PUBLIC LIABILITY INSURANCE THAT PROTECTS YOUR FACILITY, VISITORS & CONTRACTS

Why Public & Third-Party Liability Matters in Semiconductor Manufacturing

Semiconductor manufacturing is a high-control environment with complex hazards: cleanrooms, high-voltage systems, chemical handling, compressed gases, automated tools, raised floors, maintenance works, delivery movements, and constant third-party presence from equipment vendors and specialist contractors. Even if your own internal controls are strong, a single incident involving a visitor, supplier, adjacent unit or contractor can turn into a substantial liability claim.

Public liability (also known as third-party liability) is designed to protect your business if a third party alleges injury or property damage arising from your premises or operations. For semiconductor companies, that can include incidents on-site, during installation/commissioning works, at customer premises, or linked to off-site activities such as field service, testing or training.

Insure24 arranges tailored public & third-party liability insurance programmes for wafer fabs, foundries, IDM operations, semiconductor R&D, packaging and test houses, and the broader supply chain (materials, gases, metrology, equipment maintenance, and specialist engineering support).

What Does Public & Third-Party Liability Insurance Cover?

Public liability insurance typically covers your legal liability to pay compensation (and associated legal defence costs) if a third party suffers bodily injury or property damage and alleges it was caused by your negligence. Policies are not all the same — wordings, conditions and exclusions matter — especially in semiconductor environments where contamination, chemicals, high-value customer property, and contract obligations can complicate claims.


  • Third-party bodily injury: injury to visitors, contractors, customers or members of the public
  • Third-party property damage: damage to property belonging to others (including adjacent units, landlord assets, or customer property brought on-site)
  • Legal defence costs: solicitor fees, expert witnesses and investigation costs (subject to policy terms)
  • Products and completed operations options: cover can extend to liability arising from products supplied or works completed (often arranged alongside products liability)
  • Off-site activities: site visits, field service, installation support, audits, and demonstrations where required
  • Contractual requirements: limits and wordings aligned to landlord, customer and principal contractor demands
  • Pollution extensions (where available): sudden and accidental pollution events may be addressed by extensions or separate environmental liability
  • Worldwide cover (where required): useful for businesses with international customers and site activities (subject to underwriting)

Common Liability Claim Scenarios in Semiconductor Facilities

Liability claims often arise from simple operational events — slips, trips, equipment movement, chemical handling, contractor works — but the semiconductor context can amplify the cost due to sensitive environments, strict access protocols and high-value property. Here are realistic scenarios that public and third-party liability insurance is designed to respond to (subject to policy terms and exclusions).

1) Visitor or contractor injury on-site


A contractor slips on a wet floor during maintenance of a chiller plant, or a visitor trips on a raised-floor edge near a tool bay. Claims can involve medical costs, loss of earnings, rehabilitation and legal fees. Where contractors work at height or around electrical systems, incident severity can increase quickly.

  • Slips/trips/falls in production and plant areas
  • Injury during tool moves, rigging and lifting operations
  • Exposure incidents linked to chemicals or gases
  • Accidents during deliveries and yard movements

2) Damage to third-party property


Property damage can happen when contractors impact a landlord’s building services, flood adjacent occupiers, or cause damage to a customer’s equipment brought on-site. Semiconductor sites often have shared utilities and complex infrastructure, increasing the risk of knock-on property damage claims.

  • Water leaks damaging neighbouring units or landlord plant
  • Forklift or vehicle collision with third-party property
  • Accidental damage during installation/commissioning works
  • Damage to customer-owned tooling, racks or measurement devices

3) Chemical handling incidents affecting third parties


Semiconductor operations often use acids, solvents and specialty chemicals. A spill, vapour release or incorrect storage can result in allegations of injury or property damage to third parties. Some pollution events require specialist environmental cover; however, public liability may respond to certain third-party claims depending on the circumstances and the wording.

  • Chemical spill in shared areas impacting contractors
  • Accidental release during transfer or bund failure
  • Damage to third-party equipment due to corrosive exposure
  • Legal defence costs while liability is investigated

4) Off-site liability during field service & support


Many semiconductor businesses send engineers to customer premises for installation support, calibration, training or troubleshooting. If an engineer damages a customer’s property or a third party is injured during your work, liability claims can follow.

  • Accidental damage to customer equipment during service work
  • Injury to customer staff during demonstrations or tests
  • Tooling, rigging and access risks on unfamiliar sites
  • Contractual liability clauses in service agreements

Why Liability Wordings Matter for Semiconductor Risks

Many businesses buy “public liability” and assume they are protected. In reality, the outcome of a claim often depends on definitions and exclusions: what counts as “property”, whether “work away” is included, how contractors are treated, whether heat work or hazardous substances have conditions, and what the policy says about gradual pollution, contamination, or professional services.

Key areas we review when arranging your policy

Insure24’s approach is to align your liability cover to your operational reality and your contract obligations — not just the cheapest premium. We’ll also help you avoid the most common pitfalls that create claim disputes.

