SECTION 1: SAFETY & PERSONAL PROTECTIVE
EQUIPMENT
1. 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
CORRECT ANSWER: B – 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.
,2. 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
CORRECT ANSWER: C – 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.
3. What is the most important safety equipment used in arc welding?
A) Clothing
B) Leather gloves
C) Welding helmet
,D) Electrode holder
CORRECT ANSWER: C – The welding helmet provides essential
protection for the eyes and face against arc radiation (UV/IR),
sparks, and debris. Eye protection is the most critical safety
consideration in arc welding.
4. A Class A fire extinguisher can be safely used on which type of
fire?
A) Wood
B) Grease
C) Electrical
D) Flammable liquids
CORRECT ANSWER: A – Class A fire extinguishers are designed
for ordinary combustibles such as wood, paper, and cloth. Class B is
for flammable liquids, Class C for electrical fires, and Class D for
combustible metals.
5. What does the acronym PPE stand for in welding safety?
, A) Personal Protective Equipment
B) Primary Protection Equipment
C) Professional Practice Equipment
D) Personnel Performance Equipment
CORRECT ANSWER: A – PPE stands for Personal Protective
Equipment, which includes helmets, gloves, safety glasses, ear
protection, and protective clothing worn to minimize exposure to
workplace hazards.
6. 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
