What safety measure should be taken when using a ladder on slippery surfaces?

When using a ladder on slippery surfaces, it is crucial to secure and stabilize it to prevent accidents. Stabilization can involve placing the ladder on a firm, level surface and using stabilizing devices such as ladder stabilizers or outriggers if necessary. This practice increases the ladder's safety and ensures it remains stable under the weight of the user. Slippery conditions pose a significant risk of slipping and falling, making these safety precautions essential for maintaining balance and preventing falls while working at heights. Without proper stabilization, the chances of the ladder shifting or slipping are greatly increased, leading to potential injuries.
