The construction industry, globally recognized for its fundamental contributions to infrastructure and urban development, is unfortunately also known for its associated risks. While hazards like falling objects, machinery malfunctions, and structural collapses are often discussed and legislated against, there's a silent and pervasive threat that frequently goes unnoticed: fatigue.
Fatigue, in the simplest terms, is the state of heightened mental and physical exhaustion due to inadequate rest. It might seem trivial when compared to the apparent dangers on a construction site, but its consequences can be catastrophic.
Why is fatigue a concern in construction?
According to the National Safety Council’s recent “” report, 100% of surveyed construction workers had at least one risk factor for on-the-job fatigue, which can cause hazardous jobsite conditions and increase the risk of injury. These risk factors include:
- Physically demanding labor, especially work including repetitive tasks
- Constant communication with fellow crew members about complex tasks
- Extended shifts of 10 hours or more
- Working 50 hours or more in a week
- Shifts at irregular times, including night or early morning work
- Having less than 12 hours to recover between shifts
Of the construction employers participating in the survey, 71% said workers’ lack of sleep affected productivity and 45% responded that worker fatigue was responsible for safety-related incidents.
Consider that fatigue dulls the brain's cognitive abilities. This can lead to impaired decision making. A tired worker may take longer to process information, miss out on crucial details, or make incorrect decisions that could put both them and their colleagues at risk.
Fatigue often leads to a decrease in physical coordination. In fact, fatigue can have similar effects to that of drinking alcohol. Physical tasks require precision, especially in construction where a misstep can lead to severe injuries. Fatigued workers have reduced hand-eye coordination, slower reflexes, and might struggle with tasks they'd usually find straightforward.
There’s also the risk of Microsleeps. Microsleeps are short, involuntary episodes of sleep that last from a fraction of a second up to 10 seconds. A worker experiencing microsleeps might not even be aware of these lapses, but during such a lapse, they're essentially 'asleep on the job', raising the risk of accidents.
Consequences of fatigue in construction
Fatigue has been linked to a significant increase in workplace accidents. The U.S. Occupational Safety and Health Administration (OSHA) has noted that workers who are fatigued are more likely to make errors that can lead to accidents, injuries, and fatalities.
Chronic fatigue can lead to serious health issues, including cardiovascular diseases, diabetes, gastrointestinal problems, depression, and weakened immune systems.
There are economic costs as well. Accidents result in project delays, compensation claims, increased insurance premiums, and potential legal actions. Not to mention, constantly replacing or training new staff due to fatigue-related turnovers can be expensive. As a result, according to the National Safety Council (NSC), the hidden costs associated with poor sleep (worker fatigue) cost the construction industry approximately $1.8 million per year on average.
Factors contributing to fatigue
Fatigue plagues the Construction industry because of the nature of its work. These include:
- Long Working Hours: Construction projects often operate on tight schedules, leading to extended working hours or fewer breaks. It is not uncommon for workers to take on 10+ hour shifts.
- Physically Demanding Tasks: The physical nature of construction work means that workers are expending energy consistently, leading to faster onset of fatigue.
- Environmental Factors: Working under the scorching sun or in cold conditions can exacerbate fatigue. These environmental stressors demand more from the body, speeding up the exhaustion process.
- Inadequate Rest: This isn't just about the number of hours slept. Quality of sleep, frequency of breaks, and opportunities to recuperate after demanding tasks are all essential.
Combatting fatigue: steps toward a safer workplace
It is crucial for construction companies to address fatigue within their workforce because of the significant implications it has on safety, productivity, and overall well-being. By recognizing and addressing fatigue through proper scheduling, adequate breaks, and education on sleep hygiene, construction companies not only ensure the safety of their employees but also enhance productivity and maintain a positive work environment. Here’s actions to consider:
- Education: Workers and supervisors need to be educated about the risks of fatigue. Recognizing the early signs can make a world of difference.
- Regular Breaks: Mandate regular breaks, especially during long shifts or in extreme weather conditions. These breaks can significantly reduce the onset of fatigue.
- Limiting Consecutive Shifts: Ensure that workers aren't scheduled for too many consecutive days without adequate rest. The more extended the continuous working period, the higher the cumulative fatigue.
- Promoting Healthy Sleep Habits: Encourage workers to engage in healthy sleep routines. This might involve providing information about the importance of sleep, tips for getting quality sleep, or even providing resting areas for workers on large sites.
- Monitoring and Feedback: Utilize wearable tech, which can monitor vital signs and alert workers or supervisors if there are signs of extreme fatigue. Feedback mechanisms can also allow workers to communicate their levels of fatigue without fear of repercussions.
To sum up, fatigue is a silent but significant risk in the construction industry. Recognizing it, understanding its implications, and taking proactive measures to counteract its effects are critical for ensuring the safety of construction workers.
As the adage goes, "It's better to be safe than sorry." In the world of construction, these aren't just words; they're a mantra that can save lives.
