Weigh, measure, and record fuel used.

“Weigh, measure, and record fuel used.” is a core task performed by Stationary Engineers and Boiler Operators. Among the occupation's 25 rated tasks, workers place it 7th by importance (#19 most important). About 78% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

Work activities this task rolls up to

O*NET groups concrete tasks into broader work activities shared across many occupations.

• Measure physical characteristics of materials, products, or equipment. in Estimating the Quantifiable Characteristics of Products, Events, or Information
• Maintain operational records. in Documenting/Recording Information

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T3.
