Canadian Occupational Safety (COS) magazine is the premier workplace health and safety publication in Canada. We cover a wide range of topics ranging from office to heavy industry, and from general safety management to specific workplace hazards.

October/November 2015 31 Productivity can also take a hit, which is very diffi cult to measure. "It could be lost time from inves- tigating what happened. It could be running to Canadian Tire to get a tool that you broke when you dropped it. Or it could be up on 50th storey you dropped a tool you need to do a job and need to go all the way back down to get it and climb all the way back up," says Bohmbach. Public relations could be a cost if an incident makes the headlines, says LeBlanc. The employer may also accrue fi nes from the ministry of labour, as it is an employer's duty to keep the workplace safe, which includes man- aging risks of dropped objects. HARNESSES FOR TOOLS One solution is tethered tools. These tools either have a built-in connection point placed by the manufacturer or can be retrofi tted with connectors. Then, the tools are connected to a lanyard. Energy-absorbing lanyards will reduce the force associated with the dropped tool. Tools can either be connected to a worker through a tool belt, harness or wristband or anchored to a fi xed structure. As a general rule, a tool more than 5 pounds should never be tied-off to a person. "You don't take an 8-pound hammer and tie it to a body. What happens if I am swinging that hammer and it gets loose? At best, maybe it dislocates my wrist or shoulder. Worst case it pulls me over the scaffolding into a very bad situation," says Caldwell. If a worker has a tool attached to him and he needs to pass it to a col- league, the colleague can connect to the tool before the passing worker dis- connects from it, ensuring the tool is 100 per cent tied off and never has the opportunity to become a drop hazard. Employees need to be properly trained on how to use tethered tools. They must be taught how to attach the tools, use the lanyards properly and respect the weight rating of the lanyards. Tethered tools are mostly seen among larger construction companies and are not widespread in the indus- try yet, says LeBlanc. But this could change with younger workers tending to be more inclined towards safety than the veterans. a lanyard. Energy-absorbing lanyards will reduce the to be more inclined towards safety than the veterans. "The younger crowd will take to it a lot quicker. (Other) workers will take to it; it just takes that habit. This is the new way. This is what we do now, even though I have never had a tool drop — and that's where people need to be convinced," says LeBlanc. The site supervisor plays a big role as well, he says. For example, if the super- visor previously had a tool fall on a job and someone got hurt, he will be more diligent than if he has never had an issue in the past. As a best practice, workers need to understand they should only bring up the tools they need to do their job. Unfortunately, that rarely happens, says Bohmbach. "If they're going up to a height, they're more likely to bring every tool they have on the off chance they might need it, so they don't need to climb back down and get it," says Bohm- bach. "We'd like to recommend them to carry as little on the body as pos- sible to try and limit the amount of weight, because otherwise then you're dealing with other issues like sprains and strains and fatigue." He recommends hoisting items up then transferring them over with various different lanyards either to the workers themselves (if necessary) or static anchor points. This can be done in a bucket, which can then house the extra tools. But the popular plastic buckets seen on many job sites come with safety concerns because they fre- quently fall over, spilling their contents. "I've cited this before on my reports," says LeBlanc. "You see an ironworker with a bucket of bolts up on a beam and if that falls over, anyone in the area is catching bolts coming down 20 feet, which could be deadly." There are many buckets, bags and pouches available on the market with closure systems so items do not fall out. Some even close automatically when turned upside down. Another solution to dropped objects is toe boards, required by many juris- dictions. For example, federal health and safety regulations require a toe board of at least 125 millimetres high "where there is a hazard that tools or other objects may fall onto a person from a platform or other raised area or through a fl oor opening or fl oor hole." Toe boards should be capable of withstanding a force of at least 50 pounds in any downward or out- ward motion. "People really underestimate the value of toe boards. It's such a simple item; it's a no-brainer," says LeBlanc. He recalls an incident back in the 1980s when a worker on a construc- tion site placed his screwdriver and pliers on the edge of the fl oor. He had to leave the area and when he was coming back, another worker acciden- tally hit his tools and they came falling down. The screwdriver hit the worker's hard hat and knocked it off, and the pliers came down immediately after- wards and squared him in the head. "The mezzanine was only at 10 feet and the worker was 6 feet tall, so the tools fell only about 4 feet," says LeBlanc. "The worker was in Niagara General (Hospital) for four months with a concussion that almost killed him. Had there been a toe board there, that accident wouldn't have happened." Nets are another way to catch dropped objects. Green netting that goes over buildings when they are being refaced in cities or areas where there are a lot of pedestrians is the most well-known. There is also netting that is put up within the construction project, such as directly under work being done, to help stop objects from falling on workers underneath. But nets can't be the only solu- tion because objects often don't fall straight down. "It's kind of a myth that the only con- cern is directly below where the work is taking place," says Bohmbach. "The reality is there is a defl ection that can happen. When an object falls from the 20th storey and defl ects off something on the 10th storey, that can fl y hun- dreds of metres away and hit somebody that's not even on the work site." A system where workers check tools in and out can also be effective, which is commonly used in oil and gas. "(It's about) making sure every tool that goes to height comes back down from height so that nothing is left up there that could eventually vibrate off and become a drop hazard," says Bohmbach. Construction workers need to be educated on the dangers of falling objects when working at heights. Safety professionals can increase awareness by putting up posters and making sure supervisors are discuss- ing the issue in tool box talks. A best practice would be a dropped objects prevention guideline that outlines the risk of dropped objects, prevention strategies and responsibilities of man- agers, the health and safety committee and employees. For example, employ- ees need to know they have a duty to report dangerous working conditions, such as a missing toe board. "Besides, if a brick fell off because there was a missing toe board and someone got severely hurt and you knew about it before it happened… it would be hard to live with yourself and know you could have done some- thing about it," says LeBlanc. One of the best ways to get buy-in from workers for dropped object pre- vention is to make sure they think about the people that can be affected by dropped objects. "If my tool is on its way down, I yell 'Watch out.' Am I worried about my own personal safety at that point? Not at all. I'm worried about everyone else's. That's the key. The harness on your body is about you; the harness and lanyards on the tools aren't about you, they're about everybody else," says Caldwell. "That cuts the whining out immediately. This makes you part of the safety equation." among larger construction companies and are not widespread in the indus- try yet, says LeBlanc.
