Design, Procurement Specifications

The company has set safety specifications for new machines, equipment manufacturers need to meet the specifications, the labor safety office will conduct safety matters review, if there is any discrepancy, it needs to be improved, before procurement.

Installation Requirements

• Move in:Equipment manufacturers/installers, in accordance with the company's safety regulations.
• Equipment Assembly:According to the implementation of the contractor management measures, the authority and responsibility department shall conduct inspections before, during and after installation to ensure compliance with various safety requirements

Safety Inspection

According to the safety specifications of the new machine, the labor safety room and the equipment department jointly carry out safety inspection, and when there are non-conformities, the equipment manufacturer is required to improve within a time limit, and the machine can be handed over for acceptance only after the re-inspection is passed.

Operation Safety Management

• When the machine is running, personnel must wear corresponding personal protective equipment according to SOP.
• All safety interlocks and detection instruments must be tested and recorded regularly.
• Implement Lock Out & Tag Out: Equipment must be marked in repair and maintenance, and the power source switch/valve should be locked with a lock to block and shut off the power source to ensure operational safety.

• Safety Inspection:Irregular on-site safety inspections are conducted by the labor safety office, supervisors at all levels of the factory and occupational safety offices.

Replacement and Scrapping of Machine Equipment

• Replacement and scrapping:the machine is scrapped, the stop is posted to be disposed of, and the relevant electricity, chemicals and other supply and waste pipelines are blocked and locked.
• Equipment disassembly:Before the equipment is disassembled, it is confirmed that the water, electricity, gas and waste have been blocked, and the dismantler shall carry out the dismantling operation in accordance with the contractor's management measures.
• Move out:The scrapped equipment is handed over to the contractor with a qualified license and implemented in accordance with the relevant regulations of the company.

Chemical Management

In order to strengthen the safety management of chemical operations in the factory area, Unimicron has formulated the "Chemical Management of standard" to regulate the safety standards of each factory's chemicals from purchase, discharge, handling, disposal, use, storage, labeling and chemical distribution system.

Control Mechanisms


Chemical Risk

• Unimicron checks to identify all chemicals used, comparing the "Priority Management Chemicals (Announcement 1,148 in 2021)" and "Regulated Chemicals (Announcement 23 in 2021)" announced by the government according to the law. The facilities report to the government annually.
     - In 2021, no use any "regulated chemicals".
     - In 2021, there are 139 kinds of "priority management chemicals" in the chemical composition, and the amount of operation will be reported according to the law.
• All chemicals stored on-line are limited to one-day usage.
• All barrels/tank chemicals are stored in secondary containers (such as breakwaters, liquid trays, etc.), and set at 110% of their capacity to prevent chemical leakage or spillage.
• Set up emergency showers and related first aid and emergency decontamination supplies (such as Diphoterine, etc.).

Tanker Filling
and Unloading

• Set up the electric pump with independent power control. When encountering abnormal conditions, the interlock device can be activated to cut off the power supply.
• The inlet boxes are set up by zones according to the hazard characteristics of chemicals, and each inlet is set up with an independent box.

• No use combination locks and universal locks/keys to open the inlet box. The responsible unit shall control the unlocking/locking in person.
• Require suppliers to implement safety management such as wheel blocks and personal protective equipment.
• Set up liquid level monitoring alarm and interlock mechanism.
• Set up sump to avoid chemical spillage.
• Install monitor connection monitoring to ensure the safety of chemical loading/unloading operations.

Chemical Distribution System in manufacture for new facility

• An automatic drug supply system is set up in the manufacturing area, and volatile chemicals are designed with sealed and full cover cabinets to avoid employee contact and reduce accidents. Such as liquid dumping, musculoskeletal or splashing when colleagues carry or add chemical.
• The cabinet is designed with independent air intake and exhaust devices to ensure ambient air quality.
• The electric control switch is designed with a leakage trip to prevent the risk of electric shock for employees.
• According to the acid/alkaline properties of chemicals, store them in partitions or layers to reduce the risk of chemical reaction.
• The automatic supply chemical system uses passive reception. Supply chemicals when the equipment side independently calls the medicine/stop signal, reducing the risk of leakage. The supplied chemical pipeline material uses CPVC+PFA double-layer casing throughout the process to reduce the risk of leakage. For the inner layer pipe made of PFA material, the construction method adopts the seamless method.
• Other fool-proofing mechanisms: Barcode comparison before feeding, chemical feed pressure detection, timeout alert, liquid level detection, weight detection, empty barrel warning, secondary container (including leak detection), cabinet fixing to prevent earthquakes and emergency stop button.

Workplace Monitoring

• In order to ensure the work safety of employees, we implement the workplace monitoring plan every six months once in accordance with laws and regulations.

Health examination of employees

• Regularly provide employees with general health examination and specific health examination, and provide reports to employees.

Personal protective equipment

• In accordance with international standards or national CNS inspection standards, the review specifications and standards for various types of personal protective equipment are formulated. Evaluate comfort and suitability of use for personal protective equipment items.
• Specifications for the type and quantity of personal protective equipment that must be prepared for various workplaces.
• Strengthen publicity and audit the use of PPE from time to time to ensure implementation.

Detection Alert

Organization Chart

Emergency Response Flow

There are three stages in Fire, Explosion, Chemical Leakage Emergency Response Operations, please see below for general introduction.

• The Zero Stage (Notification Response):Call, report and respond through the accident notification process when people discover abnormal conditions or the activation of fire detectors.
• The First Stage (Instant Search Response): When the disaster occurs in one area, and the unit of abnormal area (including firefighting team) and the competent authority are called and notified by the witness to conduct timely search and initial rescue.

• The Second Stage (Plant-Level Response): When the disaster spreads from one area to other areas, the unit of abnormal area and the competent authority are unable to control the condition. The plant commander conducts the initiation of emergency response team and takes evacuation action. If the emergency response team cannot effectively control the disaster condition, while the fire brigade is arriving at the scene, the plant commander directly transfers the authority to external unit and assist in providing relevant information.


Each plant has established an Emergency Response Team (ERT), to effectively improve the responders’ on-site search, emergency response, fire-fighting equipment suit and self-contained breathing apparatus (SCBA) wearing, the use of fire hose nozzles, and the response, decision-making and dispatching capabilities. Both plant commander and ERT must finish the relevant professional training courses.

• Standardization on emergency response equipment and fulfillment of regular inspection.
• Establish Emergency Response Team and take refresher training.
• Comprehensively enhance the disaster searching and rescue capabilities.
• Strengthen the emergency decision-making competency of commanders.

Emergency Drill

• Emergency Response Drill::The company implements the self-guard fire protection grouping in accordance with national regulations and the company's emergency response operations, and conducts the emergency response evacuation and drills biannually, including disaster scenario simulation, enhancement of logistics support capabilities, the wearing familiarity of emergency response equipment.
• Emergency Evacuation::To evacuate people who are not the emergency response team to a safe place in the shortest time, this could avoid being affected in case of disaster extension and even influence the rescue. When people move to the assembly point, the number of personnel must be verified and ensure all internal/ external personnel must be at the safe place.
