Hazmat Today takes a close look at compliance reviews, the in-depth investigations which determine valid ratings for designated businesses, as mandated by the federal government. Studies of the work being done by safety investigators have revealed some concerns about the data being captured during compliance reviews. Information vital for the carrier’s rating is sometimes being overlooked and not included in the report. For example, companies transporting hazardous materials are sometimes not being identified as hazardous materials carriers. Occasionally, investigators do not probe enough for information about the carrier’s business activities and consequently are not uncovering information that may be important to the rating process. Hazmat Today can help investigators to establish the role of hazardous materials in any operation and help them develop techniques to probe beyond routine questions during a compliance review.
