THE JOB
Cycling a flytable / flyform floor to floor. Method: GOSPEL-SWP-028. Fill GOSPEL-SJP-001 / FRM-052 for this cycle. This page is what can go wrong in drop, roll, fly and land. Formwork carpentry is the host’s hazard analysis, not this one.
WHO IS EXPOSED
- Operator
- Rigger and signalperson
- Formwork crew at the drop and the landing
- Spotters on both floors
- Anyone below the path
- Prime — not a spectator
A JHA names what can hurt someone and how that risk is controlled. It is not the procedure. Do the work to the matching SWP. WorkSafeBC does not prescribe a JHA form — the Workers Compensation Act s. 21(2)(b) requires workers to be made aware of known or reasonably foreseeable hazards. This is how GOSPEL does that for this job.
HAZARDS AND RISK
Task is the work being analysed — not a procedure to follow. Controls follow the hierarchy: eliminate, substitute, engineer, administer, PPE last. The badge is how bad this task going wrong is in this job. Extreme is the killer with no recovery. High is serious injury or a dropped load you still have a chance to stop. Moderate is lost time or a plan that failed. Low is first aid.
LOWMODERATEHIGHEXTREME
| TASK | HAZARD | RISK | CONTROL |
|---|---|---|---|
| Gate / plan | Last floor’s SJP, missing drawing, no pre-lift meeting | HIGHCritical lift run as a grocery pick. The incidents WorkSafeBC filmed. | This-cycle SJP. Drawing revision. Meeting close to the lift. GOSPEL-SWP-019 and 028. |
| Drop | Table still snagged. Crane used to strip. People under the table. | HIGHSudden load, structural damage, crush. Host duty under Part 20 — the crane does not take load to drop jacks. | Formwork drops per OEM. Crane on standby. Zone clear. Confirm free of the slab before any hoist. |
| Roll to the edge | Runaway table. Fall from the unguarded slab. Crane pulling the table out. | EXTREMETable over the edge. Person over the edge. Side-load on the crane. Fatal. | Curb stops, kicker blocks, brake lines as the drawing. Part 11 at the edge. Crane does not pull. Aluma / Doka: guide out, do not drag. |
| Attach | Wrong pick, missing pin or cotter, two points on a four-point table, people still on it | EXTREMETable dumps when it leaves the slab. Dropped load. 14.44. | Every designated point, pins in as the OEM, before the table leaves the building. Doka: four designed points before travel outside. People and loose material off. |
| Fly | Wind on a panel. Lost radio. Shifting COG. Falling objects. | HIGHUncontrolled swing, contact, struck-by on the floors below. | Lower wind number wins. Confirmation-loop radios. Tag lines. Tethered tools, exclusion, catch nets as the site plan. Stop on change. |
| Land | Disconnect before the table is stable. Crush at the set. | HIGHTable walks, tips, or drops a bay. Hands in the pinch. | Jacks or landing dollies as the OEM. Tiebacks and curbs as the drawing. Formwork supervisor says landed. Then release. |
| Change | Sequence drift, different table, weather pickup, new person on the radio | HIGHThe unbriefed change is the incident. | Stop and discuss. Engineer if the drawing no longer matches. Rewrite the SJP. Do not adapt on the fly. |
RESIDUAL RISK
A table still moves when a pin is missed, a radio is lost, or the COG is not the drawing. Residual is held by the gate, by confirmation loops, and by stop-work — not by having flown this building yesterday. 14.42.1.
THE JOB DOES NOT PROCEED IF
- No engineered drawing or manufacturer cycle at the lift
- Weight or COG unknown (14.36)
- This is a corner or nontypical table without GOSPEL-SWP-029
- Crane being asked to pull the table out
- People or loose gear on the table
- Radios not confirmed on both floors
- Wind above the lower limit
PPE — LAST LINE
- Hard hat
- CSA-grade footwear
- High-visibility clothing
- Eye protection
- Task-rated gloves
- Hearing protection where required
- Fall protection where the work exposes a fall
