Long-term exposure to physical, chemical, and ergonomic hazards can pose significant health risks to workers and may even lead to occupational diseases. To assist businesses in identifying risks and improving workplace conditions, COAPRE has invited representatives from various organizations to share their practical improvement measures and implementation experiences. By exchanging successful case studies, this handbook aims to help businesses strengthen their workplace environment management, enhance occupational health protection, and foster industry-wide knowledge sharing and learning. The case studies provided in this handbook are for reference purposes only. The suggested improvement measures are not the sole solutions, nor do they constitute an endorsement of specific service providers.
