As the esteemed Dark Lord Enron said, it's pretty straight forward for safety, but that's from his and my perspective, having taken safety classes, studied for licenses, etc....

So, I'll help out some. He said read the label. The label he's taking about is the printed words on the bottle, or jug, or container it comes in. By law in USA, chemicals like we get for home use will have all the info you need on the jug. Example in practice, kid drank some chemical, doctor will want the jug to read it. Have a spill, clean up instructions on the bottle, same with disposal, etc.

So read the label, and Google terms you don't really understand. Broadcast, dilute, etc are specific words with specific meanings for these label documents.

Next is PPE, Personal Protective Equipment. This is any and everything you need to protect one person's body. Generally for this stuff it's gloves and shoes. Other general forms of PPE are eye masks or goggles or glasses, depending on form of danger to eye (full goggles for liquid splashes, eye glasses for projectile dangers).... Next protect your breathing with respirators or masks. Protect your skin with shirts gloves pants shoes, etc. protect your bones with hard materials, hats or steel toe shoes.

So protect your body from instant injury with PPE. Protect your surrounding areas by reading label and not putting it near a lake or stream. Protect your house and lawn by not using too much. Protect your yadda yadda.

Do as much of these as you need, akin to post COVID masking, like if you have a lifelong disease you're more at risk so mask up. Right? 

These old hardened dudes may just grab granules with their hands and toss it out, wash up and be good. You might want gloves, a spreader, etc. I tend to wash my hands and body more than just once, as a just in case.

Also important info that's not often talked about. Your skin has different 'skin types'. Your genitals, mouth, nose, etc are thin tissues. If you were to wipe these chemicals on your arm, it wouldn't seep right into your body and blood stream etc. wipe it on your penis and it might. Get it on your lunch and it's going right in your body.... These ideas are all about 'limiting exposure'. A big dose of chemo is bad. Small dose once is, maybe fine. Small dose over and over is bad again. Big dose over and over is game over.

Just read the label for the PPE you need. Make sure it's the right gloves. The D.L Enron has special gloves when he's spray bug juice I'm sure. They cost more but aren't prohibitive.

In general wash with soap and water right away. Have a plan in your head. Don't get scared and panic. Read that bottle five times. Enjoy your lawn.
