Exact Extract — A Fire Accident in an Energy Storage Plant: Water Is Considered to Be a Preferred Agent for Suppressing Lithium-Ion Batteries (PDF page 274, training slide 29)

Water is considered to be a preferred agent for suppressing lithium-ion batteries; Water has strong cooling capacity, easy to obtain, easy to transport to the fire site. Water fire fighting is widely used in putting out fire in scenarios of energy storage and electric vehicles.

Technical Deep Dive:

Lithium-ion battery fires present substantial challenges because thermal runaway can produce sustained heat generation, combustible gases, and propagation between adjacent cells or battery modules.

A critical requirement in suppressing lithium-ion battery thermal runaway is effective heat removal.

Option C is correct. Water has high specific heat capacity, making it effective for absorbing and removing thermal energy. When appropriately applied by trained emergency responders using an approved emergency response procedure, water can cool affected batteries, reduce heat transfer to adjacent cells, and help prevent propagation or reignition.

The alternative agents have limitations:

Foam: May suppress certain external combustible-material fires but does not necessarily provide sufficient cooling to stop internal battery thermal runaway.

Heptafluoropropane: Primarily suppresses flames through physical and chemical mechanisms. It does not inherently provide sustained cooling of overheated battery cells.

Carbon dioxide: Can suppress flames by reducing the local oxygen concentration, but it has limited capacity for sustained battery cooling and does not reliably stop ongoing thermal runaway.

Huawei ' s energy-storage fire-handling guidance emphasizes personnel evacuation, emergency notification, electrical isolation where safely possible, and continuous monitoring.

An important distinction is that water must not be indiscriminately applied to energized high-voltage electrical equipment. Firefighting methods must be approved for the specific installation and used under incident-command procedures. Untrained personnel must not attempt to extinguish an ESS fire.

Final verification: Water is the preferred agent among the listed options.

Exact Extract — Safety Colors and Signs: Understand the Meanings Before Site Visits (PDF page 164, training slide 23)

Safety colors and signs are the most basic elements at work sites. Colors and shapes together convey specific meanings.

Safety signs are composed of safety colors, geometric shapes, and symbols. There are four categories of safety signs: prohibition, warning, mandatory action, and information.

Technical Deep Dive:

Safety colors and signs form a standardized visual communication system that helps personnel recognize hazards, understand restrictions, and identify required protective actions.

Huawei ' s engineering safety requirements use color, geometric shape, and symbols together to communicate safety-related information.

The principal safety colors are:

Red: Prohibition, stop commands, and identification of fire-related equipment.

Yellow: Warnings about potential hazards.

Blue: Mandatory actions that personnel must perform.

Green: Safe conditions, emergency information, and safety-related guidance.

Geometric shapes reinforce the intended message.

Prohibition signs typically use a circular symbol with a red border and diagonal line. Warning signs commonly use yellow triangles. Mandatory action signs generally use blue circles, while emergency and safe-condition signs often use green rectangular or square backgrounds.

These elements reduce dependence on lengthy written instructions and can improve recognition across multilingual construction environments.

For Huawei SQA personnel, inspecting the placement, visibility, and appropriateness of safety signs is an important component of site safety assessment.

For example, areas involving high-voltage electrical equipment, hoisting operations, restricted access, or chemical exposure must display appropriate signs according to applicable regulations and project safety requirements.

Effective safety signage complements, rather than replaces, engineering controls, physical barriers, protective equipment, and personnel training.

Final verification: A.

Exact Extract — Precautions for Battery Recycling (PDF page 200, training slide 59)

Dispose of waste batteries in accordance with local laws and regulations. Do not dispose of batteries as household waste. Improper disposal of batteries may result in environmental pollution or an explosion.

If a battery leaks or is damaged, contact technical support or a battery recycling company for disposal.

Technical Deep Dive:

Waste energy-storage batteries require controlled collection, transportation, recycling, and disposal because they contain potentially hazardous materials and may retain significant electrical energy after removal from service.

Lithium-ion batteries commonly used in Huawei Digital Power energy-storage solutions contain electrochemical cells, electrolyte, metallic conductors, and other components that require appropriate end-of-life management.

Improper disposal creates several major risks.

Electrical and fire hazards: Discarded batteries can retain sufficient energy to initiate short circuits if terminals contact conductive materials. Mechanical damage, crushing, or exposure to excessive temperatures can initiate thermal runaway, potentially resulting in fire or explosion.

