Hot Rolling ProcessIn hot rolling process, burns and eye injuries may be caused by flying mill scale; splash guards can effectively reduce the ejection of scale and hot water. Eye injuries may be caused by dust particles or by whipping of cable sling; eyes may also be affected by glare.
Personal Protective Equipment (PPE) is of great importance in the prevention of rolling mill accidents. Hard hats, safety shoes, gaiters, arm protection, gloves, eye shields and goggles should be worn to meet the appropriate risk. It is essential to secure the cooperation of employees in the use of protective clothing. Training, as well as an effective accident prevention organization in which workers or their representatives participate is important.Heat. Radiant heat levels of up to 660 degree celcius have been measured at work points in rolling mills. Heat stress diseases are a concern, but workers in modern mills usually are protected through the use of air-conditioned pulpits.Large amounts of degreasing agents are used for the finishing operations.
These agents evaporate and may be inhaled; their action is not only toxic, but also causes deterioration of the skin, which may be degreased when solvents are not handled properly. LEV should be provided and gloves should be worn.Stamping Metal ProcessSome reduction in die lubricant mist concentrations is possible with careful management of the application procedure in stamping. Roll application in stamping is preferred when feasible, and using minimal air pressure in sprays is beneficial. Possible elimination of priority hazardous ingredients should be investigated. Enclosures with negative pressure and mist collectors can be highly effective but may be incompatible with parts handling. Filtering air released from high-pressure air systems in presses would reduce press oil mist (and noise). Skin contact in stamping operations can be reduced with automation and good personal protective wear, providing protection against both laceration and liquid saturation.
For stamping plant welding, washing parts prior to welding is highly desirable, and partial enclosures with LEV would reduce smoke levels substantially.Controls to reduce heat stress in stamping minimizing the amount of manual material handling in high-heat areas, shielding of furnaces to reduce radiation of heat, minimizing the height of furnace doors and slots and using cooling fans. The location of cooling fans should be an integral part of the design of air movement to control mist exposures and heat stress; otherwise, cooling may be obtained only at the expense of higher exposures.Mechanization of material handling, switching from hammer to press stamping when possible and adjusting the work rate to ergonomically practical levels can reduce the number of musculoskeletal injuries.Noise levels can be reduced through a combination of switching from hammer to press stamps when possible, well-designed enclosures and quieting of furnace blowers, air clutches, air leads and parts handling. A hearing conservation programme should be instituted.PPE needed includes head protection, foot protection, goggles, hearing protectors (around are as with excessive noise), heat- and oil-proof aprons and leggings (with heavy use of oil-based die lubricants) and infrared eye and face protection (around furnaces).Pickling ProcessPickling use strong acids (Sodium Hydroxide) and normal precautions for safety should be followed.
Pickling chemicals must only be handled by persons with a sound knowledge of the health hazards associated with such chemicals. This means that the material safety data sheet (MSDS) and the product label must be thoroughly studied before the chemicals are used.Employees handling pickling chemicals must wash their hands and faces before eating and after finishing work.
Thermal Spraying ProcessSelect suitable lens lenses that provide adequate protection for the eyes and are comfortable by doing this process.Heating process must always use the appropriate helmet or head cover, face and eye during a process involving heating and diluting ceramic.Application. The process of generating UV light. Wear flame-proof clothing that provides full coverage for the skin so as not to burn the skin.Use earplugs when spraying heat to prevent noise, fireworks and melting metals from damaging your ears.
Use non-combustible welding / heat screens to protect others.Riveting processHealth & safety implications for reveting processes are relatively small compared to some widely used component assemblies.Unlike obstacles, for example, self-piercing riveting the pan cooking does not produce smoke, heat and spatter. It is also a relatively calm process.However, safety glasses should be worn at all times, and care must be taken to avoid personal injury caused by traps of fingers, for example, between punch and die.
Various steps can be taken to minimize risk, from dual-hand control to remote-controlled machines.Suitable gloves should be worn when handling sharp edges of sheet material and components.Before starting a new application, Risk Assessment needs to be done as a major step in ensuring safe operation.Thermoplastic Injection MoldingEmployees must have the great knowledge about Thermoplastic Injection Molding Machine to ensure their safety during using Injection Molding machine.
They have to wear a safety glasses at all times in their work station and wear appropriate footwear while working. Jewellery and rings must be removed that have on your body and not be worn while working.Long and loose hair must be contained.Close fitting/protective clothing must be worn.Gloves must be worn when using this machine.
