A listing was compiled by NIOSH of all lasers presently in use and their hazard classification according to the scheme to be proposed by OSHA. Through an Interagency Agreement with the United States Army Environmental Hygiene Agency (USAEHA) the following objectives were attempted: to gather technical specifications on all lasers currently in use from the manufacturers' data sheets; to classify the laser from the manufacturers' specifications; and to confirm the manufacturers' data by measuring a small sample of lasers and cross checking the calibration of the manufacturers' instrumentation. Contained in this compilation was the resulting computerized list of almost 2500 models available from over 175 manufacturers and distributors in the laser safety field. It was possible to classify most lasers using the manufacturers' specifications if the user had not modified the laser. The many helium/neon lasers specified as 1.0 milliwatt output power were placed in Class-IIIa, since these lasers originally had an output power exceeding 1.0 milliwatt at the time of manufacture. It was noted that the user of the list should check the specifications available in the manual supplied with the particular laser against the parameters listed in the computer printout.
