Glorious Science!

The Federation clearly thinks something like OSHA isn't important.
The Empire from Star Wars at least has the excuse that they're outright evil. So the lack of safety railing in the Death Star tracks.
The Federation is supposed to be filled with the brightest, best, and most empathetic but their safety procedures are basically nonexistent.
- Further evidence:
  Nevermind the lack of environmental suits.
  
  Just rawdogging that new planet.
  
  Remember the episode where Trip gets pregnant, and he gets all broody and he rides the man lift in engineering up to demonstrate that the things which are at perfect hand rail height, that you'd probably like to hold onto while riding a lift in a large vehicle that might move suddenly, shears right past a support in its hoist way so if you did actually hold it like a hand rail you'd cut your fingers off?
  Starfleet be negligent.
  
  The questions Enterprise never answered for me: When they're between planets and Porthos has to poop, does he just poop on the floor of the ship? Are there little puddles of Porthos pee that crewpeople slip on? Is there a crewman whose job is dog cleanup duty?
- How else would anything interesting happen in the episode? In my head canon most of the federation is very responsible but also boring. That's why the show follows this particular bunch of degenerates.
  
  That's basically the premise of Lower Decks lol
  
  I considered that, too.
  Enterprise is an exploration and research vessel so maybe their whole thing is they're doing experiments on a shoestring out in the middle of nowhere.
  
  Remember they aren't they aren't getting paid, they are there because they are the biggest risk addicts in the federation.
- Tucker in ENT S1E5 was right... those ships ARE a death trap.

They didn't have budget for an engineering lab set. They spent it all on the LEDs that went into Data's head subcutaneous superstructure.
- They famously only got the engineering set built because Roddenberry insisted on writing it into the pilot episode.
  
  STAR TREK: THE NEXT GENERATION
  "THE CLOSET INCIDENT"
  INT. ENTERPRISE - MAIN BRIDGE
  PICARD (turning to Geordi) Mr. La Forge, we need more power to the shields.
  GEORDI On it, Captain.
  Geordi hurries to a small, inconspicuous closet at the side of the bridge. He opens the door and steps inside. The closet is cramped, filled with various cleaning supplies and equipment.
  INT. CLOSET
  GEORDI (whispering to himself) Alright, let's see what we've got.
  The lights in the closet flicker, and a low hum of machinery can be heard.
  INT. MAIN BRIDGE - CONTINUOUS
  The crew on the bridge looks puzzled
  WORF (raising an eyebrow) Did he... Go into the closet?
  PICARD (trying to maintain composure) Starfleet decided the production was too expensive.
  Riker stifles a chuckle. Suddenly, the console beeps and the shields increase power.
  PICARD (exhales with relief)
  Geordi emerges from the closet
  GEORDI (tapping his combadge) La Forge to bridge, power levels are stable.
  PICARD Nods awkwardly.
  PICARD Excellent work, Mr. La Forge.
  The crew exchanges amused glances.
  FADE OUT.
  
  Was it installed on Tuesday?
- If it's dangerous enough to risk the ship, they should probably do that in a shuttlecraft far away from the ship or on some uninhabited moon or something.
  They have those sets.
  
  Probably the only thing that made sense in Into Darkness.

Or Data standing right in front of the path of the phaser beam right behind whatever device is supposed to stop it.
It would be like holding a new piece of armour plating technology that has never been tested before, holding it over your chest and asking your buddy to shoot a rifle bullet at it to see if works.

  In my day, we made the redshirts wear the cup.
  
  Is this Sam Kirk? .... I guess we now know how he died.
- People have literally died doing that.
