Containment
Risk containment: Containment
If planned Risk Prevention were not sufficient and an emergency occurs despite precautionary measures, the first objective is to contain and control the negative consequences of this event in order to avoid a crisis.
Analysis according to the HAZOP method
- If a critical deviation ("orange") occurs, how can the consequences for employees, the company and the environment be reduced?
- What technical means (pressure relief valves, escape doors, etc.) are available for this purpose?
- What organisational means are available for this?
Examples from practice
- If a leak occurs in a petrol tank, it is possible to prevent petrol from escaping freely into the environment by placing a protective sump under the tank. The emergency (leak at the tank) occurs, but no crisis situation arises. The consequences can be controlled and the problem can be solved safely (petrol is collected and the tank repaired).
- If a panic occurs in an event building, adequately marked escape routes and escape doors that are easily identifiable, even in the event of a power failure, are available.
However, if a condition is reached in which the emergency is so extreme that the planned containments are no longer sufficient, e.g. due to explosions or damage to relevant auxiliaries, the "red" phase, the Emergency Management, initiated.
Containment
Containment, i.e., the containment of risks, should take the following points into account:
Planning of measures for containment
Reduction of consequences in case of occurrence of critical deviations from the target
- Preventing the deviation from becoming an emergency or crisis
