There’s nothing new about what job-site safety boils down to. It’s the simultaneous application of procedures, products, and employee participation. The most up-to-date equipment isn’t worth the dollars you’ve invested if it doesn’t address the hazards your employees are exposed to. And if employees don’t follow procedures, it doesn’t matter how great their equipment is.

“What you should be looking for,” says Evelyn Bennett, vice president of sales and marketing at William Frick & Co., specialists in safety information products, “is a systematic approach that carries through, multiple times and in multiple ways.”

“It’s important to remember that construction sites change from day to day,” says Tim Reilly, market specialist for construction and utilities at North Safety Products, which markets personal protective gear, “which means everyone must be constantly aware of their surroundings and what’s going on. The one thing you really want to be aware of is people who are not on the machines, which is why employers are going to bright-colored hardhats and reflective stripping on hardhats and vests. The problems develop when employees decide they don’t need their hardhats because there’s nothing immediate going on overhead. Or they don’t need them in the cab of a vehicle. But the minute they step out, things can change.”

Eye protection figures among the top safety priorities on construction sites.

Reilly’s top gear priorities for construction sites include head, eye, and face protection, as well as fall protection and hearing protection. “Fall protection is a huge issue. Between 650 and 720 people die annually because of falls. Barrels or other kinds of obstructions are OK to keep people out of an area, but employees who have to work near a hole in the ground should have a horizontal lifeline and harness. This won’t prevent a fall, but it will protect the individual if the unexpected happens.

“We find if they’re busting up concrete, people will put on a face shield, for example, but then they won’t wear glasses underneath. Or they’ll put glasses on, but they won’t be safety glasses—I’d say it’s fifty-fifty they’re not safety glasses. Most people don’t wear adequate hearing protection on job sites. You’ll see people who have a pair of plugs in their ears, but they’re sticking so far out they’re basically just laying there. The fact is that if they’re worn correctly, foam earplugs that expand are as good as a muff and can offer a higher level of protection. People should be aware if they’re wearing a muff and then put glasses on, they’ll break the seal. The same with a guy smoking or chewing. If your jaw is constantly moving, you’re constantly breaking the seal. And nine times out of 10, when a person puts a muff on, they just sort of lay it over their ears. If it’s loose, it’s not going to do the job.” Reilly encourages employers to keep current with regulations such as ANSI 107-2004 Class 2 High Visibility Apparel, which applies to workers on federal-aid highways, effective November 24, 2008, and ANSI Z359.1-1992, which restructured fall protection as of October 2007.

Critical to job-site safety is awareness of backing vehicles. But the news from this arena is old news: Backup alarms have become so ubiquitous that they’re often ignored. According to University of California Berkeley’s Institute of Transportation Studies, reports from the National Institute of Occupational Safety and Health (NIOSH) indicate over half of work-zone fatalities involve workers on foot who are killed by construction vehicles moving in reverse. One problem is that employees tune out backup alarms; a second is the alarms themselves, which can be difficult to differentiate and pinpoint to a particular vehicle.

“The problem with normal narrowband beeper alarms is the sound is ambiguous,” says Jack Woginrich, national sales manager for Brigade Electronics Inc., which offers a broadband backup alarm. “This causes confusion about where the sound is coming from. And because they are so common, neither workers nor the general public associate typical narrowband backup alarms with an immediate threat. So while the alarms are designed to improve safety, they can actually contribute to danger by causing confusion and stress.”

The multifrequency range of the bbs-tek alarm from Brigade Electronics spans from 400 Hz to more than 10,000 Hz, eliminating the irritation of “alarm clock” narrowband alarms. The “hish-hish” sound is not only different from conventional alarms (one construction employee described it as sounding like “a sick duck”): Its particular strength is that it is directional, which means you can easily identify the vehicle it’s attached to. It also dissipates quickly, which helps reduce noise pollution. And while the decibel level can be the same as other alarms, the frequency is lower, which is much less of a nuisance to the human ear.

“You get immune to regular backup alarms,” says Steve Wagoner, who as general manager at CTE Sand and Gravel in Tecumseh, MI, equipped all the company’s loaders and haul trucks with Brigade’s broadband alarm. “If you’re beside a vehicle or machine that’s equipped with it, you don't hear it very well,” says Wagoner. “But if you’re behind it, it will blow your ears off.” The Mine Safety and Health Administration has certified the bbs-tek as meeting all MSHA requirements for 30 CFR 56.14132, which covers horns and backup alarms for service equipment, and the Society of Automotive Engineers (SAE) has recognized Brigade Electronics for noise management innovation. The cities of New York and Seattle have given the product a push with noise restrictions on construction work. Seattle’s noise variance requires trucks and mobile plants to have either a spotter or a broadband backup alarm for nighttime operations. And New York City’s Department of Environmental Protection’s list of alarms that meet its new noise regulations includes the Brigade bbs-tek as the only alarm that covers any job site in the city, including such sensitive areas as schools, hospitals, parks, and places of worship.
