How Does Bear Spray Really Work?

The burning truth about bear spray

You might carry around your trusty bear spray on backcountry trips, but have you ever wondered what makes it so effective? If you haven’t, you’ve probably never been downwind of a blast.

“The spray cloud causes an involuntary closing of the eyes and irritation of the respiratory system, causing choking, coughing and constriction of the airways,” says George Hyde of Counter Assault, the first bear spray to be approved by the Environmental Protection Agency. It’s a nonlethal yet debilitating response. Sneezing, bronchoconstriction, apnea, laryngeal paralysis and temporary blindness join the litany of unpleasant effects.

According to Pride Johnson, President and chemist at Counter Assault, the root cause is inflammation. “The active ingredient in bear spray gets into the mucus membranes and makes the tissue swell,” he says. Dilation of the capillaries causes instant inflammation of the respiratory system. “Pepper sprays have an immediate reaction, whereas tear gases can take five to eight seconds to start working,” he adds.

Originally developed in the 1960s as a defense against aggressive domestic dogs, the active ingredient in bear spray is capsaicin, a natural chemical isolated from the seed capsules in certain red peppers. One ounce of purified capsaicin diluted in 750 gallons of water can make your tongue burn.

The capsaicin compound found in bear spray is mixed with oil to form Oleoresin Capsicum (OC). Bear spray manufacturers combine OC with a liquid so it comes out of the can in a foglike spray and add a propellant—only one to two percent of the contents of a can are pure capsaicin.

While people use a variety of deterrents for protection, including firearms, signal flares and an assortment of noisemakers, red pepper sprays remain the most effective, according to Stephen Herrero, professor at University of Alberta and author of Bear Attacks: Their Causes and Avoidance. An incident analysis by Herrero and his colleagues found that pepper spray stopped charging black and brown bears in 94 percent of cases.

PakBoats PakCanoe 160 Review

PakBoats PakCanoe 160

A canoe that can comfortably take you from big lake waves to remote rivers and only takes up half the trunk sounds impossible. But Pakboats’ PakCanoe 160 makes it happen. This hand-assembled canoe is an ideal wilderness boat that also functions well as a general-purpose day-tripper.

Formed of heavy-duty synthetic canvas coated with high-abrasion-resistance PVC, PakCanoes are held under tension by an interlocking skeleton of tubular aluminum. Inflatable air pockets help make them rigid.

While it took a little sweat and some skinned knuckles to get the 160 put together the first time, we shaved down the straightforward assembly to a lean 45 minutes on our second try. Taking it apart takes less than half that and, disassembled, the 160 stores in a 35- by 17- by 13-inch bag—our publisher thought it was a new cooler sent for review. Don’t worry about having to put it together every time you want to paddle, PakCanoes can ride on the roof while assembled, just like their hard-shelled cousins.

On the water, the 160 is stable, easy to maneuver and gets up to top-speed quickly. There’s plenty of space for several weeks worth of gear if you’re smart about your packing. The seats’ location and height are easy to adjust and the simple foam kneepads are surprisingly comfortable.

Alv Elvestad, who founded Pakboats in 1995, steers those interested in a dedicated tripping boat to the larger 165 or 170 models, but says the 160 is a popular option for those who take shorter wilderness trips as well as longer ones.

“It’s a very seaworthy boat and people feel very comfortable in it because of its stability— it’s designed to deal with the rough conditions that come with long trips.” The flexibility of the fabric hull keeps the boat drier in rough weather and on the river, as the boat flexes and runs over waves instead of through them.

The most common reason people buy PakCanoes is because their packable nature makes them easier—and cheaper—to take to remote regions. “The cost of float plane flights nudges people into using Pakboats on the really remote trips,” says Elvestad.

While he’s used to fielding questions about the durability and reliability of the hand-assembled boats, he says their exploits speak for themselves. PakCanoes have been the boat of choice for decorated explorers on first descents on everything from northern Canadian rivers to tropical Bolivian ones.

