In case of a fuel leak, what is the first step that tank setters should take?

In the event of a fuel leak, the first step that tank setters should take is to notify the appropriate environmental authorities. This step is crucial for several reasons. First, fuel leaks can pose serious environmental and health risks, including soil and groundwater contamination. By notifying the authorities, tank setters ensure that trained professionals can respond to the situation effectively and mitigate potential hazards.

Taking immediate action by contacting the proper agencies helps in assessing the extent of the leak and implementing containment measures, which are vital in preventing further environmental damage. Moreover, legal regulations often require professionals in the field to report such incidents promptly to maintain compliance and public safety.

Taking matters into their own hands, as suggested in one of the other options, could lead to improper cleanup methods that might exacerbate the issue or fail to address it adequately. Ignoring the situation or waiting for customer complaints would not only be irresponsible but could also have legal repercussions. Thus, prioritizing proper notification aligns with best practices for safety and environmental protection.
