Introduction
The coffee industry involves numerous processes from cultivation to processing and distribution, each presenting unique occupational safety and health (OSH) challenges. Workers across the coffee value chain face various hazards ranging from physical and chemical exposures to ergonomic and psychosocial risks. Implementing a systematic approach to identifying hazards, assessing risks, and evaluating control measures is essential for protecting worker health while maintaining operational efficiency.
The methodology outlined in this document provides a structured framework specifically tailored to the coffee sector, applicable to small plantations, medium-sized processing facilities, and large industrial coffee operations. By following this systematic approach, coffee sector employers can develop comprehensive OSH management systems that comply with international standards and local regulations while improving working conditions.
Methodology Overview
This methodology follows a five-step approach to OSH risk management, each building upon the previous one to create a comprehensive safety management system:
This cyclical process ensures continuous improvement of workplace safety conditions through regular identification of new hazards, reassessment of existing risks, and refinement of control measures based on performance monitoring.
Hazard Identification in the Coffee Sector

- Noise during processing and grinding operations
- Sharp objects during maintenance and repair
Chemical Hazards
- Pesticides, herbicides, and fertilizers in cultivation
- Cleaning agents and sanitizers
- Flavoring additives and preservatives
- Coffee dust (respiratory irritant)
- Exhaust fumes from machinery
- Carbon monoxide from roasting equipment
Biological Hazards
- Mold growth on beans during storage

- Vibration from hand tools and equipment
Psychosocial Hazards
- Production targets and deadlines
- Irregular working hours during peak season
- Limited worker participation in decision-making
- Seasonal employment insecurity
- Low wages in some regions
Hazard Identification Methods
1. Workplace Inspection
A systematic walkthrough of all work areas, focusing on processes, equipment, and work practices. Include seasonal variations and different operational periods.
2. Worker Consultation
Interviews, surveys, and structured discussions with workers at all levels. Workers often have unique insights into hazards observed during their daily tasks.
3. Incident Record Review
Analysis of past incidents, near misses, first aid cases, and occupational illnesses to identify patterns and recurring hazards.
4. Process-Specific Checklists
Use tailored checklists for each coffee production process: cultivation, harvesting, processing, roasting, and packaging.
5. Direct Observation
Shadowing workers during different tasks to understand potential hazards that may not be evident from documentation alone.
6. Job Safety Analysis (JSA)
Breaking down complex jobs into individual steps to identify hazards at each stage and develop control measures.
Risk Assessment
Risk Assessment Process
For each identified hazard, assess the level of risk by considering the following factors:
- Likelihood of occurrence: How probable is the hazardous event?
- Severity of harm: What would be the potential degree of injury or ill-health?
- Number of exposed workers: How many workers could be affected?
- Duration and frequency of exposure: How long and how often are workers exposed?
Risk Assessment Matrix
The standard 55 risk assessment matrix can be used to determine overall risk levels for each hazard:
| Likelihood \ Severity | Insignificant | Minor | Moderate | Major | Catastrophic |
|---|---|---|---|---|---|
| Very High | Medium | High | High | Very High | Very High |
| High | Low | Medium | High | High | Very High |
| Medium | Low | Medium | Medium | High | Very High |
| Low | Low | Low | Medium | Medium | High |
| Very Low | Low | Low | Low | Medium | Medium |
Coffee Process-Specific Risk Assessment
Cultivation Phase
- Climate-related risks (heat stress, UV exposure)
- Pesticide and fertilizer exposure
- Heavy machinery operation
- Physical labor in difficult terrains
- Tool-related injuries
Harvesting Phase

- Heat exposure and dehydration
- Carrying heavy loads of cherries
- Slips, trips, and falls on slopes
- Repetitive motion injuries
Processing Phase
- Machinery operation and guarding
- Chemical exposure during cleaning
- Dust inhalation
- Electrical hazards in wet environments
- Near drowning in fermentation tanks
Roasting and Grinding Phase
- High temperature burns
- Dust explosion risks
- Machinery guarding failures
- Noise-induced hearing loss
- Chemical exposure from smoke
Packaging Phase
- Repetitive strain injuries
- Chemical exposure from inks and adhesives
- Machinery-related hazards
- Cutting tool injuries
- Pallet jack injuries
Risk Evaluation
Risk Prioritization
After assessing risks, they should be prioritized based on several factors:
- Risk rating from assessment matrix
- Legal requirements and compliance obligations
- Number of workers exposed to the hazard
- Potential business impact (production delays, reputation damage)
- Technical and financial feasibility of control measures
Risk Acceptability Criteria
Establishing clear criteria for acceptable risk levels helps determine response priorities:
- Very High Risks: Immediate action required, operations may need suspension until controls are implemented
- High Risks: Action within short timeframe (e.g., one week), temporary controls may be necessary
- Medium Risks: Action within defined period (e.g., one month), scheduled into planning
- Low Risks: Regular monitoring, addressed through maintenance and routine procedures
Control Measures
Hierarchy of Controls
The hierarchy of controls provides a systematic approach to selecting and implementing risk control measures:
- Elimination: Redesign process to remove hazard completely
- Substitution: Replace hazardous materials or processes with less hazardous alternatives
- Engineering controls: Isolate workers from hazards through equipment modification
- Administrative controls: Change work practices and policies to reduce exposure
- Personal Protective Equipment (PPE): Protect the worker when other controls are not sufficient
Coffee Sector-Specific Controls
