Occupational Health and Safety (OH&S) management is an essential function in every organization, regardless of its size or industry. From manufacturing plants and construction sites to healthcare facilities and corporate offices, ensuring a safe and healthy workplace is critical for protecting employees, maintaining legal compliance, and achieving sustainable business growth.
At the heart of every effective Occupational Health and Safety Management System (OHSMS) is the Occupational Health & Safety (OH&S) Manager. This professional is responsible for identifying workplace hazards, implementing safety controls, promoting employee well-being, ensuring compliance with applicable legislation, and driving continual improvement in occupational health and safety performance.
