Practice areas[ edit ] Risk is ubiquitous in all areas of life and risk management is something that we all must do, whether we are managing a major organisation or simply crossing the road.
When describing risk however, it is convenient to consider that risk practitioners operate in some specific practice areas.In order to understand exactly the impact hazardous waste disposal has on our environment, let’s take a look at what chemicals and hazardous waste actually are, the effects they have in both the short and long term, and what governments are doing about it.
Risk is the potential of gaining or losing something of value. Values (such as physical health, social status, emotional well-being, or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen (planned or not planned).Risk can also be defined as the intentional interaction with uncertainty.
