These are the protective engineering controls and systems available in the laboratories. Included is information on restrictions, special precautions or procedures, preventative maintenance schedules and other information relevant to safe operation in the laboratory. If any of these devices are found inoperable, or improperly working, contact Physical Plant Services by telephone at 534-2930. The ventilation system is a 'one-pass' system.
Air is supplied by diffusers in the laboratory with exhaust provided by fume hoods.
The laboratory is maintained a negative pressure relative to the public areas such as hallways to prevent spread of contaminants or accidental releases. There is no recirculation of exhausted air. Laboratory Fume Hoods Fume hoods are to be used for containment of all work with volatile hazardous compounds, hazardous dusts, gases and other materials that may constitute an airborne exposure hazard unless other effective control measures are available. Work shall be conducted at least 6 inches back from the front face of the hood. Storage in the hood shall be kept to a minimum practical level.
