In what category are most laboratory specimens classified?

Most laboratory specimens are classified as Category B materials. This classification is specifically designated for infectious substances that are capable of causing disease in humans or animals but are not classified as those posing a significant risk. Category B substances must be handled with care to prevent exposure, and they are subject to specific transportation regulations to ensure safety during movement.

Category A, in contrast, includes substances that are highly infectious and pose a greater risk, requiring more stringent handling protocols. Hazardous Materials is a broader classification that encompasses various dangerous goods but does not specifically apply to the majority of laboratory specimens, which are typically considered less severe than those in Category A. Non-infectious Substances may also be handled without the same level of precaution as laboratory specimens, but this distinction does not accurately categorize the typical laboratory specimens that are indeed infectious but generally considered Category B. Thus, understanding the classification of laboratory specimens is crucial for proper handling and transporting protocols in compliance with regulations.
