Bleach is a chlorine-based chemical solution that is widely sold in grocery stores and has numerous household applications, but it can be very dangerous. In addition to the household variety, there are also several formulations of more potent industrial bleach, and their health risks are even greater. It is especially important to avoid exposing the skin or eyes to bleach when handling it, as such an exposure can cause severe tissue damage.
Exposure of common household bleach to your skin is not likely to have immediate effects, especially if the bleach has been diluted with water, according to "CRC Handbook of Laboratory Safety" by A. Keith Furr. The longer the bleach is left on your skin, however, the more likely it is that you will begin to experience burning, itching and other types of irritation. If the bleach is left on your skin for an inordinately long period of time, it can cause pigment lightening and permanent tissue damage. Stronger industrial formulas of bleach will produce the same results, only in a shorter amount of time.
Getting bleach in your eyes is much more serious than getting it on your skin; damage can occur much faster, and the worst-case scenario can be more debilitating. According to Furr, pain and irritation will be immediate and proportional to the potency of the bleach. Irritation and damage to your eye tissues will continue until all of the bleach has been rinsed away, and pain and tenderness is likely to continue for hours afterward, even in cases of mild bleach exposure. If first aid is administered immediately, permanent damage may be avoided. If bleach is left to linger or if the bleach is very potent, more serious consequences can include vision damage and even loss of the eye or eyes.
The immediate application of first aid is essential to minimizing skin and eye damage. The Clorox Company, makers of Clorox Bleach, recommend addressing skin exposure by washing the skin with water for 15 to 20 minutes. If you get bleach on clothing and it soaks through to your skin, remove the clothing first before rinsing. If no irritation develops, professional medical treatment is not necessary. If you get bleach in your eyes, hold your eyes open and flush them with clean water for 15 to 20 minutes. If you're wearing contact lenses, stop to remove them after about five minutes of rinsing, then continue. Always seek professional medical attention as quickly as possible after eye exposure. Immediate rinsing is the highest priority, but if you can get someone to summon medical attention for you while you're rinsing, do so.
To prevent exposure of these types, Furr recommends wearing impervious rubber gloves and safety goggles.
