Safety Equipment for Handling the 20-kW and 5-kW Arc Lamps

摘要

The 20-kW xenon compact arc lamp used as the energy source for the simu-lated solar system in the 25-ft space simulator has an internal pressure of approxi-mately 4.2 atm (47 psig) at room temperature; and at operating temperature, its pressure increases to approximately 10 atm (132 psig). For this reason, safety equipment must be supplied for the men who work around these lamps. Several tests were conducted on various pieces of protective clothing exposed to the breaking of quartz envelopes identical to those used in the manufacture of com¬pact xenon arc lamps. Quartz envelopes and two Pyrex tubes similar to the lamps were broken at 45 psig. Various articles of protective clothing and different types of materials were exposed to the lamp and then inspected for marks and cuts. Later after much modification the test was repeated with very encouraging results. A verification test of face shield and leather gloves was performed to prove safety with a more direct explosion impact. Other tests were run to evaluate different methods of approach for personnel protection and to establish safety requirements for the 5-kW arc lamp.
