Difference Between NEBOSH, IOSH, and OSHA  

Although NEBOSH, IOSH, and OSHA deal with health and safety in the workplace, there are many differences between them. It is essential to know these differences as they can provide clarity when choosing one. Some of their differences are listed below:  

a) NEBOSH certifications equip students with the knowledge and abilities to manage safety and health at work. They enhance productivity and reduce injuries, illnesses, and related expenses. NEBOSH doesn't directly offer courses; however, it creates the syllabus and establishes evaluation methods like coursework and exams. The institutes accredited by NEBOSH can offer its courses. NEBOSH courses are suitable for managers, supervisors, and anyone responsible for managing health and safety in the workplace. 

b) OSHA and IOSH are suitable for employees or team members who need to implement health and safety procedures in their everyday working environment. OSHA is a federal agency that regulates workplace safety and health in the United States. Its guidelines provide the foundation of workplace health and safety programs. Employers who fail to comply with OSHA standards are subject to a variety of penalties and fines. OSHA also provides technical assistance and information to employers, employees, their families, and safety professionals. The problem with OSHA, though, is that it has geographical restrictions and is only available to those who live in the US. Since 2010, the debit card-sized card received upon successfully completing OSHA is also limited to candidates from the US. 

c) IOSH is a research agency that promotes workplace safety and health. IOSH credentials are based on both theory and practice and give students the chance to gain real-world experience.
