| Heavy grade steel construction. |
Durability for many years of service. |
| Start up warning horn. |
Alerts operator and surrounding personnel of engaged machinery. |
| Automatic shut-off and alarm when drum is full. |
Prevents over filling of drum and jamming of crushing machine. |
| On board air compressor with water condensation filter and automatic water purge. |
Ensures dry air for back purging H.E.P.A. filters. |
| Automatic purging H.E.P.A. filtration system. |
Back purging H.E.P.A. filters with high pressure air ensures unrestricted process airflow and extended H.E.P.A. filter life. |
| Utilizes 85lbs. of activated carbon. |
A safe crushing process requires subatmospheric pressure to contain mercury vapors. Adequate mercury absorption is a critical component in the lamp crushing procedure. |

Integral computer monitors process while signaling automatic functions to be executed. |
ENVIRONMENTAL SURVEY
INTRODUCTION
Limited occupational exposure testing was performed by Donald A. Schambach, Jr. of Evans Environmental & Geosciences (EE&G). The purpose of the survey was to determine the extent of noise and mercury vapor exposure to the workers in association with the Drum-top-lamp-crusher.
A mini-enclosure work station was constructed using polyethylene sheeting supported by an aluminum frame. The work station was approximately 10' x 10' and contained the Drum-top-lamp-crusher. The Drum-top-lamp-crusher process involves individually placing fluorescent lamps in an entry port where the lamps are fed to a crushing device which deposits the material in a 55 gallon drum. When the drum is full, it is sealed and removed from the work area for silica/mercury separation. The Drum-top-lamp-crusher is designed for use by lamp waste generators to eliminate pallatizing (packing) lamps for shipment to recycling centers.
METHODS
Survey Methods:
Industrial noise stress was monitored using the Quest Technologies Micro-15 Noise Dosimeter.
Mercury Vapor samples were collected per NIOSH Method 6009.
Laboratory Methods:
Each sample was sent to Armstrong Forensic Laboratories in Arlington, Texas. Upon arrival at Armstrong Forensic Laboratory, the samples were logged and stored for analysis. Analyses of Mercury samples was performed using Atomic Absorption, Cold Vapor techniques established in NIOSH Method 6009.
SURVEY LIMITATIONS
The objective of this survey was to identify and assess worker exposure to noise and mercury vapor during the use of the Drum-top-lamp-crusher.
The results, conclusions and recommendations contained in this report pertain to conditions which were observed at the time of the survey. By this report, EE&G makes no representation or assumptions as to the nature of past conditions or future occurrences.
This industrial hygiene survey report has been prepared by EE&G in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions. No other warranty, expressed or implied is made. EE&G's interpretations and recommendations are based upon the results of sample collection and analyses, as well as investigative/exploration/surveyed locations and, that such conditions are unknown, may change over time, and have not been considered. EE&G will not be responsible for the interpretation or use by others of data developed pursuant to the compilation of this report.
CONCLUSION AND RECOMMENDATIONS
Mercury Vapor Testing
Two samples were taken on the inside of the mini-enclosure work station and one sample was taken immediately outside the mini-enclosure work station. Three field blanks were included with the three samples taken. All three samples taken indicated mercury vapor levels below the threshold limit value of 0.05 mg/m3.
Noise Dosimetry
Noise levels inside the mini-enclosure work station were below 88.51 decibals. Noise levels outside the mini-enclosure work station were below 92.22 decibals.
