Summary of worker health, safety, and working environment management practices

Area	Management practices	Details
Working process and environment	Process automation	•Minimizing human exposure time to chemicals
	Sealing and isolation of dust-generating processes	•Minimizing the size of the opening as much as possible •Installing a scattering preventing apparatus such as a hopper
	General and local ventilation installation	• Ensuring a suitable local ventilation in working area - installing in the following order: hood (closing type if possible); duct; air cleaning device; blower; exhaust vents - maintaining the velocity control of local exhaust based on the Safety and Health Regulation (No. 429) •Installing a general ventilation for negative pressure maintenance if having a difficulty in installing a local ventilation
	Work environment monitoring	•Collecting and analyzing the samples in working area to check the standard excess (8-hour TWAs)
	Protective equipment wearing	•Checking mask fitting, suitability, and certification
	Separate storage of combustible materials	•Avoiding ignition sources
Health monitoring	Medical diagnosis	•Performing before and after work including an occasional examination •Needing differentiation from other similar diseases
Health and safety education	Regular education based on the MSDS and technical instruction	•Understanding material toxicity and physiochemical properties, standard operation knowhow, correct use of equipment and device, and emergency treatment
