NO VERIFIED CONTROL = NO AFFECTED WORK. No affected task starts or continues while a required critical control is missing, ineffective or unverified.
SCS is a scaffold user, not an erector: no erection, alteration or dismantling. Asbestos removal/remediation, electrical/plumbing/gas/structural work, hot work, confined-space entry, excavation and road-corridor traffic design are outside the current representative scope. Roof access is separately scoped and agreed. Conditional standards do not authorise excluded work.
Conditional scope: MEWPs, roof/fragile-surface exposure and pressurised spray apply only when relevant and separately approved. Match the selected sheets to the actual SCS work order and agreed scope.
Field standard index
Each sheet opens at its page in the approved PDF
- SCS-HS-CRS-01
01 · Working At Height
Ladders, platforms, edges, stairs and elevated finishing work
Falls between levels during preparation, plastering and painting; falling tools and materials may seriously injure people below. Assess all fall exposures, including low-level work.
Stop work: Unsafe ladder or platform; missing edge protection; unverified anchor; no workable rescue; occupants in drop zone.
Open sheet (page 5) - SCS-HS-CRS-02
02 · Scaffold User Safety
Main Contractor supplied scaffold - SCS is a scaffold user
Collapse, falls or dropped materials from incomplete, altered, overloaded or poorly supported scaffold. Supply by another PCBU does not remove SCS user checks.
Stop work: Incomplete or out-of-date release; removed guardrail/tie; movement; overload; unsafe access; unauthorised alteration.
Open sheet (page 6) - SCS-HS-CRS-03Conditional — separate approval
03 · Mobile Elevating Platforms
Boom lifts, scissor lifts and ground rescue - if hired for the job
Overturn, entrapment, ejection and electrical contact during elevated plastering or painting. Apply only after the actual machine and operator are approved.
Stop work: Failed device; unsuitable ground; unsafe overhead clearance; exceeded limits; no effective emergency lowering/responder.
Open sheet (page 7) - SCS-HS-CRS-04Conditional — separate approval
04 · Fragile Surfaces & Openings
Ceiling repairs, damaged linings and roof interfaces
Unstable ceilings, weakened structures, openings or fragile roof surfaces can cause falls or collapse. A surface finish does not prove structural strength.
Stop work: Unknown support/capacity; sagging or moving lining; unprotected opening; suspect hazardous material; unapproved roof access.
Open sheet (page 8) - SCS-HS-CRS-05
05 · Lead-Based Paint Exposure
Read with SCS-HS-LEAD-001 Rev 2.2 - 26 September 2026
Confirmed or presumed lead coatings may expose workers and residents through inhalation, ingestion and contamination carried home. Strong residual controls do not remove the critical health-risk status.
Stop work: Unknown/unresolved status; failed extraction/RPE/containment; occupant entry; escaped debris/runoff; changed method; no required monitoring decision.
Open sheet (page 9) - SCS-HS-CRS-06
06 · Asbestos & Unknown Materials
Stop, isolate and obtain competent information before disturbance
Drilling, sanding, scraping or patching older materials can release asbestos fibres. SCS current responsive-maintenance scope excludes asbestos removal and remediation.
Stop work: No adequate information for suspect material; unexpected layer/debris; damaged ACM; unverified specialist release; contamination spreading.
Open sheet (page 10) - SCS-HS-CRS-07
07 · Silica & Hazardous Dust
Preparation, sanding, mixing and clean-up of plaster/render/coatings
Respirable crystalline silica and other hazardous dust may cause serious lung disease. Confirm material composition; not all plaster dust is silica, and unknown coating dust needs separate lead/asbestos checks.
Stop work: Unknown material; no source control; failed airflow; dust escapes containment; RPE seal failure; uncontrolled slurry.
Open sheet (page 11) - SCS-HS-CRS-08
08 · Hazardous Substances
Coatings, primers, strippers, fillers, solvents and cleaning products
Toxic vapours, sensitising products, corrosive chemicals and skin absorption can cause serious illness or injury. Product selection determines the controls; no generic respirator covers every substance.
Stop work: Unknown/unlabelled product; no SDS; unsafe ventilation; incompatible mixing; exposure symptoms; occupant intrusion; uncontrolled spill.
