Overlooked Safety Risks on Construction Sites
Overlooked Safety Risks on Construction Sites Introduction Construction sites have hidden risks and hazards that go unnoticed until they become serious issues or lead to incidents. Beyond visible hazards at these sites, many overlooked dangers pose a serious threat to the worker's health and safety. One such hazard is Noise-Induced Hearing Loss (NIHL), is often underestimated as a hazard but affects almost 14% of construction workers who are exposed to hazardous noise levels for more extended periods. Also, chemical exposure aggravates hearing loss, turning it into a significant threat. Other overlooked hazards are Asbestos & Silica Dust exposure, that cause permanent damage to the lungs of many employees. Hand-Arm Vibration Syndrome (HAVS) occurs in workers with persistent high-vibrational tools. Similarly, Falling Objects & Debris often result in injuries and fatalities due to poor site management. Lastly Poorly Maintained Tools And & Equipment increase the risk of workplace injuries and accidents. These lesser-known hazards should also be addressed and managed adequately at worksites to reduce the long-term health impacts on construction employees. Read on this blog post to understand the causes and risk factors of these overlooked hazards and how we can mitigate them to improve construction workplace safety. 1. Noise-Induced Hearing Loss: The Silent Threat This significant threat is the cause of 14% of occupational hearing loss in construction workers, as reported by the CDC. This issue worsens as 52% of construction workers in noise-exposed worksites do not wear hearing protection. The NIHL affects construction workers more than any other industry, with sub-sectors having even higher rates, such as bridge and highway construction. Hearing loss begins at or above 85 decibels (dB) for extended periods. For better understanding, the chainsaw functions at around 100 dB, and a jackhammer can get to 130 dB. Noise-induced hearing loss develops gradually, making detection difficult until significant damage has occurred. Therefore, implementing solid hearing protection programs is essential to combat this silent threat. Common Sources: All types of loud equipment, such as power tools, jackhammers, and heavy machinery, are sources of NIHL. Symptoms: The following are the most common symptoms of NIHL: Muffled Hearing. Ringing in the Ears (tinnitus). Difficulty understanding speech, especially in noisy environments. How to Prevent NIHL? Hearing loss can be prevented if workers use personal protective Equipment (PPE) such as earmuffs and earplugs. The worksite should implement noise control measures, and employees should undergo regular hearing tests to catch early signs of damage.

Silica Dust & Asbestos: The Silica Dust Hazard Cutting, drilling and grinding the concrete at construction sites generates silica dust, a commonly overlooked hazard. Inhaling silica dust causes scarring and inflammation of the lungs, resulting in silicosis, a form of interstitial lung disease. Shockingly, nearly 2 million U.S. construction workers are exposed to silica each year, increasing their risk of silicosis. Silicosis Symptoms: Early-stage symptoms include difficulty in breathing and coughing. Advanced-stage symptoms include chest pain, weight loss, and fatigue. Complications in silicosis can increase the risk of tuberculosis and lung cancer. Asbestos Exposure: Found in older buildings and structures, this deadly substance also affects the respiratory health of the workers. Prolonged exposure to Asbestos causes mesothelioma, a rare but aggressive and incurable cancer type that manifests in the lungs and abdomen lining. Asbestos Exposure Symptoms: Chest pain. Shortness of breath. Weight Loss. Fatigue. Notably, these symptoms may take decades to appear after initial exposure. How to Prevent the Asbestos Exposure? Implement the following strategies at your workplace to prevent asbestos exposure1. Ensure proper ventilation by allowing good airflow at the work site. Apply dust control measures such as wet cutting & grinding techniques. Mandate respirators when working around asbestos and silica dust. Train the workers to handle hazardous materials safely. When these strategies are implemented effectively, employers can reduce the influence of silica dust and asbestos on workers' health. 