The World Day observed on April 28th is known as "Workers' Memorial Day" or "International Workers' Memorial Day". It is a day to commemorate workers who have been killed, injured, or suffered from illness due to their work.

The day was first recognized in 1984 by the Canadian Union of Public Employees to honor workers who died or were injured on the job. Since then, it has been recognized internationally and is now observed in more than 100 countries around the world.

On Workers' Memorial Day, people come together to remember those who have lost their lives or been injured at work, and to raise awareness about the importance of workplace safety and health. It is a day to renew the commitment to improving workplace safety and to strive for safer and healthier working conditions for all workers.

ISO 45001 is a globally recognized standard for occupational health and safety (OH&S) management systems. It provides a framework for organizations to manage and continuously improve their OH&S performance and prevent work-related injuries, illnesses, and fatalities. Here are some reasons why ISO 45001 is important in the industry:

1. Protecting workers: The primary purpose of ISO 45001 is to protect workers' health and safety. By implementing this standard, organizations can identify and manage occupational health and safety risks, promote worker participation and consultation, and create a safe and healthy work environment.

2. Legal compliance: Compliance with ISO 45001 can help organizations meet legal and regulatory requirements related to OH&S. This can help them avoid legal penalties, lawsuits, and damage to their reputation.

3. Improved business performance: By implementing ISO 45001, organizations can reduce workplace incidents, improve productivity, and decrease absenteeism and turnover due to injury or illness. This can lead to improved business performance and a better bottom line.

4. Enhanced reputation: Implementing ISO 45001 demonstrates an organization's commitment to worker health and safety. This can enhance its reputation with stakeholders, including customers, investors, and employees.

5. Competitive advantage: ISO 45001 certification can provide a competitive advantage by demonstrating that an organization has effective OH&S management systems in place. This can help it win new business and maintain existing relationships with customers who prioritize safety.

Overall, ISO 45001 is important in the industry because it helps organizations protect workers, comply with legal requirements, improve business performance, enhance reputation, and gain a competitive advantage.
