Where must a copy of the current SOP for a particular activity be kept?

• A. In a location easily accessible by each coal mine worker
• B. In the mine's central control room
• C. With the activity supervisor only
• D. In the safety office's filing cabinet

Answer: (A)

SOPs for any activity must be readily accessible to every worker performing that activity, so they can review the documented procedure at the point of work. Keeping a copy in a location easily accessible by all coal mine workers ensures everyone can refer to it before and during the task, supporting safe, compliant operation. Placing it only in the central control room, with the supervisor only, or in the safety office cabinet would limit access and hinder workers from consulting the current procedures when they need them.
