Mechanical Safety: Machinery Hazards & Control Measures

Every day, workers are injured on the job as a result of machinery hazards. In some cases, these injuries are fatal. It is important for employers to understand the dangers associated with machinery and take steps to protect their workers. Most machinery has the potential to cause injury to people.

These injuries may range in severity from a minor cut or bruise, through various degrees of wounding and disabling mutilation, to crushing, decapitation, or other fatal injuries. It is not solely powered machinery that is hazardous, for many manually operated machines (e.g. hand-operated guillotines and fly presses) can still cause injury if not properly safeguarded.

Machinery accidents figure prominently in official accident statistics, and it is important to take steps to minimize the risks posed by machinery in the workplace. Proper training, maintenance, and safety procedures can help to reduce the likelihood of an accident occurring, and effective safeguards can help to protect workers from injury if an accident does occur. By taking these precautions, we can help to make the workplace safer for everyone. In this blog post, we will discuss common machinery hazards and control measures that can be taken to reduce the risk of injury.

Mechanical Safety

Mechanical Safety is the practice of protecting workers from exposure to potential mechanical hazards. In the United States, OSHA‘s Mechanical Safety standard (29 CFR 1910.219) requires that employers take steps to protect workers from exposure to moving parts of machinery and equipment.

Mechanical safety is important because it protects workers from injuries when exposed to moving parts of machinery and equipment. Injuries that can occur include cuts, bruises, and fractures. Employers can prevent these injuries by taking steps to protect workers from exposure to these hazards.

When assessing the risks associated with machinery, it is important to consider all potential hazards, both those that are always present and those that can appear unexpectedly. All phases of the machine life cycle need to be taken into account, including transport, assembly, and installation; commissioning; use; maintenance; dismantling, disabling, and scrapping. By considering all possible hazards, it is possible to develop a comprehensive risk management plan that will help to keep workers safe and minimize the possibility of accidents.

What Is Considered To Be Machinery?

Machinery generally refers to the machines that are used in industrial applications. These machines are usually powered by electricity and are used to perform various tasks in manufacturing and other industrial processes. Some examples of machinery include lathes, milling machines, drill presses, and injection molding machines.

Mechanical Machinery Hazards & Control Measures

There are many potential hazards associated with machinery. Some of these hazards are always present, while others can appear unexpectedly. It is important to be aware of all potential hazards in order to develop a comprehensive risk management plan.

The following are some common hazards associated with machinery:

1. Crushing Hazards

On construction sites, crushing hazards are often caused by excavators and other heavy machinery. If an employee is struck by a piece of machinery, it can result in serious injuries or even death. To prevent crushing hazards, employees should always be aware of their surroundings and stay clear of areas where heavy machinery is operating. If necessary, workers should wear personal protective equipment (PPE) to protect themselves from potential hazards.

Crushing hazards can also occur when workers are performing maintenance on machinery. If a worker is not properly trained in how to safely perform maintenance, they could be seriously injured or killed. To prevent these hazards, it is important for employers to provide employees with proper training and safety procedures.

2. Shear Hazards

Shear hazards are caused by moving parts that can cut or slice through skin and flesh. Shear hazards can occur when workers use hand-operated tools, such as knives, or when operating machinery with moving parts, such as saws.

Employees should always use the proper safety equipment and procedures when working with hand-operated tools or machinery to prevent shear hazards.

3. Cutting/Severing Hazards

There are many types of cutting hazards, but the three most common contact with a moving sharp-edged part, contact with a rotating part, and contact with a moving part.

The first type of cutting hazard is contact with a moving sharp-edged part. This can happen when you are using a machine with a blade, such as a bandsaw. If the blade is not properly guarded, your clothing or skin can come into contact with the blade and be cut.

The second type of cutting hazard is contact with a rotating part. This can happen when you are using a drill press or lathe. If the chuck or bit is not properly secured, your clothing or skin can come into contact with the rotating part and be cut.

The third type of cutting hazard is contact with a moving part. This can happen when you are using a power saw or drill. If the blade or bit is not properly secured, your clothing or skin can come into contact with the moving part and be cut.

To avoid these hazards, always make sure that the blades on your machines are properly guarded and that the chucks and bits on your drill presses and lathes are properly secured. If you are using a power saw or drill, make sure that the blade or bit is not worn or damaged. Also, always wear proper protective clothing, such as gloves, when using any type of machinery.

4. Drawing In Or Trapping Hazards

This hazard can occur when clothing or body parts become caught in moving parts of a machine. The result can be severe injuries or even death. To prevent this hazard, always make sure that you are wearing proper protective clothing, such as gloves and long sleeves when working with machinery. Also, keep your hands and feet away from moving parts and make sure that hair is tied back so that it cannot become caught in machinery.

5. Stabbing or Puncture Hazards

Stabbing or puncture hazards can occur when you are using a machine with a pointy or sharp edge, such as a drill press. If the bit is not properly secured, your clothing or skin can come into contact with the pointy or sharp edge and be punctured. To prevent this hazard, always make sure that the bit on your drill press is properly secured. Also, wear proper protective clothing, such as gloves, when using any type of machinery.

7. Friction or Abrasion Hazards

Friction and abrasion hazards are often found in mechanical machinery. When contact is made with a fastmoving surface that may be smooth (e.g. touching a spin dryer) or rough (e.g. touching a belt sander), there is a potential for serious injury.

There are several ways to protect yourself from these hazards:

• Wear appropriate Personal Protective Equipment (PPE), such as gloves, safety glasses, and ear protection.
• Be aware of your surroundings and stay clear of moving parts.
• Follow the manufacturer’s instructions for operating the machinery safely.

8. Entanglement Hazards

Entanglement hazards can occur when clothing or body parts become caught in moving parts of a machine. The result can be severe injuries or even death.

There are several ways to prevent this from happening:

• Keep your hair pulled back and away from rotating machine parts.
• Wear close-fitting clothes that won’t get caught on anything.
• Be aware of your surroundings and what you’re doing at all times.

If you see someone else caught in a machine, don’t try to help them yourself. Turn off the machine and get help from someone who knows how to safely release them.

Entanglement is a very real hazard in any industry that uses machinery. By taking some simple precautions, you can prevent it from happening to you or anyone else.

9. Impact Hazards

The most common type of impact hazard is when the body is struck by a powered part of a machine. This is similar to crushing, but there is no fixed structure to trap the person. The speed and weight of the object do the damage.

Impact hazards can also occur when two parts of a machine collide with each other. This can happen when two parts of a machine are not properly aligned, or when one part of a machine breaks and hits another part. Impact hazards can also occur when a person is hit by a flying object that has been thrown or ejected from a machine.

Impact hazards can be prevented by proper maintenance of machines, proper training of workers, and the use of safety devices. Impact hazards can also be minimized by the use of guards and barriers. When working with machines, it is important to be aware of the potential for impact hazards and to take precautions to avoid them.

10. High-pressure Fluid Injection Hazards

High-pressure fluid injection is a hazard that can occur when fluids are forced into the body at high pressures. This can happen when a person is cleaning a machine with high-pressure water and the nozzle breaks, or when a person is hit by a stream of high-pressure fluid from a ruptured hose. The high-pressure fluid injection can also occur when a person is welding and the arc flashes back, injecting molten metal into the body.

The high-pressure fluid injection can cause serious injuries or even death. Always use proper safety equipment when working with high-pressure fluids to prevent this hazard. Be sure to wear goggles or a face shield to protect your eyes, and wear gloves and protective clothing to protect your skin. If you are welding, be sure to wear a welding helmet to protect your face and neck.
