In late June, trained professional inspectors in Canada and the U.S. inspected 7,572 commercial motor vehicles transporting hazardous materials/dangerous goods (HM/DG) during the Commercial Vehicle Safety Alliance’s (CVSA) annual five-day unannounced HM/DG inspection and enforcement initiative.
Thirty-seven jurisdictions participated in this year’s HM/DG Road Blitz, which was June 12-16. A total of 8,395 packages were inspected, and inspectors discovered 2,578 HM/DG violations, of which 701 were HM/DG out-of-service (OOS) violations.
Vehicles that had out-of-service HM/DG violations were removed from roadways until those violations could be corrected. Vehicles that passed a North American Standard Level I Inspection without any critical inspection violations or specification cargo tank vehicle violations were eligible to receive a CVSA decal and permitted to continue to their destination.
The transportation of HM/DG demands rigorous training and heightened compliance requirements. For motor carriers and drivers, safely transporting HM/DG is imperative to the safety of the driver, the public and the environment. For inspectors, inspecting vehicles transporting HM/DG is a complex and detailed process that involves safely looking for any leaking materials or unsecured HM/DG cargo, and checking shipping papers, placarding, marking, labeling, packaging and loading compliance.
The annual unannounced HM/DG Road Blitz aims to:
- Spotlight the importance of the programs, processes and regulations associated with the safe transportation of HM/DG.
- Recognize safety-compliant HM/DG drivers, motor carriers, manufacturers, shippers, etc.
- Highlight the specially trained inspectors who prioritize transportation safety by inspecting vehicles transporting HM/DG and enforcing strict compliance regulations.
- Identify all shipping paper, placarding, marking, labeling, packaging and loading compliance violations.
- Remove vehicles with HM/DG out-of-service violations from roadways.
There are nine recognized classes of HM/DG. These classes designate HM/DG into categories, based on the materials’ specific chemical and physical properties, and describe the different types of risks associated with those materials.
|Number of HM/DG Classes Inspected|
|Class 1||Explosives, such as ammunition, fireworks, flares, etc.||40||137||177|
|Class 2||Gases, Flammable, non-flammable oxygen and inhalation hazards||348||1,392||1,740|
|Class 3||Flammable and combustible liquids, such as fuel oil, acetone, adhesives, paints, gasoline, ethanol, methanol, some pesticides, etc.||628||3,326||3,954|
|Class 4||Flammable solids, substances liable to spontaneously combust and substances that, on contact with water, emit flammable gases, such as white phosphorus and sodium.||48||155||203|
|Class 5||Oxidizing agents and organic peroxides, such as hydrogen peroxide, potassium permanganate, sodium nitrite, ammonium nitrate fertilizers and oxygen generators.||58||173||231|
|Class 6||Toxic and infectious substances; any material, other than a gas, that is so toxic to humans that it presents a health hazard during transportation, such as cyanide, biological samples, clinical wastes and some pesticides.||40||121||161|
|Class 7||Radioactive materials, such as cobalt-60 and cesium-137.||5||41||46|
|Class 8||Liquid or solid corrosive substances, such as sulfuric acid and sodium hydroxide, that cause full thickness destruction of human skin at the site of contact within a specified time.||266||989||1,255|
|Class 9||Miscellaneous HM/DG, such as acetaldehyde ammonia, asbestos, elevated temperature materials and benzaldehyde.||98||468||566|
