Conflict-Free Minerals Statement

Dear Customer:

PEAK is committed to providing our customers with products that are conflict-free and we are committed to investigating the source of such metals in our supply chain to ensure that Au,Ta, W,Co, Sn and other such metals are not mined by anarcho-corps or illegal groups from mines in the DRC and surrounding countries or obtained through illegal smuggling. PEAK is committed to establishing a complete conflict minerals policy, management system and investigation framework that is consistent with relevant laws and regulations, requiring suppliers to conduct source tracing and responsible mineral due diligence on minerals used in products they purchase, and to share due diligence information with customers to ensure that supply chain policies are consistent with the requirements of the guidelines and to gradually improve supply chain transparency and supply chain governance. If conflict minerals are used, they will be immediately reported to our customers and corresponding supporting materials and subsequent rectification plans will be provided according to customer requirements.

DRC and its neighboring countries include: Democratic Republic of Congo (DRC), Republic of Congo (ROC), Central African Republic (CAR), South Sudan (SOUTH SUDAN), Zambia (ZAMBIA), Angola (ANGOLA), Rwanda (RWANDA), Uganda (UGANDA), Burundi (BURUND), Tanzania ( TANZANIA).

Employees or their representatives shall be able to communicate and share suggestions and opinions openly with management regarding the work environment and management practices without fear of discrimination, retaliation, threats or harassment.

  1. Health and Safety

In addition to minimizing work-related injuries and illnesses, establishing a safe and healthy work environment can improve the quality of products and services, facilitate production, improve employee retention and boost employee morale. Suppliers should also understand that ongoing employee engagement and education is critical to identifying and addressing health and safety issues in the workplace.

The health and safety standards are

2.1 Occupational Safety

Potential safety hazards (e.g., electrical and other energy, fire, vehicle, and fall hazards) that employees may encounter should be controlled through proper design, engineering and management controls, preventive maintenance and safe work processes, and ongoing safety training. If hazards cannot be effectively controlled by the above means, employees should be provided with appropriate, well-maintained personal protective equipment and educational materials about the risks that may result from the hazards described above. Employees should be encouraged to raise safety concerns.

2.2 Emergency Preparedness

Emergency situations and emergencies should be identified and evaluated and their impact minimized through the implementation of emergency response programs and procedures, including: emergency reporting, employee notification and evacuation procedures, employee training and drills, appropriate fire detection and suppression equipment, adequate egress facilities, and recovery plans. Such plans and procedures should minimize hazards to persons, the environment, and property.

2.3 Workplace Injuries and Illnesses

Procedures and systems should be in place to prevent, manage, track, and report occupational injuries and illnesses, including provisions to: encourage employees to report them; classify and record cases of occupational injuries and illnesses; provide necessary medical care; investigate cases and take corrective action to eliminate the effects; and assist employees in returning to work.

2.4 Industrial Hygiene

The effects of chemical, biological and physical agents on employees should be identified, evaluated and controlled. Engineering or management techniques must be used to control overexposure to hazards. When these methods cannot be used to effectively control hazards, the health of employees must be protected through appropriate personal protective equipment programs.

2.5 Intense Physical Work

The effects on employees of performing physically demanding work, including manual handling of materials and repetitive heavy lifting, prolonged standing, and highly repetitive or forceful assembly work, should be identified, evaluated, and controlled.
