Most scaffold failures are simple: a missing brace, a base plate on soft ground, a plank borrowed for something else.
Walk around it with this list before anyone climbs. It takes five minutes.
Start at the bottom
Nearly every bad collapse starts here.
- Base plate under every standard. This is a legal requirement, not a preference.
- Sole boards on soft ground, fresh backfill or anything not solid and level.
- No packing on loose blocks, drain pipes or chimney pots — these are banned as supports.
- Base level, standards plumb or leaning slightly toward the building.
- No ground washed away or dug out near the base since it went up.
- Nothing stacked against it and no vehicles swinging near it.
Check the structure
- Every brace fitted. Missing braces are the most common serious fault.
- Tied to the building at the right spacing, with no ties cut out for access.
- Couplers the right type, properly seated and tight.
- Standards straight, ledgers level. Any visible lean means stop.
- Nothing missing, improvised, or mixed between different systems.
- No bent, split or badly rusted parts. Damaged gear comes out, it does not get turned around.
Platform and ladder
These rules kick in wherever someone could fall more than 6 ft 6 in (about 2 m).
- Platform fully boarded, no gaps.
- Wide enough: 25 in to stand on, 34 in if material is stacked on it, 42 in if it holds a platform above.
- Boards at least 8 in wide, sitting flat on at least three supports.
- Guard-rails at least 3 ft 6 in above the platform.
- Toe boards at least 6 in high, and no more than 30 in from the toe board up to the lowest rail.
- Rails and toe boards fixed inside the uprights so they cannot be pushed off.
- Gap to the building no more than 12 in.
- Ladder tied at the top, firm level footing, sticking up 3 ft 6 in above the landing. Nobody climbs the frame.
- Deck clear of rubbish, offcuts and standing water.
Rails can come off to move material through — for that job, and then straight back on.
Weather here is the difference
- Hurricane season — sheeting turns a scaffold into a sail. Plan to strip it before a named storm.
- Heavy rain — the danger is under the scaffold. Rain softens ground and washes out around base plates.
- Salt air — corrosion hits couplers and threads first, where you cannot see it.
- Heat — tired crews take shortcuts at height. Do the high work early.
When to check it again
The law is specific here. A scaffold cannot be used unless a competent person has inspected it in the last seven days, and again after any weather that could have affected it.
Also check it again after:
- Any change to it, including a brace or tie taken out.
- Any knock from plant, a vehicle or a dropped load.
- Any spell where it stood unused.
- Before your crew uses a scaffold that was put up for somebody else.
Write it down and sign it. A verbal "it looked alright" is not an inspection record. And if a scaffold is left part-dismantled, it needs a warning notice at every access point.
Stop work if you see this
- Any lean, sway or movement under load.
- A standard hanging clear of its base plate.
- Missing braces or ties, or ties that have been cut.
- Gaps in the platform, or missing rails and toe boards.
- Water ponding or running around the base.
- People climbing the frame because the ladder is short or unsecured.
Faulty parts come out of service. If that leaves you short, our scaffolding is inspected before it leaves the yard.
What the law says
Scaffolding here falls under the Building Operations and Works of Engineering Construction (Safety, Health and Welfare) Regulations, made under the Factories Act in 1968 (L.N. 214/68). The main duties:
- A competent person must supervise every erection, alteration and dismantling.
- Material must be checked by a competent person before each use.
- Metal parts must be free of corrosion that weakens them; timber must have bark off and be unpainted so faults show.
- Every scaffold must be braced and tied unless designed to stand without ties.
- Mobile towers: firm level ground, weighted if needed, secured while in use, pushed only from the base.
- Inspection every seven days and after weather, with a signed written record.
- Anyone who spots a fault must report it to their employer or foreman without delay.
| What | Minimum | Metric |
|---|---|---|
| Fall height that triggers the rules | 6 ft 6 in | ≈ 2.0 m |
| Guard-rail height | 3 ft 6 in | ≈ 1.07 m |
| Toe board height | 6 in | ≈ 150 mm |
| Toe board to lowest rail | 30 in max | ≈ 760 mm |
| Platform width — standing only | 25 in | ≈ 635 mm |
| Platform width — with material | 34 in | ≈ 865 mm |
| Board width | 8 in | ≈ 200 mm |
| Gap to the building | 12 in max | ≈ 305 mm |
| Ladder above the landing | 3 ft 6 in | ≈ 1.07 m |
| Inspection interval | Every 7 days | — |

Common questions
- How often must scaffolding be inspected in Jamaica?
- Every seven days by a competent person, and again after any weather that could have affected its strength or stability. Each inspection must be written down and signed.
- How high do guard-rails and toe boards have to be?
- Guard-rails at least 3 ft 6 in (about 1.07 m) above the platform, and toe boards at least 6 in (about 150 mm). No more than 30 in between the toe board and the lowest rail.
- Who can put up scaffolding on a site?
- It must be erected, altered or taken down under the immediate supervision of a competent person, by workers with proper experience. The material must also be checked before each use.
- What should I check after heavy rain?
- Start at the base. Look for water ponding or running around the standards, washed-out ground, and sole boards that have sunk or shifted. Then check it is still standing plumb.
