Vibration Safety Questions and Answers
General Vibration Safety Knowledge
- Q: What is vibration in the workplace?
- A: Vibration is the oscillation or movement of machinery, equipment, or surfaces that workers are exposed to, which can lead to health risks if prolonged or excessive.
- Q: What are the main types of vibration in the workplace?
- A: The two main types are hand-arm vibration (HAV) and whole-body vibration (WBV).
- Q: What is hand-arm vibration (HAV)?
- A: Hand-arm vibration refers to vibrations transmitted into the hands and arms, often from power tools and machinery.
- Q: What is whole-body vibration (WBV)?
- A: Whole-body vibration is the transmission of vibrations to the whole body, typically from heavy machinery, vehicles, or equipment that workers operate.
- Q: Why is vibration safety important in the workplace?
- A: Exposure to excessive vibration can lead to serious health issues like nerve damage, circulatory problems, musculoskeletal disorders, and reduced comfort or safety.
Health Effects of Vibration Exposure
- Q: What are the health effects of hand-arm vibration (HAV)?
- A: Health effects of HAV include conditions like Hand-Arm Vibration Syndrome (HAVS), which affects blood vessels, nerves, and joints in the hands and arms.
- Q: What is Hand-Arm Vibration Syndrome (HAVS)?
- A: HAVS is a condition caused by regular and frequent exposure to hand-arm vibration. It results in symptoms such as numbness, tingling, loss of grip strength, and blanching of fingers.

- A: Engineering controls include installing vibration dampers, isolating vibration sources, using vibration-reducing equipment, and designing equipment with reduced vibration characteristics.
Personal Protective Equipment (PPE) for Vibration Safety
- Q: How does personal protective equipment (PPE) help in vibration safety?
- A: PPE, such as vibration-reducing gloves and padded seat cushions, helps to minimize the transmission of vibrations to workers’ bodies, reducing the risk of injury.
- Q: What type of gloves should be used to protect against hand-arm vibration?
- A: Vibration-dampening gloves with an anti-vibration lining or padding are designed to absorb and reduce vibration exposure to the hands and arms.
- Q: How effective are vibration-damping gloves in preventing HAVS?
- A: While they can reduce the intensity of vibration exposure, vibration-damping gloves do not completely eliminate the risk of HAVS if exposure is excessive or prolonged.
- Q: How can workers protect themselves from whole-body vibration (WBV)?
- A: Workers can use ergonomic seating, wear padded seat cushions, and ensure proper posture to minimize WBV exposure when operating machinery or vehicles.

- A: In addition to gloves and seat cushions, workers may use vibration-reducing mats, ergonomic handles, and anti-vibration tools.
Vibration Safety Training
- Q: Why is vibration safety training important?
- A: Vibration safety training helps workers understand the risks of vibration exposure, how to use equipment safely, and the importance of using protective equipment.
- Q: What topics should be covered in vibration safety training?
- A: Training should include information on vibration hazards, symptoms of vibration-related health issues, proper use of PPE, safe handling of vibrating equipment, and the importance of regular breaks.
