5.0 HEALTH AND SAFETY PRECAUTIONS

To avoid damage to the monitor, ensure that the AC power voltage matches the voltage
indicated on the monitor's model/specifications label located on the rear panel before plugging
the T640 into line power. High voltages are present inside the instrument. Ensure that the power
cord being used can carry the power rating of the instrument (see rear panel label). Note:
• Power connection must have functioning ground connection.
• Do not defeat the ground wire on power plug.
• Turn off instrument power before disconnecting or connecting electrical subassemblies.
• Do not operate with cover off.
Some repair and troubleshooting operations need to be carried out with the monitor open and
running. Use common sense when operating inside a running monitor. Exercise caution to avoid
electrical shocks and electrostatic or mechanical damage to the monitor. Do not drop tools into
the monitor or leave those after your procedures. Do not short or touch electric connections with
metallic tools while operating inside the monitor. For small shelter maintenance, beware of
external elements (i.e., weather conditions).

6.0 INTERFERENCES

There are no known interferences to the collection of PM2.5 and PM10 using this method;
however, surface roughness and other variables do affect sizing algorithms in all light scattering
instruments.

7.0 PERSONNEL QUALIFICATIONS

Personnel who operate instruments used for the ambient monitoring of PM within the State of
Florida are typically selected for their position based on applying for the position and
demonstrating they have the required knowledge, skills, and abilities to perform the essential
elements of the position. Prior to independently operating PM monitoring equipment, personnel
are to be thoroughly trained in these duties. Supervisory/Management staff will then document
they have the required training and will then authorize the employee to perform the operations
outlined in this SOP.
A measure of agreement among individual measurements of the same
property, usually under prescribed similar conditions, expressed generally in
terms of standard deviation.
The act of checking or verifying an instrument against a standard; involves no
adjustment of the instrument.
