Final answer:
In strict products liability cases involving injuries caused by the latent effects of exposure to a toxic substance, the accrual of a cause of action is computed from the time when the injury or harm becomes evident or is discovered.
Step-by-step explanation:
In strict products liability cases involving injuries caused by the latent effects of exposure to a toxic substance, the accrual of a cause of action is computed from the time when the injury or harm becomes evident or is discovered, rather than from the time of exposure to the substance.
For example, if a person was exposed to a toxic substance 10 years ago but only recently discovered that they have developed health problems as a result of that exposure, the accrual of their cause of action would be calculated from the time of discovery.
This approach is followed because latent injuries caused by toxic substances may not manifest immediately and it may take years for the effects to become apparent.
