Example:

These safety precautions are the minimum necessary for work in a fuel tank. But the local regulations can make other safety precautions necessary.

Section 5 - Procedures

Summary of the Rules

RULE: 5.1 Keep procedural sentences as short as possible (20 words maximum).

RULE: 5.2 Write only one instruction per sentence.

RULE: 5.3 Write more than one instruction per sentence only when more than one action is done at the same time.

RULE: 5.4 In an instruction, write the verb in the imperative ("commanding") form.

RULE: 5.5 If you start an instruction with a descriptive statement (dependent clause), you must separate that statement from the rest of the instruction with a comma.

Refer also to these rules, which are closely related:

Word Counts: Rules 8.2, 8.4 thru 8.9

Active Voice of Verbs: Rule 3.6

Tabular Layout: Rules 4.3, 8.1

Sentence Length

RULE: 5.1 Keep procedural sentences as short as possible (20 words maximum).

The maximum length of a procedural sentence is 20 words. (Refer to Section 8 for the rules about word count.)

Example:

WRITE: (1) Remove the electrical power from the system. (Seven words)
(2) Make sure the refueling panel switches go back to their correct position (Twelve words)
NOT: After you have removed the electrical power from the system, make sure that the refueling panel switches go back to their normal position. (Twenty-three words)

RULE: 5. 2 Write only one instruction per sentence.

If you put all your instructions into one or two sentences, you will overwhelm your readers. Therefore, you must present your instructions one at a time. This will let your readers complete one item before they start another.

Example:

WRITE: (1) Set the TEST switch to the middle position.
(2) Release the SHORT-CIRCUIT TEST switch.
NOT: Set the TEST switch to the middle position and then release the SHORT-CIRCUIT TEST switch.

RULE: 5.3 Write more than one instruction per sentence only when more than one action is done at the same time.

Some instructions or actions need to be done either simultaneously or almost at the same time (for instance, in one motion). It is permitted in these cases to have more than one instruction in a sentence.

Examples:

 Hold the switch to the TEST position and make sure the light comes on.
