1.1 The OHS Act Framework, General Duties of Employers and Employees

1. Statutory Architecture and Constitutional Foundations of the OHS Act

The Occupational Health and Safety Act (Act 85 of 1993), hereafter referred to as the OHS Act, represents the primary statutory pillar governing workplace health and safety in South Africa. Promulgated to replace the prescriptive Machinery and Occupational Safety Act (Act 6 of 1983), the OHS Act marked a decisive transition from state-driven command-and-control inspection toward an internal responsibility system founded on self-regulation, bipartite consultation, and systematic risk management.

At a constitutional level, the OHS Act gives practical effect to Section 24 of the Bill of Rights in the Constitution of the Republic of South Africa (Act 108 of 1996), which guarantees that everyone has the right to an environment that is not harmful to their health or well-being. In the context of the built environment, this constitutional mandate translates into an uncompromising statutory obligation: the physical hazards intrinsic to construction—such as structural collapse, falls from height, plant-pedestrian collisions, and toxic chemical exposure—must be methodically identified, evaluated, and controlled.

2. Core Statutory Definitions under Section 1

To interpret and enforce the Act, the Construction Health and Safety Manager (CHSM) must master the legal definitions set out in Section 1 of the Act. Courts interpret these definitions strictly in criminal and civil proceedings:

• "Workplace": Any premises or place where a person performs work in the course of his employment. In construction, this extends beyond the immediate building footprint to encompass temporary site camps, haul roads, laydown yards, batching plants, fabrication workshops, and mobile work zones.
• "Plant": Includes fixtures, fittings, implements, equipment, tools, and appliances, and anything which is used for any purpose in connection with such plant. This broad definition captures fixed installations like tower cranes and passenger hoists, as well as temporary electrical switchboards and mobile generators.
• "Health and Safety Standard": Any standard, irrespective of whether it has the force of law, relating to health or safety. When the Minister incorporates a standard into regulations under Section 44, it becomes part of those regulations (for example, the Construction Regulations require access scaffolding to comply with the safety standard incorporated for that purpose, which the 2017 guidelines identify as SANS 10085). Non-compliance is then an offence under the regulation concerned.
• "Reasonably Practicable": The central legal test of liability in South African occupational health and safety jurisprudence. Section 1 defines "reasonably practicable" as practicable having regard to:
  1. The severity and scope of the hazard or risk in question;
  2. The state of knowledge reasonably available concerning that hazard or risk and of any means of removing or mitigating it;
  3. The availability and suitability of means to remove or mitigate that hazard or risk; and
  4. The cost of removing or mitigating that hazard or risk in relation to the benefit deriving therefrom.

The four factors are weighed together; cost is never considered in isolation. The Act does not quantify the balance, but an employer will rarely persuade an inspector or a court that a life-threatening hazard could be left uncontrolled because an effective, readily available control was expensive.

3. Section 8: General Duties of Employers to Employees

Section 8(1) articulates the primary statutory benchmark of employer duty:

"Every employer shall provide and maintain, as far as is reasonably practicable, a working environment that is safe and without risk to the health of his employees."

To eliminate ambiguity, Section 8(2) specifies ten non-exhaustive obligations that the employer must execute:

• Section 8(2)(a) — Safe Systems of Work, Plant, and Machinery: The employer must design, provide, and maintain working systems, plant, and machinery that do not endanger workers. In construction, this requires formal Safe Work Procedures (SWPs) for high-risk operations such as deep trench excavations, structural steel erection, and precast concrete placement.
• Section 8(2)(b) — The Statutory Hierarchy of Controls: The Act explicitly mandates that the employer must eliminate or mitigate any hazard or potential hazard to the safety or health of employees before resorting to personal protective equipment (PPE). Issuing hard hats, harnesses, and respirators without first implementing elimination, substitution, or engineering controls constitutes a direct contravention of Section 8(2)(b).
• Section 8(2)(c) — Safe Handling, Storage, and Transport: Comprehensive arrangements must be established to ensure safety in connection with the production, processing, use, handling, storage, or transport of articles or substances, including cement, volatile solvents, fuels, and structural steel bundles.
• Section 8(2)(d) — Hazard Identification and Precautionary Measures: The employer must establish the hazards attached to any work performed, any substance produced, processed, used, handled, stored, or transported, and any plant or machinery used. The employer must determine the necessary precautionary measures and provide the means to implement them.
• Section 8(2)(e) — Information, Instruction, Training, and Supervision: The employer must provide such information, instructions, training, and supervision as may be necessary to ensure the health and safety of employees. Training must be task-specific, comprehensible to workers in languages they understand, and refreshed whenever site conditions or plant alter.
• Section 8(2)(f) — Prohibition of Uncontrolled Work: As far as reasonably practicable, no employee may be permitted to do any work, handle any article or substance, or operate any plant or machinery unless the precautionary measures contemplated in Section 8(2)(b) and (d), or any other prescribed measures, have been taken.
• Section 8(2)(g) & (h) — Compliance and Enforcement: The employer must take all necessary measures to ensure compliance with the Act and must enforce such measures in the interest of health and safety. Passive safety policies are legally insufficient; active, documented disciplinary enforcement of safety standards is required.
• Section 8(2)(i) — Competent Supervision: The employer must ensure that work is performed and plant is used under the general supervision of a person trained to understand the hazards associated with it and who has the authority to ensure that precautionary measures are observed.
• Section 8(2)(j) — Scope of Authority: The employer must cause all employees to be informed regarding the scope of their authority as contemplated in Section 37(1)(b). This matters in prosecutions: an employer that never defined what its employees are authorised to do will struggle to prove that an unlawful act fell outside that scope. (The separate duty to make employees conversant with the hazards of their work and the precautions to be taken sits in Section 13(a).)

