G60 Personal Protective Equipment and Work Area Setup 1 — Questions and Answers
Question 1: What shade of lens filter is typically required for torch brazing and light cutting operations?
- Shade 3 to 5 (Correct answer)
- Shade 10 to 12
- Shade 1 to 2
- Shade 8 to 9
Correct answer: Shade 3 to 5
OSHA and ANSI standards recommend shade 3 to 5 filter lenses for torch brazing and light gas cutting to protect eyes from infrared radiation and sparks.
Question 2: Why must synthetic clothing be avoided when performing torch operations?
- Synthetics melt onto skin when ignited, causing severe burns (Correct answer)
- Synthetics reduce visibility in the work area
- Synthetics create static electricity that can ignite gas
- Synthetics are not durable enough for industrial use
Correct answer: Synthetics melt onto skin when ignited, causing severe burns
Synthetic fabrics like polyester and nylon melt at low temperatures and adhere to skin when ignited, dramatically worsening burn injuries compared to natural fibers.
Question 3: Which gloves are appropriate for torch use with flammable gases?
- Leather welding gloves (Correct answer)
- Thin latex or nitrile gloves
- Standard work gloves with rubber grip
- No gloves — they reduce dexterity
Correct answer: Leather welding gloves
Leather welding gloves provide heat resistance and protection from sparks and hot metal during torch operations — thin or rubber gloves will not protect against these hazards.
Question 4: What footwear is required when performing torch operations?
- Leather work boots with no exposed lace hooks or open tops (Correct answer)
- Standard sneakers or athletic shoes
- Open-toed sandals with heat-resistant soles
- Rubber boots for electrical protection
Correct answer: Leather work boots with no exposed lace hooks or open tops
Leather work boots protect feet from sparks and falling hot metal; boots should have no exposed metal hooks that can catch sparks and no openings for hot debris to enter.
Question 5: When must a fire watch be posted during torch operations under NYC fire code?
- Whenever torch work is performed in an area where combustibles cannot be fully removed or shielded (Correct answer)
- Only when working above the 10th floor of a building
- Only during nighttime operations
- Fire watch is only required for electric arc operations, not torch work
Correct answer: Whenever torch work is performed in an area where combustibles cannot be fully removed or shielded
NYC fire code requires a fire watch whenever hot work including torch operations is done in areas where combustibles are present and cannot be adequately cleared or protected.
Question 6: What is the primary purpose of a welding curtain or screen around a torch work area?
- To protect bystanders from sparks, spatter, and UV/IR radiation (Correct answer)
- To contain the gas cylinders securely
- To improve lighting conditions for the operator
- To prevent wind from affecting the torch flame
Correct answer: To protect bystanders from sparks, spatter, and UV/IR radiation
Welding curtains shield nearby workers and bystanders from flying sparks, molten spatter, and the harmful ultraviolet and infrared radiation produced by torch operations.
