Today, we'll discuss the important role handrails play on ramps and stairs. Who can tell me why handrails are important?

Noah
Noah

They help people climb stairs safely!

Sarah
SarahInstructor

Exactly! Handrails provide necessary support, especially for those with mobility challenges. What heights should handrails be mounted at?

Isabella
Isabella

They should be between 850 mm and 900 mm above the ramp or stair!

Sarah
SarahInstructor

Good job! This ensures that most users can easily grip the handrails. Remember this height by the acronym HEM—'Handrail Height Makes.' Let’s dive deeper into how we install these handrails properly.

Now, let’s look at the design requirements for handrails. Who remembers where handrails should be placed on ramps?

Akash
Akash

On both sides of the ramps and stairs!

Robert
RobertInstructor

Correct! Why do we install them on both sides?

Ananya

So everyone has support, no matter which side they hold onto!

Robert
RobertInstructor

Exactly! And they should extend beyond the ramp or stairs by at least 300 mm. This extension is critical. Remember the mnemonic LEE—'Long Enough Extensions.'

Let’s discuss the grip shape and sizes for handrails. What should be the diameter for circular handrails?

Noah
Noah

Between 32 mm and 40 mm!

Sarah
SarahInstructor

Great! Can anyone tell me about non-circular handrails?

Isabella
Isabella

Their perimeter should be between 100 mm and 125 mm!

Sarah
SarahInstructor

Excellent! Remember, we need at least 40 mm of clearance between the handrail and the wall—think of it as 'Room for My Hand'—a memory phrase. Let's wrap up with why these specific shapes matter.
