CSCS IRELAND Study Guide 2026

Under Irish construction regulations, guardrails on scaffold platforms must be at least 950 mm high, with a mid-rail and toe board also required to prevent falls and objects being kicked off.

Selecting tools with lower vibration emissions and keeping them properly maintained (sharp blades, correct settings) directly reduces the vibration at source, which is more effective than downstream controls.

A thorough accident report captures all factual information needed to investigate and prevent recurrence. Incomplete records hinder investigation and may be inadequate for legal proceedings or HSA notification.

Emergency drills should be conducted regularly — at least twice per year on longer-duration projects. Additional drills should be held when: the site layout changes significantly (affecting escape routes), new significant hazards are introduced, a large number of new workers arrive, or the emergency plan is revised. Drills must be recorded, and any issues identified must be corrected.

Before entry into a deep excavation, a competent person must inspect for stability, test the atmosphere for gas accumulation (especially in confined-space-like conditions), provide proper access/egress ladders, and have an emergency rescue plan.

The correct angle for a leaning ladder is approximately 75 degrees, following the 1 in 4 rule: for every 4 metres of vertical height, the base should be 1 metre away from the wall.
