The following safety precautions should be taken when conducting the reaction between potassium and water:

* **Always wear appropriate personal protective equipment (PPE)**, including safety glasses, chemical gloves, and a laboratory coat.
* **Conduct the reaction in a well-ventilated area** or under a fume hood.
* **Use small amounts of potassium and water** to minimize the risk of a violent reaction.
* **Add the potassium to the water slowly and carefully**, and avoid splashing.
* **Be prepared to extinguish any fires** that may occur.
* **Have a spill kit available** in case of an accident.

It is also important to note that the reaction between potassium and water can produce hydrogen gas, which is flammable. Therefore, it is important to avoid open flames or other ignition sources in the area where the reaction is being conducted.

If you are not trained in chemistry or do not have experience handling hazardous materials, it is best to avoid conducting this reaction altogether.

Here are some additional safety precautions that may be taken:

* **Work under an inert gas**, such as nitrogen or argon. This will help to prevent the potassium from reacting with oxygen in the air.
* **Use a glove box** to prevent contact with the potassium and water.
* **Use a remote manipulator** to handle the potassium and water.
* **Have a fire extinguisher** and a spill kit readily available.

It is also important to have a plan in place in case of an emergency. This plan should include procedures for evacuating the area, extinguishing fires, and cleaning up spills.
