Agreed, WJY, but consider the sailors in the engine room of a ship powered by a large triple expansion steam engine.
The link below is to a video showing the triple expansion steam engine in a WWII Liberty ship.
This engine produced about 1,800-1,900 SHP and could propel a Liberty ship at about 11 or 12 knots.
Operating and maintaining such engines required sailors to work in close proximity to the moving parts. These men knew what they were doing long before there was an OSHA.
FWIW, this is a small marine triple expansion steam engine. The triple expansion engines of the WWI armored cruiser SMS Blucher produced nearly 38,000 SHP but it was not enough. German intelligence failed to determine that the British had developed a new type of ship, the battlecruiser, which was turbine powered and lightly armored but mounted the heavy guns of a battleship. The SMS Blucher, the largest, fastest, most heavily gunned, and most heavily armored, armored cruiser built by anyone was obsolete when laid down in 1907. Though she could make over 25 knots, she was run down and sunk at Dogger Bank in 1915 by newer, faster, turbine powered, British battle cruisers mounting much bigger guns. Imagine the sailors in the engine room trying to get every last HP out of their engines during the battle. Most of her crew perished as she sunk.

After Captain Cook's exploration of the east coast in 1770 the British Government decided to establish a penal colony in Australia. The first fleet arrived in 1788 and consisted mainly of convicts who were poorly equipped and new little of farming techniques. The colony remained far from self-supporting and it was not until the early 1800's that things started to improve. Free settlers started to arrive, they followed the explorers across the mountains and where land was suitable set up farms. T
