Cornice Installation

A SWMS is required for high-risk construction work under WHS Regulation. Cornice installation becomes high-risk when there is a risk of falling more than 2 metres (e.g., high ceilings, stairwells). Even for standard height work, a SWMS is recommended best practice and may be required by the principal contractor.

A platform ladder is the safest option for standard ceiling heights — it provides a stable platform with guardrails. For extended runs, use a trestle and scaffold plank system. Avoid using stepladders for prolonged overhead work. Scaffolding is required for ceilings above 3.6m. Plastering stilts are only for experienced operators on flat, even surfaces.

Minimum P2 dust mask (AS/NZS 1716) for all cutting and sanding operations. Use a half-face respirator with P2 filters for extended sanding. Fit-testing is required for tight-fitting respirators (AS/NZS 1715). Wet cutting or dust extraction at the saw reduces airborne dust significantly.

Plastering stilts can be used by experienced operators on flat, even floors only. They must never be used on scaffolding, stairs, ramps, or near open edges. Maximum height is per manufacturer rating. Check state-specific regulations — some jurisdictions have additional restrictions on stilt use.

Yes. Cement-based cornice adhesive is alkaline (pH 12-13) and is classified as causing serious eye damage (Category 1) and skin irritation (Category 2). Always wear gloves and safety glasses when mixing and applying. If adhesive contacts eyes, irrigate with clean water for minimum 15 minutes and seek immediate medical attention.

Use T-braces or cornice props to support lengths while adhesive sets. Two-person operation for lengths over 2.4m or heavy profiles. Rotate between overhead and ground tasks every 30-45 minutes. Adjust platform height to minimise reaching distance. Take regular breaks and stretch shoulders and arms.

Buildings constructed before 2003 may contain asbestos in existing cornice, ceiling sheets, or wall linings. If removing or disturbing existing cornice in pre-2003 buildings, have a competent person assess for asbestos before work begins. If asbestos is confirmed, engage a licensed asbestos removalist.

Mitre saws generate 90-100 dB(A), exceeding the 85 dB(A) exposure standard. Class 4 or 5 earmuffs (AS/NZS 1270) are required during mitre saw operation. Hearing protection should also be worn within 3m of the operating saw. Batch cutting reduces total exposure time.

Inspect ladders before each use. Check for bent rungs, cracked stiles, missing feet, loose rivets, and damaged platforms. Reject any ladder with visible damage. Industrial-rated ladders (minimum 120kg) compliant with AS/NZS 1892 must be used. Platform ladders should have functional guardrails and locking mechanisms.

Gypsum cornice is lightweight (2-4kg per length) with moderate dust risk. Fibrous plaster is heavier (4-8kg) requiring two-person handling for large profiles, and may contain glass fibre. Polystyrene/foam cornice is very lightweight with minimal manual handling risk but melts if in contact with certain adhesives. Always check SDS for specific product hazards.
