1. Purpose
The purpose of this JSA is to identify and mitigate potential hazards associated with the operation of the Drum Blender. The Drum Blender is widely used in the pharmaceutical industry for blending powders and granules in a controlled environment. Proper operation of this equipment ensures homogeneity of materials while minimizing contamination risks and safety hazards.
2. Scope
This JSA applies to all operators, maintenance personnel, and supervisors involved in the operation, cleaning, and maintenance of the Drum Blender in the Oral Dosage department. Ensuring compliance with safety protocols is necessary to reduce risks associated with moving parts, handling raw materials, and maintaining hygiene.
3. Responsibilities
Operators:
- Operate the Drum Blender following the approved standard operating procedure (SOP).
- Ensure the drum is properly secured before starting the blending process.
- Wear appropriate Personal Protective Equipment (PPE) before handling raw materials.
- Monitor machine parameters and blending cycles for abnormalities.
- Thoroughly clean the Drum Blender after each batch to prevent cross-contamination.
Supervisors:
- Ensure operators follow all safety measures and standard procedures.
- Conduct periodic inspections to identify hazards and enforce corrective actions.
- Provide training on emergency shutdown and safe material handling procedures.
Safety Officers:
- Conduct risk assessments and ensure the equipment meets safety compliance standards.
- Ensure all operators are trained in emergency response and equipment handling.
- Verify that PPE is being used correctly and consistently.
4. Definitions & Abbreviations
- PPE: Personal Protective Equipment (e.g., gloves, goggles, dust masks).
- LOTO: Lockout/Tagout – A safety procedure to isolate hazardous energy.
- Risk Assessment: A systematic approach to identifying and mitigating hazards.
