Question 1

A welder is working overhead and a piece of hot slag falls into their boot. What PPE would have prevented this injury?

Accepted Answer

Boot covers or spats

Answer

Boot covers or spats (leather or FR fabric) wrap around the boot top to prevent hot spatter and slag from entering the boot.

Question 2

What is the primary purpose of a welding curtain or screen in a shared workspace?

Accepted Answer

To protect bystanders from arc flash and UV radiation

Answer

Welding curtains are made of UV-opaque material specifically to shield nearby workers from harmful arc radiation and flash burns.

Question 3

According to OSHA 1910.252, when is general ventilation alone considered adequate for arc welding?

Accepted Answer

When base metal coatings are non-toxic and the work area is open

Answer

General ventilation is adequate only when the area is large enough, the room air movement is sufficient, and no toxic coatings or base metals are involved.

Question 4

Which lens shade is typically recommended for shielded metal arc welding (SMAW) at 200–400 amperes?

Accepted Answer

Shade 12

Answer

AWS recommends shade 12 for SMAW operations in the 200–400 ampere range to provide adequate protection against arc radiation.

Question 5

What type of glove is most appropriate for TIG (GTAW) welding compared to SMAW?

Accepted Answer

Thinner, more flexible gloves for dexterity and heat sensitivity

Answer

TIG welding requires precise finger control to feed filler rod, so thinner, supple gloves are preferred over the heavy gauntlets used in SMAW.