Environmental hazards: Damaged battery cells may release electrolyte or other substances that can contaminate the surrounding environment. Recycling through authorized facilities enables appropriate handling and recovery of valuable materials.

Transportation risks: Damaged, defective, or end-of-life lithium batteries may be subject to dangerous-goods transport requirements. Their classification, packaging, marking, documentation, and transport conditions must follow applicable local and international regulations.

For SQA personnel, compliance includes verifying that waste batteries are segregated, appropriately stored, and transferred to authorized recycling or waste-management organizations.

Damaged or leaking batteries require additional precautions, including preventing further mechanical damage and monitoring for abnormal heating, smoke, or electrolyte leakage.

Disposal through ordinary municipal household-waste channels is therefore prohibited.

Final verification: The statement is false.

Exact Extract — Adaptation to SQA Operation Standard Process (PDF page 252, training slide 7)

Check the installation environment, including the installation position, foundation conditions, installation space, and warehousing conditions. If the requirements are not met, propose rectification and report the issue to the project owner.

Participate in the entry acceptance of equipment and materials, focus on the key points of unloading and handling, and ensure that the received equipment meets the installation requirements.

Technical Deep Dive:

Huawei ' s standard project delivery framework separates activities into preparation, construction, and completion phases. Each phase contains defined quality control and verification requirements.

Option A is correct. Device positioning is included in the construction phase. Equipment must be moved into its intended location according to approved engineering drawings, foundation conditions, clearance requirements, and handling procedures.

Option B is correct. Environmental checks are performed as part of construction-stage controls. The SQA must verify that installation and warehousing conditions satisfy the relevant product requirements before equipment is installed or placed into service.

Option C is incorrect when the phases are interpreted strictly. Technical and safety disclosure is classified under the preparation phase. It must be completed before construction entry, even though the disclosed requirements govern subsequent construction work.

Option D is correct. Onsite equipment installation is a principal construction-phase activity. It includes installing devices according to approved specifications and controlling installation quality, safety, and protection of finished products.

The distinction between preparation and construction is important for SQA process compliance. Technical disclosures, qualification checks, and quality planning establish the prerequisites for safe construction. Equipment positioning, installation, construction process monitoring, and quality inspections follow during execution.

Answer-key correction: The question-bank explanation groups all four activities into construction. The Huawei standard process on PDF pages 251–252 explicitly places technical and safety disclosure under Preparation, while environmental checks, device positioning, and onsite installation fall under Construction.

Final verification: A, B, and D are the correct selections when applying the training material ' s formal phase classification.

Exact Extract — Service SQA Professional Skill Requirements (PDF page 122, training slide 15)

Capability of safety and quality planning

1. Identify gaps and weaknesses in safety and quality work based on historical safety and quality performance and business development requirements.

2. Organize business departments to carry out safety and quality planning based on gaps and weaknesses.

Additional Extract — Quality Planning Definition (PDF page 126, training slide 19): Quality planning is the process of identifying and developing quality objectives for projects and products, as well as the techniques, processes, tools, key measures, etc., required to achieve these objectives and to ensure that the end result meets customer requirements.

Technical Deep Dive:

Quality planning is a collaborative management process designed to establish project objectives, identify potential risks, determine required controls, and ensure that customer requirements are incorporated into project execution.

Option A is incorrect because the Project Director (PD) holds primary responsibility for overall project quality, while the SQA is the direct owner of partner service quality and coordinates professional quality planning activities.

Option B is correct. It accurately describes the formal definition of quality planning, including objectives, processes, tools, measurements, and customer requirements.

Option C is incorrect. Quality planning must not be completed independently by the SQA. It requires coordination with business departments, project management, construction supervisors, technical personnel, and other stakeholders.

Option D is correct. Effective planning establishes requirements in advance and helps the project team prepare preventive measures before quality or safety problems arise.

Huawei ' s planning methodology includes analyzing the current situation, defining project objectives, specifying key quality activities, producing the quality plan, monitoring implementation, and updating the plan during subsequent phases.

The central objective is to prevent problems through coordinated preparation rather than relying on corrective measures after defects occur.

Final verification: A and C.

Exact Extract — 8 Prohibitions (PDF page 22, training slide 21)

2. Do not touch or operate third-party equipment such as batteries and PDFs.

3. Do not enter the construction area without wearing safety helmets, insulated shoes, or protective clothing.

5. Do not enter the accident scene without confirming safety.

6. Do not perform risky operations by a single person.

Technical Deep Dive:

Huawei ' s eight EHS prohibitions establish mandatory behavioral restrictions intended to prevent serious incidents during installation, commissioning, and maintenance activities.

