Report Topics:
What are the dimensions of environmental uncertainty?
Focus on the dimensions of environmental uncertainty and its degree of complexity, or the number of
different factors in the environment. An environment is typically classified as relatively simple or
complex. Also highlight on the rate of change in and among these factors. An environment is typically
classified as stable or dynamic. In your report, remember that the most challenging and uncertain
situation is an environment that is both complex and dynamic. High-uncertainty environments require
flexibility and adaptability in organizational designs and work practices, as well as an ability of decision
makers to respond quickly as new circumstances arise and new information becomes available.

Question 1 [……. /6 Marks]

Below you will find a non-exhaustive list of three hazards that can be found in a range of work environment.

Based on the given description, you will use the table below to present the risk assessment study

 

  • Give the types of hazards and place them in the first column. You will get three different types.

 

  • Assess the risk using the qualitative and a quantitative risk assessment matrix. For each hazard (answer the questions below:)
  • What can go wrong?
  • What is the likelihood that it would go wrong?
  • What are the consequences (impact)?

Decide on control measures: select Tow of the five known risk management approaches (refer to the hierarchy of control) and assess the residual risk (R2).

 

List of Hazards:

  • Possible exposure to electrical live parts can result in major injuries leading to death, including electric shocks, burns, explosions and falls from height. The risk is increased in wet conditions, where a worker’s equipment and surroundings can also become live.

 

  • Viruses, bacteria, insects, animals, etc., are likely to cause adverse health impacts. These health impacts can range from skin and respiratory system irritation, to the transmission of infections. This will require professional intervention and time off work for 5days.

 

  • Unguarded machinery or unguarded moving machinery parts presents a serious danger as employees can sustain serious injury and fatalities leading to long term disabilities if they unlikely were to accidentally come into contact with them.

  • Human mistakes due to lack of:
  • Experience
  • Training
