Which personal protective equipment is REQUIRED when chipping slag from a completed weld?
Answer: Face shield or safety glasses with side shields
Chipping slag propels hot particles at high velocity, requiring at minimum safety glasses with side shields or a full face shield to protect against eye and face injuries.
What is the function of a 'dead-man' or anti-restart device on an automatic welding machine?
Answer: It prevents the machine from restarting after a power interruption without operator action
An anti-restart (dead-man) device prevents automatic equipment from restarting unexpectedly after a power failure, protecting operators from sudden uncontrolled motion or arc initiation.
When welding in a confined space, which atmospheric condition must be continuously monitored per OSHA 29 CFR 1910.146?
Answer: Oxygen level, flammable gas concentration, and toxic contaminants
OSHA's permit-required confined space standard mandates continuous monitoring of oxygen levels (19.5–23.5% acceptable range), flammable gas concentrations, and toxic air contaminants throughout the welding operation.
What is the correct storage position for compressed gas cylinders when not in use?
Answer: Standing upright and secured with a chain or strap
Compressed gas cylinders must be stored upright and secured with a chain, strap, or rack to prevent tipping, and valve caps must be in place when not connected to regulators.
Which of the following is an example of an engineering control (not PPE) used to reduce welder fume exposure?
Answer: Local exhaust ventilation (LEV) at the source
Local exhaust ventilation captures fumes at the source before they reach the welder's breathing zone, making it an engineering control higher on the hierarchy of controls than PPE.
A welder receives an electric shock and is unresponsive. What is the correct FIRST action by a bystander?
Answer: Disconnect power or use a non-conductive object to break contact before touching the victim
Before touching a victim of electrical shock, the power source must be disconnected or the victim freed using a non-conductive material to avoid secondary electrocution of the rescuer.
What does the Safety Data Sheet (SDS) Section 8 specifically provide for welding filler metals?
Answer: Occupational exposure limits and recommended PPE
SDS Section 8 (Exposure Controls/Personal Protection) lists OSHA PELs, ACGIH TLVs, and the recommended respiratory protection, gloves, and eye protection for the product.