3. Hand-Arm Vibration Syndrome (HAVS) Workers who use vibrating tools regularly get affected by Hand-Arm Vibration Syndrome (HAVS), a significant occupational hazard. It causes vascular, neurological and musculoskeletal symptoms that can lead to permanent damage if not addressed promptly. Statistics show that, up to 1 in 10 regular users of vibrating tools develop HAVS. Early intervention is important as HVAS symptoms become permanent. Once fully developed HAVS Causes: Vibrating tools such as jackhammers, chainsaws, drills, and grinders, when used for prolonged periods, cause HAVS. HAVS Symptoms: Following are the Neurological, Vascular & musculoskeletal symptoms of HVAS: Tingling, pain, numbness and inability to discriminate between delicate touch. Following are the vascular symptoms of HVAS: Greying or whitening of fingers (Raynaud's phenomenon) is mainly caused by cold. Following are the musculoskeletal symptoms of HVAS: Weakened muscles. Losing the grip strength in hands and fingers. Pains and aches in arms and hands. The HVAS symptoms take months or even years to develop. They become irreversible if left untreated. How to Prevent HVAS? Use alternative methods such as non-vibrating tools whenever possible. Maintain the Equipment regularly to cut down the vibration levels. Rotate the job among the workers to limit the exposure to vibrations. Encourage employees to wear warm clothing to improve blood circulation. Raising awareness and enforcing preventive measures can significantly reduce the risk of HAVS and its life-altering effects on construction workers. 4. Falling Objects & Debris Falling objects & Debris are another hazard that often cause life-threatening head injuries. Improperly managed debris, unsecured tools, and building materials can become deadly projectiles. Falling Objects Causes: Here are the main causes of falling debris and objects. Strong winds can dislodge loose materials from rooftops and scaffolds. Loosely stacked materials can tip over and hit the workers. Unsecured tools and equipment placed on elevated surfaces can also fall on the workers. Preventive Measures for Falling Debris Implement the following preventive measures at your workplace to prevent falling debris injuries: Instruct all the workers to use hard hats in areas prone to falling Debris. Install toe boards around scaffolding to prevent the tools from slipping. Place nettings or screens above the work areas to seize falling debris. Use lanyards to secure the tools when working at elevations. By implementing these safety measures at your construction site, you can reduce the risk of injuries and ensure safety at the workplace. Broken Tools & Equipment Broken tools and equipment pose serious danger to construction workers. Tools experience wear and tear over time, leading to malfunctions, mechanical failures, and even electrocution. Risks Posed by Broken Tools & Equipment Malfunctioning tools have an increased risk of accidents due to unexpected tool behavior. Faulty wiring and insulation can cause electrocutions. Mechanical tool failures can lead to severe injuries among the workers. Best Safety Practices for Tool Maintenance: Regularly inspect the tools for damage and wear and tear. Promptly fix and replace damaged tools and Equipment. Securely store the tools when not in use. Following these practices will reduce the hazards and risks of poorly maintained tools and Equipment on construction sites. The Final Thoughts Small and overlooked hazards in the construction industry often go unnoticed until it's too late. However, with the help of the right precautions, these risks can be reduced. For example, the primary cause of lung disease among construction workers is silica dust, which can be mitigated with the help of OSHA Silica Awareness Training. This training help workers identify, control and reduce silica-related risks before they cause irreversible damage. Likewise, asbestos is a hidden hazard, especially in older buildings, with persistent exposure causing cancer. Workers can, however, recognize asbestos-related hazards by enrolling in the OSHA Asbestos Awareness Training. Another overlooked hazard is faulty or worn-out tools that can severely injure the worker. Our OSHA Hand and Power Tools Safety Training offers guidelines on safe tool operation and hazard recognition to avert accidents. Lastly, all types of construction-related accidents can be prevented by utilizing the correct PPE. The OSHA Personal Protective Equipment (PPE) Training helps workers to choose the right gear for their job correctly and reduces the likelihood of injuries. Remember that construction hazards are real but with the right training and precautions, they can be prevented.
