Logistics Occupational Health Guide

Health Behind the Supply Chain

In the logistics industry, success is defined by on-time delivery, efficient warehousing, and seamless supply chains. Yet behind every pallet moved, package scanned, and container dispatched stands a workforce exposed to ergonomic strain, fatigue, noise, chemical exposure, heavy machinery risks, and psychological stress.

As a logistics provider, you are more than a facilitator of goods, you are a legal custodian of workplace health. The Occupational Health and Safety Act, 1993 (OHSA) requires employers to safeguard the wellbeing of warehouse staff, forklift operators, truck loaders, dispatch controllers, and managers. This duty of care includes implementing a Medical Surveillance Programme that protects employees from work-related hazards while ensuring operational continuity.

Legal Foundations: Understanding Your Duty of Care

Employers in logistics, warehousing, and distribution must comply with:

• Occupational Health and Safety Act, 1993 (OHSA), Employers must identify risks, conduct HIRAs, and implement surveillance for exposed workers.
• Driven Machinery Regulations (DMR), Applies to forklifts, cranes, conveyor belts, pallet jacks, and lifting equipment.
• General Machinery Regulations, For generators, compressors, and automated handling systems.
• Noise-Induced Hearing Loss Regulations, 2003, Relevant for warehouses with conveyors, forklifts, and dock operations.
• Hazardous Chemical Agents Regulations, 2021, Applies to fuel, solvents, packaging adhesives, and cleaning chemicals in logistics facilities.
• COID Act (Compensation for Occupational Injuries and Diseases), Provides compensation for workplace injuries or occupational diseases.
• National Road Traffic Act (linked), For logistics drivers and fleet support roles.

Failure to comply exposes companies to fines, COIDA claims, reputational damage, and operational disruption.

Why Compliance Matters

• Early Detection: Identifies fatigue, back injuries, hearing loss, dermatitis, or respiratory risks.

Medical Surveillance Key Terms and Categories

Occupational Health Risks

In logistics, warehousing, and distribution, employees are exposed to a combination of mechanical, chemical, ergonomic, noise, and psychosocial hazards. Forklift operators, pickers, loaders, and dispatch staff face risks of musculoskeletal injuries, hearing loss, respiratory illness, dermatitis, fatigue, and trauma from accidents. A structured surveillance programme ensures early detection and ongoing fitness for duty.

Medical Surveillance

Medical surveillance is a legal requirement under the Occupational Health and Safety Act (OHSA, 1993). Employers must identify workplace risks, conduct hazard assessments, and ensure that employees undergo baseline, periodic, and ad hoc medicals relevant to their exposures. Employers must also complete Annexure 3 job risk profiles for each worker, which must accompany the medical assessment.

Baseline Medical

When Conducted: Before placement or role change.Purpose: Establishes an employee’s initial health status and ensures they are fit to perform logistics tasks.

Core Components:

• Medical and occupational history.
• Vision screening (distance, near, depth perception).
• Hearing test (audiometry baseline for noisy warehouses).
• Musculoskeletal examination (back, shoulders, knees, posture).
• Spirometry (dust, diesel fume exposure).
• Cardiovascular assessment (blood pressure, ECG if risk factors present).
• Skin examination (chemical dermatitis, adhesive/ solvent exposure).
• Vaccination review (Tetanus, Hepatitis B where blood or sharp exposure possible).

Frequency: Once, before employment or role change.

Risk-Based Medical

When Conducted: For workers exposed to specific risks or high-risk roles.

• Forklift Operators/ Reach Truck Drivers: Vision, hearing, MSK, reaction time, vibration assessment.
• Pickers/ Loaders/ Warehouse Assistants: MSK, ergonomic strain, skin checks (dermatitis), respiratory health.
• Drivers/ Dispatch Staff: Cardiovascular, fatigue/ sleep screening, MSK, vision.
• Cold-Store Workers: Heat/ cold stress screening, respiratory checks, musculoskeletal health.
• Supervisors: Stress/ fatigue assessments, cardiovascular checks.

Frequency: Annual or more frequent depending on risk profile.

Operator/ Driver Medical

When Conducted: For employees operating forklifts, cranes, reach-stackers, and trucks.

Key Examinations:

• Musculoskeletal exam (neck, back, shoulders, joints).
• Spirometry (diesel fume/ dust exposure).
• Cardiovascular testing (fitness for shift work and high-responsibility roles).
• Reaction time and cognitive assessment (safety-critical decisions).

Frequency: Annual for high-risk operators; biennial for lower-risk staff.

Ad Hoc or Special Medical Assessments

When Conducted: After incidents, unusual exposures, or employee-reported symptoms.

Examples:

• Post-accident medical (collision, crush, slip, or trip).
• After chemical spill or battery acid contact.
• Following diesel fume overexposure.
• Post-trauma counselling after workplace fatalities or severe injuries.
• Return-to-work fitness after long absence or illness.
