1.)
What are the safe working practices and procedures to be followed when preparing and using the milling machines?
When operating a Milling machine there are a lot of health and safety laws that have to be followed when preparing to use and using a milling machine, the laws and safety precautions that must be taken are as follows:
Gloves or hand wear must never be worn whilst working on a milling machine; any types of hand wear like watches, bracelets and bangles could get snagged on the cutter and wind the operator into the machine

Coolant- coolant spills are a problem that can be prevented but on some mills there is a point where coolant leaks from the bed and drip down hitting the floor around the machine this caused by a blockage in the slots within the bed causing it to over flow with coolant creating a spillage.
Entanglement- the operator of the machine can risk entanglement from lose clothing becoming entangled in the cutter this could wind the operator into the machine cutter causing serious injury.
Sharp edges – sharp edges or burrs are a hazard when handling the components it is possible to injure yourself on these razor sharp burrs.
Training- If an operator has insufficient training then they are a danger to themselves and others around the machine
3.)
What personal protective equipment needs to be worn for the milling activities?
There is several pieces of PPE equipment that must be work whilst milling, equipment is as follows:
Before work cream: This will stop irritations and protect the skin from infections from substances being used whilst turning.
Safety glasses- protective eye wear must be worn since swarf and coolant is travelling and can be flying in any direction.
Overalls- This stops flying swarf and coolant reaching your skin and causing damage or harm.
Safety boots- safety boots are of the main pieces of PPE, this will protect the feet from swarf and coolant and there is a steel toe cap for protection against objects
Eye Protection – Is used when there is a risk of dust getting into someone’s eyes or an impact injury to the eye. There are different types of eye protection, safety goggles are made of a durable plastic and will stop both dust and flying debris from harming your eyes. Safety spectacles only protect your eyes from flying debris, these can be used when there is not a lot of dust for example cutting a brick with a bolster. Face masks are a rigid plastic visor that will protect your face from flying debris. They are commonly used with garden equipment like chainsaws and strimmer’s. They will not protect you from fine dust particles.
| Explain why and when health and safety control equipment, identified by the principles of protection, should be used, relating to moving, handling and/or storing resources, and the types, purpose and limitations of each type, the work situation, occupational use and the general work environment, in relation to:
For the novice wood worker, you may have some questions about using hand tools and power tools. It can be frustrating to know exactly how to use these tools safely and at a minimal risk to yourself. If you have a desire to work with wood and do things that you can use in your home or sell for an additional income, you can be overwhelmed with the amount of items that are available for wood work. When you are using hand tools and power tools, keep in mind that while these tools can be dangerous, they are simply tools so you can get your completed wood work project in a more Efficient. Keep these tips in mind when working with hand tools and hand tools.
Not respecting tools can leave tools in poor quality, example a file store correctly in wooden slot and protect teeth.
Leo and I met with Robertson to discuss the importance of safety and what upright standards Hensel Phelps held for all their employees, craft workers, and subcontractors. Hensel Phelps’ policy on safety was “No job is so important that it cannot be done in a safe way.” He informed us that all subcontractors and craft workers are required to fill out daily, a Activity Hazard Analysis forms. They are also to have a form documenting that they have inspected the equipment they are going to use for that day. Scissor lifts were inspected daily and operators were required to have a license approving them as an operator. Subcontractors were also required to have Safety Data Sheets (SDS) on all chemicals they were using. The data sheets detailed the dangers and the safety precautions to be observed while using the material.
As a contractor, from safety boots to hard hats, you know that being safe on the job is just as important as getting your next job. If you can stay injury free, your year will be both productive and lucrative. Not only are safety products needed for insurance purposes in the case of an accident, employers and customers both look for them and require them. From work boots to hard hats, the following five safety products will give you the best bang for your buck in terms of both safety and affordability.
Craft production comprise of skilled employees at design, machining and fitting, usage of the general purpose machines
a. To prevent injury to personnel, extreme caution should be exercised when using any types of welding equipment. Injury can result from fire, explosions, electric shock, or harmful agents. Both the general and specific safety precautions listed below must be strictly observed by workers who weld or cut metals.
Grinding is a metal cutting operation performed by means of abrasive particles rigidly mounted on a rotating wheel. Each of the abrasive particles act as a single point cutting tool and grinding wheel acts as a multipoint cutting tool. The grinding operation is used to finish the work pieces with extremely high quality of surface finish and accuracy of shape and dimension. Grinding is one of the widely accepted finishing operations because it removes material in very small size of chips 0.25 to 0.50 mm. It provides accuracy of the order of 0.000025 mm. grinding of very hard material is also possible.
When they’re on a worksite, workers should always wear the right kind of safety gear (generally known as personal protective equipment, or PPE). Depending on the nature of your worksite, proper safety gear for the head and face might include safety goggles, a hard hat or helmet, and a face shield. PPE for the legs and feet may include protective leggings and safety shoes with toe guards. To shield the arms and hands, people on a worksite may need to wear protective gloves. Fall protection gear is also essential if
Even with proper setup and equipment, it is important to provide education and training to provide awareness of potential safety and ergonomic risk factors and strategies on how to minimize their risk of exposure.
The employer must enforce the use of safety equipment such as an apron, gloves and goggles to help reduce the risk of harm whilst these tools are being operated. Guards and safety shields could also be in place to shorten the distance travelled by any material ejected from the bending jig.
Technologies involved in machining operations have advanced greatly in the recent decades and machines have experienced significant changes such as the incorporation of numerical control. Every year it is possible to observe in fairs, conferences and of course in the market economy, how production capabilities have increased thanks to the development of new concepts, devices, materials, tools, coatings, structures, etc. Accuracy, flexibility and productivity are enhanced constantly with innovative solutions to achieve market demands or even raise them to higher levels. In the end, all these improvements are possible thanks to the generation of knowledge.
Milling is metal removal process distinguished from drilling and other machining operation. It is used in most high productive manufacturing industries, where quality is essential for parts. In milling operation, Metal removal takes place due to the cutting action of a revolving milling cutter, when work piece is fed on it. But for producing quality side surface of parts, end milling operation carried out. Drill bit can cut in axial order only, while a milling bit can generally cut in all directions, although some cannot cut axially. End mills are used in milling applications such as plunging, side milling and profile milling.
The time frame and the environment within which the work is to be done in this project expose the workers and the general public to myriads of safety risks. These safety factors have an impact on the decision-making strategies in the project. In undertaking risk and safety management, the international standards especially the Commonwealth laws and the Occupational Health and Safety Act in 1991 must be considered.
