Y'all, it's just a stock photo.
You have posted some general safety tips, a good thing. Then you included a "specifc" photo showing a procedure that is not completely safe, showing a missing blade guard, not a good thing.
For those of us who already know the safe operation of woodworking tools, it won't matter, but for those just starting out .... who I think your post is intended, it gives a mixed message. If you acquired this info from a generic source as opposed to speaking from years of personal woodworking experience, so you are gonna get some flak... just sayin'.
One of the most important safety tips I know from 50 years of using a table saw, is to place ONLY straight and flat work on the table and against the fence. IF the work should shift or twist because it is NOT flat and straight you will most certainly have a dangerous kickback. Kickbacks are the most common table saw mishap, occurring far more often than blade cutting flesh injuries, because they are just not reported and don't involve emergency room attention.
Another important table saw safety accessory/device is the splitter or riving knife which maintains the work against the fence to prevent it from walking away and causing a kickback. It also keeps the kerf open to prevent binding when a cut in made in "reaction" wood closing and binding the blade under power.
Using the correct type of blade, for cross cutting or ripping is also an important safety issue. Trying to rip with a cross cut blade will cause it to overheat and bind because the gullets aren't deep enough to clear out the chips and there are too many teeth with not enough offset. Conversely, crosscutting with a rip blade will just not give a clean cut, but there are no safety issues.
A full explanation of the table saw safety tips and rules would require a "book" with photos included for each safety aspect, way too much for a post on this forum, but I have included the basic ones I have learned over the years.
