Where must a fumigation accident response plan be located?

The correct answer is that the fumigation accident response plan must be located at each work site. This is critical because having the plan readily accessible at the location where fumigation is taking place ensures that all employees can quickly reference it in case of an emergency. The response plan typically contains crucial information such as emergency contacts, procedures for handling accidents, and safety measures specific to that site.

By placing the plan at each work site, it allows for immediate accessibility during a situation that demands swift action. This reduces the time it takes for employees to find the necessary information, thereby improving response times and safety outcomes. Other locations, such as the employer's files or an employee's vehicle, do not guarantee immediate access in an emergency at the work site, while placing it on the employee bulletin board may not ensure that it is easily seen or reviewed before an incident occurs.