Option A is correct. High-risk operations must not be performed by a single person where the applicable safety procedures require supervision, a second operator, or emergency assistance.

For example, certain electrical operations require one qualified individual to perform the work while another supervises and records the activity.

Option B is correct. Personnel must not touch or operate third-party equipment without the appropriate authorization and approved procedures. Interfering with customer-owned batteries, power distribution frames, or other electrical infrastructure can introduce serious safety and operational risks.

Option C is correct. Entering an accident scene before confirming that the environment is safe can expose personnel to live electrical conductors, fire, toxic gases, unstable equipment, or other uncontrolled hazards.

Accident response must follow the approved emergency procedure, and unsafe areas must remain restricted until appropriately assessed.

Option D is incorrect because it describes compliant protective behavior, not a prohibited activity.

Wearing safety helmets, suitable insulated footwear, and protective clothing is required where the relevant hazards and site rules demand that equipment.

The prohibition is against entering or operating without the required protection.

Final verification: A, B, and C correspond directly to Huawei ' s EHS prohibitions.

Exact Extract — Safety Operation Requirements 7/7: Electrolyte Contact Prevention (PDF page 190, training slide 49)

If you come into direct contact with the battery electrolyte, do as follows:

Inhalation: Evacuate from contaminated areas, get fresh air immediately, and seek medical attention immediately.

Eye contact: Immediately wash your eyes with water for at least 15 minutes, do not rub your eyes, and seek medical attention immediately.

Skin contact: Wash the affected areas immediately with soap and water, and seek medical attention immediately.

Intake: Seek medical attention immediately.

Technical Deep Dive:

Battery electrolyte exposure presents a significant occupational health hazard because electrolyte components may be irritating, corrosive, or toxic, depending on the battery chemistry.

Huawei ' s safety requirements establish immediate response measures for four principal exposure routes.

Option A is correct. Eye exposure requires immediate irrigation with water for at least 15 minutes. Rubbing the eyes may aggravate tissue damage, so it must be avoided. Emergency medical assessment is essential.

Option B is correct. Accidental ingestion requires immediate professional medical attention. Personnel must not attempt to induce vomiting or administer an unapproved neutralizing substance. Subsequent treatment depends on the electrolyte ' s chemical composition and safety data sheet.

Option C is correct. Skin exposure requires prompt washing with soap and water and medical evaluation. Contaminated clothing should be removed safely to prevent continuing contact with the substance.

Option D is correct. Inhalation exposure requires immediate movement away from the contaminated environment into fresh air, followed by appropriate medical assessment.

For lithium-ion batteries, electrolyte decomposition may also produce hazardous gases during overheating or thermal runaway. Emergency responders must therefore consider respiratory protection and atmospheric hazards.

The applicable Safety Data Sheet (SDS), emergency response procedures, and site-specific chemical safety requirements should govern subsequent treatment and cleanup.

Untrained personnel must not attempt to handle damaged batteries or enter an area containing suspected hazardous gases.

Final verification: A, B, C, and D are explicitly supported.

Exact Extract — Service Consistency Value Proposition (PDF page 217, training slide 13)

Enable service partners to build standard service processes, improve team service capabilities, and use efficient operation tools to provide customers with high-quality and well-regarded services, build customers ' consistent experience, and improve customer satisfaction.

Technical Deep Dive:

Service capability improvement and service standard consistency are closely connected elements of Huawei Digital Power ' s service management framework.

Option B is correct because improving technical skills alone does not guarantee consistent service delivery. Service partners must also implement standardized processes, verify compliance with applicable requirements, and monitor service quality.

Huawei ' s service consistency approach aims to ensure that customers receive predictable service quality regardless of the individual engineer, service partner, or project location.

Standardized service delivery includes defined operational procedures, technical specifications, inspection requirements, documentation templates, and acceptance criteria.

For example, two engineers installing the same Digital Power product should follow equivalent installation standards and produce the required quality verification records.

Without consistent standards, different engineers may apply different torque values, inspection practices, safety precautions, or commissioning procedures, resulting in inconsistent outcomes.

Service capability development therefore requires both personnel competency improvement and verification of operational standardization.

Digital service platforms, structured inspections, and standardized documentation help establish traceability and reduce variability.

For SQA personnel, monitoring service consistency includes evaluating qualifications, process compliance, installation quality, customer feedback, and corrective-action effectiveness.

Final verification: B. The statement contradicts Huawei ' s service consistency value proposition.
