CAP question

Which of the following is true of operating instructions?

A. They require a set of books covering the total operation.
B. OSHA requires operating procedures for all installations.
C. They may be included in a functional specification or operating description.
D. ISA standards guide in the development of operating instructions.

CAP Answer

The correct answer is C, “They may be included in a functional specification or operating description.” Operating instructions may be included in a functional specification or operating description and may range from a few pages describing how to operate one part of a plant to a complete set of directions covering all parts of a facility.

Answers B and D are not correct. There are no ISA standards available to aid in developing operating instructions. OSHA requires operating procedures for all installations handling hazardous chemicals, but not for those that do not.

Answer A is not correct. Operating instructions can be printed (e.g., books or manuals) or electronic (e.g., PDF) and can cover from one step of the process to an entire operation. For each use, operating procedures are usually limited to a single operation or set of operations.
