INVISA AND GUARDIAN POOL FENCE SYSTEMS ANNOUNCE JOINT DEVELOPMENT OF FIRST SWIMMING POOL FENCE WITH "PARENT ALERT" TO INCREASE SAFETY AND PREVENT CHILD DROWNINGS IN BACKYARD SWIMMING POOLS

This document is available in .PDF format Guardian is the largest manufacturer of swimming pool fencing in the US. The market for swimming pool fences is growing at approximately 20 percent per year. Drowning is the leading cause of death of children ages 14 and under in Florida, California, Arizona, Texas and Hawaii and four other states. Two-thirds of all drownings occur in the summer between May and August. In the United States, each year about 1,150 children in this age group drown. Between 1990 and 1998 there were 5803 children five years of age or under that were drowning victims in the United States. Most States, including Florida, Texas and California, have laws mandating swimming pool fences. However, many experts warn of the important role that parents play in preventing swimming pool accidents. Nationally, drowning is a leading cause of unintentional injury and death among children ages 1 through 5. Steve Sadinsky, President of Guardian Pool Fence Systems, stated, "We have been aware of Invisa's unique sensing technology for a number of years now, and are very excited about the opportunity to partner with Invisa. Through our joint efforts, we are on a mission to create significant increases to pool safety by combining InvisaShield with our swimming pool fencing products. We expect this new product to result in a quantum improvement in safety around backyard pools. If it results in helping parents prevent even just one child from drowning, then the effort will have been worth the time and energy put into this joint venture. Guardian Pool Fence Systems has always put safety first by building and selling the most technologically advanced pool fence system available to the residential market today. We look forward to bringing the resources of both our companies together to make the most dangerous area in many homes materially safer." Carl Parks, Vice President of Operation for Invisa, stated, "We have long recognized that the swimming pool market represents a big opportunity for Invisa's technology. The need for safety solutions based on parent involvement is overwhelming. With pool fencing being mandatory in some states, and with the continued high incidence of fatal accidents we could not find a more worthy or suitable application of our combined engineering talents. We are pleased that we could establish a strategic relationship with Guardian Pool Fence Systems, one of the largest and most respected swimming pool fence manufacturers in the US. We expect this joint development project will soon represent a significant addition to Invisa's and Guardian's future growth."
