Liquid changes from beige to red during neutralization, then returns to normal when neutralization is complete; helps identify the best time to handle with the least amount of risk Safer to use than caustic soda neutralizers which can form a poisonous gas by-product Liquid formula works at an efficient 1:1 ratio, generating less gas and heat than traditional powder neutralizers; safer to use and requires less product per spill More versatile than powder-based neutralizers; liquid can be sprayed on vertical or perforated surfaces, even atomized to help minimize vapors Use 1:1 ratio for neutralization up to 49% concentration of hydrofluoric acid Opened shelf life, if sealed properly, of 1 year
