Limitation — distinguishing PI (s.11) from contract (s.5)

A supplier delivers machinery to a manufacturer under a simple contract, not a deed. On 3 March 2024, its defective machinery causes a fire that seriously burns an adult factory worker and damages the factory. That day the worker knows the burns are serious, that they resulted from the supplier's defective machinery and who the supplier is. He proposes a negligence claim against the supplier for his injuries. The manufacturer proposes a contract claim against the supplier for the factory damage; the contractual breach also occurred on 3 March 2024. Neither claimant is under a disability, and there is no later date of knowledge or concealed fact to consider. Which best states the applicable primary limitation periods, leaving aside any discretionary extension?
