PPS Dust and Workshop
Fenómeno do problema
The PPS processing workshop has an irritating odor, and operators have throat discomfort
Análise das causas
High-temperature PPS melt releases trace amounts of sulfur-containing irritating gas; it accumulates when machine head exhaust is insufficient; workshop ventilation and local exhaust are basic occupational health requirements; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
①Configure local exhaust at the machine head; ②Overall workshop ventilation and air exchange; ③Evacuate personnel and strengthen exhaust during degradation accidents; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PPS workshop gas management cannot be ignored; local exhaust plus overall ventilation is the standard configuration; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
