Abstract:
The LIGO interferometers are extremely sensitive to optical scattering or absorption losses induced by both particulate and hydrocarbon contamination. In order to minimize the likelihood of contamination of optical surfaces, numerous operational practices have been implemented at the LIGO Observatories. The purpose of this document is to describe the operational practices that have been implemented so that it can serve as a reference for observatory staff and visitors.

Notes and Changes:
Added "Note - it is preferable to set hardware directly onto WELL cleaned stainless steel and optical table surfaces, as opposed to foiling the table first. Clean the metal tables with acetone and then isopropanol. The table should be wiped down before every use."

new glove was added on v8:
Use of the SGPF series latex (class 100) gloves from CT International is approved for LIGO Lab
