Let's assume I am wearing a labcoat for two reasons:
- Prevent the various bacteria, proteins, skin cells and substances on my clothes and my skin from contaminating my experiments.
- Prevent various dangerous things from the experiment getting on me, and ruining my clothes or endangering my health (eg. toxic chemicals, pathogenic bacteria, ecotropic virus, etc)
A labcoat is an imperfect, but valuable barrier against such hazards. Perhaps a droplet of some Nasty Substance™ ends up flying towards my arm, but instead of getting on my exposed skin, hits my labcoat.
However, what happens when I take off my labcoat? My gloves, which have just been in contact with lots of Nasty Substance™, go through the sleeves of the coat, possibly smearing the substance all over the inside of the fabric. When I put on the coat again the next day, now my skin is in contact with these smears.
I could remove my gloves before taking off the labcoat, to avoid this smearing. But this time, I have to touch the labcoat with my bare hands as I remove it. Remember the Nasty Substance™ that was stopped when it splattered on the outside of the fabric instead of my skin? What if I know end up touching that?
I know that for truly dangerous conditions, there is specialized equipment and detailed procedure. Even at BSL2+, traditionally disposable labcoats are required, rendering the issue somewhat irrelevant. So let's assume the highest level below that, BSL2, as the context for answers.
In short, what is the correct way of putting on and taking off gloves and non-disposable labcoat when working in BSL2 conditions?
