Guardrails

  • Guardrails must be at least 1100 mm height. This parameter is measured vertically from the ground level, to the highest point of the guardrail.
  • The guardrails must have sufficient strength and stiffness to withstand a horizontal uniformly distributed force of 3.0 kN/m.
  • The guardrails cannot be easily climbable.
  • Openings on guardrails shall not allow a 100 mm diameter sphere to pass through.
  • When guardrails are installed to protect slopes, they must have a continuous base in their entire length from the floor surface to a minimum height of 100 mm.

Glossary of Terms

Pendulum test value (PTV) is a measurement of the slip resistance of a floor surface, either an external or internal floor of a building. The least slip resistance a surface material is, the more likely people may skid or trip, especially in wet conditions. In average circumstances, slip-resistance is as follows:

0-18 = very low slip-resistance.

18-25 = moderate slip-resistance.

25-36 = good slip resistance.

Light Reflectance Value (LRV) is a numeric scale that is used to identify how much light a colour reflects or absorbs. It is used in universal design to identify the contrast between two colours. This can help to determine if there is sufficient contrast to visually identify a feature such as a fonts on a sign, elevator call button, a handrail and other items which need to be seen by visually impaired people.

A strong bar, fence, railing, balustrade or glass constructed as part of building along side a drop or something steep, such as slopes, stairs, balcony edges, external paths or terraces. They are suitably strong to prevent people from tripping or falling off causing harm.

Kilonewtons (kN/m), is the measurement of pressure or force. In universal design, we use kN/m to measure the pressure resistance of floors, the force needed to open doors or the force used against guardrails.
