In any suspected occupational exposure, the first step is a detailed occupational history to assess the nature, intensity, and duration of the exposure. This determines whether surveillance or further testing is appropriate.

Toronto Notes 2023 – Respiratory Medicine, “Occupational Lung Diseases” Section:

“When a patient presents with concerns about exposure to occupational hazards such as asbestos, detailed history is essential. Ask about job tasks, duration of exposure, use of personal protective equipment, and prior workplace assessments.”

MCCQE1 Objectives (Population Health > 97-2: Environmental and Occupational Health):

“Candidates must be able to obtain a detailed environmental and occupational history and determine the risk of exposure before ordering investigations.”

Ordering a chest radiograph (B) or PFTs (E) without confirming meaningful exposure is premature. Referral to a specialist (D) and reassurance (A) come only after the exposure risk is assessed.