Premises & operations


  • Visitor controls, access restrictions and contractor management
  • Use of forklifts, lifting gear, rigging contractors and heavy equipment moves
  • Hot works and permit-to-work systems (if applicable)
  • Shared premises and landlord interface (service corridors, plant rooms, roof access)
  • Events, training sessions and customer visits on-site

Contractual risk


  • Minimum liability limits required by customers and landlords
  • Indemnity clauses, hold harmless wording and “assumed liability” concerns
  • Principal’s indemnity requirements and contractor/agency labour
  • Overseas contract requirements (territorial limits and jurisdiction)
  • Certificates of insurance and evidence of cover on short notice

Hazardous materials & pollution


  • Chemical storage and transfer processes
  • How your policy addresses “sudden and accidental” events
  • Where separate environmental liability may be required
  • Waste disposal and third-party transport arrangements
  • Emergency response, incident reporting and documentation standards

Products vs public liability


  • Where products liability is necessary (chips/components supplied to others)
  • Completed operations cover where you install or modify equipment
  • Customer property in your care, custody or control (CCC)
  • Recall exposures and the role of specialist recall cover
  • High-reliability end uses (automotive, aerospace, medical, industrial safety)

Liability programmes for semiconductor operations often work best when public liability is arranged alongside employers’ liability, product liability, professional indemnity (for testing/design), cyber/OT, and environmental cover. We’ll help you build a coherent programme so there are fewer gaps between policies.

Choosing the Right Liability Limit

Public liability limits are typically selected based on contract requirements, footfall/visitor exposure, the nature of work performed, and worst-case property damage scenarios. Semiconductor facilities are often in industrial parks or shared sites where a single event can cause damage beyond your own premises.

Common contract requirements for public liability limits include £2m, £5m, £10m or more. If you host frequent customer visits, operate large facilities, conduct tool moves, or handle hazardous substances, higher limits may be appropriate. If your customers are global or your products feed into critical applications, they may require higher limits or specific wording endorsements.

Practical factors that influence pricing

  • Number of visitors and contractors on-site and how access is controlled
  • Presence of lifting operations, fork-lifts, rigging, cranes and heavy tool movement
  • Chemical and gas handling controls (bunding, detection, training, emergency procedures)
  • Claims history and incident reporting culture
  • Quality and maintenance discipline (especially where incidents could affect third parties)
  • Overseas activities, exports and territorial limits
  • Whether you require “principal’s indemnity” or additional insured endorsements

If you’re unsure, we’ll help you map your realistic worst-case scenarios and align your limits with both contracts and practical exposure. That avoids overpaying for unnecessary limit while ensuring you’re not underinsured for a major claim.

Risk Management Tips That Support Better Liability Terms

Liability insurance is strongest when it sits alongside strong controls. Underwriters often price based on evidence of contractor management, incident reporting discipline, and how you control access in high-hazard areas. These practical steps can reduce incidents and can help support more favourable insurance terms.


  • Visitor and contractor induction with documented sign-in, escorts and restricted zones
  • Permit-to-work for high-risk activities (hot works, electrical, confined spaces, roof access)
  • Clear housekeeping standards to reduce slip/trip hazards around raised floors and plant rooms
  • Lifting plans for tool moves and clear separation of pedestrian/vehicle routes
  • Chemical and gas handling SOPs, bunding and spill response drills
  • Incident reporting and near-miss logging to evidence learning and control improvements
  • Regular review of contracts so liability is not unintentionally assumed beyond insurable terms

FREQUENTLY ASKED QUESTIONS

+-

What is public liability insurance for a semiconductor manufacturer?

Public liability insurance (third-party liability) protects your business if a third party alleges injury or property damage arising from your premises or operations. For semiconductor companies this can include incidents involving visitors, contractors, deliveries, facilities works, or off-site activities such as field service and installation support (subject to policy terms and exclusions).

+-

What limit of indemnity do semiconductor businesses typically need?

Many contracts request £2m, £5m or £10m public liability, though larger facilities or businesses with higher visitor volumes, chemical exposures, extensive contractor works or overseas activities may need higher limits. The right limit depends on your contracts, site profile and worst-case property damage exposure.

+-

Does public liability cover damage to customer property brought to our site?

It may, but “care, custody or control” (CCC) conditions can restrict cover when third-party property is under your control. If you regularly handle customer-owned equipment, tooling or devices, we’ll review the wording and, where needed, recommend appropriate extensions or separate covers to reduce gaps.

+-

Is public liability the same as product liability?

No. Public liability focuses on incidents arising from your premises or operations (e.g., a visitor injury at your site). Product liability relates to injury or damage caused by products you manufacture or supply (e.g., defective components). Many semiconductor businesses need both, especially if supplying chips, assemblies or modules to third parties.

+-

Does public liability cover chemical spills or pollution?

Some policies can respond to certain sudden and accidental events, but pollution is often restricted and may require specific endorsements or a dedicated environmental liability policy. Because semiconductor operations can involve chemicals and gases, we’ll review your processes and recommend the right structure for insurable pollution exposures.

+-

How quickly can Insure24 arrange cover?

For straightforward risks we can often provide indicative terms quickly. Where the site is complex (chemicals, high contractor volume, overseas activities, higher limits), allow 1–2 working days to present the risk to specialist markets and confirm the best wording and pricing.
