SAW Safety Systems & Standards 2

Question 1

Which ANSI/AWS standard specifically governs safety in welding, cutting, and allied processes?

Accepted Answer

ANSI/AWS Z49.1

Answer

ANSI/AWS Z49.1 is the primary safety standard covering welding, cutting, and allied processes including SAW.

Question 2

When performing SAW near combustible materials, the minimum safe clearance distance required is:

Accepted Answer

25 feet (7.6 m)

Answer

ANSI/AWS Z49.1 requires a minimum 25-foot (7.6 m) clearance from combustibles, or appropriate fire-resistant shields must be used.

Question 3

A flux recovery system on a SAW unit that recirculates flux without screening poses which primary hazard?

Accepted Answer

Reintroduction of contaminated or slag-included flux into the weld pool

Answer

Unscreened recycled flux can contain slag particles that cause weld defects and trap harmful gases, compromising both weld quality and operator safety.

Question 4

Which type of fire extinguisher is most appropriate for an electrical fire involving SAW equipment?

Accepted Answer

Class C (CO2 or dry chemical)

Answer

Class C extinguishers are rated for energized electrical equipment and will not conduct electricity back to the operator.

Question 5

What is the purpose of an interlocking safety guard on a SAW wire feeder's drive rolls?

Accepted Answer

To de-energize the feeder when the guard is opened, preventing crush injuries

Answer

Interlocking guards automatically cut power to drive rolls when opened, protecting fingers and hands from the pinch-point hazard.
