i used to work for caterpillar op on the north east late 80's early 90's, fitting gear boxes on new trucks & always felt ill from the gearbox oil, laying on my back in pools of the stuff & getting home
with big rashes on my back from wet oil soaked clothes, the smell of the diesel & oils would make me sick most of the time, we had barrier cream supplied but most of the staff didnt use it back then.
my hands would split & get sore. on my days of i used to fix cars too & engine oil & gearbox oil would & still does make me feel sick.so glad im in IT now & have been since 92. ill never go back to hard graft ever again.
