Any form of digging can lead to the sides of the holes, or trenches, collapsing just like sand will fill a hole you dig on the beach. This is extremely dangerous for anyone unfortunate enough to be stuck inside the trench as hundreds of pounds of debris can crush them. Trench shoring is the answer, and the equipment required can be bought or rented, depending on the construction needs.
As mentioned before, falling debris as small as a hammer can lead to permanent injury or death. Any person walking around a construction site should be required to be wearing a hard hat. In a perfect world, no one drops heavy things from 4 stories above ground. Unfortunately it happens all the time, and without a hard hat, the results can be fatal.
Along with construction equipment, proper clothing should be worn for proper situations. Bulwark FR is needed for anyone entering the line of duty involving fire or hot substances. Simple carpenters jeans are fine for anyone doing routine construction work. Even if you need some better shoes or sunglasses for your job, bring them in advance so you don't do any long term damage to your body. Just prepare well in advance so your body doesn't take a toll.
