The job hazard analysis
PPE required: Hard hat, Safety glasses, Gloves, Safety boots, Respirator or mask
1. Set up materials and scaffold
What could go wrong
Strains; overloaded platforms
How we control it
Place blocks within reach on a stable platform. Stay within the scaffold load rating.
2. Lay the courses
What could go wrong
Falling blocks; mortar burns; cuts
How we control it
Wear gloves and eye protection. Keep the edge clear. Cut with a wet saw or dust extraction.
3. Brace the wall
What could go wrong
Wind collapse of freshly built walls
How we control it
Brace walls as the engineer or standard advises, especially in wind. Keep people clear of the fall zone.
4. Clean up
What could go wrong
Mortar splashes and dust
How we control it
Keep areas clear and wet down dust.
- A freshly built wall hasn't developed strength. Keep people and equipment away from the fall zone until it's braced.
When to use it
Use it for masonry work, and review it when wall height, bracing, or scaffold needs change.
Review it with the crew before the work starts, change anything that doesn't match how you'll do the job, and update it when the method, the equipment, or the site changes.
Use this JHA in Reldro
- It arrives ready to edit, and your crew uses it on their phone, even without signal.
- Failed items become corrective actions with an owner and a due date.
- Every completed one is kept with the site, the date and who did it.
