POM workshop ventilation configuration
Fenómeno del problema
The formaldehyde odor in the POM workshop sometimes exceeds the standard, and relying only on opening windows for ventilation gives unstable results
Análisis de la causa
POM processing continuously releases trace amounts of formaldehyde, and natural ventilation fluctuates greatly due to weather and layout; only local exhaust at the machine can stably control the exposure concentration within the 0.75ppm limit
Solución
①Configure local exhaust hoods at the machines; ②regularly test and record the workshop formaldehyde concentration; ③strengthen protection under high-release conditions (barrel cleaning); after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
POM workshop ventilation is an engineering control problem; local exhaust plus regular testing keeps occupational exposure stably within the limit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
