# Halt and delete chaos experiment

This topic describes how to halt an experiment and how to delete an experiment.

### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

* [Create Experiment](/resilience-testing/chaos-engineering/chaos-experiments/create-experiments.md)
* [Run or Schedule Experiment](/resilience-testing/chaos-engineering/chaos-experiments/run-experiments.md)
* [Edit or Update Experiment](/resilience-testing/chaos-engineering/chaos-experiments/edit-chaos-experiment.md)

Halting the execution of a chaos experiment protects target applications from any unwanted and unforeseen consequences by immediately stopping the experiment and reverting the target resources to their initial state.

Halting a cron experiment disables it, preventing it from executing according to its cron schedule in the future.

### Halt an Experiment <a href="#halt-an-experiment" id="halt-an-experiment"></a>

1. To halt an experiment execution, select its name from the list of experiments on the **Chaos Experiments** page. Click the `🚫` icon. The experiment's status will update to `Stopped`.

2. If you need to halt multiple experiments simultaneously, go to the **Chaos Experiments** page and click **Stop All Experiments**. This will stop all currently executing experiments.

### Delete an Experiment <a href="#delete-an-experiment" id="delete-an-experiment"></a>

Deleting an experiment removes it from the **Chaos Experiments** list under the **Chaos** tab. Deleting an experiment that is currently running will not only stop it immediately but also permanently remove it. To delete an experiment, click the **`⋮`** icon next to the experiment name and select **Delete Experiment**.

**NOTE**

* Deleting an initialized or completed experiment will permanently remove it.
* Deleting a running experiment will both stop the execution and permanently remove the experiment.
* Deleting an experiment does not delete any templates created from that experiment.
  {% endhint %}

#### Delete Multiple Experiments <a href="#delete-multiple-experiments" id="delete-multiple-experiments"></a>

* You can delete multiple experiments by selecting it from the **Chaos Experiments** page and clicking the **Delete** button.

* Confirm by clicking **Delete**.