Open sheet (page 12) - SCS-HS-CRS-09
09 · Fire & Flammable Vapours
Solvents, stripping methods, storage and ignition control
Flammable liquids/vapours and ignition sources can cause fire or explosion in occupied buildings. Hot work is excluded from the present responsive-maintenance scope.
Stop work: Vapour accumulation; ignition source cannot be controlled; blocked exit; unapproved heat/hot work; overheating or smouldering.
Open sheet (page 13) - SCS-HS-CRS-10
10 · Electricity & Live Services
Portable tools, leads, hidden services and existing property supplies
Contact with electricity or damage to concealed electrical, gas or water services can cause fatal injury. SCS does not carry out electrical, gas or plumbing work under this scope.
Stop work: Unknown service location/status; damaged lead; repeated RCD trip; wet connection; unsafe overhead approach; suspected gas/service strike.
Open sheet (page 14) - SCS-HS-CRS-11
11 · Tools, Machinery & Cuts
Mixers, sanders, blades, sharp edges and stored energy
Rotating tools, sharp edges and stored energy can cause serious cuts, lacerations, entanglement and eye injury. Routine minor cuts remain in the job JSEA; serious injury pathways need critical controls.
Stop work: Missing guard; incompatible accessory; exposed rotating parts; insecure workpiece; intervention while energised; uncontrolled cutting zone.
Open sheet (page 15) - SCS-HS-CRS-12Conditional — separate approval
12 · Pressurised Spray Equipment
Airless paint injection, hoses and stored pressure - if proposed
High-pressure spray can inject paint into tissue, rupture hoses or aerosolise hazardous products. Spray work is not assumed approved by a brush/roller JSEA.
Stop work: No spray-specific approval; damaged hose/guard; uncontrolled aerosol; failed ventilation; trapped pressure; any injection injury.
Open sheet (page 16) - SCS-HS-CRS-13
13 · Vehicles, Plant & Deliveries
Property access, reversing, loading and transport
Workers or residents may be struck by vehicles/mobile plant, or injured by unstable loads. SCS site traffic controls must match the driveway and actual delivery arrangements.
Stop work: Person in reversing zone; lost spotter; unstable/unsecured load; vehicle defect; unlicensed/impaired driver; uncontrolled plant interface.
Open sheet (page 17) - SCS-HS-CRS-14
14 · Heavy Loads & Manual Handling
Paint, compound, plasterboard, equipment and unstable materials
Heavy or awkward loads can cause serious musculoskeletal injury, crush injuries or falls. Risk depends on weight, size, repetition, reach, route and the worker, not one universal safe weight.
Stop work: Unknown/unstable load; unsuitable aid; unsafe stairs/access; people in crush zone; pain/fatigue prevents safe handling.
Open sheet (page 18) - SCS-HS-CRS-15
15 · Occupied Property & Public
Government/social housing, residents, children and vulnerable people
Residents may enter work areas or be exposed to falls, lead/dust, vapours, tools and blocked exits. Consent to enter a home does not remove the need for effective isolation.
Stop work: Isolation cannot be maintained; child/resident enters hazard zone; blocked exit; uncontrolled dust/vapour; threat; unsafe re-entry.
Open sheet (page 19) - SCS-HS-CRS-16
16 · Noise & Vibration
Powered preparation and sustained tool use
High noise and repeated vibration can cause permanent hearing loss, nerve/vascular injury or loss of safe tool control. Assess actual tools, duration and combined exposures.
Stop work: Unsafe noise exposure without controls; excessive vibration; defective tool; symptoms or loss of grip; warnings cannot be heard safely.
Open sheet (page 20) - SCS-HS-CRS-17
17 · Fatigue, Heat & Impairment
Outdoor work, travel, long days and physical workload
Fatigue, heat illness or impairment can undermine height, driving and tool controls. Weather can also defeat access and exterior containment.
Stop work: Confusion/collapse; impaired operator; fatigue prevents safe work; unsafe wind/rain; heat controls unavailable.
Open sheet (page 21) - SCS-HS-CRS-18
18 · Mental Health & Violence
Work pressure, isolated work, aggression and immediate crisis
Poor work design, bullying, threats or serious distress may cause significant harm and compromise other critical controls. This is an SCS people-risk standard; classification depends on the actual exposure.
Stop work: Immediate threat/violence; serious crisis; unsafe lone work; distress or distraction prevents safe critical tasks.
