Hazards associated with the operation of metal cutting / processing machinery
Electricity Cutting / processing machinery operation requires a minimum of 24 volts and a maximum of 440 volts This is what can happen when the human hand comes into contact with electricity This is the hand of a qualified electrician. (The pictures were taken 2 days apart) If you’re not a qualified electrician you’re not authorised to repair anything electrical
Mechanical All processing equipment has moving parts which include vices, feed carriages, band wheels, swarf conveyors, cooling fans, powered rollers, swarf cleaning brushes and the blade it’s self. It is a legal requirement that any moving part is guarded to prevent it from causing an injury to the operator. The guards can be fixed guards, safety interlocks even light barriers which stop the equipment when a light beam is broken
Fixed Guards Interlocks
Mechanical You Must Not ! Operate equipment which does not have all the guards securely fitted Operate equipment which has inoperative safety interlocks Try to remove cut material from close to a moving saw blade You must not place any part of your body close to a moving saw blade Report any defective equipment to your supervisor after you have safely isolated the equipment from use
Noise Noise produced from the operation of cutting / processing equipment can at times exceed 85db (a) All employees are issued with hearing protection which must be worn at all times in the processing area or anywhere you see this sign
Manual Handling Anyone Hurt?
Accident Statistics Largest cause of accidents at work 37% Manual Handling 20% Struck by an Object 19% Slips, Trips and Falls 12% Other Causes 7% Falling from Height 5% Machinery
Accident Statistics Interpreted another way - the overall figure of 37% means that: 86,000 people are absent from work daily 26,500,000 working days are lost annually £1,000,000,000 is lost in production, sickness benefit and medical costs In terms of suffering each injury results in an average of 20 days off work and some people never fully recover. Four out of five people suffer with back related problems at some time but the risk is greater after the age of 30.
Definition of Manual Handling The transporting or supporting of a load by hand or some other part of the body including the lifting, putting down, pushing, pulling, carrying, moving or intentionally dropping or throwing of a load
400 Muscles 118 Joints 33 Vertebrae 31 Pairs of Nerves 24 Discs 1 Spinal Cord Total Number of Parts 607 approximately The Human Back Parts List
Kinetic Lifting One Person Lift Determine the weight Look for sharp edges See if weight is evenly distributed Keep heaviest side to body Decide how to hold the load If you think it is too heavy use a crane or get assistance
Correct Positioning of Feet Comfortably apart One foot positioned in direction of movement Other foot where it can give maximum thrust to the body To maintain good balance feet should never be too close together on the ground Kinetic Lifting
Straight Back Lower the body by relaxing the knees Keep your back straight (but not vertical) Keep load close to body Keep chin in and head back Kinetic Lifting
Lifting If lifting from ground make maximum use of legs Keep back straight but inclined forward As lift proceeds and the legs are straightened the back returns to vertical position Positioning of feet and bending of knees are the key factors in maintaining a straight back Kinetic Lifting
Correct Grip Take a firm grip by using the palms of the hands and roots of fingers Taking weight on finger tips will create pressure at the end of fingers and could strain muscles and tendons in the arms A full palm grip will reduce muscle stress to the arms and decrease the possibility of the load slipping Kinetic Lifting
Lifting Smoothly Thrust from back foot and straightening of knees will move body forwards and upwards and briefly off balance Immediately countered by bringing the back foot forward as if walking The lift now completed forward movement results in smooth transition from lifting to carrying Kinetic Lifting
Carrying the Load Make sure you can see where you are going Avoid twisting the body move your feet instead If you need to change your grip set the load down don’t attempt to adjust whilst walking Setting the Load Down Use the correct stance for lifting and set the load down gently Kinetic Lifting

Chemicals Or Skin Cancers
An inspection of the processing machinery and associated area must be performed and recorded on the machine inspection log at the start of each shift. The inspection must include but is not restricted to the following items: A visual inspection of all walkways around the machinery that you will be operating and any walkways you may need to use for safe access or egress. Remember at all times that poor housekeeping procedures can cause injuries through slips, trips and falls. Any obstruction or defect identified on the visual inspection must be immediately reported to your supervisor The Pre-Shift Inspection
The Pre-Shift Inspection A visual inspection of the machinery that you have been designated to use must be done to ensure that it is clean, all lubricants and hydraulic oils are at the required levels, and that all electrical panels and safety guards are securely fastened. Any defect identified on the visual inspection must be immediately reported to the supervisor As hydraulic oil is classed as a hazardous substance the hydraulic system should be checked visually to identify any leaks but you should also work all hydraulic motions of the machinery to their maximum capacity to ensure their correct operation.
