What safety measures should be taken when installing a hand rail for steps?

When installing a handrail for steps, it is important to ensure that the handrail is securely anchored to the wall or posts, at a height of 34-38 inches above the steps. The handrail should be continuous along the entire length of the steps, with a smooth surface and rounded edges to prevent injury. Additionally, the handrail should be able to support a person's weight and be easy to grip.
