Question: A plumber is preparing to install new drainage piping in a residential basement. During the initial inspection, they notice several large, brittle-looking pipes wrapped in white, fibrous material in the area where they need to work. What is the immediate safety action they should take?

Answer options: ✅ Stop work, secure the area, and contact a qualified asbestos abatement professional.

• Proceed carefully, ensuring not to disturb the material, and wear an N95 respirator.
• Mist the material with water to prevent fibre release and then begin work while wearing a dust mask.
• Assume it is harmless insulation and continue with the work, as it's a common older material.

Correct answer: Stop work, secure the area, and contact a qualified asbestos abatement professional.

Explanation: If a plumber encounters material suspected to be asbestos, the immediate and correct action is to stop work, secure the area, and contact a qualified asbestos abatement professional. Disturbing asbestos-containing materials can release harmful fibres into the air, posing a significant health risk. Assuming it is harmless or only wearing inadequate PPE is dangerous.
