Eskom and its subsidiaries will conduct business with respect and care for people to ensure that no

operating condition or urgency of service endangers the life of anyone or causes injury or damage

to the environment. Eskom is committed to preventing all work-related injuries. In fulfilling this

commitment to protect people, the environment and property, management will provide and

maintain a safe and healthy work environment, in accordance with industry standards and in

compliance with legislative requirements.

At-risk behaviour leads to incidents. Life-saving Rules are safety rules that have been created to

enforce zero tolerance for serious at-risk behaviours. These rules have been determined in terms

of the consequences of the behaviours they describe, that is, if a particular set of behaviours or

actions has a very high probability of causing disabilities or fatalities when performed.

The Eskom Life-saving Rules complement our existing safety best practices and are safety rules to

be followed at all locations.

The Life-saving Rules apply to all Eskom employees, agents, consultants, and contractors. Visitors

to Eskom should also respect and adhere to these rules as applicable and could be instructed to

leave the Eskom premises with immediate effect should they refuse to do so.

2. Supporting Clauses

3. Document Content

Life-saving Rules are safety rules that, if not adhered to, have the potential to cause serious harm

to people. The consequences of a person knowingly and wilfully violating these rules will result in a

disciplinary process in accordance with the Eskom Disciplinary Code and Procedure.

The objective of this standard is to clarify Eskom’s intention to enforce “ZERO TOLERANCE” with

respect to behaviour resulting in serious risk to an individual at the workplace.

It must be noted that the content of this standard does not detract from the requirements for safe

behaviour for all other work-related activities or other safety requirements, but emphasises the

importance thereof.

3.1.1 Rule 1: open, isolate, test, earth, bond, and/or insulate before

Touch

With the aim to ensure a safe electrical work environment, no person may work/operate on, around

the apparatus is safe to work on;

f) He/she makes the specific electrical environment safe prior to performing the work; and

g) All the appropriate PPE (including face shield and insulated gloves for low voltage work) are

worn.

3.1.2 Rule 2: hook up at heights

Working at height is a significant part of work in Eskom Holdings and is regarded as a high-risk

activity, and as a result all precautions must be taken to prevent incidents while working at height.

Wherever reasonably practicable, preference must be given to the performance of work at ground

level as opposed to work in an elevated position. Where work in an elevated position is necessary,

the requirements in this document shall apply.

No person may work at height where there is a risk of falling unless:

irrespective of when the substance was used.

3.1.5 Rule 5: ensure that you have a permit to work

standards and procedures. Outline the key principles or rules to support the implementation of the

standard statement.

3.2 Consequences of violating a Life-Saving Rule

In terms of general health and safety in Eskom, if any of the Life-saving Rules are violated, it will

be treated as a serious misconduct, and result in a disciplinary process in accordance with the

Eskom Disciplinary Code and Procedure.

It must be highlighted that Eskom takes a ZERO TOLERANCE stance to violation of these rules.

Depending on the circumstances, Eskom reserves the right, where a contractor

manager/supervisor allows the violation of a Life-saving Rule, to suspend the contractor’s activities

while determining an appropriate sanction.

In the light of a contractor employee allegedly violating a Life-saving Rule, the contractor shall

immediately remove the employee from site and initiate the disciplinary process. The contractor

shall investigate any violation of a Life-saving Rule and initiate the disciplinary process within five

(5) working days of the violation. The contractor shall after the disciplinary process furnish Eskom

with a copy of the sanction.

This document is a 'PAYE Questionnaire for Service Contracts' to Eskom. It is a tax classification tool applicable from 1 March 2026 to 28 February 2027. Its purpose is to determine whether a contractor (Individual, Company, Close Corporation, or Trust) is an Independent Contractor, Personal Service Provider, Labour Broker, or Dependent Contractor for Employees' Tax (PAYE) withholding purposes. It consists of two evaluation packs (A for companies/CCs/trusts, B for individuals) with detailed questions and affidavits. The document includes a disclaimer and definitions from the Income Tax Act.

The pack is applicable from 1 March 2026 to 28 February 2027. It is based on tax legislation for the 2026/2027 tax year.

For tax-related queries, the completed pack must be submitted to your Eskom representative for referral to the Eskom Group Tax Department at Megawatt Park. When returning the completed pack, copy Group Tax on email: [email protected].

Returnable Documents: This is a tax classification pack, not a tender submission. The document is a 'Supplier Evaluation Pack' for PAYE determination. You must complete and return the signed summary sheet and signed affidavits to Eskom. When returning the completed pack, copy Group Tax on email: [email protected].

The primary eligibility is related to tax status, not technical capability for the rubber services tender. Key tax classification criteria include: Being a South African tax resident; employing three or more full-time, non-connected employees; not having connected persons render services to Eskom; not receiving >80% of income from Eskom or associated institutions; not performing services mainly at Eskom premises under Eskom's control/supervision; and passing the 'dominant impression' test to demonstrate independent contractor status.

