Approximately 50-300 biopsies are accepted daily in routine pathology laboratories. Samples of these tissues and / or organs are fixed with ready-to-use 10% formaldehyde chemical and then tissue samples are converted to permanent paraffin blocks by following the subsequent tissue stages. These jobs and transactions are quite long and labor intensive activities. Formaldehyde is the basic chemical in fixation and can be easily inhaled and its vapors are considered toxic by WHO and OSHA. For this reason, it is compulsory for the employees to use this chemical carefully and to control the use of the chemical by the current legislation. For this reason, in the regulation no. In line with the mentioned regulation, 20 personnel who were exposed to toxic vapor at different times in Medical Pathology Laboratory were measured by using the badge card at the respiratory level for the detection of toxic 10% formaldehyde vapor gas exposure. After the necessary adjustments were made, the readings at the control level with the collar axle at the respiration level were found to be within the acceptable reference range level and the initial measurement values were reduced. The measured values between TWA and TLV-STEL are consistent, the amount of exposure is directly proportional to the duration of exposure, the appropriate working mode, by applying additional air circulation methods and controlled work with short and long-term exposure to the maximum permissible concentration values can be kept under control It is seen that control can be achieved even in formaldehyde studies carried out at high tempo with low cost effective measures.
