Protecting Pennsylvania Construction Workers: Understanding the OSHA Fatal Four

On Behalf of Douglas, Joseph & Olson Attorneys At Law  |

As a Pennsylvania construction worker, you may face some of the most dangerous conditions in any profession, conditions directly addressed by understanding the OSHA Fatal Four. The legal team at Douglas, Joseph & Olson Attorneys At Law often assists workers in the construction industry to pursue compensation to cover the costs of their damages caused by an accident.

Localizing the Risk: Fatalities in Pennsylvania

As a Pennsylvania construction worker, the hazards you face aren’t abstract—they show up in statewide data. In 2023, Pennsylvania recorded 169 workplace fatalities; falls, slips, and trips accounted for 43 (about one in four). The construction sector had the most deaths, with 30 fatalities, which is about 18% of the total. Specialty trade contractors, like roofers, electricians, and laborers, accounted for 17 of these deaths. In construction, falls caused 16 out of 30 deaths. This shows why fall protection should be a top priority on every job.

Pennsylvania workplaces are covered by federal OSHA; the Commonwealth supplements this with programs like certified workplace safety committees (which can earn employers a 5% workers’ comp premium discount). Vigilance, training, and strict adherence to requirements—especially fall protection and machine guarding—are essential to prevent life-altering injuries.

But what makes your job so dangerous? According to OSHA, there are four types of accidents that often kill construction workers. You can find more information about these accidents here. These are known as the OSHA Fatal Four.

The OSHA Fatal Four Statistics


Understanding the primary threats is the first step toward prevention. The following accidents comprise the OSHA Fatal Four and represent the leading causes of construction worker fatalities:

  1. Falls: You are most likely to be killed by falling; 384 workers died because of injuries suffered in a fall.
  2. Struck-By Object: There were 93 workers who died when an object on the job site struck them; while there were far fewer casualties than falls, it still presents a significant danger.
  3. Electrocution: Almost as many workers died from electrocution as from struck-by accidents; 82 suffered fatal electrical accidents.
  4. Caught-Between/Crushed: A close fourth among the OSHA Fatal Four, accidents that involved workers becoming caught, compressed, or crushed by machinery, equipment, or collapsing structures caused 72 deaths.

Connecting Violations to the Fatal Four

The law requires your employer to follow strict safety guidelines. OSHA inspects job sites and issues citations for noncompliance, and it is not too difficult to connect the most frequently cited violations to the most frequently occurring deadly accidents in the OSHA Fatal Four.

For example:

  • The most citations were issued for a lack of fall protection.
  • Other common citations relating to the OSHA Fatal Four included scaffolding violations and ladder safety violations.

Additionally, citations were issued for failing to meet safety standards regarding:

  • Electrical and wiring violations and lockout/tagout violations (addressing electrocution risks).
  • Machinery and machine guard regulations (addressing caught-between hazards).
  • Safety standards for powered industrial trucks.
