Trench and excavation accidents: What should workers know?

On Behalf of | Dec 19, 2025 | Firm News

Trench collapses and excavation accidents are some of the most dangerous events on a construction site. They often happen without warning and can cause severe injuries. In Connecticut, workers face these risks on road projects, utility repairs and building sites. Understanding safety rules and your legal rights can help you stay safe.

Why trench collapses happen

A trench collapse occurs when the walls of a hole give way, trapping workers inside. Soil is very heavy. Even a shallow collapse can crush a person in seconds. These accidents often happen when crews do not use “shoring” (supports) or “sloping” (cutting the walls at an angle).

Water also makes the ground weak. Rain, snow or leaking pipes can cause sudden cave-ins. Also, heavy machines parked too close to the edge add pressure and cause walls to fail.

In Connecticut, safety rules depend on who you work for. Federal OSHA covers private-sector workers. CONN-OSHA covers state and local government workers. Both require protective systems for trenches five feet or deeper. Even for shallower trenches, a “competent person” on-site must check for danger and use protective measures if the soil is unstable.

Common injuries and legal protections

These accidents can cause broken bones, brain injuries or trouble breathing. If you are hurt on the job, you may qualify for workers’ compensation.

Under Conn. Gen. Stat. § 31-284, the law uses a “no-fault” system. This means you usually do not have to prove the employer did something wrong. However, insurers can deny benefits if willful misconduct caused the injury or if drugs or alcohol played a role.

If you qualify, you can receive medical care and wage replacement. According to Conn. Gen. Stat. § 31-307, this equals about 75% of your average weekly take-home pay.

Sometimes, a third party, such as a machine manufacturer or another contractor, causes the accident. In those cases, you might have a separate legal claim, and you generally have two years to file these types of claims.

Next steps to take

A trench accident can change your life in seconds. After an injury, your focus should stay on safety, medical care and income support. Knowing your rights helps you avoid mistakes that can cost benefits. It also enables you to see when another party may share fault. Speaking with an attorney can guide you through claims and deadlines. This support can help you secure the full benefits you deserve.