The Pre-Shift Inspection If you identify a leak in the hydraulic system isolate the machine and report the fault. If you are contaminated with hydraulic oil wash the area immediately with soap and water If you get hydraulic oil in your eye wash it with copious amounts of water and seek immediate medical attention
Following the visual inspection of the machinery you must check for the correct operation of the cutting machinery. You must ensure that all emergency stop switches and safety interlocks on the machinery operate correctly. Further checks should then include the correct operation of all moving parts such as the operating switches, feed carriage, vices, powered rollers, swarf conveyors and blade lift and lower operations. Remember that all moving parts have the potential to cause injury so ensure that you are aware of others in the vicinity of the machine and maintain your own personal safety during these checks. The Pre-Shift Inspection
Fixed Guards Interlocks Emergency Stop
A pre-shift inspection does not only include the equipment you will be operating it also includes any personal protective equipment issued by the company must be worn in the cutting areas. Overalls, safety shoes and gloves must be worn at all times. Eye and hearing protection must be worn in the designated protection areas If your personal protective equipment is damaged or if you consider it is sub-standard please see your supervisor who will replace it. The Pre-Shift Inspection
Video: My Precious Eyes
The use of materials handling equipment such as fork lift trucks and pendant controlled overhead cranes and associated lifting accessories is essential in the processing area operations. You must at all times follow the safe operating procedures that you have been taught. You must at the start of each shift perform the pre-shift inspection of the cranes and associated lifting tackle or forklift truck that you will be using. The Pre-Shift Inspection
Band Saw Blade Safety It should always be remembered when handling bandsaw blades that they are potentially dangerous and the following precautions should be followed: When fitting band saw blades to equipment or removing them for re-sharpening or disposal Always wear your safety gloves, overalls and face protection, i.e. goggles or a visor when handling blades. Safety glasses should be worn at all times in the designated sawing area.
1.Ensure that your personal protective equipment is in good order and correctly fitted 2.Remove the coiled and tied bandsaw blade from the box. 3.Remove the containment ties fitted around the blade bearing in mind at all times that the blade is under tension and may spring open. 4.Hold the loops vertically with the teeth towards you and allow the loops to open slightly. Band Saw Blade Safe Handling Procedure
5. Select the loop which will allow the band to open, (only one loop will do this). Drop this loop onto the floor whilst holding the other two and allow the whole band to open gradually in a controlled manner. The blade is now open and ready for fitting to the machine. 6. Ensure that the cutting direction of the teeth conforms to the direction of the machines band wheels. If this is not the case carefully turn the bandsaw blade inside out. Band Saw Blade Safe Handling Procedure
Band Saw Blade Safe Handling Procedure When re-coiling a bandsaw blade for disposal or storage you must always wear your personal protective equipment and follow the training you have received. The re-coiling of a bandsaw blade is quite easy to demonstrate but difficult to describe. First of all hold the bandsaw blade in front of you as if looking at a clock face with your hands holding the blade in the three and nine o’clock positions with both of your thumbs pointing forwards.
Band Saw Blade Safe Handling Procedure Now push / use pressure from both hands whilst in this position to force the top of the blade away from your body down towards the floor. Once the blade starts to flex turn your wrists in opposite directions and the blade should re-coil. It does take some practice to perform this task and the bigger the blade the harder it can be so good luck and don’t forget to wear your protective equipment and store or dispose of the blades in the correct areas.
Remember Safety is paramount at all times You are responsible for your Health and Safety and that of anyone who may be affected by what you do or don’t do You must not under any circumstances allow anyone to operate the processing machinery unless they are trained and authorised to do so. And you must work to the training you have received at all times Any Questions? To Recap
