Roofer's Family Member Helping at Work Site Dies After Falling Through Skylight |
| |||||||||||
SummaryA 19-year-old family member of a self-employed roofing contractor died when he fell through a skylight to a concrete floor 35 feet below. The victim was assisting the roofer repair water leaks on the flat roof of a commercial warehouse. The incident occurred at the completion of the two-day project. The victim was walking backwards to roll up a torch hose when he apparently tripped or stepped into the skylight. The acrylic plastic domed skylight shattered under his weight and the victim fell approximately 35 feet to the concrete floor. The victim’s father immediately called for assistance and notified emergency services. The victim was transported to a local emergency room where he died a short time later. The OR FACE team was notified by local news media reports on January 28, 2003. Contact was made with both the building owner and the roofing contractor. The roofing contractor was interviewed by phone. The building owner declined an onsite investigation of the incident scene. The OR FACE investigator visited the street location without accessing the building or the roof (incident location), on February 5, 2003. This report is based on the interview with the employer and the onsite walk around of the building. Based on the findings of the investigation, to prevent similar occurrences, employers should:
InvestigationThe building involved in the incident is of recent construction (~20-25 years old) and it is single story “tilt panel” construction. It is approximately 40 feet tall from ground to top edge of the building. The building has recently been used as a warehouse storage facility. The roof is flat construction with skylights added for additional lighting for the work areas below. The skylights were installed during construction. All the skylights are acrylic (plastic) domed, according to the roofing contractor. None have barricades or warning lines around them and the domes are not placarded with safety messaging relating to weight bearing and fall potential. Steel grills have not been installed beneath them. The building has a 5’ parapet wall surrounding the entire roof to prevent falls from working at or near the edge. The building’s owner contacted the roofing contractor to repair several small leaks that had recently developed. The job was estimated take about two days to complete. The roofing contractor was self-employed and was at times accompanied by his son who helped with roof repair work. The work to be done on the day of the incident was not in the immediate vicinity of any skylights. The roofing contractor noted that there were about a dozen skylights on the roof and reasoned that the risk of falling through a skylight was remote. In addition, his assessment included a concern for falls from the roof’s edge. Weather on the day of the incident was bright and sunny and the roof’s surface was dry and clear. Immediately preceding the incident the victim and his father had been talking, facing each other. The victim was backing up unrolling the torch’s hose, preparing to roll it up for storage and removal from the site. The father stated that he turned away from his son for “just a moment” to do something and heard a loud noise and immediately turned around in time to see, “the skylight exploding”. His son was not in sight. The father immediately went to the skylight opening and observed his son on the floor of the warehouse, below. A call was initiated for emergency services and the father went to be with his son. The victim’s father was not sure if his son stepped onto the skylight, tripped over something, or simply lost his balance and fell into it. Back to TopCause of DeathThe medical examiner’s determination at the scene was accidental death due to severe head trauma. Recommendations/DiscussionRecommendation #1: Employers should communicate known and potential safety hazards to all workers or visitors who access the work site.Discussion: Anyone entering the work site must be informed of potential safety hazards. Employers can emphasize their commitment to safety by enforcing a site specific safety plan, to identify and communicate potential safety hazards and methods to eliminate them. Employees have the right to question the safety of any task and they are responsible for following the practices outlined in their employer’s safety plan. It is not clear that through the completion of a pre-job site hazard assessment that any statement of concern for the risk of falls through the skylights was made to the worker. The skylights were “not in the immediate vicinity of the roofing work” and there was no reason to think that anyone would be entering the area of the roof where the skylights were installed, according to the employer. The victim fell through a skylight at the close of all work during clean up of the site and in preparation for leaving. He was walking backwards and rolling up a hose used for torch work. In doing this he left the “known” area where he had been working and entered a less familiar area where the skylights presented the fall hazard. There were no visual markers or barriers to identify the working area or the skylight area installed according to the roofing contractor.

In addition to grills, manufacturers of skylight products need to label them for risk of fall and any weight loading that they carry. Fire inspections, routine insurance inspections and regularly scheduled employer safety program inspections can provide an opportunity to evaluate the ongoing need to ensure maintenance of safety labeling and engineering controls for all installed skylights. Building and business owners can then prioritize risks and how they should be addressed.
Discussion: A site-specific safety plan (hazard analysis) serves to identify employer expectations, safe work practices, engineering safety devices or possible personal protective equipment required for a job. Job sites should be evaluated by an experienced worker to identify safety equipment and work practices that will be used to accomplish the work. Any safety issues or concerns should be identified before beginning work and become a part of the site’s work plan. As with any administrative change it’s not the implementation, but the integration of those expectations, into actions-taken, that will ultimately lead to a reduction in injuries. The owner/contractor acknowledged not having a written safety program or a formal training program. This employer reasoned that as a small operator (usually only himself) a formal safety/training program was not financially feasible and that it would make more sense for him to have a formal training program if he were a larger firm with more employees. Site-specific training is important and can be effective in preventing serious injuries or death.
The Center for Research on Occupational and Environmental Toxicology at Oregon Health & Science University performs Fatality Assessment and Control Evaluation (FACE) investigations through a cooperative agreement with the National Institute for Occupational Safety and Health (NIOSH), Division of Safety Research (DSR). The goal of these evaluations is to prevent fatal work injuries in the future by studying the working environment, the worker, the task the worker was performing, the tools the worker was using, the energy exchange resulting in fatal injury, and the role of management in controlling how these factors interact.
