Exposure = the extent to which someone is subjected to a hazard.





Qualitative risk analysis

 ● Simpler

● Are often used once no precise info concerning possibilities of risk is on the market



Quantitative risk analysis

 ●More Systematic

● Suitable for mathematical analysis

● Provide figures on the (economic) impact of risks

Element of Risk

  1. People
  2. Property
  3. Environment
  4. Mission (business continuity, information)


In this Short YouTube video you will learn the differences between how we define hazards and risks in a Health and Safety context.

Safety control Measures is a very important matter. Its implementation should be done using the following hierarchy order

  1. Prevention Measures
  2. Protection Measures
  3. Mitigation Measures

A prevention measure is to reduce the likelihood of accidents or occupational disease occurrence.


By engineering or technical measures..

  • Remove it
  • Reduce levels of hazardous materials
  • Replace it
