GENERIC LABORATORY FEATURES (Change # 10 9/1/2005) The generic concept, as utilized at Yale School of Medicine, had its genesis in two types of construction and renovation projects. First, were the relatively small projects that, prior to the late 1980’s, were custom designed laboratories. These laboratories reflected the idiosyncrasies of the individual researcher as opposed to the research itself. When the space was reassigned another, often major, renovation was required to respect the idiosyncrasies of the newly assigned investigator. With relatively long reassignment and recycle times, renovation of laboratories for these reasons was not necessarily inappropriate. As cycle times reduced, the costs of these types of renovations became prohibitive. Second, the Boyer Center for Molecular Medicine (BCMM) was designed without assignments. This was consciously done in order to minimize some of the idiosyncratic responses but also to recognize that during the life of a project from inception to occupancy there might be changes in assignment. That building carried a very substantial retrofit component to modify the labs after assignment. The retrofit was done after the building was finished. In studying both of these, Facilities Planning instituted a program of generic design that would reflect the needs of wet bench scientists and allow for appropriate specificity within a fairly structured framework. Analyses were done of benchwork widths, aisle widths, equipment locations, and lighting relative to benches and electrical and gas utilities. A casework design was standardized using standard components that reflected the typical wet bench at the School. The result was a laboratory layout, use of materials, and designation of utilities with a high degree of predetermined specificity. Minor adjustments for location of knee spaces and size and type of drawer and door units provided virtually 99+% of the cases. This is in part due to the lack of chemistry laboratories. Cupsinks were eliminated both as a practical matter and as a request from the New Haven Water Authority and Sewer Authority. Since 1990 there have only been two statements of dissatisfaction. One of those was withdrawn once the logic was expressed. The concept has been used on every laboratory renovation since 1990 both in small one-room renovations to the recent major renovation of SHM B-Wing, First Floor. The concept, in particular with larger rather than smaller laboratory modules, allows for considerable flexibility in assignment without modification to the laboratories. The larger allocations of space for fixed equipment permits flexibility in changes based on the nature of the research and available technology. A recent modification allows for dedicated rooms for hot work to conform to NRC regulations while not inhibiting activities in the remainder of the lab. Top of the Document

LABORATORY ACCESSIBILITY STANDARDS Yale School of Medicine has received a Handicap Waiver from the provisions of Section 1108.12, Laboratory Stations of the BOCA National Building Code/1996 portion of the 1999 State Building Code. using the alternative described in the pages that follow. This waiver was approved by the State of Connecticut Office of Protection and Advocacy for Persons with Disabilities and the Department of Public Safety, Division of Fire, Emergency & Building Services, Office of the State Building Inspector with support from the New Haven Office of Building Inspection & Enforcement. The alternative described in the following pages allows for an adaptable approach to meet the needs of a person with a physical disability in laboratories. It is key that all adaptable elements of the lab workstation be identified and labeled clearly on the construction documents for compliance with the waiver. Top of the Document

Suggestions for an Adaptable Approach to Laboratory Accessibility

November 22, 2000 Please note that a workstation can include 1) four to six linear feet of laboratory bench (including bench utilities), 2) a carrel, 3) access to a sink and, in some cases only, 4) access to a fume hood. The requirement for accessibility in both the current and former code is the provision of required accessibility per Lab Group (see attached for full definition of Lab Group). 1. To provide accessibility at the laboratory bench, the carrel would become the laboratory bench for the person with a physical disability. When the carrel is part of the bench it is provided with a chemical resistant laminate top. Alternatively, when the carrel is not part of the bench, an area of bench countertop would be provided with a seam to allow for easy removal of an area of countertop. Alternate heights can be provided by simply exchanging different height casework that supports the countertop. In this way an appropriate height bench space would easily be installed in the event a person with a physical disability is employed in the lab. 2. To provide accessibility at the carrel an additional carrel would be assigned to a person with a physical disability. Alternatively, when a carrel is not available an area of bench countertop with a seam will be provided to allow for easy removal of an area of countertop. An alternate height can be provided for a carrel by simply exchanging different height casework that supports the countertop. In this way an appropriate height carrel would be installed in the event a person with a physical disability is employed in the lab. 3. To provide accessibility at the laboratory sink we propose the provision of an area of bench countertop adjacent to the sink with a seam to allow for easy removal of an area of countertop. Alternate heights can be provided by simply exchanging different height casework that supports the countertop. In this way we would install an appropriate height hand-washing sink in the event a person with a physical disability is employed in the lab. The adjacency of the seamed countertop (and future location of the accessible sink) to the existing sink would allow for easy tie-ins to the existing piping. This arrangement would work when the sink is located at the end of a bench or when it is located against a wall. (Condition 1 and 2 in SK-1) 4. To provide accessibility at the fume hood we propose that an area be designated within the laboratories of a particular Lab Group for the location of a future accessible fume hood to be installed in the event that a person with a physical disability is employed in the laboratory. Alternatively, if an area is not designated an existing fume hood could easily be changed out to an accessible fume hood in the event a person with a physical disability is employed in the lab.

