Study Notes
General HazMat Regulations
- Three primary lists exist to classify hazardous materials: DOT Hazardous Materials Table, EPA list, and IATA Dangerous Goods list.
- Drivers of placarded vehicles must stop 15 to 20 feet from railroad tracks when transporting hazardous materials.
- Vehicles must display four identical placards: front, back, and both sides.
Placards and Signage
- DOT specifications have 31 different types of placards.
- Placards must be 10 3/4 inches square or in a diamond shape.
- For inhalation hazards, the "poison" placard must be used.
- Combine explosive classes (like 1.1 and 1.3) require specific placarding based on the materials being transported.
Safety Equipment and Operations
- Approved gas masks are required for any vehicle carrying chlorine.
- A U.L. rating of 10 B/C or above fire extinguisher is mandatory in the power unit of a placarded vehicle.
- When fueling a placarded vehicle, one person must be at the nozzle to control the fuel flow.
Emergency Protocols
- In the event of an accident involving hazardous materials, evacuation and keeping people far away and upwind is essential.
- Reflective triangles are appropriate signals for warning of a stopped vehicle with explosives.
- If there is a spill of an "RQ" substance, it must be reported within 15 days.
Shipping Papers and Documentation
- Shipping papers must list: identification number, proper shipping name, hazard class, and packing group in that order.
- The proper shipping name must appear first on shipping papers for hazardous materials.
- A dated certificate from the employer must be carried by the driver and updated every two years.
- Hazardous waste manifests need to be tabbed differently and kept on top of the paperwork.
Packaging and Loading Guidelines
- Cylinders containing compressed gases require specific loading conditions to prevent turning over.
- Explosives should not share trailers with heaters or air conditioning units due to safety hazards.
- If a package is leaking, a driver must refuse the shipment even if it has a signed certificate.
Hazard Classifications
- There are nine hazard classes, including explosives, flammable liquids, gases, oxidizers, toxic substances, radioactive materials, corrosives, and miscellaneous hazardous materials.
- Class 1 refers to explosives, while Class 2 is for gases, including flammable gases.
- Class 3 is designated for flammable and combustible liquids, while Class 4 encompasses flammable solids.
Driver Responsibilities
- Drivers must undergo training every two years to remain compliant with hazardous materials regulations.
- The driver is responsible for the safe transport of materials, checking that shippers have correctly labeled hazardous material shipments.
- Smoking regulations prohibit smoking near transporting hazardous materials; specific distances vary by class.
Special Considerations
- No vehicle transporting hazardous materials can stop within 300 feet of an open fire.
- Class A and B explosives cannot be transported in combination vehicles with placarded cargo tanks.
- A vehicle with placarded materials must be grounded when filling or unloading flammable liquids.
Transportation Permits and Routes
- The driver is responsible for understanding and acquiring necessary permits for transporting hazardous materials along specified routes.
- Unsafe conditions, such as overheated tires, must be addressed immediately, including the safe removal of the tire from the vicinity of the vehicle.
Packaging and Labeling
- Proper packaging and labeling of hazardous materials are crucial; shippers must ensure compliance, with exceptions only when shipping their products.
Miscellaneous Guidelines
- A vehicle carrying explosives must not be moved more than necessary if there is a spill.
- Two or more hazardous materials with conflicting requirements cannot be transported together.
- Drivers must keep shipping papers accessible while driving, especially when wearing a seatbelt.
