Aerosol concentration at the discharge point of the hose is adjustable from 0 to 45 mg/m3 (0 to 6 mg/min).Room air would dilute the discharge quickly. The aerosol smoke is odorless and not visible. Proper precautions to avoidover exposure such as good ventilation and limited discharge time are recommended. Do not hold end of hose close to faceduring aerosol discharge.The maximum allowable limit under OSHA (Occupational Safety and Health Administration) regulation in an eight-hourweighted average for oil-based aerosol is 5 mg/m3. The RUDOL TM White Mineral Oil is approved by the FDA (Food andDrug Administration) for use on skin and incidental food contact.To reach the OSHA allowable limit, for example, you need to discharge at the maximum concentration rate (6 mg/min)into a non-ventilated 14x12x10 feet room for a period of about 50 minutes. However, in typical testing, very little aerosolis introduced into the room. The normal time per test is only about 30 seconds at 1/4 of the maximum concentration, farbelow the OSHA safety limit. However, precaution is necessary to avoid situations where exposure can reach above theOSHA limit.THIS INSTRUMENT SHOULD NOT BE USED IN OR NEAR CONCENTRATED OXYGEN ENVIRONMENTS SUCH ASOXYGEN TENTS OR OPERATING ROOMS IN A HOSPITAL.THIS EQUIPMENT OPERATES AT VOLTAGE LEVELS THAT CAN BE HAZARDOUS TO OPERATINGPERSONNEL.The Model 501-B Aerosol Generator-Analyzer for Smoke Detectors operates on a rechargeable 12V Ni-Metal Hydridebattery. This voltage appears at the serial number label and various other points on the chassis. The power of theinstrument should be completely turned off before opening the front panel for filter change or repair. Only qualifiedpersonnel, who are familiar with the location of the voltage and the hazards involved, may open the cabinet with powercircuit energized. When connecting a new battery, make sure to observe correct polarity. Connect the red positive (+)line to the red positive (+) battery terminal and connect the black negative (-) line to the black negative (-) batteryterminal.! |
