First day on the job; 11,000-pound excavator kills operator
In September 2022, OSHA issued an employer $1.2 million in fines for willfully exposing workers to hazards at a jobsite that resulted in a fatality. Lack of hazard recognition, training, and safety planning contributed to the incident. The operator and his 11,000-pound excavator fell 80 feet. When the floor collapsed, the excavator was on a partially demolished multi-story garage bay floor.
OSHA’s investigation concluded the following:
- Heavy equipment shouldn’t have been operating on the partially demolished floors,
- Workers didn’t follow the demolition safety plan,
- The floor was overloaded and collapsed, and
- Jobsite training wasn’t adequate for workers to recognize hazards.
In the OSHA News Release, the Agency’s Regional Administrator stated the employer “knew the heavy equipment on the partially demolished floors were over the weight limits and still allowed a worker, unaware of the hazards, to do demolition work.” Employers must:
- Train workers to recognize hazards,
- Ensure a competent person inspects the jobsite for hazards, and
- Follow the jobsite’s safety plan.
This in-depth article addresses these safety issues, providing best practice tips to apply at your jobsite so you can avoid a similar incident.
Competent person
The term competent person often comes up in the OSHA construction regulations. OSHA defines a competent person as one who can identify existing and predictable hazards in the surroundings or working conditions that are unsanitary, hazardous, or dangerous to employees and who has the authorization to take prompt corrective measures to eliminate them.
OSHA’s 1910 and 1926 regulations require that a competent person inspect various work areas, and employers must train workers to avoid the identified hazards. In the above incident, an engineering firm developed the demolition plan, highlighting that placing heavy equipment on partially demolished floors was unsafe. The company should have followed the demolition plan and trained workers about unsafe loading.
Assessing the jobsite
Every employer must assess the jobsite for hazards. Other examples of heavy equipment or vehicle hazards a competent person might identify at the construction jobsite include:
- An excavator operating near a trench could cause overloading and stress cracks at or near the edge of the trench. In the abovementioned incident, the partially demolished floor was overloaded from the excavator’s weight.
- A sudden downpour could fill the trench or cause rain-soaked soil to give way. Inclement weather can cause water to accumulate and increase the likelihood of slips or the risks of an excavation or structure being demolished to collapse by the weight of vehicles or heavy equipment driven nearby.
- Accidentally striking an underground utility line with an excavator could present an immediate electrocution or hazardous atmosphere hazard. Workers need to verify the location of utilities before digging with mechanized equipment.
These are just a few incidents that could happen suddenly, requiring immediate attention and decision-making. That’s why the OSHA rules require employers to:
- Train workers to recognize and avoid unsafe conditions,
- Apply OSHA’s safety requirements to their work environment, and
- Control or eliminate hazards or workers’ exposures to illness or injury.
The following section discusses other training best practices to apply at your jobsite.
Training
The proposed penalty for the lack of training in this incident was $145,027. Perform annual refresher training and periodic evaluations to ensure operators have the knowledge and skills to operate heavy equipment safely. At a minimum, refresher training should occur when:
- Unsafe operations are observed,
- An accident or near-miss has occurred,
- An evaluation reveals unsafe operation,
- The operator will operate unfamiliar equipment, or
- Workplace conditions change that could affect the safe operation of heavy equipment.
The above incident’s operator should have been trained about changing jobsite conditions. The partially demolished garage bay had a reduced floor load rating.
The excavator he was operating shouldn’t have been allowed on the partially demolished floor. It was the operator’s first day at the jobsite. Had a competent person identified this hazard to the operator, trained him properly, and enforced the demolition safety plan, the incident could have been avoided.
Key to remember
Employers must ensure workers are trained to recognize hazards, a competent person inspects the jobsite for hazards, and the jobsite’s safety plan is followed.
