Explanation:
First of all, you should be wearing proper PPE when handling acid, including a lab coat, large viton or butyl rubber gloves over nitrile gloves, apron, safety eye goggles (goggles!! not just safety glasses with an eyeshield), and face shield. You should be working in a fume hood with the sash closed in front of you as much as possible. This combination of engineering controls and PPE will help avoid a lot of big problems.
If you do get it on yourself anyway, then the response depends on the severity. If it’s a little bit on your hand or arm (few drops), then wash under cold water for 15–20 minutes. If you do that right away, you should be fine other than a possible small burn. If it’s a little bit on face, near eyes, or in eyes, then use the eyewash to rinse acid from your face/open eyes for at least 20 minutes or more.
If you spill a large quantity on yourself, such as all over your clothes so that it is absorbing and touching a large part of your skin (but not endangering your face/eyes), then you need to immediately take off ALL your contaminated clothes and get under the safety shower in the lab. This is no time for modesty - your dignity will recover, but severe acid burns all over your body will not. Noone familiar with lab safety will hold this episode against you, I assure you - it is absolutely necessary for your safety in the event of a large spill.
If it is all over your body including face/eyes, strip off all your contaminated clothes and use the eyewash station to rinse face and eyes first while intermittently using cold sink water to rinse any other body skin exposed to acid (splash water from sink onto exposed areas and use a paper towel to blot or wash away any excessive acid on the skin - use a bucket or beaker to pour water over the back of yourself if needed). Face/eyes come first, in my opinion (that’s what I would prioritize for myself, anyway); but you want to avoid serious burns to the rest of your body, as well, by diluting the acid on your body with sink water or paper towels soaked in sink water as much as possible. (This last paragraph is my personal best estimate of what to do in a really bad acid spill situation that is all over your body, face, and eyes - check with your lab safety officer to verify your own lab procedures and best practices for really bad acid spills over the entire body.)
I hope this helps someone.
Answer:
You can use water to wash away the acid.
You can also apply neutralisation to cancel the acid and alkali each other out. For examples, bee sting (acidic) neutralised by soap (alkaline), hydrochloric acid in our stomachs (acidic) neutralised by a medicines called antacid (alkaline), acidic soil because of acidic rain (acidic) neutralised by lime (alkaline).
