How do you prevent the black residue from metal safety pins from getting on clothes?

Answer:

They think that because they are ignorant of what a firefighter has to do. Is a high level of education required? not really. Does it help? Damn right. without education you won't get past being a basic hose monkey. Fire behavior, Strategy and tactics, Fire weather, fire predictions understanding how to place and use what you have in the best way without getting anyone killed, Hydraulic calculations, friction loss, pressure calculations, flow rates and flow dynamics ect.. and we haven't even begun to touch the EMS side of things or the being in charge or any of a dozen other specializations in various areas.
Six easy steps. 1) Before you walk through the door, always, always, always read the entirety of that day's plan. Do not ever walk into the lab without a general idea of materials needed and the order of the steps you will be following. You should also be able to recite, without thinking, the abstract and concrete reasons for the experiment. If you have designed your own experiment, do not skimp on cleanliness or detail. That is, make sure that your plan for that day is legible and easy to follow. Also ensure that your materials list is precise. 2) Once you get to your table, read the entirety of that day's plan. I know you have already read it. But, I cannot stress this enough. 3) Read the entire step, even step one, before carrying it out. 4) Record all measurements to the best of your ability. And make sure to record them as far as you can. This means recording as you work and does not mean trying to remember measurements a few minutes later. Also, you may need only two decimal places for the report, but having five in your lab book will help you, should you run into any problems. 5) I know this is cliche, but observe all safety requirements for your particular lab. Never horse around, even around safe experiments. Keep your working space as clean and clear of obstruction as possible. Do not eat or drink in the lab. Always wear your PPE (Personal Protection Equipment). Yadda, yadda. 6) Finally, do not ever stop an experiment unless you are absolutely sure that you have contaminated or otherwise fouled it. Your results may be different than those of your peers. That is fine. Confer with them later, to determine who needs to perform the experiment a second, or even fifth, time.
