The Four Most Dangerous Types of Construction Accidents

On Behalf of | Nov 21, 2018 | Construction Law, Firm News

Workplace accidents are a risk of any job, but are particularly dangerous on construction sites, often leading to serious injuries or even death.

Construction sites are known to have some of the most dangerous hazards to workers. In fact, many in the construction industry refer to the most hazardous accidents as the fatal four.

The attorneys of Bowles & Verna LLP would like to take a moment to consider the four most dangerous types of construction accidents facing Oakland, CA construction workers.

What Are the Fatal Four Construction Accidents

The Occupational Safety and Health Administration (OSHA) defines the fatal four hazards at construction sites as falls, being struck by objects, caught-in or between objects, and electrocution.

According to OSHA, more than 20 percent of workplace deaths in 2016 were in construction. Of these deaths, the fatal four accounted for more than half.

OSHA also found that of the fatal four, falls are the deadliest and make up about 38.7 percent of deaths, followed by being struck by an object at 9.4 percent, electrocutions at 8.3 percent, and being caught between something at 7.3 percent.

Let’s take a closer look at these four most dangerous types of construction accidents.


Falls are one of the most dangerous types of accidents in construction sites, as well as the most common of the fatal four accidents. Falls are so dangerous on construction sites because they can occur from great heights or lead to landing on hard surfaces, such as concrete.

Any fall can lead to head injuries, broken bones, or even death. When a fall is from a scaffolding, ladder, roof, or other elevated structure, injuries are more likely to be severe and fatal.

Falls may occur in construction sites as a result of the negligence of co-workers, subcontractors, employers, or anyone on the site. Leaving a spill uncleaned, leaving cords unorganized and spread across walkways, and not having proper protective gear, like harnesses and personal fall arrest systems, can lead to falls and serious injuries.

Struck by an Object

Being struck by an object is another dangerous accident common to construction sites. Struck-by accidents refer to any accident in which a person was hit by an object. On a construction site, this may include objects falling off of scaffolds or beams, moving materials around construction sites, or a coworker losing grip of tools.

The severity of injuries caused by being struck by an object largely depends on the area of the body in which the object hit, the size of the object, and the force at which the object struck.

Being struck on the head by an object can cause a concussion or a traumatic brain injury. A blow to the body can cause bruising or internal damage to the organs. If the force is strong enough, it may lead to death.

Caught-in or Between

Getting caught in machinery or between two objects is another dangerous construction accident. Caught-in or between injuries include being crushed by collapsing structures, getting pinned between two objects, getting run over by equipment, or getting a limb stuck inside of machinery.

Crushing the tissues can cause the cells within the muscles to die; it can also cut off blood flow to the tissues. This often leads to serious injuries when parts of the body are caught in machinery or between objects.

Injuries may include:

  • Loss of limbs, either from being severed at the time of the accident or requiring amputation
  • Broken bones
  • Damage to the internal organs
  • Compartment syndrome from internal bleeding and tissue swelling
  • Death


Electrocution is a serious hazard on construction sites and can lead to permanent disability and death. Even a small amount of current can affect the heart, leading to a potentially fatal condition called fibrillation.

Electrocution can occur on construction sites as a result of worker negligence, human error, or defective machinery. Working around exposed electrical currents can result in electrocution if proper safety precautions are not followed.

Electrocution is often fatal but some people will survive. However, survivors of electrocution may suffer from permanent complications from the injuries, such as renal failure, brain damage, and cardiac arrhythmia.
