A compound fracture is an open fracture where the broken bone communicates with the outside through a skin wound, meaning the bone may protrude or be exposed. This distinguishes it from a closed fracture, where the skin remains intact. The defining feature is the skin breach with the bone involved, which raises infection risk and requires prompt, careful management: cover the wound with a sterile dressing if possible, immobilize the limb, and seek urgent medical care (tetanus and antibiotics are considerations). The other scenarios don’t fit: a fracture of the radius alone isn’t necessarily open; a fracture from repetitive use describes a stress fracture; and a fracture with bone splintered into many pieces describes a comminuted fracture, which is about fragment count rather than skin opening.

In death cases, the DIA form 510 is the notice used to identify dependents for survivor benefits and to prompt the Division of Industrial Accidents to determine who may be entitled to benefits. The form must be filed unless the employer actually knows that the employee left a totally dependent spouse. That specific knowledge is the key exception: if there is a spouse who is entirely dependent on the decedent for support, the dependency status is already established, so there’s no need for the employer to submit the form to confirm dependents. When there isn’t such clear knowledge of a totally dependent spouse, the form is needed to uncover whether other dependents exist (like minor children or partially dependent spouses) and to help apply the proper priorities for survivor benefits. The other potential dependents described in the options would require gathering information to determine eligibility, so the form would typically be filed in those circumstances.

The essential point is the deadline for the private annual report. Private self-insurance plans must submit this yearly financial report to the state by March 1, covering the previous calendar year. The March 1 date aligns with a standard reporting cycle: the year ends on December 31, and March 1 gives regulators a consistent, timely window to review year-end financial data and ensure solvency and regulatory compliance. Other dates don’t fit this annual cycle, so they aren’t correct.

Aggregate excess insurance describes coverage that kicks in once the total losses for the policy period have reached a specified cumulative (aggregate) limit. It protects against further losses beyond that threshold, up to the excess policy’s own limit. This is different from specific excess coverage, which responds only when a single claim exceeds a per-claim amount. Primary insurance is the initial layer of coverage, and reinsurance is insurance purchased by insurers themselves. So after the cumulative losses hit the set aggregate limit, the aggregate excess policy provides protection for losses beyond that point up to its limit.

Temporary total disability benefits in California are calculated as two-thirds of the employee’s average weekly wage, but there is a yearly maximum cap. For 2010, the statutory ceiling is $986.69 per week, so the maximum TTD rate you can receive in that year is $986.69, regardless of what two-thirds of the AWW might otherwise amount to. The other options do not reflect the 2010 cap and therefore are not the maximum rate for that year.