Yale University Central Campus and School of Medicine

Lab Group Definition

At the Central Campus (includes Science Hill) and at the School of Medicine, the organizational unit of research is the academic department or section. Each department or section consists of a group of faculty members who are carrying out research within a thematically related area. At the Central Campus (includes science Hill) departments include areas such as chemistry, biology or physics. At the School of Medicine departments include areas related to basic biomedical science (e.g., genetics, cell biology, physiology) or clinical science (e.g., dermatology, neurology, orthopedic surgery). The Chair of the department, or the Chief of the section, has responsibility for the implementation of Central Campus (includes Science Hill) or Medical School policies. He/she also has authority for the assignment of space and other resources. Thus, the faculty and staff of each department or section function as an interdependent laboratory group, who work together and share both equipment and facilities. It should be noted that in the renovation of laboratories in existing buildings, the relationship of the renovated laboratory to the laboratory group and the constraints of the existing building configuration should be considered in defining accessibility requirements.

XOMAT POLICY

This policy is established to reduce the number of flooding incidents caused directly or indirectly by XOMAT film processor equipment. Drains clogged from XOMATS cause substantial flooding damage to occupants on the floor below. All new and existing installations will have the following: Ventilation: Prior to installation of a processor, BS&O will retain the services of a licensed air-balancing contractor to determine if the ventilation rates are adequate. If the report shows the room to be deficient, HVAC modifications will be made prior to the installation of the film processing equipment, with charging instructions from the department. Floors and Drains: Floors will be sealed with the Medinteck welded seam solid vinyl flashcove system or equal and pitched from the door, walls and cabinets to the drain. A four inch drain will be installed and be located close to, but not obstructed by, the film processor. Locks: The locksets used for the rooms with film processing equipment will allow both the user and BS&O access. This is to enable BS&O to secure the area if there is a flood. Equipment Connections: All Flexible hoses used to connect utilities to the film processor will be of a non-burst reinforced material. A stainless steel or aluminum drain pan will be installed under the processor. The drain from this pan will be piped into the floor drain. Drain Service: The services of a commercial firm (Parker X-Ray or approved equal) will be contracted to assure that all the drains from the processor are regularly cleaned. This contract will be held by the department and will include as a minimum: Cleaning the drain that is located after the developer on a monthly basis (or more often if needed). Cleaning process should include: application of granular "fotex" powder for 15 to 20 minutes and then flushing with water through the drain to dissolve the developer hardening clogs in the drain trap. A method of documentation will be developed. The costs to comply with this policy are the responsibility of the department using the Xomat film processing equipment Top of the Document

BIOLOGICAL SAFETY CABINET INSTALLATION The minimum clearance required from the top of the biological safety cabinet (BSC) to the ceiling is ten inches. This will allow for proper exhaust airflow and repair of the BSC when necessary. A minimum three-inch clearance on the side and 1.5 inch clearance in the back are recommended. BSCs must be placed away from doors as well as ventilation supply and exhaust vents to reduce air currents around the BSC. The electrical outlet for a BSC must be a 20 amp dedicated circuit that is readily accessible for service and electrical safety testing. If a BSC is to be connected to a gas supply a flexible connector will be used. The connector must comply with the Standard for Connectors for Moveable Appliances, ANSI Z21.69. A quick-disconnect device is not recommended. An accessible manual shutoff valve must be installed at the outlet of the gas supply piping system upstream of the connector, as required by ANSI Z21.69. If a BSC is to be connected to vacuum, an appropriate flexible connection should be used.

Evaluation of Proposed Biological Safety Cabinet Locations

Biological safety cabinets can be located easily in most facilities. They should be kept away from drafts, convection currents, diffusers, and traffic paths. For further information or assistance, contact the Office of Environmental Health and Safety (7-2125). Top of the Document

Controls Policy: Off-hours set back policy The system should incorporate two independent volume controllers in a “typical” (+760 SF) lab * : 1. The light switch determines the amount of general exhaust 800 CFM (on position) versus 250 CFM (off position) 2. The hood sash position determines the amount of hood exhaust 920 CFM

(in use position) versus 300 CFM (in not used position) Each of these controllers acts independently creating four possible airflow combinations ranging from 4.6 AC/hr to 14.3 AC/hr (see table below). Twist timers are required to allow for research to be done in a darkened room. A sign will be mounted at the light switch stating, “Use twist timer if laboratory is occupied with lights out”. Twist timer will override the light switch controller to maintain full occupancy CFM flow. *CFM and SF stated here are examples only EXAMPLE:

LOW VOLTAGE SYSTEM STANDARDS

The following are the Yale School of Medicine's Standards for the installation of low voltage wiring and fiber: Cables routed in corridors and public areas shall be run in j-hooks, cable trays, or conduit as determined by Yale. 1. Cable trays shall be rung type and shall be installed extending from the floor Telecom closet through the

entire length of the corridor. Nominal tray size shall be 6 inch wide by 3 inch deep, depending on space density. Trays shall connect directly into the floor Telecom closet, or be connected with sleeves. In cases where there is no room for cable trays, conduit(s) should be installed. Sizes of conduit, associated junction boxes and routing shall be specified by the project engineer in agreement with the BS&O Department and Yale University telecom design standards. Cable trays could also support the needs of other low voltage and fiber systems such as security and building controls. (In the areas where conduit is used, each system would require dedicated conduits.) Conduits to be marked at 25 foot intervals to clearly identify the contained system.

