Laceration in Sewage-Contaminated Basement Water
At a sewage-contaminated basement cleanup, a worker wearing cotton gloves and rubber boots cuts his right palm on a submerged metal shelf edge. The cut bleeds moderately. He rinses it in the standing water and continues working for 20 minutes. The basement water contains raw sewage; the crew has no first aid kit on site. A second worker has a minor scrape on her forearm from the same shelf. The crew's only hand sanitizer is empty. They are 25 minutes from the nearest urgent care. The worker's tetanus vaccination status is unknown; he says he had a shot about 10 years ago. The crew leader must decide about wound care, decontamination, and reporting.
1. What immediate first aid and decontamination steps should be taken for the injured worker?
Read the worked answer
The worker should stop work and leave the contaminated area. He should remove the cotton gloves without touching the wound, then wash the cut thoroughly with clean running water and soap for at least 15 minutes. Rinsing in standing sewage water was inappropriate because it adds pathogens. The wound should be covered with a clean, dry dressing after washing. Because the cut is moderate and contaminated with sewage, he should be taken to urgent care or an emergency department for evaluation, possible tetanus prophylaxis, and consideration of antibiotics. The leader should arrange transportation and not let him drive if he is faint or in pain. The second worker's scrape should also be washed with clean water and soap and covered. The leader should document the time of injury, exposure, and first aid given.
2. What decontamination and bloodborne-pathogen considerations apply to the crew and equipment?
Read the worked answer
Sewage contains bacteria, viruses, and parasites, so the exposure is a pathogen exposure even if no human blood is visible. The worker's bleeding makes bloodborne-pathogen precautions relevant for anyone providing first aid; use gloves and avoid contact with blood. Contaminated gloves, dressings, and clothing should be bagged and not worn into vehicles or clean areas. Boots and tools should be washed with detergent and water and disinfected as appropriate. The crew should wash hands with soap and water; empty hand sanitizer is not a substitute for handwashing after visible contamination. The leader should report the exposure to the site safety officer and follow the site's exposure-control plan, including medical follow-up and documentation. Other workers should be checked for cuts before continuing.
3. What prevention and reporting actions should the leader take after the incident?
Read the worked answer
The leader should restock a first aid kit, provide waterproof gloves and cut-resistant gloves for debris removal, and ensure clean water and soap are available for handwashing. Workers should be trained not to rinse wounds in standing water and to report injuries immediately. The leader should check tetanus vaccination status and encourage workers to stay current. An incident report should describe the task, the shelf edge, the PPE used, the first aid given, and the medical referral. The leader should also inspect the basement for other submerged sharp edges and remove or mark them before work resumes. Finally, the leader should verify that the site's exposure-control and medical-response procedures were followed and share lessons learned with the crew.
