TO: Keith Fogg Interoffice Communication FROM: DATE: SUB J: Tom Grumbles May 16, 1985 RECORDKEEPING REQUIREMENTS FOR FIXED POINT MONITORING DATA VISTA To confirm our discussion regarding the applicability of the OSHA Medical and Exposure Records Access Standard to fixed point monitoring, I have attached an opinion from Legal. Basically fixed point data, as we take it and use it, is not generally construed as employee exposure data and does not have to be retained for compliance with the OSHA standard. However, you should check with plant environmental personnel to determine if they have needs for the data. I would recommend that some form of data summary be maintained to be used in the event of litigation. This could be weekly, or whatever is reasonable based on your systems operation. Thomas G. Grumbles Attachment cc: Bob Seymour Bill McClain i VVV 000000933 (Conor'S) hi* R ^ ft, '.t 0 3 Interoffice Communication To Tom Grumbles From Michele Malloy September 27, 1983 Subject APPLICABILITY OF 29 CFR 1910.20 REQUIREMENTS TO FIXED POINT MONITORING DATA Based on our discussions and my understanding of the function and the data collected by these in-plant systems, it would not be subject to the recordkeeping requirements of 29 CFR 1910.20(d) (1) (ii), Employee Access to Medical and Exposure Records. Fixed point monitors can be useful tools in the control, as opposed to the measurement, of employee exposures by indicating the concentration of a chemical in the air at a particular point, at a particular time, detecting leaks, and generally determining the effectiveness of control devices. This informa tion can be useful to trigger alarms or provide early indica tions of increased concentrations. However, personal exposure monitoring remains the significant manner to determine employees1 exposure. The ultimate question is the amount of contaminant to which an employee is actually exposed, not merely the level of contaminant in a certain place at a certain time. "Exposure monitoring" is the monitoring done with the purpose and capability of actually measuring the employee's breathing zone exposure. Therefore, it is my opinion that fixed point monitoring data would not generally be construed as employee exposure records. Counsel CO VVV 000000934
