SECTION 1: SAFETY AND PERSONAL PROTECTIVE EQUIPMENT (Questions 1-60)
Question 1: Which OSHA standard specifically addresses welding, cutting, and brazing safety?
A) 1910.1200
B) 1910.252
C) 1910.94
D) 1910.107
Answer: B) 1910.252
Rationale: OSHA 1910.252 outlines the specific safety requirements for welding, cutting, and
brazing operations, including fire prevention, ventilation, and personal protective equipment .
Question 2: What is the primary function of the lens in a welding helmet?
A) To magnify the weld pool for better visibility
B) To protect the welder's eyes from infrared and ultraviolet radiation
C) To provide a tint that reduces overall brightness
D) To allow the welder to see through smoke and fumes
Answer: B) To protect the welder's eyes from infrared and ultraviolet radiation
Rationale: The lens's main purpose is to filter out harmful UV and IR radiation produced by the
arc, which can cause eye damage like arc flash. While it reduces brightness, the primary function
is radiation protection .
Question 3: According to OSHA standards, what is the minimum recommended distance for
storing oxygen cylinders away from fuel gas cylinders?
A) 5 feet
B) 10 feet
C) 20 feet
D) 30 feet
Answer: C) 20 feet
, Rationale: OSHA requires a minimum separation of 20 feet between stored oxygen and fuel gas
cylinders, or a non-combustible barrier at least 5 feet high with a 30-minute fire rating .
Question 4: When moving a compressed gas cylinder, the welder should always:
A) Roll it on its side
B) Use a cylinder cart and keep the cap on
C) Lift by the valve
D) Drag it across the floor
Answer: B) Use a cylinder cart and keep the cap on
Rationale: Cylinders must be moved upright with caps and carts for safety. Rolling cylinders or
lifting by the valve can cause damage and serious injury .
Question 5: Which welding hazard is most directly associated with UV radiation from the arc?
A) Heat cramps
B) Eye and skin damage
C) Back strain
D) Noise-induced hearing loss
Answer: B) Eye and skin damage
Rationale: UV light from welding arcs can burn eyes and skin. This is why proper eye
protection (shade lenses) and protective clothing are mandatory .
Question 6: A Class A fire extinguisher can be safely used on which type of fire?
A) Electrical
B) Wood, paper, cloth
C) Flammable liquids
D) Metal
Answer: B) Wood, paper, cloth
Rationale: A Class A fire extinguisher is appropriate for use only on regular combustible
materials such as wood, paper, cloth, etc. .
Question 7: Lockout/tagout procedures are primarily used to:
A) Store tools
B) Prevent unexpected energizing of equipment during maintenance
