Machine guards are your first line of defense against injuries caused by machine operaon. Each machine must have adequate safeguards to protect operators and other employees in the immediate work area from hazards created by ingoing nip points, rotang parts, sparks and flying debris.

What is the importance of machine guarding safety?

Machine Guarding Moving machine parts have the potential to cause severe workplace injuries, such as crushed fingers or hands, amputations, burns, or blindness. Amputations, lacerations, and abrasions are costly and have the potential to increase workers’ compensation premiums.

(Amputation is one of the most severe and crippling types of injuries in the occupational workplace, often resulting in permanent disability.) Due to this fact, OSHA (Occupational Safety & Health Administration) has established a set of standards around machine guarding. The purpose of machine guarding is to protect the machine operator and other employees in the work area from hazards created during the machine’s normal operation.

This would include hazards of concern such as: ingoing nip points, rotating parts, reciprocating, transversing, and/or flying chips & sparks. Any machine part, function, or process that might cause injury must be safeguarded. When the operation of a machine or accidental contact with it could injure the operator or others in the vicinity, the hazards must be either controlled or eliminated.

4. Machinery Guards for the Health and Safety of Workers

Protective guards on machinery and equipment can greatly assist in the prevention of injuries and accidents caused by part of a person’s body accidentally coming into contact with dangerous parts of the machine. These parts can be dangerous for one or more reasons, including being sharp, being hot, being extremely cold (e.g.

• Cryogenic storage), having a risk of entanglement, trapping or crushing to name just a few.
• However, whilst guards can greatly improve the levels of health and safety within a workplace, if they are poorly designed or implemented incorrectly then they can actually contribute and increase the risks to workers, which completely goes against the reasons for having them at all.

As a guard will be there to prevent contact between the danger area and part of a person’s body, a number of guards will partially block or obstruct the view of the operator which may make them more likely to make a mistake and have an accident. Many guards will only partially prevent the opportunity for incidents, as for example in a disc cutter there needs to be a gap to get the wood or other material to the blade which a person could still put their fingers through.

A guard which prevents clear sight may force the operator to get their eyes or fingers closer to the blade in order to carry out the work, with the subsequent increased risk of injury. Guards which are in place on machinery involved in industries such as food preparation or medicine production will require regular cleaning and sterilisation, otherwise they risk introducing harmful bacteria into the products if this was allowed to grow unchecked on the guard.

The material that the guard is made out of will also play a part in overall health and safety either to the operator of the equipment or to the consumer purchasing the finished product. If it is not strong enough to cope with the strains and stresses placed on it then it may be unfit for purpose.

• If the guard reacts with the material or ingredients being processed it could contaminate or damage them.
• The protective guard must not interfere too much with the cooling of the machinery.
• Although measures such as meshing will affect the cooling to a small but acceptable degree, too much of an affect may cause the machine to overheat with the subsequent risks of fire and explosion that could ensue.

Although not relevant to most types of equipment, guards added to portable machinery may significantly add to its weight and/or dimensions. This can increase the potential for manual handling related injuries caused by the lifting, carrying and moving of the equipment.

1. Guards which are loose or are not fitted correctly to machinery which vibrates or has high speed rotating parts my cause excessive noise which could damage the hearing of the operator and those nearby, especially if they are exposed to it over a long period of time.
2. The safe use of work equipment including the importance of protective guards are covered in health and safety training courses such as the NEBOSH Diploma, NEBOSH General Certificate, NEBOSH Construction Certificate and CITB SMSTS and SSSTS courses.

Please use the “Health & Safety Training” tab at the top of the page to find out more information regarding these courses. Many types of machinery and pieces of equipment are powered by motors. Whether they are powered by fuel or run off electricity, these motors will contain spinning or revolving parts, and can get extremely hot.

• Cuts, lacerations or possible amputation from blades
• Burns from hot surfaces, steam or hazardous chemicals
• Impacts from loose parts which fly off
• Crushing injuries from getting a part of the body trapped between moving parts

To prevent this, guards should be fitted where practicable wherever there is a danger, as well as the presence of warning signs and providing workers with health and safety training courses to make them more aware of the dangers that they face from the various pieces of equipment that they work with or around.

The features of these guards should prevent injury whilst still allowing the machinery to operate correctly, for example fan casings with holes which allow air to move freely but are not big enough for a person to get their finger through them. Some workers may be tempted to remove the guards on occasions, for example to try and make the equipment lighter if it needs to be manually handled or to fix an issue which is preventing the machine from working.

This removal of protection can present a serious risk to their health and welfare, but can be combated by locking the guard into place with specialist tools that are not available to anyone other than suitably trained individuals i.e. competent maintenance people.

What is a safety consideration when using a machine guard?

Secure: Workers should not be able to easily remove or tamper with the safeguard, because a safeguard that can easily be made ineffective is no safeguard at all. Guards and safety devices should be made of durable material that will withstand the conditions of normal use. They must firmly be secured to the machine.

What are the benefits of machine guarding?

Keep Employees and Visitors Safe – Safety fencing machine guarding is used to keep employees and expensive equipment safe. All factories, warehouses, and businesses that utilize automated machines need to use machine guarding for safety purposes. Machine guarding is a simple, effective way to keep personnel from the dangers posed by automated equipment.

It also doubles as a way to keep people away from malfunctioning equipment. If you have a machine down or malfunctioning, you can use machine guarding as a way to block the machine off. The dangers of automated machines include airborne debris, fumes, smoke, heat, sparks, spray/mist/fluids, and mechanical movement.

Machine guard fencing prevents these dangers from injuring an employee. Injuries can range from crushed fingers to burns to blindness. Machine guard fencing is also necessary to keep visitors in your business safe, whether it’s students on a field trip or a visitor from another office.

