Question 43

Pour bleach on the spill and let it soak for 60 seconds.

Pouring bleach on the spill and allowing it to soak for 60 seconds is the appropriate action to disinfect the area, as bleach is effective in killing pathogens present in blood.

A) Cover the spill until maintenance arrives

While covering the spill may prevent further contamination or exposure, it does not address the need for disinfection. This action could delay the necessary cleaning and sanitization of the area, which is critical in a laboratory setting involving biological hazards.

B) Pour bleach on the spill and let it soak for 60 seconds

This is the correct action as bleach is a strong disinfectant effective against bloodborne pathogens. By allowing it to soak for the recommended time, it ensures that the bleach can effectively kill any infectious agents present in the blood.

C) Evacuate the laboratory

Evacuating the laboratory may be a precautionary measure in extreme cases, but it does not resolve the immediate need to clean and disinfect the spill. It may also unnecessarily disrupt laboratory operations if the spill can be managed safely with the right cleaning protocol.

D) Apply a liquid thickening agent on top of the spill

While applying a thickening agent may help contain the spill, it does not effectively disinfect the area. The primary concern with a blood spill is to ensure that the pathogens are neutralized, which a thickening agent alone does not achieve.

Conclusion

Pouring bleach on the spill is the most effective method for disinfection, addressing both safety and hygiene concerns in the laboratory. Other options either fail to adequately disinfect the area or do not provide a comprehensive solution to managing the biohazard effectively. Thus, option B is definitively the correct choice.
