PTS Protective Equipment (PPE) 3 — Questions and Answers
Question 1: What is the primary purpose of anti-vibration gloves used during track tamping operations?
- To improve grip on tamping tools
- To reduce exposure to hand-arm vibration syndrome (HAVS) (Correct answer)
- To protect against electrical shock
- To prevent blisters from prolonged tool use
Correct answer: To reduce exposure to hand-arm vibration syndrome (HAVS)
Anti-vibration gloves are designed to attenuate vibration transmitted from power tools to reduce the risk of hand-arm vibration syndrome (HAVS), also known as vibration white finger.
Question 2: Which hard hat class is required when working near overhead electrical hazards up to 20,000 volts?
- Class A
- Class B (Correct answer)
- Class C
- Class G
Correct answer: Class B
ANSI Class B hard hats provide protection against high-voltage electrical conductors up to 20,000 volts and are required near electrical hazards on the right-of-way.
Question 3: A worker notices their co-worker's high-visibility vest is faded and the retroreflective strips are peeling. What should happen?
- The vest can remain in use until the end of the project
- The co-worker should tape the strips back down
- The vest must be replaced before the worker re-enters the track zone (Correct answer)
- The vest is acceptable as long as it is still visible during daytime
Correct answer: The vest must be replaced before the worker re-enters the track zone
Damaged or degraded high-visibility vests no longer meet retroreflectivity standards and must be replaced before the worker enters any active rail corridor.
Question 4: Which eye protection is required when using a grinder on rail welds?
- Safety glasses with side shields only
- Face shield worn over safety glasses (Correct answer)
- Tinted sunglasses with UV protection
- Standard prescription glasses
Correct answer: Face shield worn over safety glasses
Grinding operations generate high-velocity sparks and metal fragments requiring both a face shield for splash protection and safety glasses as backup eye protection.
Question 5: What is the correct storage practice for a hard hat when not in use?
- Store in direct sunlight to keep it dry
- Store in the rear window shelf of a vehicle for easy access
- Store away from UV light, chemicals, and extreme heat (Correct answer)
- Hang it on a hook by the suspension harness
Correct answer: Store away from UV light, chemicals, and extreme heat
Hard hat shells degrade from UV radiation, chemical exposure, and heat, so they should be stored in a cool, dry location away from direct sunlight.
Question 6: Fall protection PPE is required on the track when workers are at risk of falling from a height of how many feet or more?
- 4 feet
- 6 feet (Correct answer)
- 10 feet
- 15 feet
Correct answer: 6 feet
OSHA's general industry and construction standards require fall protection when workers are exposed to fall hazards of 6 feet or more.
Question 7: A worker's safety boots have oil-soaked soles from track maintenance work. What is the primary hazard?
- Reduced electrical insulation
- Increased slip hazard on rail surfaces and ballast (Correct answer)
- Loss of steel-toe impact protection
- Accelerated chemical breakdown of the boot upper
Correct answer: Increased slip hazard on rail surfaces and ballast
Oil-contaminated soles dramatically reduce traction, increasing the risk of slips and falls on rail, ties, and ballast—one of the leading causes of track worker injuries.
