The Matrix Model was first introduced in 1850 by James Joseph Sylvester.
The Matrix Model was invented in 1857/1858 by Cayley.
Risk assessment is the process of evaluating risks to worker’s safety and health, and assets from workplace hazards. It is a systematic examination of all work that considers:
- What could cause injury or harm
- Whether the hazards could be eliminated and if not
- What preventive or protective measures are or should be in place to control the risks
What Is The Purpose Of A Risk Assessment?
Risk Assessments Objectives:
1. Identification Hazard
2. Conduct Risk Assessment
c) Engineering work
d) Administrative work
4. Accept The Risk
How to conduct a risk assessment
A risk assessment can be carried out in a variety of ways. What is most important is that you:
- Determine the dangers.
- Determine who may be damaged and how.
- Determine the hazards and the steps that must be done to eliminate or lessen the risk.
- Make a note of your observations and put them into action.
- Examine your assessment and, if necessary, amend it.
Only “significant” findings must be recorded. Don’t make the process too complicated. Most firms are aware of the hazards, and the necessary control mechanisms are simple to implement and likely already in place.
A risk assessment does not require you to be a health and safety specialist. If you own a small business and are satisfied that you understand what’s required, you can complete the assessment yourself or ask a competent employee or colleague to do it for you, but remember that you are responsible for ensuring that the evaluation is done correctly.

Quantitative Risk Assessments Formula
Risk = Probability (P) x Consequence (C)
Risk Score = P x C
Risk Prioritization – Likelihood and Impact
Likelihood of a risk event occurring (P)
- Very High: is almost certain to occur = Point-5
- High: is likely to occur = Point-4
- Medium: is as likely as not to occur = Point-3
- Low: may occur occasionally = Point-2
- Very Low: Unlikely to occur = Point-1
Risk Impact (C)
- Very High: Ultimate threat = Point-5
- High: Substantial impact on the cost or safety = Point-4
- Medium: Notable impact on time, cost, or safety = Point-3
- Low: Minor impact on time, cost, or safety = Point-2
- Very Low: Negligible impact = Point-1
