Standards for mobile towers
The document discusses standards for mobile access towers in the UK. It describes the Prefabricated Access Suppliers and Manufacturers Association (PASMA) as the recognized authority for mobile towers. The EN1004 standard requires towers to have guardrails, trapdoors, toe boards, built-in access, stabilizers, and instructions. Non-compliant towers may be missing these key safety features. The document also outlines inspection checklists to ensure towers are properly assembled and stabilized before use.
