Winchester WHS Consultants helps WA businesses manage high-risk work with practical WHS systems, silica risk controls, fit testing, SWMS reviews, audits and incident investigations — specialising in construction, civil, demolition and resources across Western Australia.
Respirable crystalline silica (RCS) is generated when cutting, grinding, drilling, or crushing materials like stone, sand, concrete, and brick. Exposure to RCS can cause serious and irreversible lung disease, including silicosis and lung cancer. The risk increases where dust is uncontrolled, airborne and inhaled by workers.
Businesses processing crystalline silica substances must assess whether the work is high risk. Where high-risk CSS processing is identified, a Silica Risk Control Plan — or a compliant SWMS for high-risk construction work — must be prepared and made available to workers before the work starts.
Rob Winchester brings hands-on industry experience to every silica engagement — supporting risk assessments, silica risk control planning, worker training, and coordination of air monitoring and health surveillance where required.

Rob Winchester provides practical incident investigation support focused on understanding what really happened, why it happened, and what needs to change.
Rob is ICAM-trained and applies the four key work lenses to help organisations investigate incidents properly and improve controls in a meaningful, lasting way — not just tick a box. Discover our full independent ICAM incident investigation services across Western Australia.
How the task was assumed or expected to be done by designers, engineers, managers, or planners. This lens reveals the assumptions baked into systems that workers never had a say in.
How the work is documented in procedures, SOPs, SWMS, manuals, and permits. This lens shows whether documentation reflects reality — or just good intentions on paper.
How the work is typically carried out in real operational conditions day to day. This captures the informal adaptations workers develop to get things done safely and efficiently.
How the work was actually performed at the time of the incident. This is the ground truth — what happened in the real world, under real conditions, with real pressures and constraints.
Ensure the incident scene is preserved and key evidence — physical, documentary, and digital — is captured before it's lost.
Structured interviews using cognitive interviewing techniques, reviewed alongside CCTV, records, and physical evidence.
Map WAI, WAW, WAND, and WAD to build a complete picture of the conditions that led to the event.
Trace causal chains through task, individual, team, workplace, and organisational factors using the ICAM framework.
Recommendations that target root causes — not surface-level fixes — with clear ownership and measurable outcomes.
"Most incidents don't happen because someone did something wrong. They happen because the gap between how work was designed and how it actually gets done was never understood."
