Top 10 Reasons why dropped objects happen when working at height

Posted by Julian on 13 April 2016

In order to stop dropped and falling objects when working at height, an understanding of the primary causes of the incidents can help conduct more thorough risk assessments and avoid overlooking some fundamental reasons why drops happen.

Here are the top 10 causes of falling or dropped objects in the workplace:

1. Inadequate Risk Assessment

Failure to identify dropped object hazards. 

It is important to identify potential hazards as this can dramatically reduce the risk of an incident occurring if appropriate measure are taken. A risk assessment can identify potential energy sources, index tools and equipment required for each task and increase worker awareness about the potential dangers of falling objects.

2. Human Factors

Operator error, poor behaviour, complacency, neglect.

Inadequate training or awareness of hazards, operator error, complacency, neglect and poor reporting can result in compromised safety. Tool tethering toolbox talks, workshops and training give an outline of falling object hazards and help create a more competent, safety-conscious workforce.

3. Inadequately Stored or Secured Tools and Equipment

No tool lanyards or tethers being used. No containment of loose items.

Hand tools, power tools, mobile phones, even Personal Protective Equipment (PPE) are all examples of equipment and tools that should be securely tethered with tool lanyards to prevent them becoming falling objects.

4. Inadequate Procedures

Bad planning, no management of change.

As with risk assessments, if management of change process isn’t in place to identify and control risk from the changes occurring in the workplace, unidentified and new risks may be missed.

5. Failed Fixtures and Fittings

Corrosion, vibration, poor design, selection or improper installation.

Corrosion, vibration, poor design, selection or improper installation of fixtures and fittings can lead to failure. Failed fixtures and fittings can and will often dislodge and fall. Regular inspection helps monitor any deterioration so that appropriate measures can be taken.

6. Poor Housekeeping

Pre-existing hazards from previous tasks.

Workplaces and tool kits should be kept organised and tidy. Loose tools and equipment left around pose an unexpected risk to other workers. NLG have a number of systems to support and encourage best practice tool safety procedures, so that the user is alerted to any missing tools before leaving their work zone.

7. Collisions and Snagging

Lifting, travelling equipment, tag lines, service loops.

Moving equipment, lifting and tag lines can all cause snagging or collision. Impact from collisions can cause breakage or create other dropped objects and debris.

8. Inadequate Inspection, Repair and Maintenance

Ignoring unsafe conditions.

Regular inspections and maintenance repair schedules can help identify corrosion, damages, wear and tear to equipment and structural elements before they become a falling object risk.

9. Redundant, Neglected and Home-made Tools and Equipment

These should be eliminated.

Home-made tools, improvised tool tethers, equipment that is uncertified, or even damaged tools that have been subjected to a previous fall can fail or break unexpectedly. Tools, equipment and tethering gear should always be inspected before use.

10. Environmental Factors

Wind, sea motion, ice, snow, extreme conditions.

Wind, rain, snow, sea motion, mud, heat and sand can all change work conditions. These effects of these elements is more pronounced in exposed ares, like working at height, oil rigs and mines and can compromise stability of equipment, tools and structural features.
