Facts

Hood bought a Ryobi miter saw that came fully assembled with upper and lower blade guards and multiple warnings on both the saw and in the manual stating not to operate the saw without the guards in place. After finding that the guards prevented him from cutting a four-inch piece of wood completely through, Hood removed the guards by taking off the blade, unscrewing the guard assembly, and reinstalling the blade on the bare spindle. He continued using the saw without replacing the guards, and about twenty minutes later the spinning blade flew off, partially amputating his thumb and lacerating his leg. Hood admitted reading the manual and most warning labels but argued the warnings should have specifically said that removing the guards could cause blade detachment.

Issue

Were Ryobi's warnings legally inadequate because they did not specifically warn that removing the blade guards could cause the blade to detach, and was the saw defectively designed despite Hood's removal of the guards in violation of clear warnings?

Rule

Under Maryland law, a warning need only be reasonable under the circumstances; a manufacturer need not provide an encyclopedic warning or warn of every mishap that might result from misuse. A manufacturer must design a product to be safe for reasonably foreseeable uses, but a consumer's post-sale alteration that directly causes the injury defeats a design defect claim, and the manufacturer need not foresee that users will disregard clear, simple, and unmistakable safety warnings.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Columbus, Ohio, Elena Morris bought a benchtop grinder from Lakeview Tool Works. The grinder and manual each stated several times, in large print, 'Never use without eye shield attached' and 'Serious injury may result,' but did not state that removing the shield could allow metal fragments to ricochet toward the operator's face; Elena removed the shield and was injured by a fragment.

If Elena sues claiming the warnings were inadequate because they failed to describe the precise mechanism of injury, how should the court likely rule?

Explanation. The majority rule is that a manufacturer need provide only a reasonable warning under the circumstances, not an encyclopedic one. Clear, repeated instructions not to use the product without a safety feature, coupled with a warning of serious injury, are adequate even if they do not specify the exact mechanical consequence of misuse.
