工伤

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.

伤 = 亻 + 𠂉 + 力 : Sherlock Holmes hurt himself when he got struck by one of the traps in front of the anglepod. Luckily Rosa Luxemburg passes by: she has the key to unlock the power button of the trap system and turns it off, so that Sherlock can free himself.
