Question

a worker with 8 years experience on the job was removing metal fish tape from a ... box in a ... area. it was raining during the course of the work. the fish tape became ... , increasing risk. what could have been done to prevent this problem? select all that apply image of a worker with a tool four options: 1) ensure all circuits are de - energized before beginning work, 2) this type of work shouldnt have been conducted in the rain, 3) (blurry text about measurements during work), 4) (blurry text about worker training to recognize and react to issues related to work)

Explanation:

To solve this problem, we analyze each option based on workplace safety and electrostatic discharge (ESD) principles:

Option 1: "Personnel should be grounded before beginning work"

Grounding personnel (e.g., using anti - static wrist straps) prevents static buildup, which could ignite flammable metal dust. This is a valid prevention method.

Option 2: "This type of work shouldn’t have been conducted in the rain"

Rain increases moisture, which can cause electrical hazards (e.g., short - circuits, equipment damage) and make metal dust more conductive, increasing fire/explosion risks. Conducting this work in the rain is unsafe, so avoiding rain - time work is valid.

Option 3: "Measurements during the course of work (is supposed to be) connected to grounded equipment or (at) log intervals"

This option is unclear and grammatically flawed. Proper measurement practices for static or dust levels should involve grounded equipment, but the wording is confusing. However, the core idea of using grounded equipment for measurements to monitor hazards is reasonable in context.

Option 4: "Personnel should have been trained to recognize and avoid unsafe conditions associated with his work"

Training workers to identify hazards (e.g., static buildup, wet conditions, dust ignition risks) is a fundamental safety practice. This would help the worker prevent the problem.

Answer:

1. Personnel should be grounded before beginning work
2. This type of work shouldn’t have been conducted in the rain
3. Measurements during the course of work (is supposed to be) connected to grounded equipment or (at) log intervals (note: wording issues but conceptually relevant)
4. Personnel should have been trained to recognize and avoid unsafe conditions associated with his work

(All options, except for potential wording issues in option 3, relate to preventing the problem of metal dust ignition due to static/unsafe conditions.)
