Organization: IOSH is the world's largest chartered professional body for health and safety practitioners, based in the UK with global recognition.

Purpose: IOSH sets standards, provides guidance, and offers a range of training courses to improve workplace safety and health across all sectors and levels.

Target Audience: IOSH courses are typically aimed at line managers, supervisors, and employees who need a practical understanding of health and safety in their daily roles, rather than those seeking a full-time career as a safety professional.

Key Courses: The most popular courses are "IOSH Working Safely" (for all employees) and "IOSH Managing Safely" (for managers/supervisors), which cover risk assessment, hazard identification, and legal responsibilities.

Level: IOSH Managing Safely is an internationally recognized, entry-level qualification (roughly equivalent to a UK Level 2 qualification or GCSE level).
