addressing this hazard at the system level, you can ensure that everyday tools and materials never become life-altering hazards for your workforce.
