2006 New York Code - Use Of Air Contaminant Detector; Use Of Contaminant Recorder; Recording Of Time, Duration, Concentration And Density Of Air Contaminant.

 
    § 24-165 Use of air contaminant detector; use of contaminant recorder;
  recording   of   time,   duration,  concentration  and  density  of  air
  contaminant.
    (a) Whenever the use of an air contaminant  detector  is  required  by
  this code, the air contaminant detector must automatically cause both an
  audible  signal  sufficiently  loud  to  be  heard by a person of normal
  hearing twenty feet from the detector and a readily visible flashing red
  light upon the emission of an air contaminant of a density which appears
  darker than number one on the standard smoke chart,  or  of  an  opacity
  which  obscures  vision  to  a  degree  greater than smoke of number one
  density on the standard smoke chart.
    (b) The signalling devices of the air contaminant detector shall  also
  be  located at the principal work location of the person supervising the
  equipment.
    (c) If two or more units of equipment are connected to a single  flue,
  one  air contaminant detector may be used if installed to monitor all of
  the units.
    (d) If the light source of a photoelectric  type  of  air  contaminant
  detector  fails  to  operate  properly,  the detector must automatically
  cause an audible signal sufficiently loud to be heard  by  a  person  of
  normal  hearing twenty feet away from the detector and a readily visible
  flashing red light which shall continue to operate until manually reset.
    (e) Whenever the use of an air contaminant  recorder  is  required  by
  this code, the air contaminant recorder must:
    (1) continuously produce a record of the time, duration, concentration
  and density of an air contaminant of a density which appears darker than
  number  one on the standard smoke chart, or of an opacity which obscures
  vision to a degree greater than number one; or
    (2)  continuously  produce  a  record  of  the  time,  duration,   and
  concentration  of  sulfur  dioxide  and  nitrogen  oxides  by volume and
  particulate matter by weight.
    (f) Except as provided in section 24-171 of this code, the record made
  by the air contaminant recorder shall  be  dated  and  retained  on  the
  premises  where  the recorder is located for a period of sixty days from
  the last date appearing on the record.
