Why Is Machine Guarding Important for Workplace Safety?

Machines have moving parts that enable productivity but also pose risks for workplace injuries. Potential injuries include amputations, crushed fingers and hands, blindness, and burns. To ensure worker safety, OSHA sets safety standards for machine guarding. Failure to comply with these standards can result in serious penalties. Here are a few examples of companies that have violated machine guarding regulations:

  • A manufacturing plant faced a penalty of $136,532 after a worker suffered an amputation injury due to lack of proper machine guards.
  • At an auto parts manufacturer, OSHA discovered no machine guarding in place after investigating an arm injury. Proposed penalties totaled $205,384.
  • OSHA found problems with machine guarding and lockout/tagout procedures after a worker’s death at an aluminum parts manufacturer. The total proposed penalties amounted to $1,671,738.

Implementing machine guarding as part of a comprehensive EHS program can mitigate risks, reduce losses, lower workers compensations insurance premiums, and prevent personal loss to employees.

Types of Machine Guards

Machine guards come in different types based on their functionality and the hazards they protect operators from. Here are the four types identified by OSHA:

  • Fixed guards: These are permanently attached to machines and enclose hazardous areas. They include gates, fences, barriers, or blade covers.
  • Adjustable guards: Also permanently attached, they have moving parts that can be manually adjusted. Operators need expertise to use them correctly.
  • Self-adjusting guards: Similar to adjustable guards, but they automatically adjust when operators work on dangerous parts of machines.
  • Interlocked guards: These have movable parts that cut off power or shut down the machine when tampered with and are used at points leading to the machine’s interior.

There are also three main types of machine guards based on the hazards they protect operators from:

  • Point-of-operation guards: Designed to keep operators safe while working on machines. Examples include guards for power saws and power presses.
  • In-running point guards: These protect against amputations caused by parts rotating against each other, such as gears.
  • Flying chips and spark guards: Used in procedures like grinding or welding to protect against projectiles and sparks. For example, welding protective covers.

OSHA Requirements for Machine Guarding

OSHA requires that one or more methods of machine guarding be provided to protect operators and employees from various hazards. Here are some key requirements:

  1. All machine points of operation must be guarded.
  2. Hand tools must be easy to use without exposing operators to risk.
  3. Fan blades must be guarded if their outer edges are less than seven feet above the workspace.
  4. All guards must be well secured and actively protect operators from all types of injuries.
  5. Every part of a machine that can be guarded must be guarded.
  6. All guards must be in working order and appropriate for practical use.
  7. Guards must not create new potential hazards.
  8. The guards should not interfere with normal working procedures.

OSHA also recommends that machines allow for lubrication with the guards remaining in place.

Violating OSHA’s machine guarding requirements can result in fines totaling hundreds of thousands of dollars. It is crucial to train operators on the proper use and maintenance of machine guards to ensure their effectiveness in keeping workers safe.
