Engine smoke and emergency evacuation near a crowded bus stand
At 16:45 your 54-seat bus is 300 m from a busy bus stand when a passenger shouts that smoke is coming from the rear engine compartment. You see light grey smoke and smell burning rubber; there are no flames. The driver slows but keeps moving. There are 47 passengers, including a man on crutches, a woman with a six-month-old baby, and two elderly passengers. The bus is in the middle lane of a three-lane road. The fire extinguisher gauge shows green. The emergency door is on the right side, away from the traffic. A passenger has already opened the emergency door while the bus is still moving. The bus stand is crowded and the driver says he will stop there.
1. What should you do in the first 60 seconds, and what must the driver do?
Read the worked answer
The first 60 seconds are about stopping and preventing a panic-driven jump. Shout clearly: 'Stay seated, hold the rails, we are stopping.' Tell the driver to stop immediately in the nearside lane or at the bus stand, apply the parking brake, switch off the engine and turn on hazard lights. Do not wait for the stand if the engine is smoking.
As soon as the bus is stopped, secure the emergency door; it should not be open while moving. Check for heat and smoke at the rear, but do not open the engine cover fully - oxygen can feed a fire and steam can burn. If smoke increases or you see flame, evacuate immediately through the front and emergency doors, away from traffic, and assemble on the footpath. Assist the man on crutches, the mother and the elderly passengers, count passengers and keep the aisle clear.
2. When and how should the extinguisher be used, and what first aid may be needed?
Read the worked answer
Use the extinguisher only if the fire is small, you have a clear escape route and you have been trained. For an engine fire, discharge through the inspection gap or a partly opened cover, aiming at the base of the flame; do not stand directly over the engine. A green gauge means the extinguisher is pressurised, not that it is suitable for all fires; check that it is dry powder/ABC.
If smoke is heavy or flames are visible, evacuate and wait for the fire service. First aid: move anyone with smoke inhalation to fresh air, loosen clothing and do not let them walk if breathless. For burns, cool with clean running water for at least 20 minutes, cover loosely and do not apply oil or toothpaste. Keep the baby warm and monitor breathing; call emergency services.
3. What reporting and passenger-care steps follow after the incident?
Read the worked answer
Report immediately to control/depot and, if there was fire or injury, to police/fire service. Record the time, location, passenger count, smoke description, action taken, extinguisher use, injuries and evacuation. Preserve the extinguisher and do not reset it; note the gauge and service tag.
Get names and contacts of witnesses and injured passengers; offer assistance and arrange alternative transport. Do not resume service until a mechanic certifies the vehicle. Complete defect and incident reports and hand over copies with the trip sheet. Brief the next crew. Avoid posting on social media or speculating about the cause. If the emergency door was opened while moving, report it as a safety event and check the door mechanism.
