Electrical

30.  Shall provide GFI protection to electrical receptacles above counter tops and within 6 feet of sinks. Receptacles that are not readily accessible or receptacles for appliances occupying dedicated space, which are cord-and-plug connected in accordance with NEC Section 400-7A(6-8), are exempted. 

_{NFPA 70, Chapter 2, 210-8} 

31.  The lab should be fitted with an adequate number of electrical outlets, which can accommodate electrical current requirements with an additional 20-40% capacity. 

_{Good Practice per Stanford University}

The lab may have several pieces of equipment, which require large amounts of electrical current. Such items include freezers, biosafety cabinets, centrifuges, and incubators. The room design must take into consideration concerns such as electrical demand prior to occupancy to avoid a potential power failure.

32.  Circuit breakers should be located outside the lab, but not in rated corridors. 

_{Good Practice per Stanford University EH&S}

In the event of an emergency, the laboratory may be unsafe to enter. Hence, the circuit breakers for key electrical appliances should be located outside the lab. ICBO recommends not putting electrical panels in rated corridors.

Plumbing 

33.  Auxiliary valves for gas and vacuum lines should be located outside the lab. 

_{Good Practice per Stanford University EH&S}

In the event of an emergency, the laboratory may be unsafe to enter. Hence, the valves for gas and vacuum lines should be located outside the lab.

34.  Flexible connections should be used for connecting gas and other plumbed utilities to any freestanding device, including but not limited to biosafety cabinets, incubators, and liquid nitrogen freezers. Flexible connections should be appropriate for the pressure requirements and should be constructed of material compatible with the transport gas. A shutoff valve should be located within sight of the connection and clearly marked. 

_{Good Practice per Stanford University EH&S}

Seismic activity may cause gas and other utility connections to break off. A flexible connection will minimize this potential considerably. 

35.  Sink drains traps shall be transparent (e.g., made of glass) and easy to inspect or have drain plugs to facilitate mercury spill control.

_{P.A. Ordinance, 16.09.032(b)(14)}

If mercury-containing products or compounds will not be used, an exemption may be requested in writing to; Stanford University Environmental Quality Manager, Stanford Utilities Department, Mail Code 7270.

36.  Lab waste water lines shall be separate from domestic sewage, and a sampling point shall be installed in an easily accessible location outside the building.

_{P.A. Ordinance, 16.09.060}

The sampling point shall be installed at a location where all building lab wastes are discharged, before the lab waste line connects to the domestic waste line. The sampling point shall be designed so that it is perpendicular to the lab waste line, has a minimum 4 inch diameter, has a cleanout screw on cap and is protected by a christie box. The sampling point should not be located in an area where water from irrigation or flow from stormwater runoff can accumulate.
