Abstract
Background and Objectives: Dissection laboratories should have effective ventilation always. This study aimed to determine the effectiveness of the ventilation system in a dissection labratory.
Materials and Methods: Based on ISO 16000-8 using tracer gas decay method, the effectiveness of a ventilation system operating at 4 different modes including 1)exhaust system is “on”, 2) supply system is “on”, 3) both systems are “on”, and 4 both systems are “off” in a dissection lab was evaluated. Tracer gas (SF6) was injected into dissection lab and air sampling was conducted in five zones of the lab. The air samples were then transferred to the laboratory and their concentration was determined. Finally, the Local mean age (LMA) and Room mean age of air (RMA) and the rate of local and general exhaust ventilation were calculated. Ethical issues relatet to human bodies was considered in the research protochol.
Results: Two-way analysis of variances showed that while the LMA and the local rate of ventilation at different ventilating modes had no significant, the effect of ventilating mode on the RMA and general ventilation rate, was significant (P <0.001). One-way ANOVA test showed that the exhaust system had the greatest effect on RMA and general ventilation rate of the room.
Conclusion: According to the results, the ventilation is more effective when the supply and exhaust systems are “on” together considering the toxicity of formaldehyde, in addition to the general exhaust ventilation, the implementation of a local exhaust ventilation system for each mortuary desk is recommended.
