18 Canadian Occupational Safety | www.cos-mag.com Serious Labs. The particular pro- cess is very hard to train on and all of the company's contractors need to be ticketed on it, Colvin says. "It's very expensive to do that type of training because you have to shut a place down to practise it. We are basically building that facility (virtu- ally) that needs to be locked down for certain maintenance to occur," says Colvin. "So now that instructor, who might be based in Houston, can have a team of 50 guys all getting walked through that training course that he wrote, and is specific to their needs, right in the very environment." The company is developing a mobile app so the petrochemical company's workers can drop their smartphones into devices such as Google Cardboard or Samsung's Gear VR — which turn smartphones into virtual reality viewers — to receive the training. Augmented reality — when digi- tal images are superimposed into a user's view of the real world — is also gaining traction in the safety training space. NORCAT has developed a fire extinguisher augmented reality pro- gram where individuals use an actual fire extinguisher with an augmented reality screen attached to it. The user can choose an item in his workplace and "set it on fire" — or so it would appear on the screen. The user then physically has to pull the pin, aim, squeeze and sweep. "(It will) determine are you holding the extinguisher at the right angle? Are you sweeping at the right pace? And the fire continues to grow and evolve like it would in a real situation, but you are also physically holding the extin- guisher to have that real experience because some of these extinguishers are quite heavy," Duval says. BENEFITS Undoubtedly the greatest appeal of virtual reality safety training is the fact that workers can be exposed to very high-risk situations in a 100 per cent safe environment. They can be trained for incidents that they could never be trained on in a classroom or even mock training facility, says Colvin. "You may never encounter that situ- ation for two years on the job site... (but) it becomes your default behav- iour to go through the correct series of things you were trained on rather than 'I've never been in this situa- tion before. What do I do?' That's when people panic; that's when people get hurt." Knowledge retention is very high with virtual reality programs. "It is so vivid, so real and immer- sive that it's burned into that fight-flight mechanism in their brains," Colvin says. "They know what it feels like to have that thing start to tip over with them in it. They know what it's like when they hear that smash of the basket hitting the ground." Even after they have completed a virtual reality training program, indi- viduals are often talking about it with their colleagues or noticing things in the real world that are the same as the virtual world, which increases recall, says Duval. Virtual reality provides a good method for assessing workers' skills and abilities before they're on the job site. "These lifts, it's a big piece of equip- ment and you can get hurt on these things," says Hooter. "You don't put somebody at the controls who doesn't know what they are doing. Not only that, some people might be good at 50 feet but you get them over 80 feet and, all of a sudden, they get a little queasy." An employer might want its more experienced workers participating in virtual reality training as well because it can provide an accurate snapshot of their skills. It will prove if they do, in fact, work safely or if they cut corners, Colvin says. At a recent trade show, a very experienced tradesman tried Serious Lab's aerial work platform VR simulator and he got a very low score. "He was very aggressive, he was hard on the controls, he was very jerky and abrupt, his ride quality was terrible, his feathering of controls terrible. All of the things that not only can lead to injury but can also be really hard on the equipment," Colvin says. Aside from the safety benefits, vir- tual reality training can result in less damage to rental equipment, which translates into less downtime, he adds. COST The cost to train your workforce in virtual reality varies considerably and depends on what option you ulti- mately choose. The motion platform from Serious Labs cost US$70,000, Hooter says. Then, a monthly subscrip- tion fee is paid for the training software to ensure it's always up to date. If you're looking for a more basic VR training experience using just the headsets, Winnipeg's Bit Space Devel- opment works with companies to build applications for safety training. Its services start at $5,000 per year for two course modules and the training is compatible with a wide range of headsets in various price points. VR headsets can be purchased at retail shops or online for anywhere from $15 for the Google Cardboard to $700 for the HTC Vive. Keep in mind that not all virtual reality train- ing is compatible with products that use smartphones in the VR headset, so make sure to check with the devel- oper and find out what hardware they support. Holobuilder.com offers a complete do-it-yourself solution. Targeted to construction companies, the safety manager uses an app on her phone to record her own work site in 360 degrees. She walks around the site, making sure to consider every blind spot. Then, she uses the online web editor to enrich the job walks with warning signs, floating text, safety rules and integrated videos. Workers can access the virtual site using their smartphones and Google Cardboard. Holobuilder is offered on an annual subscription basis, starting at US$900. Another option is for employers to use a third-party training provider to train their workers. United Rentals has partnered with Serious Labs to pilot this model, which would be signifi- cantly less costly to employers than purchasing the equipment themselves. "They can take the online course for the theoretical part at home, go down and take the simulator part right at the branch and get assessed and be on the job site by lunchtime," says Colvin. Yet another option is to rent the VR equipment, which could include motion platforms and headsets, when you need it. The rentals could come with or without the training software, depending on the circumstance. This is going to be a very common method going forward, says Colvin. An online company aptly called VirtualRealityRental.co has many different types of VR equipment for rent. COS asked how much it would cost to rent 15 VR headsets for one day, and the price tag came in at US$3,450. In Canada, the company serves Calgary, Edmonton, Montreal, Ottawa, Quebec City, Toronto, Vancouver, Victoria and Winnipeg. Another decision to be made is custom versus generic training. Immersive Technologies' WorksiteVR Simulator provides training for construction equipment. Starting at US$30,000, employers receive all training materials, software and hardware, including VR display and headwear, a high-end computer, pedals and the specific hardware for the type of simulator they choose, such as joysticks for the excavator and steering wheel and bucket con- trol levers for the wheel loader. The company has offices in Fort McMurray, Alta., Ottawa and Vancouver. There are also generic mobile apps available for smartphones, accessible with products that convert the phone into a virtual reality viewer. Texas Mutual Insurance company's virtual reality safety training app, called Safety in a Box, allows users to experience the dangers of workplace accidents with 360-degree perspective video. In one video, the user is working at height and sees what it would be like if he got too close to the edge. But Duval cautions that generic solutions may not be sufficient for most companies. "It's critical that companies under- stand that investing in and getting the content right, the curriculum right and ensuring clarity on the desired learn- ing outcomes is the most important part of the training and development equation," he says. "Many organiza- tions are getting caught up trying to use new learning and development technologies and failing." Virtual reality training won't be for everyone. While the technology com- panies are working hard to eliminate the side effects, there have been reports of people feeling nauseous after using virtual reality headsets. "We have worked with a variety of different companies where some (workers) don't enjoy the experience for a variety of reasons and you need to know that," says Duval. For this reason, companies need to have alternate training methods avail- able. If an individual does not like the VR experience, similar training could be available with an avatar on a com- puter, Duval suggests. Another challenge is that there's always going to be late adopters, says Colvin. In general, younger workers are more open to virtual reality tech- nology and expect their employers to use the most cutting-edge technology, while older workers may be more hesi- tant. But once they start using it, they love it, Colvin assures. For now, virtual reality safety training is mostly seen at companies that com- plete high-risk activities, such as those in construction, mining, oil and gas and forestry. But soon it will be common in all industries, Colvin believes. "VR is going to permeate everything. How do you stock the shelves in a grocery store or how do you design something up front before you build it? It's kind of like saying 'What indus- tries might use the Internet one day?' Well, they all will." They know what it feels like to have that thing start to tip over with them in it. They know what it's like when they hear that smash of the basket hitting the ground.
