Study Notes
Machine Guarding
- Statutory provisions govern machine guarding principles.
- Types of guards (e.g., fixed, interlocked) are designed and selected based on machine type.
- Specific precautions for woodworking, paper, rubber, and printing machinery, and machine tools are crucial.
- Built-in safety devices and routines for maintaining and repairing guards are essential.
- Incidental safety devices and tools are important.
- Plant/work area design impacts safety.
Manual Handling and Storage
- Hazards in manual handling include excessive muscular effort.
- Correct lifting/handling techniques (kinetic methods) minimize risk, and maximum load limits must be followed.
- Safe use of handling accessories is critical for objects of various shapes, sizes, and weights.
- Proper material storage reduces risk.
Mechanical Handling
- Safety considerations are paramount in the design, construction, and testing of lifting machinery (cranes, elevators, conveyors, dumpers, etc.).
- Operator training includes safe operation, signaling, inspection, and maintenance procedures for these machines.
- Power trucks and tractors require safe design features, operation, inspection, and maintenance.
- Lifting tackles (chain slings, rope slings, fiber and wire rings, hooks, shackles, swivels, eye bolts) have safety features.
- Safe working loads must be calculated for lifting tackles.
Hand Tools and Portable Power Tools
- Tool accidents are caused by factors that must be controlled (e.g., poor maintenance).
- Centralized tool control systems improve safety.
- Procurement, storage, and supply of tools are critical to safety.
- Tools need regular inspection, maintenance, and repair.
- Understanding tool failure causes (e.g., tempering needs) and proper handling, including dressing, is necessary.
- Proper handles are essential for safe tool use.
- Tool types are classified by use (metal cutting, wood cutting, etc.), including torsion tools, shock tools, and non-sparking tools.
- Portable power tools must be selected, inspected, maintained, and repaired for safe use.
Electrical Hazards
- Electricity poses hazards, with amperages, voltages, and distance from lines influencing safety.
- Conductor capacity and protection, safe joints and connections, and power-off mechanisms are essential.
- Overload and short circuit protection and earth fault protection are needed.
- Earth, insulation, and continuity tests protect against hazards.
- Precautions against overvoltage from "borrowed" neutrals are necessary.
- Portable electrical apparatus must be flameproof.
- Precautions in selecting, installing, maintaining, and using electrical equipment are important.
- Static electricity control measures are needed.
- Electricians play a crucial role in controlling electrical accidents.
- The Indian Electricity Act and Rules apply.
Industrial Lighting
- Lighting is crucial for safety and productivity.
- Good illumination provides advantages.
- Artificial lighting sources and types are various.
- Principles of good illumination (e.g., light intensity, positioning) are critical.
- Minimum recommended illumination standards exist.
- Effective lighting installation design, maintenance, lighting, and color are necessary.
Safety of Pressure Vessels
- Statutory provisions govern fired and unfired pressure vessels.
- Testing requirements and different testing types are mandated (e.g., pressure tests).
- Safety is essential in the design and construction of these vessels.
- Safety in boilers, operation, and safety precautions are key.
Ventilation and Heat Control
- Ventilation is essential for safety.
- Thermal environment measurement, thermal comfort, and indices of heat stress are all factors in safety.
- Thermal limits for comfort and efficiency, free from health risks, are essential.
- Natural, mechanical, air conditioning, and process ventilation are types of ventilation.
- Controlling heat exposures (at source, insulation, etc.) is crucial.
- Control of radiant heat and local relief are necessary.
Housekeeping
- The 5S concept (sort, set in order, shine, standardize, sustain) is crucial for safety.
- Management responsibility, safety engineers' role, and overall cooperation are vital.
- Proper planning and follow-up, and prevention of spills are critical.
- Marking gangways, etc., and use of color coding improves housekeeping.
- Clean-up campaigns, cleaning methods, employee assignments, inspection, and checklists are key.
- Good housekeeping improves safety outcomes.
- Scrap and waste disposal are important safety elements.
Special Precautions (Working at Height, Confined Spaces)
- Special precautions are required for working at height and in confined spaces.
- Work permits are necessary for such tasks.
Laws and Regulations
- Relevant provisions from the Factories Act, Indian Electricity Act, Explosive Act, and Gas Cylinders Rules must be followed.
