Due to the limited amount of time YouTube videos are allowed to take up, there can definitely be lot of information that gets left out - agree with you there, zzgergzz. An 8-10 minute video could never cover all of the "what if" scenarios, like the one you mention regarding Type A soil, that pertain to excavation safety. These videos are meant as a general overview and as such, cover the broader topic. Our complete safety courses on this topic go into much greater detail.
Videos like these can be a valuable tool...The problem is that some things get left out. NO SOIL IS TYPE A if it is fissured or cracked or subject to vibration. Contractors can get in a lot of trouble classifying soil as type A. because they will not use shoring.
