Construction Occupational Health Guide

Construction Industry Occupational Health Guide

In South Africa, the construction industry adheres to stringent regulations to safeguard the health and safety of workers on-site. Governed under the Occupational Health and Safety (OHS) Act (No. 85 of 1993), these measures provide a robust legal framework for preventing injuries and occupational diseases. The Act mandates employers to maintain safe working environments, conduct hazard identification, and implement risk assessments, ensuring compliance across all construction activities.

The Construction Regulations, last updated in 2014, further refine these duties by outlining specific responsibilities for employers, contractors, and workers. These include appointing competent safety agents, drafting health and safety plans, conducting baseline risk assessments, and ensuring medical surveillance tailored to the specific risks associated with each role. Provisions for managing high-risk tasks such as fall protection, scaffolding, and hazardous chemical handling are clearly defined, emphasising the importance of proactive safety practices.

The Occupational Health and Safety Amendment Bill strengthens accountability in alignment with international standards. It enhances penalties for non-compliance, reinforcing the collective responsibility of stakeholders, from clients to subcontractors, to maintain a health-conscious and compliant work environment. These regulations and industry-specific standards, such as the SANS codes, ensure the standardisation of practices across critical areas, including electrical work and hazardous material management.

This guide provides an in-depth analysis of health and safety in job roles within the Construction Industry. It includes occupational health risks, recommended medical surveillance, biological monitoring, and essential Critical Personal Protective Equipment (PPE) for each construction role. The guide is structured according to the typical phases of a construction project.

Medical Surveillance Key Terms and Categories

Occupational Health Risks

Occupational health risks refer to potential hazards in the workplace that can lead to injury, illness, or long-term health issues. These risks are specific to the tasks performed and the work environment and may include chemical exposure, physical strain, noise, vibration, and other environmental hazards.

Medical Surveillance

Medical Surveillance is a systematic approach to monitoring workers' health, identifying occupational health risks early and ensuring compliance with safety standards. Different medical examinations are tailored to specific job profiles and the inherent risks associated with each role. To assist with a medical assessment, the Employer must complete an Annexure 3 form listing the employee's job risks and submit it along with the Employee/ Patient to the medical examination. Below are detailed descriptions of key types of medical examinations.
