I visit a lot of contractors so I usually have to sign one of these sheets each time I go. I've actually seen the Time In/Time Out reversed on some of these sheets. Never understood why. That's minor though because you tend to follow the people ahead of you anyway. If it's a halfway filled up sheet you will see one column already filled (IN) and the other column unfilled because they haven't left yet. If you are the first in that day then a quick scan of the times already entered on the sheet will tell you right away which one is IN vs OUT. And if it's a fresh sheet you will read the column titles thoroughly before filling it in. That's no biggie. The other one though (ear plug box) should be put back on the sheet (IMO). Now instead of the visitor being aware that they need ear protection, the guards or the person escorting the visitor will have to remind that person. Then again the person who escorts the visitor will almost always remind people to wear protection and there should be warning signs plastered everywhere (particular on doors to danger areas).
