Toolbox: 99%

Let’s be honest here. Is it really necessary to have an accident or even an incident free job site? Isn’t 99.9% accident free good enough?


To make our point clear, several examples are listed exhibiting what life would be like if things were done correctly 99.9% of the time.


99.9% means….

  • We would drink 1 hour of unsafe water each month
  • There would be 2 unsafe plane landings per day at O’Hara International Airport in Chicago.
  • There would be 20,000 incorrect drug prescriptions given every year.
  • Doctors would drop 50 newborn babies at birth every day.
  • 500 incorrect surgical operations would be performed each week.
  • 22,000 cheques would be deducted from the wrong bank account each hour.
  • Your heart would miss 32,000 heartbeats each year.


99.9% safe doesn’t sound very safe, does it? Suddenly, the quest of ZERO makes more sense.
