Updated On: Jun 23, 2026
- Ethyl Alcohol
- Chlorhexidine
- Formaldehyde
- Sodium Hypochlorite
Show Solution
The Correct Option is D
Solution and Explanation
Infection Control -- Blood Spill Protocol:
Standard blood spill management steps:
1. Don gloves before approaching the spill
2. Absorb excess blood with disposable paper/cloth
3. Clean with water and detergent
4. Apply disinfectant: $\text{Sodium Hypochlorite}$ 0.5% (10,000 ppm available chlorine)
- Prepared as 1:10 dilution of 5.25% sodium hypochlorite bleach
- Must be freshly prepared daily
Why sodium hypochlorite?
- Broad-spectrum activity: bacteria, enveloped and non-enveloped viruses, fungi
- Inactivates HIV (requires 0.1% = 1000 ppm), HBV (requires 0.5% = 5000 ppm), HCV
- Cheap and readily available
- WHO and CDC recommended for blood/body fluid spills
Chlorhexidine = skin antiseptic. Alcohol = general surface disinfection. Formaldehyde = sterilant, not for spills.
\[\boxed{\text{Sodium Hypochlorite}}\]
