If it only enters the mouth and is not swallowed, spit it out immediately and rinse your mouth with water.
If swallowed by mistake, you need to pay attention to your own body's reaction, if there is a burning sensation or other irritating reaction, you should immediately seek medical attention.
Some domestic cutting fluid contains high concentrations of nitrites, heavy metals and other harmful substances, daily skin contact are very harmful, not to mention into the body. So be careful!
If you need to sample the cutting fluid at the production site, don't use a beverage bottle - it's easy to mistake it for a drink. This is especially true for fully synthetic cutting fluids that are completely transparent and look no different than mineral water.
There was a rumor that one of Basalt's salesmen drank cutting fluid in front of a customer to prove its human health and environmental friendliness. This is the wrong approach in every sense of the word! After all, chemical products are not beverages. Even the vegetable oil-based emulsion products that we use extensively in the processing of implantable medical devices (e.g., artificial joints, bone nails, dental implant bases, etc.) are not drinkable.
