How should you respond to weather changes affecting operations?

Answer: C — Reassess hazards, adjust procedures, communicate changes, and wear appropriate PPE.

Weather changes introduce new hazards that can affect braking distances, traction, visibility, and worker safety. The best approach is to reassess the hazards in the current conditions, adjust procedures to address those hazards, communicate the changes to everyone involved, and wear PPE appropriate to the conditions. This means reviewing the weather and track or equipment conditions, slowing down or altering operating rules as needed, updating routines for switching, signaling, and train handling, and making sure the crew is aware of the updated plan. PPE should match the conditions—high-visibility gear in low visibility, rain gear, gloves, eye protection, and any other protections required for the situation. Ignoring weather, stopping operations entirely without a plan, or relying on PPE alone doesn’t reduce the underlying risks.
