Question
Limiting the concentration of which of the following substances protects the health of construction personnel?
A. Biomass
B. Compostable materials
C. vocs
D. CFC refrigerants
Answer
C. vocs
Explanation
vocs are volatile organic compounds that can evaporate from paints, solvents, adhesives, and other building materials. They can cause health problems such as eye irritation, respiratory distress, headaches, and cancer. Limiting the concentration of vocs in the air protects the health of construction personnel by reducing their exposure to these harmful substances.
Limiting the concentration of VOCs protects the health of construction personnel. VOCs are chemicals that easily evaporate at room temperature, releasing harmful vapors into the air. Many construction materials, paints, adhesives, sealants, and cleaning products contain VOCs.
Exposure to VOCs can cause eye, nose and throat irritation, headaches, nausea, and damage to the liver, kidneys and central nervous system. Some VOCs are also suspected or known carcinogens.
By choosing low-VOC and zero-VOC products, using proper ventilation, and following manufacturer instructions, construction teams can minimize VOC levels and protect worker health. LEED and other green building standards set limits on VOC content to maintain good indoor air quality.
The other options are incorrect:
A. Biomass refers to organic matter used as fuel. It does not directly impact worker health.
B. Compostable materials are biodegradable, but not necessarily hazardous to workers.
D. CFC refrigerants deplete the ozone layer. While an environmental concern, they don’t directly affect construction personnel if properly handled.
So in summary, limiting VOC concentrations through careful product selection and site practices is the key to protecting construction worker health and wellness.
