In Chile, December 8 is a national holiday called “Inmaculada Concepcion (Immaculate Conception)”. As the day is followed by Saturday (Dec. 9) and Sunday (Dec.10) this year, we have three consecutive holidays, however, at the Array Operation Site (AOS), workers are sacrificing their holidays, and installing pipes for the fire extinguishing equipment inside the building . The picture shows the plumbing work of a sprinkler on the second floor. In addition to this, a gas extinguishing system will be installed.
