Lesson 5 : Public Buildings and Design Process
Prevent Occupational Injuries and Illnesses
Provide Designs that Eliminate or Reduce Hazards in the Work Place to Prevent Mishaps
- Consider work practices, employee physical requirements, and eliminating confined spaces when designing buildings and processes.
- Design for safe replacement and modifications of equipment to reduce the risk of injury to operations and maintenance staff.
- Provide proper ventilation under all circumstances, and allow for natural lighting where possible.
- Mitigate noise hazards from equipment and processes.
- Designate safe locations for installation of RF equipment such as antennas on rooftop penthouses. Prevent Falls from Heights
- Provide guardrails and barriers that will prevent falls from heights in both interior and exterior spaces.
Prevent Slips, Trips, and Falls
- Provide designs in accordance with good practice as well as applicable building, fire, safety, and health codes and regulations.
- Conduct preliminary hazard analyses and design reviews to eliminate or mitigate hazards in the work place.
- Use registered design professionals and accredited safety professionals to ensure compliance with safety standards and codes.
- Provide engineering controls in place rather than rely on personal protective equipment or administrative work procedures to prevent mishaps.
- Integrate safety mechanisms, such as built-in anchors or tie-off points, into the building design, especially for large mechanical systems.
- Design a means for safely cleaning and maintaining interior spaces and building exteriors.
- Provide for receiving, storing, and handling of materials, such as combustibles, cleaning products, office supplies, and perishables.
Ensure Electrical Safety
- Provide interior and exterior floor surfaces that do not pose slip or trip hazards.
- Select exterior walking surface materials that are not susceptible to changes in elevation as a result of freeze/thaw cycles.
- Provide adequate illumination, both natural and artificial, for all interior and exterior areas
- Comply with all regulatory and statutory requirements such as the National Disabilities Act and National building Code.
Eliminate Exposure to Hazardous Materials
- Ensure compliance with the National Electrical Code (NEC)
- Provide adequate space for maintenance, repair, and expansion in electrical rooms and closets.
- Evaluate all areas for proper electrical safety measures.
- Consider response of emergency personnel in cases of fires and natural disasters.
- Label all electrical control panels and circuits.
- Install non-conductive flooring at service locations for high voltage equipment.
- Specify high-visibility colors for high voltage ducts and conduits.
Provide Good Indoor Air Quality and Adequate Ventilation
- Consider experts advise in all phases of the project to include planning, design, construction, and maintenance for hazardous building materials and substances
- Consider occupants safety in designing ventilation and drainage systems.
- Provide adequate space for hazardous materials storage compartments and segregate hazardous materials to avoid incompatibility.
- Substitute high hazardous products with those of lower toxicity/physical properties.
- Consider ventilation systems that will be above the minimum standards.
- Recognize and provide specially designed industrial ventilation for all industrial processes to remove potential contaminants from the breathing zone.
- Design separate ventilation systems for industrial and hazardous areas within a building.
- Consider the use of carbon monoxide (CO) monitoring equipment if there are CO sources, such as fuel-burning equipment or garages, in the building.
- Specify materials and furnishings that are low emitters of indoor air contaminants such as volatile organic compounds (VOCs). See Green Products.
- Consider the indoor relative humidity in the design of the ventilation system.
- Avoid interior insulation of ductwork.
- Locate outside air intakes to minimize entrainment of exhaust fumes and other odors. (e.g., vehicle exhaust, grass cutting and ground maintenance activities, industrial pollutant sources, cooling tower blow-offs, and sewage ejector pits).
- Ensure the integrity of the building envelope, including caulks and seals, to preclude water intrusion that may contribute to mold growth.
- Prevent return air plenums/systems from entraining air from unintended spaces.
- Provide air barriers at interior walls between thermally different spaces to prevent mold and mildew
