The Wilson family was enjoying a long weekend of camping near their favorite lake. Betty had been hearing a lot about West Nile Virus and mosquitoes on the news all summer and made sure she remembered to bring a new aerosol can of insect repellent containing DEET. As the sun set, the mosquitoes were out in full force, ready to bite. Her 17 year old son, Adam, asked her for the repellent can. Betty carefully read through the product label and handed it to Adam, explaining only to use the repellent on exposed skin, not to spray it directly on his face, and to wash his hands when he was done. Adam used the product as instructed and set it down so he could go wash his hands.
Doug, Adam's 4 year old brother, had watched Adam use the spray and didn't want mosquito bites either. Doug picked up the can, pushed down on the nozzle, and sprayed his face. Doug's eyes immediately started to burn and sting. He dropped the can and ran screaming to his Mom. Betty calmed Doug down and noticed he smelled strongly of repellent. Adam found the repellent can on the ground where Doug had dropped it and brought it over to his mom. Betty realized Doug had sprayed the repellent into his eyes! She read the first aid section of the product label and flushed Doug's eyes with clean water for 15 minutes. She loaded Doug into the car and rushed to the nearby hospital, being sure to take the repellent container along to show the doctor.
