Discuss HRPA CHRP-KE Exam Topic 2 Question 12

Considering risk control measures that can be used to minimize hazard exposure, which of the following is an example of controlling the hazard's path?

AMopping the floor following a chemical spill.

BReplacing malfunctioning equipment.

CProviding hearing protection to a worker.

DOpening a window to provide ventilation.

Suggested Answer: D

HRPA's health and safety competencies require applying the hierarchy of controls and understanding control strategies at the source, along the path, and at the worker. Controlling the path refers to interrupting or redirecting the transmission of a hazard between source and worker (e.g., ventilation, isolation, or barriers). Opening a window to provide ventilation reduces airborne contaminant concentration along its path, fitting this category.

Mopping a spill (A) is housekeeping/source removal after release; replacing equipment (B) is a source/engineering control; hearing protection (C) is PPE at the worker.

Relevant HRPA references: Professional Competency Framework --- Health, Wellness & Safe Workplace (apply the hierarchy of controls; distinguish source, path, and worker controls); Study Guide content on ventilation as a path control.

C is good for protection, but it doesn't control the hazard's path.

I feel like B is crucial too. Replacing equipment stops hazards.

True, but A is more about cleanup, not controlling the path.

Devorah 23 days ago

But A is also important. Mopping prevents further exposure.

I agree, Alex. It controls the hazard's path effectively.

I think D is the best choice. Ventilation is key.

Mona 1 month ago

I feel like C is protective, but not about the hazard's path.

Tomas 1 month ago

D directly affects the air quality, so it makes sense.

B is crucial too, but it doesn’t control the hazard's path.

Lou 2 months ago

A is also important, but it’s more about cleaning up.

Tamie 2 months ago

I agree, opening a window helps clear out fumes.

Shawna 2 months ago

I think D is the best choice. Ventilation is key.

Kristel 2 months ago

I’m not sure about D, seems too simple for a real hazard.

Adolph 2 months ago

Wait, opening a window? Is that really effective?

Barrie 3 months ago

Totally agree with D! Fresh air helps a lot.

Keneth 3 months ago

I think A is more about cleaning up, not controlling the path.

Sage 3 months ago

D is definitely controlling the hazard's path.

Geoffrey 3 months ago

Not sure if D is the best answer, seems too simple.

Rodolfo 3 months ago

Wait, can opening a window really help that much?

Adria 4 months ago

Totally agree with D! Fresh air makes a big difference.

Elvera 5 months ago

I think A is more about cleaning up, not controlling the path.

Rosio 5 months ago

D is definitely controlling the hazard's path.

Leota 6 months ago

I agree with the idea of ventilation being a control measure. It seems like opening a window would help redirect the hazard away from workers.

Rosann 6 months ago

I'm not entirely sure, but I feel like providing hearing protection is more about personal safety than controlling the hazard's path.

Jess 6 months ago

I remember a practice question about hazard control, and I think mopping the floor is more about cleaning up rather than controlling the path.

Naomi 6 months ago

I think controlling the hazard's path might relate to how we manage the environment around the hazard. So, maybe opening a window for ventilation could be it?
