Different gloves for different jobs.

For construction, after hurricane clean up and digging through rubble I plan on using a stack of polyester knit gloves with latex, actually I think it is modified latex because it doesn't seem to be degraded by oil, be sure to check, applied to the palm and fingers. I have used these shifting busted concrete, used lumber and tree limbs and found they wear well and prevent cuts without being too hot. They can be washed several times after they get nasty or slimed. They are cheap, roughly $2 a pair, and seem to last longer than leather if conditions are wet.

For keeping blood or body fluids off nitrile examination gloves are good. Better than latex in my estimation because they are more resistant to oil and don't tear so easily. If the situation combines hard use with body fluids the poly/latex gloves can be worn over the examination gloves.

For chemical resistance or when the job involves work likely to tear a nitrile glove high cuff PVC gloves are what I use. These may replace nitrile examination gloves in austere environments because they can be cleaned and reused many times if cared for. It is pretty old school but it was only in the 40s that surgical gloved were disposable. Before that gloves were cleaned and reused like everything else.

If things go south in a big way for a long time reusable glass syringes, needles that can be resharpened and reusable gloves might become valuable commodities.
