School Infection Control Handbook - 2010

Chapter 5: Safe Use Practices

x Child health and safety o The Agency for Toxic Substances & Disease Registry Medical Management Guidelines provides specific information on the effects of bleach on children: 3 “Children exposed to the same levels of gases as adults may receive a larger dose because they have greater lung surface area to body weight ratios and higher minute volumes to weight ratios. Children may be more vulnerable to corrosive agents than adults because of the smaller diameter of their airways. In addition, they may be exposed to higher levels than adults in the same location because of their short stature and the higher levels of chlorine found nearer to the ground. Children may also be more vulnerable to gas exposure because of increased minute ventilation (respiration) per kg and failure to evacuate an area promptly when exposed.” o Children have accidentally ingested bleach. The American Association of Poison Control Centers recorded over 50,000 calls regarding chlorine bleach poisoning events in 2007, making it one of the most common household substances reported to the poison control center. One third of these calls concerned children accidentally ingesting chlorine bleach. 4 x Employee health and safety o Bleach in a concentrated form can cause irreversible eye damage and skin burns, and requires the use of an eyewash station to flush eyes for 15 to 20 minutes. It can irritate mucous membranes and the respiratory system if inhaled, and can trigger respiratory conditions such as chemical irritant–induced asthma if there is prolonged exposure. 3 o Recommended staff handling of bleach for daily preparation requires training, a ventilated dispensing area, tools that help measure the correct amount of bleach, such as dispensing pumps, a funnel, and the proper use of personal protective equipment (PPE), including nitrile or rubber gloves and chemical splash goggles. See Chapter 5.C. Protocol for Safe Use of Bleach . x In a school setting o Bleach degrades metal and other incompatible surfaces. o It may damage fabrics and floor finishes. o Bleach is unstable in storage, so it should be purchased monthly. o A bleach solution must be mixed daily because the germicidal effectiveness of bleach in solution degrades after 24 hours. Summary Note: Chlorine bleach should be used only when proper precautions are followed and when safer alternatives are unavailable or regulations require its use.
