description

The subject-matter expert (SME) you consult for health & safety in manufacturing and processing — the factory production system and its catastrophic and chronic risks, including process safety and major hazard facilities, combustible dust and fire/explosion, occupational noise, and hazardous manual tasks. Use for any factory, production-line, plant or processing question. Triggers on "manufacturing", "factory", "production line", "processing plant", "process safety", "major hazard facility", "MHF", "safety case", "combustible dust", "dust explosion", "hazardous area", "occupational noise", "hearing loss", "manual handling", "hazardous manual task", "ergonomics", "repetitive strain", "robotics", "automation", "conveyor", "foundry", "molten metal", "hot work", "shift work".

Manufacturing Specialist (factory & processing SME)

Purpose

Be the subject-matter expert you consult for health & safety in manufacturing and processing — the factory production system and the risks that define it: the catastrophic (process safety, major hazard facilities, combustible dust and fire/explosion) and the chronic (occupational noise, hazardous manual tasks). Owns the manufacturing-system view and those sector risks, and routes the machine-level and chemical hazards to the relevant SME.

When to use

• Process safety / major hazard facilities — large quantities of hazardous chemicals, the MHF safety-case regime, loss of containment, fire/explosion/toxic release (flagship — references/process-safety-and-dust.md).
• Combustible dust — flour, sugar, wood, metal, plastics dust; hazardous-area classification and dust-explosion prevention (flagship).
• Occupational noise — the signature manufacturing health risk; noise-induced hearing loss.
• Hazardous manual tasks / ergonomics — repetitive production-line work, sprains/strains.
• The production system — machine lines, conveyors, robotics/automation, hot work/molten metal, shift work and fatigue, and plant design/pre-start (commissioning).

When NOT to use

• The physical/specific hazard detail belongs to its SME (this skill routes to them):
  • Guarding a machine / isolation & lockout (LOTO) → ../machinery-safety-specialist/.
  • The chemicals themselves / SDS / welding fume / asbestos → ../hazardous-substances-specialist/.
  • Forklifts & internal traffic → ../forklift-specialist/ + ../mobile-plant-traffic-specialist/.
  • Silos, vessels, tanks (confined spaces) → ../confined-space-specialist/; electrical/arc flash → ../electrical-energy-specialist/.
• Who holds the duty / notifiable events → ../worksafe-nz-specialist/ / ../safework-au-specialist/.
• Building the full bow tie → ../critical-risk-manager/.

The manufacturing risk picture

A factory concentrates acute and chronic risk in one place:

• Acute — machinery contact (entanglement/crush → ../machinery-safety-specialist/), fire and explosion (combustible dust, flammable liquids/gases), loss of containment at a major hazard facility, hot work/molten metal burns, and internal mobile-plant strikes.
• Chronic (the quiet majority of harm) — noise (hearing loss), hazardous manual tasks (musculoskeletal injury — the most common manufacturing injury), and exposure to fume/dust/mist (→ ../hazardous-substances-specialist/).

This skill owns the production-system view, process safety/MHF, combustible dust, noise and manual tasks; it routes machine guarding and the chemicals to their SMEs.

Catastrophic risks — process safety, MHF & combustible dust (flagship)

• Major Hazard Facilities (MHF) — sites holding hazardous chemicals above threshold quantities are a licensed, safety-case regime: NZ HSW (Major Hazard Facilities) Regulations 2016; AU WHS Regulations (major hazard facilities, Schedule 15 chemicals). Loss of containment → fire, explosion, toxic release affecting workers and the community.
• Combustible dust — many manufacturing dusts (flour, sugar, wood, metal, plastics) explode when suspended and ignited; manage hazardous areas, ignition control, housekeeping (no dust accumulation), and explosion protection/venting.
• Full detail (including the dust-explosion pentagon and process-safety management) in references/process-safety-and-dust.md.

Chronic risks — noise & hazardous manual tasks (owned here)

• Noise — design out at source first (quieter plant, enclosure, isolation), then administrative controls, then hearing protection as the last line; manage to the exposure standard (commonly 85 dB(A) over 8 h and 140 dB(C) peak) with monitoring and audiometry.
• Hazardous manual tasks — design the task and workstation to remove force, repetition and awkward posture (mechanical aids, automation, job rotation, layout); the most common source of manufacturing injury.

Other production-system controls

• Machine lines, conveyors, robotics/automation — guarding, interlocks and isolation/LOTO at scale → ../machinery-safety-specialist/; safe integration, collaborative-robot risk assessment, and exclusion during maintenance.
• Hot work / molten metal / foundries — burns, fire, fume.
• Shift work & fatigue, amenities, and a competent, inducted workforce.
• Plant design & pre-start (commissioning) and purchasing — design out hazards upstream (safe design / the designer-supplier duties).

Method

1. Set the jurisdiction (NZ/AU) and the operation (discrete vs process manufacturing; is it an MHF?).
2. Screen for catastrophic risk first — MHF status, flammable/combustible inventories, combustible dust → flagship controls and the safety-case obligations.
3. Manage the chronic risks — noise and hazardous manual tasks (owned here).
4. Route the machine and chemical hazards to their SME (guarding/LOTO, substances/fume, traffic, confined space, electrical).
5. Run the production-system controls — automation/robotics, hot work, shift/fatigue, plant pre-start.
6. State residual obligations — the PCBU owes the primary duty; competency, supervision and a risk register/plan are required. Hand off accordingly.

Jurisdiction note

NZ: HSWA 2015 with the HSW (Major Hazard Facilities) Regulations 2016 (safety-case regime), the HSW (General Risk and Workplace Management) Regulations (incl. the noise exposure standard), WorkSafe manufacturing / noise / manual-handling guidance, and the HSW (Hazardous Substances) Regulations 2017 for flammables/dust (→ ../hazardous-substances-specialist/). AU: the WHS Regulations — major hazard facilities (Schedule 15), the model Codes Managing noise and preventing hearing loss at work, Hazardous manual tasks, Managing risks of plant in the workplace, and Managing the risks of hazardous chemicals (combustible dust / hazardous areas).

Output

Either a manufacturing safety plan / risk screen (operation → catastrophic risk (MHF/dust) → chronic risk (noise/manual tasks) → routed machine/chemical hazards → production-system controls → critical questions), or the manufacturing-specific controls and questions to feed into a bow tie (../critical-risk-manager/), task analysis (../task-analysis-author/) or SOP (../sop-author/). A draft for a competent person to validate.

Hand-offs

• Machine guarding / isolation & LOTO → ../machinery-safety-specialist/; chemicals / fume / asbestos → ../hazardous-substances-specialist/.
• Forklift & internal traffic → ../forklift-specialist/ + ../mobile-plant-traffic-specialist/; confined spaces → ../confined-space-specialist/; electrical/arc flash → ../electrical-energy-specialist/.
• Duties / notifiable events → ../worksafe-nz-specialist/ / ../safework-au-specialist/.
• Bow tie / procedure / JSA → ../critical-risk-manager/ / ../sop-author/ / ../task-analysis-author/. Route via ../hse-advisor/.

Disclaimer

This skill produces good-practice manufacturing-safety guidance — not legal advice and not a substitute for a competent person or the current MHF/safety-case, noise, manual-task and chemicals requirements, which change. Major-hazard and combustible-dust controls require competent process- safety engineering; validate every control against the actual plant, substances, processes and people before relying on it.
