Question

question 3 of 3 two employees were spreading concrete as it was being delivered by a concrete pumper truck boom. the truck was parked across the street from the worksite. overhead power lines ran perpendicular to the boom of the pumper truck. one employee was moving the hose (elephant trunk) to pour the concrete when the boom of the pumper truck came in contact with the overhead power line carrying 7,620 volts. the employee received a fatal electric shock and fell on the other employee who was assisting him. the second employee incurred serious electrical shock and burns. safety training requirement was not being carried out at the worksite. how could this tragic accident have been prevented? select all that apply image of workers with boom and power line having two employees operate the hose avoid operating equipment within ten feet of electrical distribution or transmission lines rated 59.9 kv or less erect insulation barriers a second pumper truck would have prevented this train employees to recognize and avoid unsafe conditions submit

Explanation:

• "Having two employees operate the hose" doesn't prevent electrical contact.
• "Avoid operating equipment within ten feet of electrical distribution or transmission lines rated 59.9 kV or less" is a safety measure to prevent contact with power lines.
• "Erect insulation barriers" can isolate equipment from power lines, reducing risk.
• "A second pumper truck" doesn't address the electrical hazard.
• "Train employees to recognize and avoid unsafe conditions" helps them identify risks like proximity to power lines.

Answer:

• Avoid operating equipment within ten feet of electrical distribution or transmission lines rated 59.9 kV or less
• Erect insulation barriers
• Train employees to recognize and avoid unsafe conditions
