1. Aluminum transit cases offer significant advantages over plastic alternatives in hazmat applications due to their superior cleanability and chemical resistance. The non-porous surface of aluminum does not absorb hazardous substances, enabling thorough decontamination in accordance with OSHA and EPA guidelines, as well as EU hygiene standards for the handling of dangerous goods. Aluminum enclosures also withstand repeated exposure to industrial disinfectants, high-pressure, high-temperature washdowns, and UV sterilization without structural degradation—an essential consideration under U.S. 49 CFR §173.24 and European ADR/RID/IMDG regulations governing the safe containment and transport of hazardous materials. In UN-certified configurations (e.g., 4B, 4BU, 50B), aluminum cases ensure full compliance with both U.S. and EU transport standards, while supporting high operational hygiene—critical in environments requiring stringent contamination control.
