I should have been more clear. ALL of us cleaning people, whatever your specialty is, should work safely and carefully. Few of us can afford the kind of insurance to pay huge medical bills if we get hurt on the job!
One thing to think about is this: Not all damage to your body SHOWS on the outside or FEELS on the inside - until perhaps it is too late. Using many chemicals without proper safety precautions can hurt you, and it could happen suddenly, or over a long time. Not much different from smoking cigarettes or cigars, or drinking too much, I guess. Getting many chemicals on your skin can burn you or damage your skin. Breathing in many chemicals can sort of "burn" your lungs, much as smoke does. Not wearing gloves consistently is a big factor. Now, I admit I HATE wearing gloves!!! Why? Because my hands sweat more when I wear them, and all that salty water ends up causing cracks in my finger skins around the nails. But I DO wear gloves, because the alternative is dangerous. We cleaning people deal with bacteria and viruses on all surfaces daily! I keep hand lotion made for problem skin in my car and on breaks I use it, after drying my sweaty hands.
