A plumbing contractor is operating a hydraulic excavator for trenching. To prevent serious injury in the event of a hydraulic line rupture or pinhole leak, what is the most important immediate action if hydraulic fluid contacts the skin?
- AApply a cold compress to the affected area.
- BImmediately seek medical attention, even if no pain is felt.
- CCover the area with a sterile bandage.
- DWash the affected area thoroughly with soap and water.
Show answer & explanationAnswer & explanation
Correct answer: B. Immediately seek medical attention, even if no pain is felt.
High-pressure hydraulic fluid injection injuries are extremely serious, even if initially painless. The fluid can cause severe tissue damage, necrosis, and systemic toxicity. Immediate medical attention is crucial for surgical removal and treatment to prevent permanent disability or amputation.
Why the other options are wrong
- A. A cold compress will not address the internal damage or chemical irritation caused by injected hydraulic fluid.
- C. Covering the wound without medical intervention delays critical treatment and can worsen the outcome of an injection injury.
- D. Washing with soap and water is insufficient for a high-pressure injection injury, as the fluid penetrates deep into tissues.
Hydraulic Fluid Injection Injury
A severe injury caused by high-pressure hydraulic fluid penetrating the skin, often appearing minor initially but causing extensive internal tissue damage.
- Initially painless, can be deceptive.
- Requires immediate surgical intervention.
- Can lead to tissue death, infection, amputation.
- Not treatable by simple washing.
Memory trick: Injection's a deception, seek medical reception.
