    Study Notes

    Safety Regulations

    • OSHA Guidelines: The Occupational Safety and Health Administration (OSHA) sets standards for construction sites to ensure a safe working environment.
    • Hard Hat Areas: Designated areas where hard hats are mandatory to prevent head injuries from falling objects or debris.
    • Fall Protection: Guardrails, safety nets, and personal fall arrest systems are used to prevent falls from heights.
    • Electrical Safety: Lockout/tagout procedures prevent electrical shock and electrocution.
    • Hazard Communication: Workers must be informed about hazardous materials and chemicals on site.

    Construction Materials

    • Common Materials:
      • Concrete: A composite material made from cement, water, and aggregate (sand, gravel, or crushed stone).
      • Steel: Used for structural framing, roofing, and reinforcement.
      • Wood: Used for framing, flooring, and roofing.
    • Sustainable Materials:
      • Recycled Materials: Reused materials reduce waste and conserve natural resources.
      • Low-Carbon Cement: Reduces greenhouse gas emissions during production.
      • Insulation Materials: Improve energy efficiency and reduce environmental impact.
    • Specialty Materials:
      • Glass: Used for windows, doors, and exterior facades.
      • Aluminum: Used for roofing, siding, and structural components.
      • Composite Materials: Combines materials like wood and plastic for durability and sustainability.
