Water skiing, rock climbing, watching a baseball game, are all examples of activities that people happily take part in, knowing that they might be injured, or incur some type of property damage. Assumption of risk is a legal theory that means, once a person has knowingly and voluntarily engaged in the risky activity, he cannot sue the host for injuries or damages incurred.
In general, people in California have a duty to use reasonable care to avoid injury to others. As the court explained: To avoid this chilling effect, owners or occupiers of premises or businesses in which a plaintiff engages in these activities have no duty to eliminate those risks.
People who play baseball at their local park assume the risk of getting hit accidentally by a pitch. It is a risk inherent in the game of baseball. George goes to his local home improvement center to rent a gas-powered high pressure washer so he can clean his patio.
Hank, who is at the counter, tells George he can't rent out the unit because it's been sparking.
George insists on renting it anyway, saying he'll be careful. Hank rents it to him. While George is using the unit, it starts a fire and George suffers burn injuries. So neither party is blameless. A jury will have to decide how to apportion responsibility for George's injury.
When does the doctrine not apply? Assumption of the risk does not bar recovery in cases in which the defendant violated the law or unreasonably increased the risks to the plaintiff over and above those inherent in the activity.
Bob is pitching at a friendly baseball game at the local park. The game is tied in the bottom of the 9th with two outs when Carl, a power hitter, comes to the plate. Bob throws a fastball at Carl's head to get him out of the game. While accidentally getting hit by a pitch is an inherent risk of playing baseball, people who play a friendly game do not expect the pitcher to intentionally throw a fastball at their head.
Carl has not assumed the risk of an intentional injury. What if the plaintiff signed a liability waiver?
Sometimes a person or company providing a risky service or product will ask a participant to sign a written contract. But a defendant cannot legally require someone to waive the right to sue for gross negligence, recklessness or intentional torts.

Assumption of risk can either be express or implied. An express assumption of risk is often made in writing, usually in the form of a signed waiver or contract. However, an express assumption of risk doesn't have to be in writing, it can also be made verbally.
"Primary assumption of the risk" -- in which the risk of injury is such an inherent part of an activity that the defendant has no liability for ordinary negligence, and "Secondary assumption of the risk" -- in which the defendant still owes a duty of care to the plaintiff.5/5. “Assumption of Risk” is a legal theory that basically means a person knew a situation could be dangerous but voluntarily entered the situation anyway, knowing the risks.
For instance, when you go to a baseball game, you know there is a risk of being hit by a foul ball. Also, assumption of risk does not absolve a defendant of liability for reckless conduct.  This defense is commonly asserted in cases of injuries occurring during risky recreational activities, such as skiing, paragliding, and scuba diving, but actually extends to all dangerous activities.
