Every shop should have a first aid kit. Ideally it should never have to be used but this is not an ideal world and where work is being done bandages will be needed, splinters will have to be removed and ointment applied. In all my years in the trades there have been few jobs where I did not spill at least a few drops of blood as sacrifice to the gods of construction.
In large commercial shops (i.e.: those with huge insurance premiums) safety is a high priority issue. Supervisors will keep an eagle eye out for violations. Weekly meetings will be held and anyone who screws up while violating the rules will be in for some serious S.H.I.T. (Special High Intensity Training) at the very least.
But what about the smaller shop and, in particular, the home work shop; is safety less of an issue there. No.
True, you may not have the big equipment that's just waiting to grab you and turn you into chopped pork but there are things you must be aware of to avoid ruining your day or your life.
Let's start at ground level. What's under foot? Are you constantly tripping over extension cords or air hoses? Is that pile of scrap around the miter or table saw causing you grief? How many times have you stepped on the male ends of your power tools and bent the leads?
I think you see where I'm going with this. If at all possible get it out from under foot. Look at your power set up and see if another outlet or two (or six) might make your life easier (and help preserve the plugs of you tools). If your air compressor is a large part of your day consider flying your air hoses over head. Those coiled hoses are a colossal P.I.T.A (Pain In The Aft) on the ground but can be useful coming down from above. And while I've often found it handy to have a few pieces of scrap lying around within reach, that "few pieces" can become clutter and a nuisance in short order.
To sum up, take a good look at your shop. Take note of what generates damage or profanity and take the steps necessary to make your life better...and safer.
That's all for now. I'm not done with this subject.
