  1. The Commercial Vehicle Safety Alliance's (CVSA) International Roadcheck will take place June 4-6. Over that 72-hour period, commercial motor vehicle inspectors in jurisdictions throughout North America will conduct inspections on commercial motor vehicles and drivers. This year's focus is steering and suspension systems. While checking vehicle compliance is always part of the North American Standard Inspection Program, CVSA is highlighting steering components and suspension systems this year as a reminder of their importance to highway safety.

About Us


Our team

Although Railsback HazMat Safety Professionals (HMSP) is a company of me, myself and I, making Professionals plural is stressing that everyone involved in the transportation of hazardous materials is needed to ensure safety and compliance. Railsback HazMat Safety Professionals is owned and operated by Rex Railsback.  Rex has over 21 years of experience within the Hazardous Materials and Transportation community, dealing with compliance and training, as part of a 28 ½ year career as a Kansas State Trooper.  This experience is not limited to the State of Kansas, but throughout the United States training enforcement, regulatory and industry personnel. 


Our history

Rex Railsback has over 21 years of experience within the Hazardous Materials and Transportation community, dealing with compliance and training, as part of a 28 ½ year career as a Kansas State Trooper.  During this career, Rex was a Master Instructor for the Federal Motor Carrier Safety Administration, National Training Center (NTC) in General Hazardous Materials, Cargo Tank Inspection, Other Bulk Package and North American Standard Inspection Part A and Part B.  Rex was also recognized as a subject matter expert for the courses.  Rex has delivered countless hours of instruction to enforcement and industry members over his career.  His ability to understand, interpret and train others on the convoluted federal regulations is second to none.  The knowledge and experience held by Railsback HazMat Safety Professionals could only have been obtained through decades of hands-on, real world application of hazardous materials enforcement. Rex conducted compliance reviews of motor carriers, hazardous materials shippers and cargo tank facilities to ensure compliance with federal regulations.  Rex is a past International Chair of the Cooperative Hazardous Materials Enforcement Development Program (COHMED) of the Commercial Vehicle Safety Alliance (CVSA).  Rex was a voting member on the CVSA hazardous materials, training and vehicle committees at annual conferences for several years. Upon retirement in December of 2017, Rex held the rank of lieutenant within the Motor Carrier Safety Assistant Program, Commercial Vehicle Enforcement with the Kansas Highway Patrol and was the State Hazardous Materials Specialist for Transportation.
