Hazards and Risks Definition

Hazard Is

  • – Anything that may cause harm (e.g. chemicals, electricity, working at height, etc)
  • – A hazard is any potential damage, harm, or adverse effects source.
  • – Hazard is a situation that poses a level of threat to life, health, property, or environment.

Risk Is

  • – The chance (high or low) that someone is injured by the hazard.
  • – Risk is someone or something that creates or suggests a hazard.
  • – Risk is a possibility of danger or harm.

Hazard = any potential adverse health effect, harm, or damage source.

Risk = the likelihood that a person exposed to a hazard will be harmed.

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




Qualitative risk analysis

 ● Simpler

● Are often used once, with no precise info concerning possibilities of risk


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.

What Is The Basic Concept Of Safety?

Safety: The state of being safe, exempt from hurt or injury, and freedom from danger in safety.

We can call it,

Safety = Awareness + Preparation


Area of Safety in the Workplace, School, and Home


Building and Structural Safety – Safety in general including installation as per existing building code and expert engineer.


Environment Safety – Issues of environmental safety (direct or indirect impact on the school, home, and industry).


Material or Equipment Safety – Safety of the materials used in the production or others.


Workplace Safety – Safety issues directly associated with the workplace.


Fire Safety – Fire safety, specifically, the risks associated with the school, home, and industry.


Electrical Safety – generally and above all, arising from the instrumentality used.


Safety Control Measures

Safety control Measures are 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
