What is the corrosivity of a 1% sodium hydroxide solution? If it is this concentration, is it still necessary to use a spray eyewash station?
It’s slightly alkaline; the pH value can be calculated simply. If it exceeds 9, it is recommended to use a spray eyewash station
It is not highly corrosive, but a spray eyewash station is still necessary.
The corrosivity is very low now, but an eye washer is essential; otherwise, the inspection cannot be passed
A 1% sodium hydroxide solution should have a pH value of 14. If you don’t believe it, go and measure it yourself. An eye washer is essential
