Objective
To understand the importance of machine guarding, identify hazards, and implement control measures to prevent injuries.
Introduction
Machine guarding is essential for protecting employees from injuries caused by moving machine parts. Guards are designed to protect you from numerous dangers, including moving or sharp machine parts, flying sparks or particles, and hot surfaces. [5]
Hazard Identification
Identifying potential hazards associated with machinery is the first step in preventing accidents.
- Unguarded moving parts (gears, sprockets, pulleys, flywheels, rotating parts).: Contact with moving parts can cause cuts, amputations, crushing injuries, or death. [2] [2]
- Point of operation hazards (cutting, bending, drilling, punching).: Injuries such as cuts, lacerations, amputations, or punctures. [3]
- Flying chips, sparks, or ejected materials.: Eye injuries, skin lacerations, or burns. [5]
- Electrical hazards (ungrounded equipment, loose wiring).: Electric shock, electrocution, or burns. [1] [1]
- Ergonomic hazards (awkward posture, repetitive motion, excessive force).: Musculoskeletal disorders (MSDs) such as strains, sprains, or carpal tunnel syndrome. [7]
Control Measures
- Install and maintain machine guards.: Ensure guards are firmly secured, prevent contact with moving parts, and do not create additional hazards. [2] [2]
- Use lockout/tagout procedures.: De-energize and lock out machinery before maintenance or repairs. [5]
- Provide and use appropriate PPE.: Wear safety glasses, gloves, and other PPE as required.
- Ensure proper lighting and housekeeping.: Maintain adequate lighting and keep work areas clean and free of slip and trip hazards.
- Provide comprehensive training.: Train operators and maintenance personnel on safe operating procedures, hazard recognition, and control measures. [1] [1]
- Regularly inspect machinery and guards.: Conduct routine inspections to identify and correct any deficiencies. [3]
Personal Protective Equipment (PPE) Requirements
- Safety Glasses: Always wear safety glasses or face shields to protect against flying particles, sparks, and debris. Ensure they meet ANSI Z87.1 standards.
- Gloves: Wear appropriate gloves to protect against cuts, abrasions, and chemical exposure. Select gloves based on the specific task and materials being handled. [6]
- Hearing Protection: Use earplugs or earmuffs in areas with high noise levels to prevent hearing damage.
- Protective Clothing: Avoid loose-fitting clothing or jewelry that could get caught in machinery. Wear appropriate work attire, such as long sleeves and pants, to protect against cuts and abrasions. [4]
Group Discussion

- What are the common machine guarding hazards in our workplace?
- How can we improve our machine guarding practices?
- What should you do if you notice a damaged or missing machine guard?
Emergency Procedures
- Immediately stop the machine.
- Report the incident to your supervisor.
- Seek medical attention for any injuries.
Summary
Recap of main points:
- Machine guarding is crucial for preventing injuries.
- Always use machine guards and safety devices.
- Report any hazards or equipment malfunctions immediately.
- Follow lockout/tagout procedures when performing maintenance.
Report all hazards, near-misses, and incidents to your supervisor immediately.
