Study Notes
Machine Safeguarding
- Statutory provisions detail machine safeguarding principles
- Types of guards, their design, and selection are crucial.
- Specific guarding for wood-working, paper, rubber, printing machinery, and machine tools has specific precautions.
- Built-in safety devices, guard maintenance, and incidental safety devices and tools are vital.
- Plant/work area design for safety.
Manual Handling
- Hazards in manual handling include excessive muscular effort.
- Methods for correct lifting and handling materials include kinetic techniques.
- Maximum allowable loads for lifting/carrying are set.
- Handling differently shaped, sized, and weighted objects demands specific approaches.
- Safe use of accessories like straps for lifting/carrying improves safety.
- Material storage methods are essential.
Mechanical Handling
- Lifting machinery (cranes, elevators, conveyors, dumpers, etc.) must follow safety standards during design/construction/testing.
- Operator training on safe operation, signaling, inspection, and maintenance of lifting machinery.
- Power trucks/tractors require safety features in design/construction with safe operation, inspection, and maintenance procedures.
- Lifting tackles, slings, and accessories (hooks, shackles, etc.) have safe working loads requiring calculation.
Hand and Portable Power Tools
- Causes of tool accidents, methods for controlling accidents, and the importance of centralized tool control.
- Tool purchase, storage, supply, inspection, maintenance, and repair.
- Tool failure causes and the importance of tool tempering, finishing, and dressing are addressed.
- Safe use of hand tools (metal, wood, miscellaneous cutting, material handling, torsion, shock, and non-sparking).
- Portable power tool selection for safeguarding includes inspection, maintenance, and repair for safety.
Electrical Hazards
- Electricity dangers include amperage, voltage, and safe distances from lines.
- Conductor capacity and protection, jointing, and power cutting-off methods are critical safety steps.
- Overloading, short-circuiting, and earth-fault protection must be implemented.
- Earth, insulation, and continuity tests are important for electrical safety.
- "Borrowed" neutral protection.
- Portable electric apparatus requires flame-proof safety.
- Electrical equipment requires safe selection, installation, maintenance, and use.
- Static electricity hazards and control and the role of electricians in controlling electrical accidents are key topics.
- Indian Electricity Act and Rules.
Industrial Lighting
- Lighting purposes, benefits of good illumination, work needs, artificial lighting, illumination principles, minimum illumination standards, installation design/maintenance, color, and safety are critical considerations.
Pressure Vessels
- Fired and unfired pressure vessels require statutory provisions.
- Testing requirements and different kinds of tests (design/construction aspects for pressure vessel safety).
- Boilers require specific safety precautions and operational controls.
Ventilation and Heat Control
- Ventilation purpose, thermal environment measurement, heat regulation, thermal comfort indices, thermal limits, efficiency, and minimizing health risks.
- Natural ventilation/mechanical ventilation/air conditioning/process ventilation, heat exposure control at source, insulation, local exhaust ventilation, radiant heat control, and dilution ventilation require careful consideration.
Housekeeping
- 5S concept, management responsibility, safety engineer role, proper planning, follow-up, overall cooperation, typical accidents from poor housekeeping, unsafe housekeeping items, scrap/waste disposal prevention of spillage, gangway/location marking, color use, cleanup methods, employee assignments, inspection, and inspection checklists, results of effective housekeeping practices.
Special Precautions
- Working at height and in confined spaces.
- Work permits for working at height and in confined spaces requirements.
Laws and Regulations
- Relevant provisions within the Factories Act and Rules, Indian Electricity Act and Rules, Explosive Act and Rules, and Gas Cylinders Rules.
