Smoke in the Rear Lavatory at 23:40
23:40 on a divided four-lane highway. You are driving a 56-passenger motorcoach with 44 passengers aboard, already 40 minutes behind schedule. You smell burning insulation, then see smoke curling out of the rear lavatory area. You pull onto the right shoulder and stop. The smoke is thickening, the rear door sits about 6 feet from the lavatory, and the front door opens onto the shoulder. The right-hand windows are push-out emergency exits; the left side faces traffic passing at 70 mph roughly 12 feet away. It is 30°F and windy, with a guardrail on the shoulder side and a shallow ditch beyond it. Two passengers use wheelchairs and one cannot transfer without help. A passenger in row 3 is filming, and another is shouting that the bus will explode. You have a current passenger manifest in the driver's area.
1. Which exits do you use, in what order, and how do you move 44 people away from the vehicle?

Sequence matters: stop feeding the hazard, get them out, then get them away.
- Front door first. The smoke is at the rear and the front door opens onto the shoulder, away from the 70 mph lane. Announce it clearly: "Everyone off by the front door - leave your bags." Bags cost lives in an evacuation.
- Keep the rear door as a last resort. Opening it next to the lavatory feeds the fire air and pushes people into smoke.
- Windows if the front door becomes unusable. The right-side push-out windows open toward the shoulder and guardrail - the safer side. Assign two able passengers to operate windows and hand people down over the guardrail. Never route people out the left side into live traffic.
- Direct the flow away, not just out. Get them at least 100 feet upwind, behind the guardrail, not clustered at the bumper. The bus is not shelter once it is burning.
- Calm the shouters by giving them a job. "You - take this group to the guardrail and keep them there" converts panic into a task. The filming passenger is harmless; ignore the camera.
Smoke, not flame, is what kills in a bus fire, and burning wire insulation produces dense toxic smoke. The decision to evacuate should be made early, on the first smell, not after a second look.
2. How do you account for everyone, and what is your plan for the two wheelchair users, one of whom cannot transfer?

Accountability starts before the emergency. The manifest is only useful if it is current - seat count, names, and who occupies the two securement stations.
- Count heads at the assembly point and compare to the manifest. 44 aboard means 44 away from the bus. If the count is short, tell the first responders immediately, with a description and where in the coach that person was last seen. Do not send untrained passengers back inside.
- The chair is equipment; the person is the priority. In a smoke evacuation there is no time to deploy a lift. Use a two- or four-person carry, or an aisle chair if one is aboard, and pre-assign helpers - ideally the travel companions - at boarding time, not at the fire.
- Do not leave the non-ambulatory passenger for last and do not assume a stranger will step in. Name the helpers out loud: "You and you, take her arms; you take her legs."
- Once out, keep them off the traffic side. A person in a wheelchair on the traffic side of a 70 mph highway is a second emergency. Move them behind the guardrail with the rest of the group.
If one passenger is unaccounted for, that is the single most important fact you will give the fire department, so make sure your count is by name or by face, not a rough number.
3. What notifications do you make, in what order, and what do you record afterward?
Read the worked answer
911 and dispatch need different things, so give each its own short, complete call.
- 911 first: divided four-lane highway, direction of travel, mile marker or last exit, 44 passengers, smoke from the rear of a motorcoach, no confirmed injuries yet, patients assembling behind the guardrail on the right shoulder. Say "motorcoach" so enough units are dispatched.
- Warning devices only if it costs no evacuation time: triangles or reflectors behind the bus, but never by walking into a live lane at night.
- Dispatch second: coach number, location, passenger count, whether a replacement coach is needed, and that the manifest is in your hand.
- Record afterward: times, what you saw and smelled, what you did, who you spoke to, and any injuries reported later that day. Incident reporting gets written the same night while it is accurate, not reconstructed next week from memory.
Do not move the coach unless it is on fire or blocking a live lane. The vehicle is evidence, and an electrical smoke source can re-ignite once it has air.
