Smelly Mel’s and Sewer Rat Plumbing swamped in fines – nearly $530,000 for serious accident-related violations
Foster City– The Division of Occupational Safety and Health, known as Cal/OSHA, has cited employers Smelly Mel’s Plumbing and Sewer Rat Plumbing a total of $529,640 in proposed penalties for violating safety regulations that resulted in serious injuries to a construction worker during a trench collapse in San Mateo on August 1, 2024.
Cal/OSHA, a division of the Department of Industrial Relations, found a total of 16 violations, evenly split between both businesses. Among these citations were two willful, serious accident-related violations–meaning the businesses were aware of the safety hazards, had prior warning, and still failed to take corrective action.
What Cal/OSHA Chief Debra Lee said: “Trench collapses remain one of the most serious hazards in construction, and employers must take all necessary steps to protect their employees. These citations serve as a reminder that businesses must prioritize worker safety, especially during high-risk operations to avoid tragic accidents.”
What happened: On August 1st, 2024, a crew was handling a sewer line project at a private residence in San Mateo. The job took a near-deadly turn when the walls of the trench collapsed, burying a worker under the debris and causing serious injuries that required hospitalization.
Key Violations and Safety Lapses: The citations issued include violations for improper protective systems, inadequate training, and failure to inspect the trench and surrounding conditions including:
- Inspection Failure: Employers did not ensure that a competent person conducted daily inspections of the trench, adjacent areas, and protective systems that could have detected hazardous conditions such as cave-ins.
- Lack of safe exit routes: Both employers failed to provide the construction workers a ladder or other safe means of exiting the trench that was approximately 9 feet and 3 inches in depth.
- No adequate protective systems in trench: Neither employer provided adequate protective systems, such as shoring, shielding, sloping, or benching to the trench to prevent its collapse.
- Failure to protect workers from falling debris: Neither employer protected their workers from excavated materials or equipment that could pose a hazard by falling or rolling into the trench.
- Foot Protection: The employer failed to ensure that their workers had proper foot protection, which exposed at least one worker to foot injuries when using a jackhammer.
- Insufficient emergency medical provisions: The employers did not have an appropriate number of trained persons to render first aid at the jobsite.
- Permit Requirements: The employers failed to notify the division prior to the start of the annual permit-required activity of constructing an excavation over 5-feet in depth.
- Injury and Illness Prevention Program: The employers failed to conduct a toolbox safety meeting at the jobsite with the crew for the duration of the project.
Employers have the right to appeal any Cal/OSHA citation and notification of penalty by filing an appeal with the Occupational Safety and Health Appeals Board within 15 working days from the receipt of notification.
