What is the correct sequence of steps if a fill hose ruptures during the transfer of a liquid pesticide?

The identified sequence of shutting off the mixing tank pump, containing the spill, and cordoning off the area is critical for ensuring safety and environmental protection. When a fill hose ruptures, the first priority is to minimize the risk posed by the spilled pesticide.

Shutting off the mixing tank pump prevents further product from escaping, reducing the potential severity of the spill. This action addresses the immediate hazard by stopping additional leakage. Next, containing the spill helps prevent the pesticide from spreading, which could lead to environmental contamination or pose risks to people and wildlife nearby. Finally, cordoning off the area ensures that no one enters the hazardous zone, protecting personnel from exposure and accidents.

This methodical approach not only prioritizes safety but also lays the groundwork for proper clean-up procedures that comply with regulations regarding pesticide spills. It highlights the importance of quick and effective response actions in the event of equipment failure to safeguard both human health and the environment.
