At What Height Do Falls Become Deadly?

Falls become potentially deadly at feet above ground level, or above the floor level, depending on variables. As a general rule of thumb here are some facts:

• For adults falling about 20 feet, or up to as high as two storeys, one can be killed.
• According to many safety and lifestyle analyses, there is consensus that falling from around 30 feet above ground level is almost always fatal.

While shorter falls (less than 10 feet) can still be more damaging, the ratio of those that prove to be lethal scales up very high once it passes the 20-30 foot range.

More facts about fatal falls

1. Data for Proving the Critical Height for Falls

• Experiments and statistics demonstrate that falls from over 26-30 feet high levels are deadly by over 50%.
• The construction industry designates a “Lethal Height” threshold of 48 feet, over which dangers that proceed to be fatal go over 90%.

2. Influence of Body Position and Landing

• Feet First as Opposed to Heading First: Falls whose landing was headfirst were far more deadly compared to the landing whose feet were first to touch the ground.
• Surface Impact: In cases where hard surfaces are involved, such as concrete or pavement, this could lead to greater susceptibility to causing danger resulting in a fatality. Whereas, falls onto softer surfaces, such as grass, or sand, could be less dangerous.

3. Survivability of Falls from Extreme

There have been very few cases of surviving a fall from above 100 feet under particular conditions like tree branches or awnings breaking the fall and such cases may be quoted to be far extreme exceptions.

4. Physiology of Humans and G-Force

The body’s ability to deal with this force of impact, often considered in the form of G-force, depends upon it. G forces generally over 75 Gs tend to be lethal levels of force and their generation in free-fall millitudes is beyond human survivability.

5. Laws and Safety Procedures

According to information gathered on injury risks, the OSHA standards for workers call for fall protection at elevations above 4 feet for general industries and 6 feet for construction.

6. Preventative Measures and Safety Gear

Emphasize the need for fall arrest systems, guardrails, and good footwear to reduce risks even below those elevations.

Factors that affect the impact of Falls

1. Distance of the Fall

Falls from heights greater than 20-30 feet (6-9 meters) are usually deadly. However, falls from lower heights can also be fatal if other circumstances such as the landing on the head or poor body position prevail.

2. Body position at impact

Tumbling or Rotational Falls: Falls that feature a tumbling core have uncontrolled forces of impact landing, which increases critical injury chances.

3. Point of Impact

It matters which point of the body makes contact with the surface because not only do the forces that reach the bony skeleton, joints, and intra-abdominal organs disproportionate to the injuries caused but also the manner and area of impact on the skull (for example) has a strong correlation to the level of potential damage to the brain.

4. General Health and Age of the Individual

Age: Older adults often suffer fatal falls since they have a lower bone density and slower reflexes

Coexistence of medical comorbid conditions: Patients with cardiac pathology, osteoporosis, or other systemic pathologies put the patient at higher risk of a fatal outcome

5. Reaction Time and Reflexes

Ideal reflexes may significantly reduce injury from the fall, as the individual will try and maneuver their body into a less vulnerable position, and in part, the fall may be broken by hands or feet.

6. Protective Equipment

In a few circumstances, a head that is properly protected approaches being almost immune to fatal brain injury, and harnesses and Fall Arrest Devices can help prevent the fall altogether, or, at worst, reduce its severity.

7. Environmental Conditions

Wind conditions may lead to an exposure loss of balance and may result in more frequent uncontrolled falls because of a greater loss of balance.

Secondary impacts are often caused by sharp edges, protrusions, and, in some instances, various types of barriers, which may increase the severity of injury.

8. Landing Conditions

Breaking the Fall: Impact force can be reduced with trees, awnings, or the construction element known as scaffolding if they will slow the descent; chances of survival can be increased.

Secondary Falls: Repeated tumbling after the initial impact can result in multiple traumas, thereby increasing the risk of fatality.

10 Practical steps to avoid deadly falls:

1. Strong rails at high levels, on platforms, over stairwells, and alongside elevated open areas, should be in place to offer tangible protection.

2. We should ensure maximum lighting in all areas, especially in stairwells, walkways, and entrances. This would provide clear visibility, giving minimal chances for tripping.

3. Keep walkways clear of clutter, cords, spills, and obstacles that a person could trip or slip on.
4. Install non-slip mats, tiles, or coatings in areas that may become wet or greasy, such as bathrooms, kitchens, and loading docks.
5. Encourage good footwear with traction in environments where the floors might be slick or uneven.
6. Educate staff or residents on areas with fall hazards, how to walk carefully, and instructions on the use of fall equipment
7. Ensure all staircases and ramps have safe handrails on both sides to give a firm grip. The handrail should provide supplementary support.
8. Ensure there is a frequent check on ladders, ramps, and safety equipment in use such as protective railings and adjust these things to desired performance.
9. Bundle electrical cords and wires together and secure them out of the paths of walkway areas to avoid any possible trip.
10. Utilize in high places of employment personal fall arrest systems, including harnesses and lanyards, safety nets, and guardrails, with attachment points at a high level, when safety regulations call for.
