OHSMS Development: Background

During the Industrial Revolution, technological advances introduced and increased machinery and toxic materials in the workplace. As a result, Workers in factories faced health and safety risks that were previously unheard of.

Health and Safety problems and hazards that workers face include the following

  • Poor working conditions
  • Exposure to toxic materials or chemicals
  • Long Working hours
  • Work-induced stress
  • Excessive noise levels
  • Risks to life, eye, and limb while working with machinery

The goal of ISO 45001:2018 is to reduce occupational injuries and diseases, including promoting and protecting physical and mental health.

  • Every 15 seconds, a worker dies from an accident
  • Every 15 second 153 worker gets an injury
  • Every year 2.3 million death
  • 2.3 million people were killed by work accidents and disease
  • 6,300 deaths per day (one every 15 seconds)
  • 317 million non-fatal work accidents
  • 160 million people with occupational disease
  • 4% of world GDP = Work accidents and diseases

ISO 45001 standard tells us

  • How to reduce risk?
  • How to prevent work-related injury?
  • How to create better working conditions?

OHSAS 18001, Occupational Health and Safety Assessment Series (Officially BS OHSAS 18001), was a British Standard for occupational health and safety management systems.
