Exact Extract — Safety Operation Requirements for Digital Power Products (PDF page 9, training slide 8)

Personal safety has the highest priority. The operators are primary owners for safety operations. Safety is based on operator qualification, PPE protection, professional tools, and operation standardization.

Additional Extract — Onsite EHS Management: Temporary Power Consumption Cases (PDF page 36, training slide 35): Electricians must have electrician certificates. At least two electricians are required onsite. One is responsible for operation and the other for supervision and recording. Electricians must wear qualified PPE. Check the grounding and leakage protection of the equipment.

Technical Deep Dive:

Environment, Health, and Safety (EHS) management focuses on preventing accidents, protecting personnel, and ensuring that construction and maintenance activities are performed safely.

Option B is correct because evaluating the general work efficiency of newly onboarded personnel is a productivity or personnel performance activity rather than a defined operational EHS risk-control measure.

Personnel performance assessments may support broader organizational management, but they are distinct from the immediate controls required to manage workplace hazards.

Option A represents an essential EHS responsibility. Supervisors must identify and control risks associated with electrical work, lifting operations, work at heights, battery handling, and other hazardous construction activities.

Option C is an important preventive control. Personnel conducting regulated or high-risk activities must possess the qualifications and certifications required by applicable regulations and Huawei ' s service requirements.

Option D is also a fundamental safety measure. Supervisors must verify that personnel wear appropriate protective equipment based on their assigned activities and exposure risks.

Examples include insulated gloves and footwear during electrical work, safety harnesses during work at heights, and suitable eye protection during drilling or cutting.

Effective EHS management prioritizes hazard prevention, procedural compliance, and the protection of people and equipment.

Final verification: B.

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

Obtain project information. Obtain project information and identify quality risks.

Develop quality plans. Analyze the key items of the project and develop the quality management plan.

Check qualifications. Check whether the certification of the delivery partner company and the special operation qualification certificates of the installation personnel are within the validity period.

Conduct technical and safety disclosure. Participate in technical and safety disclosure, and supervise the supervision engineer to complete technical and safety disclosure to construction personnel, project team leader, customer/EPC and other related personnel before construction entry.

Technical Deep Dive:

The construction preparation phase establishes the operational, technical, and quality assurance conditions necessary for controlled project execution.

Option A is correct because all four activities belong to the preparation stage in Huawei ' s SQA operation standard process.

Preparing for entry involves obtaining project information, understanding the delivery scope, identifying site conditions, and examining potential quality and safety risks.

Quality planning establishes project-specific objectives, critical control points, inspection requirements, and responsibilities. The SQA coordinates relevant business departments to identify risks and implement preventive measures.

Qualification verification ensures that service partners, installation engineers, and personnel conducting specialized operations possess the required valid certifications.

Technical and safety disclosure ensures that construction personnel and project stakeholders understand equipment installation requirements, operating procedures, safety precautions, and preventive measures before construction begins.

The supervision engineer is responsible for conducting the required disclosure, while the SQA supervises its completion and checks the corresponding documentation.

These activities reduce the probability of construction defects, unauthorized work, safety incidents, and subsequent project delays.

The preparation phase is therefore not limited to administrative arrangements. It establishes the controls required for quality assurance throughout subsequent construction activities.

Final verification: A.

Exact Extract — Case 2: Water Enters the Device in the Open-Air Storage Environment (PDF page 266, training slide 21)

Install batteries in a dry, clean, and ventilated environment that is free from sources of strong infrared radiation, organic solvents, and corrosive gases. Do not expose the ESMs to sunlight or water and keep them far away from sources of ignition.

Technical Deep Dive:

Appropriate lithium battery storage conditions are critical to preserving battery reliability, preventing degradation, and controlling fire and electrical safety risks.

Option A is correct because the statement matches Huawei ' s prescribed battery storage precautions.

A dry environment reduces the risk of moisture penetration, corrosion, insulation degradation, and electrical faults.

Clean storage conditions minimize contamination from dust, metallic particles, and other foreign materials.

Adequate ventilation supports environmental control and reduces the accumulation of hazardous substances if abnormal battery behavior occurs.

Protection from direct sunlight and strong infrared radiation prevents unnecessary heat exposure, which can accelerate battery aging and increase thermal stress.

Organic solvents and corrosive gases may damage enclosures, electrical contacts, seals, and other components.

Separation from ignition sources is particularly important because batteries can release combustible gases under certain failure conditions.

The training material also identifies a storage temperature range of 0–40°C, with 20–30°C recommended, and relative humidity not exceeding 95% for the illustrated lithium battery storage case.

Actual storage limits must always follow the applicable battery product documentation.

Final verification: A.

Exact Extract — Prevent Proliferation, and Reduce Losses, Develop Emergency Plans, and Conduct Regular Drills (PDF page 273, training slide 28)

Make the customer/EPC/construction party/fire department be familiar with the product emergency items, check the adequacy, suitability, and effectiveness of the emergency plan, and check whether the departments and individuals involved in the plan are clear about their responsibilities, familiar with the emergency plan procedures, and emergency response capabilities.

Technical Deep Dive:

Emergency drills are conducted to determine whether emergency response arrangements can effectively control incidents and protect personnel, facilities, and the surrounding environment.

The training identifies three principal characteristics for evaluation: adequacy, suitability, and effectiveness.

Option A is correct. Sufficiency corresponds to adequacy. The emergency plan must provide sufficient resources, procedures, personnel, equipment, and organizational arrangements to respond to foreseeable emergencies.

Option B is correct. Suitability evaluates whether the emergency procedures and resources are appropriate for the actual operational environment and potential incident scenarios.

Option D is correct in the intended terminology. Validity is being used to represent the effectiveness of the emergency plan—whether its procedures can produce the required response outcomes under relevant conditions.

Option C is incorrect. Necessity is not one of the three emergency-plan characteristics specifically identified for evaluation in the training.

For energy-storage installations, emergency drills may evaluate personnel evacuation, emergency notification, equipment shutdown, firefighting coordination, incident isolation, and management of potential thermal-runaway conditions.

SQA personnel should supervise the implementation of the drill, verify that participating stakeholders understand their responsibilities, and ensure that weaknesses are documented and corrected.

Terminology qualification: Huawei uses effectiveness, whereas the answer option uses validity. These terms are not universally interchangeable in formal management-system terminology, so D reflects the intended examination mapping rather than an exact wording match.

Final verification: A, B, D.
