Your work on a particular day might not involve the use of corrosive chemicals. So what if you are walking to your work location and notice a can of solvent lying tipped on its side and a mess on the floor? What should you do? Stop and report it, even though it’s not your spill.
What about reporting your own spill if it seems like nothing, and you cleaned it up? Your management still needs to know about the spill. For one reason, if people are spilling things and not reporting it, how is management to become aware that something (perhaps inappropriate solvent containers) is wasting time and endangering people?
Also, you might not fully understand the full effects of that spill. Or maybe there’s some “gotcha” you didn’t know about when you cleaned it up. Always report a spill immediately. If your company respects safety, reporting a spill won’t get you into trouble. But not reporting a spill is a serious offense.
