Screeding & Topping SWMS
NSW — Screeding & Topping.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Screeding and topping is the placement and finishing of cementitious screeds, self-levelling underlayments and industrial toppings. It is high risk construction work under the WHS Regulation because it can be carried out more than 2 m above the ground on suspended slabs and mezzanines, it can create a contaminated or flammable atmosphere where solvent primers and resins are used indoors, and it involves the movement of powered mobile plant such as screed pumps and mixers (s291), so a SWMS is mandatory (s299). The dominant hazard is cement contact: fresh screed, self-levelling underlayment and topping are strongly alkaline (pH 12-13) and cause chemical burns that are often painless at first, with kneeling in wet material causing serious knee and lower-leg burns — a classic and underestimated injury in this trade. Equally dominant are the hazardous manual tasks: sustained awkward-posture screeding and repetitive trowelling and floating drive back, shoulder and knee injury. Around them sit respirable crystalline silica from dry-shake toppings and from grinding set screed, screed-pump line burst and mixer entanglement, the contaminated/flammable atmosphere from solvent primers, and falls from suspended slab edges and mezzanines. The SWMS controls cement-contact PPE, manual-task design, silica and atmosphere control, plant safety and fall protection. It supports the manufacturer's system and does not replace it. It is supplied in eight jurisdiction editions, each citing its own Act, Regulation and regulator.
Hazards identified
8 hazards covered, sorted by priority.
Deep alkaline burns, especially to knees and lower legs from kneeling in wet material (dominant hazard)
Back, shoulder and knee musculoskeletal injury (dominant hazard)
Fire, explosion or toxic exposure in a poorly ventilated area
Fall fatality or serious injury (WHS Reg Part 4.4)
High-pressure release and impact injury
Silicosis; exposure exceeding the 0.05 mg/m3 WES
Entanglement or crush injury at the mixer
Corneal chemical burn
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Use a pump-applied self-levelling system placed and finished without prolonged kneeling, or a factory-finished panel, where the design allows
- 2Substitution — Substitute water-based primers for solvent-based systems to remove the flammable-atmosphere risk, and low-silica pre-blended toppings for dry-shake broadcasting
- 3Engineering — Screed pump maintained with secure couplings and a safe blockage-clearance procedure, and mixer guarding maintained
- 4Engineering — Forced ventilation and atmospheric monitoring when using solvent primers indoors, with ignition sources excluded
- 5Engineering — Edge protection at suspended slab edges and mezzanines, and on-tool extraction for any grinding of set screed
- 6Administrative — Manual-task design — long-handled tools, task rotation, knee protection and rest breaks — to control the sustained-posture injury
- 7Administrative — SDS-based handling of primers, resins and cementitious products, and silica exposure control where dry-shake or grinding occurs
- 8Administrative — Fall-protection plan for above-2 m work and a plant traffic-management approach for pumps and mixers
- 9PPE — Alkali-resistant gloves and waterproof knee protection to prevent cement burns, plus eye protection
- 10PPE — Fit-tested P2 respiratory protection for dry-shake/grinding, Type 1 hard hat and fall-arrest where required

Worked example
At 7:00 am a crew from Levelset Flooring places a cementitious topping across a suspended first-floor slab. The supervisor treats cement burns as the defining risk: the crew are in alkali-resistant gloves and waterproof kneepads, and a new starter is reminded that a screed burn from kneeling in wet material often is not felt until it is serious. The work is designed to reduce sustained kneeling — long-handled screeds and floats are used, tasks are rotated and breaks scheduled to protect backs, shoulders and knees. Because the slab edge is above 2 m, edge protection is up before anyone screeds near it. A solvent-free primer is used, but where a resin section needs ventilation the area is force-ventilated, monitored and kept clear of ignition sources. The screed pump runs with secure couplings and a set blockage-clearance procedure so no one clears a blocked line under pressure. A dry-shake stage is done with a low-silica blend and P2 respirators. The topping is placed and finished to the manufacturer's system with the crew's exposure and postures managed throughout.