4. Section 9: General Duties of Employers to Persons Other than Employees

Section 9 expands the employer's boundary of liability beyond contractual employment relationships:

"(1) Every employer shall conduct his undertaking in such a manner as to ensure, as far as is reasonably practicable, that persons other than those in his employment who may be directly affected by his activities are not thereby exposed to hazards to their health or safety."

In the construction sector, Section 9 imposes significant legal exposure. Construction sites are dynamic, open environments frequently situated adjacent to public roadways, occupied commercial buildings, or residential zones. Third parties protected under Section 9 include:

• Members of the general public: Pedestrians walking adjacent to perimeter hoardings vulnerable to falling materials, dust, or noise;
• Visitors and delivery drivers: Material suppliers dropping bricks, aggregate, or structural steel who enter the site boundary;
• Independent contractors and specialists: Subcontractors, architects, structural engineers, and land surveyors working within the operational footprint;
• Neighboring occupants: Adjacent properties exposed to vibration, undermining of foundations, or toxic fumes from waterproofing operations.

Under Section 9(2), self-employed persons (such as freelance plant operators or specialized trade artisans) carry identical duties toward non-employees.

5. Section 14: General Duties of Employees

The internal responsibility system relies on active employee participation and individual accountability. Section 14 establishes five enforceable statutory duties for every employee at work:

• Section 14(a) — Reasonable Care: Every employee shall take reasonable care for the health and safety of himself and of other persons who may be affected by his acts or omissions. On a construction site, this prohibits horseplay, working at height without tying off, or operating equipment while fatigued.
• Section 14(b) — Duty to Cooperate: Employees must cooperate with the employer or any other person to enable any duty or requirement imposed on the employer by the Act to be performed or complied with.
• Section 14(c) — Obedience to Lawful Orders and Rules: Employees shall carry out any lawful order given to them and obey the health and safety rules and procedures laid down by their employer or by anyone authorized thereto, in the interest of health or safety.
• Section 14(d) — Immediate Reporting of Unsafe Situations: If any situation which is unsafe or unhealthy comes to an employee's attention, they must report it as soon as practicable to the employer or to the health and safety representative for their workplace or section, who must report it to the employer. Many client specifications and site rules add a formal stop-work authority, but that authority comes from the employer's own procedures, not from Section 14.
• Section 14(e) — Mandatory Reporting of Incidents Before Shift End: If an employee is involved in any incident which may affect their health or which has caused an injury to themselves, they must report it to the employer, a person authorised by the employer, or their health and safety representative as soon as practicable but not later than the end of the shift during which the incident occurred. Only where the circumstances made reporting impossible may it be reported as soon as practicable thereafter.

6. Statutory Comparison: Section 8 vs Section 14 Duties

7. Strategic Synthesis for the Construction Health and Safety Manager

For the registered Construction Health and Safety Manager (CHSM), Sections 8, 9, and 14 form the operational bedrock of the site Health and Safety Plan. The CHSM must translate Section 8 into structured engineering controls, rigorous method statements, and verified competency matrices. Crucially, the CHSM must advise the Construction Manager (appointed under Construction Regulation 8(1)) that safety cannot be delegated downward through PPE checklists alone. By embedding Section 14 reporting into daily site culture through Daily Safety Task Instructions (DSTIs) and toolbox talks, the CHSM establishes an auditable defense showing that all reasonably practicable steps were taken to protect both the workforce and the public.
