Third-Party-Over and the Three Employers Liability Limits
Ironwood Fabrication operates a machine shop and buys a standard workers compensation and employers liability policy from a private carrier. Part One is written with no dollar limit, as required by statute. Part Two limits are $1,000,000 each accident, $1,000,000 disease each employee, and $1,000,000 disease policy limit. In March 2024 a pressure vessel failed and three Ironwood employees were injured. All three sued Cascade Valve, the manufacturer, and Cascade in turn filed a third-party complaint against Ironwood for contribution, alleging Ironwood's negligent maintenance contributed to the injuries; Cascade's complaint seeks $2.4 million and includes a demand for punitive damages. Separately, in 2025 two long-service employees filed hearing-loss claims alleging occupational disease from years of cumulative noise exposure, seeking $600,000 each. Ironwood's plant manager wants to know what the policy pays.
1. Which part of the policy responds to Cascade's contribution complaint, and what does Part One pay toward it?
Read the worked answer
Part One pays nothing toward it. Part One is workers compensation coverage: it pays the statutory benefits owed to injured employees and, by doing so, secures the employer the exclusive remedy protection of the workers compensation statute. It does not pay damages awarded against the employer in a civil suit, and it does not fund a contribution claim by a third party.
Part Two responds. Employers liability covers sums the insured is legally obligated to pay as damages because of bodily injury to its own employees, and a third-party-over action - where an injured worker sues an outside party that then seeks contribution or indemnity from the employer - is the classic trigger. The carrier also has the right and duty to defend Ironwood in that action.
Two exclusions to check. Part Two excludes liability assumed under contract, so any indemnity obligation Ironwood signed away in a maintenance contract is outside coverage. Part Two also excludes punitive or exemplary damages, and many states will not permit insurance for them in any event, so the punitive demand is outside regardless.
Bottom line: Part Two defends and indemnifies within limits, minus the punitive exposure.
2. Cascade seeks $2.4 million, driven mainly by one catastrophically injured employee. Apply the limits correctly.

Each accident is the outer cap. The $1,000,000 each accident limit is the most payable for all damages because of bodily injury to employees in any one accident, regardless of how many employees are injured, how many claims are filed, or how many claimants join. One pressure-vessel failure equals one accident, so the whole March 2024 event is capped at $1,000,000 - not $1,000,000 per employee.
Each employee is a sub-cap, not an addition. If Cascade's demand were allocated almost entirely to the most seriously injured worker, that individual's share is still capped at $1,000,000. The each employee limit constrains what any one employee can collect; it does not sit on top of the each accident limit.
Arithmetic. Claimed $2,400,000, capped at $1,000,000. Any punitive award is excluded and would not erode the limit further, but it also creates an uninsured exposure.
Why the structure exists. The three Part Two limits are separate: an each accident limit for injury events, a disease each employee limit, and a disease policy limit for all disease claims combined. Mixing them up - for example, paying $1,000,000 per injured employee - is a common and expensive error.
3. How do the two 2025 hearing-loss claims interact with the March 2024 payments?
Read the worked answer
Different limit, different bucket. Cumulative hearing loss from prolonged noise exposure is an occupational disease, not an accidental injury. It is not paid from the each accident limit that was eroded in March 2024, so the earlier payment does not reduce the disease capacity.
Apply both disease limits. Each employee has $1,000,000 of disease coverage, and both $600,000 claims sit within that per-employee cap. But the disease policy limit of $1,000,000 is the total payable for all occupational disease claims during the policy period, regardless of the number of employees. Two claims totaling $1,200,000 therefore pay $1,000,000 combined.
Timing question. Coverage depends on when the disease is deemed to have been contracted or last injuriously exposed under the applicable statute, not simply when the claim was filed. Exposure spanning 2015 to 2024 may implicate several policy periods, and the carrier should apply the state's last-injurious-exposure rule to decide which policy year's limits respond.
Bottom line: full accident limit still intact for future injury events; disease capacity effectively exhausted by the two hearing-loss claims.
