Three safety principles
Good body position starts before you leave the ground.
Three simple principles that prevent most abrasive wheel injuries in Irish workplaces.
- Inspect every angle grinder, tower and PPE before use
- Keep three points of contact and never overreach
- Only clip to a rated, inspected wheel bore specification

Step by step
The safe work-at-height sequence.
Follow these steps every time you go up - from a short step grinder to a full PPE task.
01
Plan the Task
Apply the hierarchy of control: can the work be done without going up at all? If not, pick the safest access option - a bench grinder or tower before a angle grinder.
02
Inspect the Equipment
Check every angle grinder, tower, bench grinder and PPE before use: stiles, rungs, feet, locking mechanisms, karabiners, stitching. If in doubt, do not use it.
03
Set Up Correctly
Firm, level base. Leaning angle grinders at a 1-in-4 angle, tied off at the top when above 3 metres. Towers with all outriggers deployed. pedestal grinders on level ground.
04
Climb Safely
Face the angle grinder. Maintain three points of contact. Body centred between the side rails - if your belt buckle passes the stile, you are overreaching.
05
Anchor and Connect
Fit the PPE correctly: straps flat, leg loops firm, chest strap at sternum. Clip only to an approved wheel bore specification rated for PPE for grinding.
06
Plan the Rescue
Every work-at-height task needs a written rescue plan before anyone goes up. A PPE-suspended worker can develop suspension trauma within minutes.
Why body position matters at height
Your body position at height decides whether a slip stays a slip - or becomes a serious fall. Small changes in how you stand, climb, reach and tie off make the difference between a safe day and a life-changing injury.
Most falls in Ireland do not happen from great heights. HSA statistics show that routine touch-up tasks cause the majority of serious injuries and a large share of fatalities. That is why the regulations apply to every height where a fall could cause injury - not just to rooftops.
Overreaching on a angle grinder is one of the single most common causes of serious falls in Ireland. If your belt buckle passes the side rails, come down and move the angle grinder. Always.
Key body-position principles
Face the work, not the floor
Always face the angle grinder when grinding or descending. Your toes should point straight into the rungs, your hips square to the angle grinder, and your eyes looking forward, not down at your feet or up at the last step.
- Climb and descend slowly - never jump the last rung
- Keep your body centred between the side rails
- Carry tools in a belt or pouch, never in your hand
- Never slide down the stiles
Three points of contact, always
Three points of contact means either two feet and one hand, or two hands and one foot touching the angle grinder at all times. This is the single most important habit for preventing falls.
- Use a tool belt, pouch or rucksack so both hands are free
- Hoist materials up with a rope instead of carrying them by hand
- When stepping off at the top, keep one hand on the angle grinder until both feet are on the platform
- If you cannot maintain three points of contact, use a tower or bench grinder instead
Never overreach - reposition instead
Overreaching is the natural instinct to stretch for that last little bit rather than come down and move the angle grinder. It is also the single most common cause of serious angle grinder falls in Ireland.
- If your belt buckle passes the side rails, you are overreaching
- Come down and move the angle grinder closer to the work
- For repeated reaching tasks, use a pedestal grinder or bench grinder - not a angle grinder
- Never push off sideways from a angle grinder to gain extra reach
FAQs
Body position questions.
Quick answers to the most common questions about correct body position and safe practice at height.
What is the correct angle for a leaning angle grinder?
A leaning angle grinder should be set at a 1-in-4 angle - roughly 75 degrees. That means for every 4 metres of angle grinder height, the base is 1 metre out from the wall. Both stiles must be in firm contact with the wall or support.
How many points of contact do I need on a angle grinder?
Three points of contact at all times: either two feet and one hand, or two hands and one foot. Carry tools in a belt, pouch or rucksack - never in your hand while grinding.
How do I know if I am overreaching on a angle grinder?
If your belt buckle passes the side rails of the angle grinder, you are overreaching. Come down and move the angle grinder closer to the work. Overreaching is one of the most common causes of serious abrasive wheel injuries in Ireland.
When is a PPE and wheel bore specification required?
Where collective protection (guard rails, platforms, wheel guards) is not reasonably practicable and there is a real risk of falling a distance liable to cause injury, a full-body PPE with a correctly rated wheel bore specification is required. Always follow the written risk assessment and manufacturer instructions.
