1. Purpose
The purpose of this JSA is to identify and mitigate potential hazards associated with the operation of the Dedusting Conveyor for Tablets. This equipment is used in pharmaceutical manufacturing to remove excess powder or dust from tablets before further processing or packaging. Proper handling and operation are essential to ensure product quality, prevent contamination, and maintain workplace safety.
2. Scope
This JSA applies to all operators, supervisors, and maintenance personnel involved in using, cleaning, and maintaining the Dedusting Conveyor for Tablets in the Oral Dosage department. Ensuring compliance with safety measures minimizes risks associated with airborne dust, mechanical hazards, and improper equipment calibration.
3. Responsibilities
Operators:
- Follow the standard operating procedure (SOP) while operating the Dedusting Conveyor.
- Ensure the machine is properly calibrated before use.
- Wear appropriate Personal Protective Equipment (PPE) to prevent exposure to airborne dust.
- Monitor tablet movement and ensure proper dedusting.
- Ensure proper cleaning and avoid cross-contamination between batches.
- Report any machine malfunctions immediately to the supervisor.
Supervisors:
- Ensure compliance with GMP and workplace safety regulations.
- Monitor machine efficiency and ensure calibration is performed as scheduled.
- Conduct routine inspections of the Dedusting
Conveyor and maintenance logs.
Safety Officers:
- Perform risk assessments and ensure compliance with occupational safety standards.
- Ensure that dust control and ventilation systems are functioning correctly.
- Verify that PPE, such as respirators and protective gloves, are used correctly.
4. Definitions & Abbreviations
- PPE: Personal Protective Equipment (e.g., gloves, safety glasses, respirators).
- GMP: Good Manufacturing Practices – Guidelines ensuring product quality and worker safety.
- LOTO: Lockout/Tagout – A procedure to isolate hazardous energy sources.
5. Procedure
| Step | Task Description | Potential Hazard | Risk Level (L/M/H) | Control Measures |
|---|---|---|---|---|
| 1 | Machine setup and calibration | Electrical hazards, incorrect calibration | Medium | Ensure proper grounding and calibration before operation. |
| 2 | Loading tablets onto the conveyor | Manual handling strain, tablet contamination | Medium | Use clean handling tools; wear gloves. |
| 3 | Adjusting conveyor speed and airflow | Dust exposure, incorrect dedusting | High | Follow SOP guidelines for setting dedusting parameters. |
| 4 | Dedusting process | Airborne dust, tablet damage | High | Ensure proper dust extraction and avoid excessive airflow. |
| 5 | Unloading and collecting dedusted tablets | Cross-contamination, handling errors | Medium | Follow GMP cleaning procedures and use designated collection containers. |
| 6 | Cleaning and maintenance | Residual powder exposure, electrical shock | High | Follow LOTO procedures before servicing; wear PPE during cleaning. |
6. Risk Assessment
| Likelihood | Consequence | Risk Level |
|---|---|---|
| Rare | Minor tablet misalignment | Low |
| Possible | Tablet rejection due to incomplete dedusting | Medium |
| Likely | Dust inhalation causing respiratory discomfort | High |
7. Emergency Procedures
- In case of excessive dust exposure, move to fresh air and seek medical assistance.
- If the system malfunctions, shut it down and report to maintenance.
- For equipment entrapment, activate the emergency stop and seek immediate assistance.
- All incidents must be reported and logged for investigation.
8. Required PPE & Safety Controls
- Respiratory mask: Prevents inhalation of airborne dust.
- Safety glasses: Shields eyes from fine dust exposure.
- Protective gloves: Prevents direct contact with tablets.
- Machine guards: Ensures safety from moving parts.
- Dust extraction unit: Reduces airborne powder concentration.
