Ensuring CNG Safety in School Bus Fleets: Best Practices for Fleet Managers

The Importance of CNG Safety in School Bus Fleets

As more school districts transition to buses powered by compressed natural gas (CNG), fleet managers must prioritize their safety. Implementing industry best practices will minimize risks for maintenance technicians, drivers, and students, as well as enhance fleet efficiency, reduce maintenance and repair costs, and meet relevant regulations. Let’s explore how to promote CNG safety in school bus fleets in greater detail.

1. Comprehensive Technician Training

A well-trained maintenance team is critical to the safe operation of CNG buses. Fleet managers should:

• Invest in comprehensive CNG training programs that teach technicians about fuel system inspections, fuel handling, and safety protocols.
• Provide training that includes real-world scenarios.

2. Industry Standards

Fleet managers must stay informed about federal, state, and local regulations governing CNG vehicle safety, to include:

• ANSI NGV 6.1, the required installation standard for natural gas fuel storage and delivery.
• NFPA 52 to mitigate fire and explosive hazards.
• DOT regulations for alternative fuel vehicles.

3. Preventative Maintenance and Inspections

Routine CNG fuel system inspections can identify potential issues before they become major safety hazards. Best practices include:

• Conducting pre- and post-trip inspections to assure components, cylinders, fuel system are all in good repair. 
• Scheduling periodic inspections and maintenance for fuel cylinders, valves, and pressure regulators.
• Using diagnostic tools to monitor fuel system integrity.

4. Safe Fueling and Storage Practices

Proper fueling procedures are key to accident prevention. Guidelines include:

• Training drivers and technicians on the correct fueling process.
• Knowing what to monitor during the fueling process. 
• Being aware of emergency protocols at a CNG station.

5. Addressing Technician Concerns

Because they’re working with high-pressure fuel, technicians may have concerns about working on these types of fuel systems. Fleet managers can alleviate those concerns by:

• Providing clear safety protocols and emergency response procedures.
• Equipping maintenance facilities with proper ventilation and gas detection systems.
• Encouraging open communication to address safety-related questions.

6. Balancing Training With Fleet Efficiency

One common challenge for fleet managers is minimizing downtime while technicians undergo training. Strategies to mitigate this include:

• Implementing staggered training schedules to ensure continuous fleet operations.
• Partnering with AFVi for flexible CNG training.
• Leveraging online modules when available and appropriate.

7. Enhancing Fleet Reliability and Cost Savings

By prioritizing safety and training, fleet managers can:

• Reduce unexpected breakdowns and repair costs.
• Extend the lifespan of CNG buses.
• Improve fuel efficiency and overall fleet performance.
