A Leaking Can in Row Nine

At 8:20 p.m. you drive an intercity bus with 30 passengers, 20 minutes from the next scheduled stop. A passenger in row 9 sets a plastic gasoline can on the floor; the cap is loose, the can is leaking, and the cabin smells strongly of fuel. Another passenger is smoking in the restroom, and smoke is visible near the ceiling. Your personal phone rings; the screen shows your child's school. A man you do not recognize asks whether he can 'just ride to the next exit' without a ticket; he is carrying a large duffel bag. The bus is on a four-lane highway with no shoulder for the next half mile. The fire extinguisher is mounted behind your seat, and the emergency exits are marked.

1. What are your immediate safety priorities with the leaking gasoline can and the smoking passenger?

Read the worked answer
  • The gasoline can is the top priority. Gasoline is a flammable hazardous material and is not allowed in the passenger cabin. A leaking can creates vapor that can ignite from a cigarette, engine, or electrical source.
  • Get to the first safe stopping place. Because there is no shoulder for half a mile, slow down, use hazard lights, and avoid sudden moves. Do not wait 20 minutes to the scheduled stop.
  • Stop, keep passengers calm, and evacuate them away from the bus and upwind. Do not handle or move the leaking can yourself.
  • Call 911 and dispatch; report a fuel leak and possible fire hazard.
  • Smoking: Tell the passenger to extinguish the cigarette immediately. Smoking is prohibited on the bus and is especially dangerous near fuel vapor. If the passenger refuses, treat it as an emergency and evacuate.
  • Do not resume the trip until fire or emergency personnel clear the bus.

2. How do you handle your ringing phone and the unauthorized rider with the duffel bag?

Read the worked answer
  • Phone: Do not answer a handheld phone while driving. Even a call from your child's school does not justify handheld use. Stop in a safe place first; after the bus is secure, use the phone or radio. During the fuel leak, emergency communication should go through dispatch or 911 and should not delay evacuation.
  • Unauthorized rider: He has no ticket and cannot ride. Ask him to wait for the next stop; do not physically confront him or block him if he becomes aggressive.
  • Duffel bag and security awareness: You do not have authority to search the bag. Observe and report: size, description, behavior, and destination. If he refuses to leave or acts threateningly, keep distance, stop the bus in a safe place, and call dispatch, security, or 911.
  • Do not let an unticketed rider board just to avoid conflict; that is both a policy violation and a security risk.

3. After the incident is controlled, what reporting and post-trip steps are required?

Read the worked answer
  • Provide a written incident report: date and time, location, passenger count, what the gasoline can looked like, who owned it, the smoking passenger, the unauthorized man's description, and what you said and did. Include witness names if passengers will provide them.
  • Notify dispatch and company security immediately; preserve any video or radio recordings.
  • The bus must be inspected for fuel contamination and damage before it returns to service. Check the extinguisher, emergency exits, and interior. If the extinguisher was used, replace or recharge it.
  • Tag the bus out of service if there is any fuel smell, damage, or unsafe condition; a qualified person must clear it.
  • Complete the post-trip vehicle defect report and, if required, a hazardous-materials release report. Do not clean up fuel yourself unless trained and authorized.
