Edmonton Police Services tactical officer Scott Innes was driving away from a raid at a suspected drug house when he realized something was wrong.

鈥淚 started to overheat. I started to sweat. I felt my pulse rate was starting to increase,鈥 he told CTV Edmonton on Monday. 鈥淚 suddenly started to feel ill.鈥

Innes was set to lead a group of officers into the home. Instead, he found himself outside, patting down and searching a suspect with his bare hands. He had no idea the biggest threat he would encounter that day was one he could not even see.

鈥淒uring that pat-down search, I pulled various items from his pockets. I placed them on the bumper of my vehicle,鈥 Innes recalls four months later. 鈥淚t was just a momentary lapse in my judgment.鈥

Alone in southbound traffic on Wayne Gretzky Drive, he realized one of the powerful synthetic opiates that have become notorious for their lethal strength was taking hold. A colleague responded to his call for help, jumped into his truck, and rushed him to the nearest hospital.

Medical staff needed to know what they were dealing with as soon as possible. A phone call to investigators prompted a field test of the items Innes pulled out of the suspect鈥檚 pockets.

鈥淚t tested for fentanyl right away,鈥 Innes said.

Fentanyl is a powerful prescription painkiller about 100 times more toxic than morphine. , two milligrams of the uncut drug, about the size of four grains of salt, is enough to kill the average adult. Unintentional contact through touching or inhaling can cause death.

鈥淭he intervention that was required at that point was to cleanse myself of anything that could be contaminated, my uniform. They made me shower,鈥 Innes said of his time in hospital. 鈥淚n my mind, it was a close call.鈥

He鈥檚 resolved to never leave his gloves behind again.

Nicole Wetsch, an occupational health and safety consultant with the Edmonton Police Service, said officers are receiving more safety gear, including respirators, gloves, eye protection, special masks to limit exposure during CPR, and nasal spray Naloxone to treat exposure incidents.

Edmonton Police Service drug expert, Det. Guy Pilon, said Innes鈥 exposure is a reminder of the importance of continuous safety training.

鈥淚t goes to show you how quickly a situation can go from something that is manageable to something that is dangerous in a fleeting moment,鈥 he said.

For Innes, the experience underscores the new dangers that officers face on the frontlines of the opioid crisis.

鈥淥f all the things that I have been through on this job, that鈥檚 the thing that will be my demise?鈥 he asked. 鈥淭hat鈥檚 all because I didn鈥檛 put my gloves on.鈥
