Hydraulic fluid is indeed an irritant. Prolonged exposure causes a form of dermatitis, acne, and a whole bunch of other skin conditions cancer among them. I've got a barrel of the stuff on the shelf, industrial grade. It won't bother you that day unless you are hypersensitive, but long term exposure or repeated exposure in a short period will cause problems and need medicla attention. Just try not to get it on you, and if you do wash it off again as soon as you can. Aviation grade would have different additives that would make it even less friendly than Industrial grade, and all forms of hydraulic oil become powerful acids if they get moisture contamination and are not replaced in a timely manner. I've seen systems dissolve vital components because of that, and do not want that gross stinky acid-oil getting on me.
Oxygen generators are really fun. I want to play with some of those- outdoors and far removed from any structures. The best I get to play with is bottled compressed oxygen, and a few of the milder oxidizers that I can buy at the hardware store. Most anything becomes explosive when in the presence of pure oxygen or even oxygen-enriched air, even things that you don't expect to burn like copper and stainless steel piping. Oh and with aircraft making extensive use of the already somewhat reactive aluminum and magnesium, having a high oxygen concentration and an ignition source is a recipe for a really hot time.
Paint is nasty. Doesn't matter what business you are in, paint will always be a nasty chemicals situation. 2 and 3 part urethane paints are not to be taken lightly, they'll put you in the hospital from fume inhalation if you don't have the proper type of respirator. And many formulations are so potent that they require an air-supplied respirator or SCBA, the traditional cartridge type is not good enough to deal with their chemistry. I'm constantly dealing with safety violations on the paint booth where I work because some of the older guys insist that their cartridge respirators are fine even though the Safety Data Sheet for the paint they are using clearly states that a supplied air type is required.
Cleaning chemicals are pretty standard. Solvents are flammable into explosive, keep Chlorine and Ammonia far apart, be careful mixing acidic products with water etc.
They probably should have also covered Lock Out / Tag Out procedures to isolate and de-energize equipment before working on it. This is important, and will be used regularly. It is the #1 thing in keeping all your fingers and toes attached while performing maintenance or cleaning operations when working in industry, and I have little doubt that aircraft would have an even more sophisticated version to deal with the complexity of aircraft systems.
And of course fire shock and explosions. Turbines are scary fun, because if anything goes wrong its usually in a million pieces. Now I have seen videos demonstrating modern jet engines having their cowlings tested such that a bladeoff event does not send fragments of the turbofan through the wing of the aircraft, but there is no such protection around the high pressure turbine. If it comes apart, it is coming apart all over everyone and everything nearby. They test engines in risky situations using outdoor or hardened test cells precisely for that reason, but they do sometimes pop when spooled on the taxiway or outside the hangar.