2. A two-inch diameter sleeve shall be installed above each corridor door to connect the cable tray or conduit

system to the spaces served. Connections to trays located on opposite side of the corridor require either conduit or wiring, neatly bundled and secured, crossing the corridor. Within the user space, cables above dropped ceiling would be routed using split rings. Conduit would be used only in situations where data cables (not fiber) require electro-magnetic shielding from lamp ballasts, motors, power cables, or transformers.

3. Drops for phone and data, from the above ceiling system described in 2 above shall be conduit installed

within walls down to wall mounted outlet boxes or wiremold. The top of the conduit shall be open and accessible above the drop ceiling level.

4. Use of flexible conduit (to house low voltage wiring) will be allowed ONLY for short distances to a maximum

of 6 feet. 5. Each Low Voltage System (Telecommunications, Security and Controls) shall install all wiring and cabling in

a neat and orderly manner. These wires and cables shall be bundled together and clearly marked and identified at 25 intervals (or at key junction points) using plastic cable tags. wires and cables added to existing cable tray-runs shall be placed adjacent to existing cables of the same system and tie-wrapped to the bundle to maintain a neat and orderly tray arrangement.

6. color codes for identifying systems are as follows: security systems ............................................ blue building controls ............................................. green telecom/data .................................................. yellow fire alarms ...................................................... red Fire alarm systems shall remain installed in dedicated conduit.

EXTERIOR LIGHTING CRITERIA

PEDESTRIAN LIGHTING: 1. Light Source: Metal Halide or Incandescent. 2. Illumination Levels: 0.50 Minimum Horizontal Footcandles on walks in heavy volume areas to: 0.35 Minimum Horizontal Footcandles on walks in low volume areas. Uniformity Ratio: 3:1* (maximum to average). 3. Luminaire Posts: At roadways ...................... 12 ft. Courtyards, etc. ................ 10 ft. 4. Illumination Patterns: Asymmetrical for walks (NEMA Type III). Symmetrical for open areas (NEMA Type V). Typical installation for walks: 175 watt Metal Halide luminaries mounted on 10 foot posts with an asymmetrical illumination patter; 60 foot spacing between luminaries with the posts located 3 feet from the walk for 0.50 foot-candles midway between luminaries. Distance between luminaries can be increased to 70 feet with 12 foot posts. (Distances are approximate and are dependent upon several factors, such as obstructions, shadows, light absorption and/or reflection of surrounding objects, buildings, foliage, etc.) PARKING AREAS: High pressure sodium lighting is to be used. *A uniformity ratio up to 6:1 may be acceptable for specific lighting applications.

REQUIREMENTS FOR REDUNDANCY AND STANDBY ELECTRIC POWER AS APPLIED TO BUILDING SYSTEMS SERVING ANIMAL ROOMS. The following requirements apply to new or major renovations to building systems serving animal rooms. Redundancy shall be provided within the following system designations: Exhaust Air: Two separately driven exhaust air fans shall be installed. Each fan shall have the capacity to

provide 100% of the exhaust air requirements of the space. The electric power connected to each fan motor shall be fed through a dedicated circuit. Redundant ductwork is not required.

Control Air: Two separately driven control air compressors shall be installed. Each compressor shall have the

capacity to provide 100% of the control air requirements of the space. The electric power connected to each compressor motor shall be fed through a dedicated circuit. Redundant compressed air tanks are not required.

Steam Condensate: Two separately driven condensate pumps shall be installed. The electric power connected to

each pump motor shall be fed through a dedicated circuit. Redundant condensate receivers are not required.

Liquefied Animal Waste: In locations where animal waste drains to a sump, duplex sewage ejector pumps shall

be installed. The electric power connected to each pump motor shall be fed through a dedicated circuit. Redundant sump tanks are not required.

Redundancy to be determined at time of design: Supply air: If redundant supply air fans are a design requirement, each fan shall be separately driven and have

the capacity to provide 100% of the supply air requirements of the space. The fans may be mounted within the same air handler or in separate air handlers as space permits. The electric power connected to each fan motor shall be fed through a dedicated circuit. Redundant ductwork is not required.

Standby Electric Power shall be provided to the following building system equipment: Exhaust air fan motors. HVAC control panels (all). Steam condensate pumps. Liquefied animal waste sump pumps. Standby Electric Power to be determined at time of design for the following equipment: Supply air fan motors. The transfer from normal electric power to standby electric power on a system and component level shall be a manual operation. Top of the Document