What are the 3 basic areas that need machine guarding?

Machine Guarding eTool All machines consist of three fundamental areas: the point of operation, the power transmission device, and the operating controls.

What is an example of a machine guard?

Examples include shields to contain chips, sparks, sprays or other forms of flying debris ; holding tools that an operator can use to handle materials going into the point of operation; and awareness barriers to warn people about hazards in the area.

What are two safety requirements that relate to machine guards?

The guard must be of solid construction and securely mounted so, as to resist impact or shock and avoid using light brittle material. Where there is a risk of flying or ejected parts, the strength of the material should be sufficient to contain the parts. the danger point through the openings.

What are three characteristics of a good machine guard?

Twelve characteristics, design principles, specifications, basic requirements or good guarding practice for machine guarding are:- –

1. With its primary purpose of protection, it should also facilitate the work it should be convenient, reliable arid not hampering the work or rate of production.
2. It should fully satisfy the legal provision is prescribed it should confirm the standards, be a complete guard at incomplete or giving any access to the part to be protected. It should be as close as possible.
3. It should allow for oiling, inspection, adjustment, and repair. If it repairs opening for this purpose, it should be easily and quickly replaceable.
4. It should be suitable and effective for the machine. It should not weaken the machine.
5. It’s would be the withstand wear, shock, vibration long use with minimum maintenance required. This becomes more important and if it factors becomes more important.
6. If dusting is possible as in case of the machine of wood, rubber, brass, cast iron, etc. Apart from the guard, a dust suction device should also be fitted as a special guarding.
7. It should be of proper material and construction it should well fitted, fire and co-resistance material is preferable.
8. It should be free from a self hazard such a sharp, nails, splinters, more opening noise, vibration, etc.
9. It should be inter-locking type, the machine will not start till it is not closed and soon if it is open.
10. If a visual watch of operation is necessary, it should be transparent and yet durable.
11. It should fulfill a special requirement depending upon its purpose distance guard must immediately trip the machine, It may be difficult to fulfill all these requirements provide sufficient protective distance, the Trip guard must immediately trip the machine, etc. It may fulfill all these requirements but it is desirable that safety engineers must guards by keeping above points in mind. If possible to provide guard without interfering production, safety should be preceded over production similarly when complete protection is not incomplete, protection should prefer to no protection.
12. It should be fail-shape if it fails or be the stop the machine or at least it gives a warning (alarm to stop the machine)

Who is responsible for machine guarding?

To Guard, or Not to Guard, That May Not Be the Only Question

• Vice President, Casualty Loss Control Specialist Associate Vice President, Complex Claims Consultant

The law mandates employers ensure machinery in their plants is properly guarded. Unguarded or poorly guarded equipment is a costly problem, which impacts workers’ compensation claims, purchasing workers’ compensation coverage, and, most significantly, the human side of loss.

1. Simply put, OSHA views this as a basic responsibility of the employer irrespective of the availability of cost effective solutions or liability issues.
2. Machine guarding and lock out tag out regulations are closely related, and both are consistently on the,
3. This is likely not news to anyone working in safety in general manufacturing, processing, woodworking, metalworking, or a host of other industries.

These OSHA standards, as well as the desire to keep good employees around and keep them happy and healthy, make machine guarding a popular topic. For these reasons, sometimes creative, internally designed and built solutions to machine guarding problems can be found in older plants and on older equipment. In some cases, the equipment manufacturer has long since ceased to exist, and in other cases the cost of manufacturer produced guarding is high or takes a long time to procure.

Additionally, an employer may have initially built portions of a machine themselves because the manufacturer failed to produce retro fit kits or guarding that fits a unique machine placement condition. In these cases, employers with internal shops and fabrication capabilities sometimes look to solve the issue themselves.

OSHA Machine Guarding: Where to find OSHA regulations for each type of machine is sometimes a little confusing. Ensure that you look deep to make sure you are getting the information you need. Note that some industries have their own regulation such as 1910.265 for sawmills which add some guarding requirements for machines within that specific industry.

What is the basic principle of machine guarding?

A machine guarding:- – Means any sure, barrier or device constructed to prevent a person or his clothing coming into contact with dangerous parts of the machine. The point of operation is that part of the working machine at which cuffing, shaping, forming or any other necessary operation is accomplished. A guard for that part is known as the point of operation guard.

When it comes to machine safety What’s the most important safeguard?

What Makes a Proper Guard? – A properly designed and installed guard will protect workers from mechanical hazards without impeding their ability to complete their tasks. To be considered safe and effective, these minimum requirements must be met for all guards:

Prevent Contact. The guard must physically prevent hands, arms, or any other part of a worker’s body from contacting moving parts. A good safeguard will eliminate any possibility of the worker from placing any part of their body near hazardous moving parts. Secure. Safeguards should not be easy to remove or be tampered with. Guards must be durable enough to withstand the conditions of normal use and firmly secured to the machine. Protect from Falling Objects. No objects should be able to fall into moving machine parts, including small tools, debris, etc. No New Hazards. If a safeguard creates a different hazard, it has defeated its purpose. An example is a newly created shear point or an unfinished edge of a guard that could cause a laceration. Guard edges should be rolled or bolted in such a way that sharp edges are eliminated. No Interference. Safeguards must not impede workers from performing their tasks quickly and comfortably, or workers may override or disregard them. Proper safeguarding can often enhance efficiency as they reduce apprehension regarding injuries. Allow Safe Lubrication. The machine should be easily lubricated without removing safeguards whenever possible to reduce the need for operators or maintenance workers entering the hazardous area.
