Which of the following is correct about operators undertaking special work (for example, constructors working at heights, electricians, and welders)?

Operators undertaking special work, such as working at heights, electrical work, or welding, are exposed to high-risk environments. To ensure personnel safety and compliance with legal and industry standards, it is mandatory for these operators to complete specific safety technology training, successfully pass a formal appraisal or examination, and obtain a valid work certificate. This three-part requirement ensures that the individual possesses the theoretical knowledge, practical skills, and official authorization to perform the hazardous task safely. Experience alone does not supersede these formal qualification requirements, as standards and technologies evolve.

A. Experience does not exempt an operator from legal and safety mandates for formal training and certification, which ensure up-to-date knowledge.
B. A certificate is the official and legally recognized proof of qualification; simply passing a training appraisal is insufficient for regulated high-risk work.
D. Certification is a critical, non-negotiable requirement for special work. Training without the corresponding official certificate does not authorize an operator to perform the task.

Ltd.

EHS Guidelines for Engineering Delivery Projects. This document outlines the Environment

Health

and Safety (EHS) requirements for all project activities. In sections pertaining to high-risk operations

it consistently mandates that personnel must be qualified and certified. For example

Section 5.3

"Management of Special Operations

" specifies that "Personnel engaged in special operations must receive special safety technical training

pass the examination

and obtain the special operation qualification certificate before they can take up their posts." This directly supports the necessity of training

appraisal

and certification.

2. Huawei Technologies Co.

Ltd.

Subcontractor EHS Management Red Lines. This document establishes absolute safety rules that must not be violated. Red Line No. 5 often states

"Personnel engaged in special operations (e.g.

electricians

welders

riggers

crane operators

scaffolders) must be certified." This reinforces that certification is a mandatory

non-negotiable requirement for performing special work

making options A

B

and D incorrect.
