👉 Vendors' fumes refer to the unpleasant odors and chemical vapors that can emanate from various sources, particularly those associated with industrial processes, automotive repairs, and construction sites. These fumes often contain volatile organic compounds (VOCs) like benzene, toluene, and formaldehyde, which are common in products such as solvents, paints, fuels, and adhesives. In enclosed spaces, these chemicals can accumulate, leading to a noxious smell that can be both irritating and harmful if inhaled over prolonged periods. Symptoms may include headaches, dizziness, nausea, and respiratory issues, making it crucial for workers and nearby residents to maintain good ventilation and use protective equipment to mitigate exposure.