This is not a technical specification document. It is a tax classification tool (PAYE Questionnaire) for service contractors. Its purpose is to establish whether an Individual, Close Corporation, Company, or Trust should be classified as an Independent Contractor, Personal Service Provider, Labour Broker, or Dependent Contractor for tax purposes.

This is not a pricing schedule. It details tax withholding consequences for Labour Brokers: - If a valid IRP30 exemption certificate is provided to Eskom: No Employees' Tax (PAYE) is withheld. An IT3(a) certificate with code 3617 is issued. - If a valid IRP30 certificate is not provided: PAYE will be withheld from payments at individual tax rates until a valid certificate is provided. An IRP5 certificate with code 3617 is issued.

Tax Withholding Implications: - If classified as an Independent Supplier/Contractor and you meet the 3-employee test, no PAYE is withheld (sign Appendix 8). - If classified as a Personal Service Provider or Dependent Contractor, PAYE will be withheld from payments at the prevailing tax rate (sign Appendix 7, codes 3601 or 3616). - For Labour Brokers: if you provide a valid IRP30 exemption certificate, no PAYE is withheld and an IT3(a) with code 3617 is issued. If you do not provide a valid IRP30, PAYE will be withheld until you do.

Tax Compliance Requirements: This pack determines your compliance with the Income Tax Act regarding Employees' Tax (PAYE) withholding. Key requirements include: - You must be a Resident of South Africa (or declare non-resident status). - For exclusion from PAYE: you must employ 3 or more full-time employees engaged in your business who are not Connected Persons. - You must declare if any Connected Person will render services to Eskom. - You must declare if more than 80% of your income is from one client. - You must declare the place of work and level of Eskom control/supervision. Various signed affidavits (Appendices 1-10) are required based on your answers.

This is not tender evaluation criteria. It is a tax status evaluation using a 'Dominant Impression Test' with 11 questions (6(i) to 6(xi)). The test assesses factors like payment terms, Eskom's control over tools/staff, right to subcontract, personal risk for quality, obligation to be present, economic dependence, integration into Eskom's structure, and provision of benefits/equipment. Answers are classified as 'Independent' or 'PSP' (Personal Service Provider)/'Employee'. The result determines if you are classified as an independent contractor or if PAYE must be withheld.

Appendix A – Vessel Rubber lining Specification

To account for various conditions, two options such as rubber lining patch repairs or complete rubber lining

replacement are considered in this document.

Rubber lining inspections shall be carried out by the Contractor and Eskom representative and thereafter

inspection findings shall be documented. Based on the inspection findings, Eskom with recommendations

from the Contractor, will decide upon the suitable rubber lining option (either rubber lining patch repairs or

complete replacement).

Option 1 - Rubber Patch Repairs

Assess the condition of the existing rubber lining through detailed visual inspection and pin-hole detection

testing (no more than 3 kilovolts per mm). Identify and mark-up the defects or the areas requiring the

repairs.

The Contractor shall compile a rubber patch repair procedure and submit to Eskom for approval. As a

minimum, the repair procedure shall include the following:

Pin-hole detection testing on the existing rubber lining.

• Cutting out, stripping and removal of the existing rubber in the marked-up areas as per the above

inspections.

• Surface preparation of the substrate after removal of the existing rubber. For smaller areas to be patch

repaired where abrasive blast cleaning is impractical, the Rubber Liner or Contractor shall propose a

suitable cleaning method. The cleaning method shall be submitted to Eskom for review and approval

before commencement of the work.

• Provision shall be made for mechanical repairs i.e. welding and grinding where necessary before new

rubber patch repairs. The Contractor shall propose substrate repair procedures and submit these to Eskom

for approval.

• Care shall be taken during welding and surface preparation to protect the remaining rubber lining from

any damage such as mechanical damage, welding/grinding sparks, and welding spatter.

• Once the mechanical repairs and surface preparation are completed then conduct rubber lining patch

repair of the affected areas. The total surface area to be rubber lined will be determined by inspection.

Option 2 - Complete Rubber Lining Replacement

After inspection step in option 1 is completed and inspection findings documented; if the damage covers a

large surface area, Eskom with recommendations by the Contractor will decide on complete rubber

replacement.

• The Rubber Liner or Contractor shall remove most of the existing rubber lining by initial removal

techniques such as cutting out, stripping and flapper disc grinding.

• Subsequent surface preparation shall be by means of abrasive blast cleaning method.

• After the old rubber lining is removed and initial surface preparation is completed, a detailed visual

inspection shall be carried out to check for defects of the substrate surface. Where necessary mechanical

repairs i.e. welding and grinding shall be carried out before new rubber is installed. The Contractor shall

propose substrate repair procedures and submit these to Eskom for approval. The procedure shall be

agreed by both parties before commencement of work.

• Corrosion Protection shall only proceed once all mechanical or welding activities on the vessels have

been completed and released in terms of the applicable mechanical repair Quality Control Plan (QCP).

2 Specific Project Requirements