“The kinds of trips people do with these boats, you would not take a boat on this type of trip if you couldn’t rely on it,” he says.

Whitewater Festival Risk

Death at Moose Fest.

This article originally appeared in Rapid magazine.

When a tethered swimmer finally pulled William De Angelis from a sticky hydraulic on New York’s Lower Moose River last October, it was too late. The 62-year-old New Jersey man was already dead, his neck broken by the violently recirculating water.

De Angelis’ death was the tragic finale to a carnage-filled whitewater weekend that witnessed a shocking number of near drownings and more than a dozen hospitalizations each day for injuries ranging from dislocated shoulders and concussions to knocked out teeth and lacerations. All this at an event billed by local outfitter and promoter, Mountainman Outdoor Supply Company, as “New York’s Premier Whitewater Festival.”

The brainchild of New York whitewater pioneer and river advocate Chris Koll, Moose Fest first kicked off in October 1994. The American Whitewater-backed event brought hundreds of boaters to the then little-known Moose River at Old Forge, New York, to enjoy the recreational dam releases for which Koll and others had fought and won. Since then, the numbers have stayed strong, but with the financial realities of declining industry participation, the festival structure has grown more nebulous. There’s no longer an official organizer or venue, not even a website; paddlers simply mark their calendars and show up.

“The event runs itself,” says Koll, who still coordinates the releases and posts flow information on Internet forums.

At typical flows, the Lower and Bottom Moose are challenging class IV–V runs that should give even experienced boaters pause. Yet Juraj Kobzik, an Ottawa-area paddler who attended his first Moose Fest last year, writes on his blog that many newcomers observe a festival tradition of running Agers Falls—a 20-foot drop above a bumpy run-out of holes and slides—blind. He goes on to describe the scene below the falls: “About 20…people ran the drop ducky-style and…they were all pulling their skirts and swimming.”

Former Pyranha rep, Matt Hamilton, has attended the event every year for the past 15 and says, “I don’t think I’ve ever been to a Moose Fest where someone didn’t end up at the hospital. There’s always some sort of carnage.”

It doesn’t take a statistician to figure out that more paddlers on the river equates to greater chances of paddlers getting hurt or even killed. But the higher incidence of injuries at events like Moose Fest is more than just a numbers game—it’s a product of human nature.

In his pivotal 2002 article, Heuristic Traps in Recreational Avalanche Accidents, decision science researcher Ian McCammon identified six common decision-making pitfalls that contributed to the 715 accidents he reviewed. While McCammon was seeking an explanation for why experienced backcountry skiers were making really basic mistakes surrounding avalanche safety, the traps he found are just as prevalent on the river.

One in particular—complacency in familiar environments—seems to have played a significant role at last year’s festival. A lightning strike earlier in the season incapacitated the dam and the flow on the Bottom Moose rose to 5’7”—well above the typical 3–4 feet—festival weekend. “We tried to warn people that with the dam off, the river is a different animal,” says Koll, but many paddlers simply didn’t register that an “easy class V” run had become a “full-on class V” monster.

Laurence-Olivier Neron, a Quebec open boater who became trapped in a hydraulic on the Bottom Moose after failing to wait for an all clear signal and colliding with another boat, says he thinks the charged atmosphere of festivals provokes the use of poor judgment. “In my excitement, I disrespected many basic whitewater rules that I knew and usually respected,” he says. Neron was luckier than De Angelis; he lost consciousness, flushed out of the hole, and was rescued by friends downstream.

Is Moose Fest more dangerous than other events? Hamilton doesn’t think so. He cites observing similar injury rates at West Virginia’s Gauley Fest. Koll agrees, “I think [Moose Fest] has more of a reputation for carnage in the bars than on the river.”

Festival crowds mean more learning opportunities and more throw bags and boats to help with rescues, but they also mean more exposure to risk. Koll believes safety will come from respect, “Enough paddlers got spanked [last year] that I think people will approach the river with a little less cavalier attitude.”
