The only instruments to which definite locations in the various buildings can be assigned are the area-monitoring instruments, classification c above. The locations selected for these instruments have been arbitrarily chosen, and actual survey when the reactor is in operation may result in these locations being changed.

Methods and iastmments that are used to monitor phosgene content ia air are well developed and have been reviewed (46—48). One detection iastmment is a porous tape that measures the concentration of phosgene ia air ia quantities as small as 6 ppb (49). Fourier transform ir spectrometry techniques have been developed to permit line and area monitoring ia the area around phosgene plants (50). 

A variety of instmments are available to analyze carbon monoxide in gas streams from 1 ppm to 90%. One group of analyzers determines the concentration of carbon monoxide by measuring the intensity of its infrared stretching frequency at 2143 cm . Another group measures the oxidation of carbon monoxide to carbon dioxide electrochemically. Such instmments are generally lightweight and weU suited to appHcations requiring portable analyzers. Many analyzers are equipped with alarms and serve as work area monitors.

Block valves are often controlled on the basis of analyzer results, such as area monitors for detecting solvent leaks, reactor analyzers for detecting runaway reactions (a block valve can be opened to add a reaction inhibitor or to turn on a deluge system), sewer analyzers for detecting high concentrations of contaminants, and vent analyzers to detect high levels of contaminants. 

Upon completion of the one hour agitation the decon mixture will be adjusted to a pH between 10 and 11. Conduct general area monitoring to confirm that the atmospheric concentrations do not exceed the airborne exposure limits (See Sections II and VIII). 

After sealing the head, the exterior of the drum shall be decontaminated and then labeled IAW EPA and DOT regulations. All leaking containers shall be overpacked with vermiculite placed between the interior and exterior containers. Decontaminate and label IAW EPA and DOT regulations. Dispose of the material IAW waste disposal methods provided below. Dispose of material used to decontaminate exterior of drum IAW Federal, state and local regulations. Conduct general area monitoring with an approved monitor (see Section VIII) to confirm that the atmospheric concentrations do not exceed the airborne exposure limit (see Sections II and VIII).

Environmental health and safety Hazardous area monitoring Environmental monitoring compliance... 

Hydrants should be located on the street or roadside of all pipelines or drainage ditches to allow access for the pumper truck. Where large pipelines or drainage ditches may hinder access, access across such obstructions should be provided. Hydrants and manually operated monitors should be located outside of tank dike areas. Monitors capable of remote operation from outside tank dike areas may be located within that area.

Notes Particulate monitoring during unloading freeze dryer area will be considered as level III locations not in use will be monitored during the complete area monitoring once per week R represents hypothetical room numbers. 

Health Physics Laboratory. The health physics laboratory is located at the entrance to the radiation sources controlled area (Figure 2). From this laboratory the access to the radiation sources area is monitored and controlled. The health physics laboratory is equipped with portable beta, gamma, and neutron survey meters of various designs and ranges to facilitate the area monitoring, air monitors for airborne contamination, and anticontamination equipment. It is equipped with monitors and alarms for the area radiation detectors, pool water level indicators, and access doors. It also has ready access to the counting equipment of the radiochemistry laboratory.
