The job hazard analysis
PPE required: Hard hat, Safety glasses, Gloves, Safety boots, Fall arrest harness
1. Plan the install
What could go wrong
Collapse from poor bracing; wind
How we control it
Follow the truss maker's bracing plan. Don't set trusses in high wind.
2. Lift
What could go wrong
Dropped or swinging trusses
How we control it
Use rated rigging and a crane or telehandler. Keep people out from under the load. Use tag lines.
3. Set and brace
What could go wrong
Falls from the wall plate; trusses toppling
How we control it
Use fall protection or a work platform. Fasten and brace each truss before releasing the next.
4. Install permanent bracing
What could go wrong
Working on unbraced trusses
How we control it
Complete bracing in the order in the plan. Don't walk on trusses that aren't fully braced.
- Trusses that aren't braced can fall like dominoes. Install bracing as the plan says.
When to use it
Use it before truss work, and review it when span, weather, or lifting method changes.
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.
