Welding Safety Flashcards

Essential vocabulary for welding safety based on lecture notes for Introduction to Welding & Metallurgy.

Welding Hazards

Common risks in welding including burns, arc flash, fire, explosions, fumes, and electrical shock.

PPE (Personal Protective Equipment)

Specialized gear, like welding helmets, safety glasses, and flame-resistant clothing, worn to protect welders from hazards.

Welding Helmet

Eye and face protection with a proper lens shade (e.g., #10+) for arc welding.

Safety Glasses

ANSI Z87.1 approved eyewear required to be worn at all times in the shop.

Flame-Resistant (FR) Clothing

Garments such as long-sleeve shirts, welding jackets, and leather aprons designed to resist burning.

Prohibited Clothing Materials

Polyester, nylon, or synthetic materials; they can melt onto skin when exposed to heat or sparks.

Leather Welding Gloves

Essential hand protection for welders.

Earplugs

Hearing protection used when grinding or around loud equipment.

Spark Travel Distance

Sparks from welding can travel up to 35 feet.

Fire Watch

A designated person or procedure required if welding near flammable materials to prevent fires.

Class A Extinguisher

Type of fire extinguisher used for fires involving ordinary combustibles like wood, paper, and cloth.

Class B Extinguisher

Type of fire extinguisher used for fires involving flammable liquids or gases.

Class C Extinguisher

Type of fire extinguisher used for fires involving electrical equipment.

ABC Dry Chemical Extinguisher

The most versatile fire extinguisher, effective for Class A, B, and C fires.

PASS Method

An acronym for using a fire extinguisher: Pull, Aim, Squeeze, Sweep.

Oxygen Cylinder

An oxy-fuel gas cylinder typically colored green.

Acetylene Cylinder

An oxy-fuel gas cylinder typically colored red.

Acetylene Pressure Limit

Never exceed 15 psi for acetylene gas.

Torch Lighting Sequence

Open acetylene valve slightly first, ignite with a spark lighter, then slowly add oxygen.

Torch Shutting Rown Sequence

Close acetylene first, then oxygen, and finally close cylinder valves after use.

Leak Check (Oxy-Fuel)

Method of detecting gas leaks using soapy water on connections.

Electrical Shock

A potential fatal hazard caused by welding current, preventable by wearing dry gloves and avoiding wet conditions.

Lockout/Tagout

A safety procedure used to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or servicing work.

Welding Fumes

Airborne particles and gases produced during welding that can cause lung and other health problems.

Toxic Fumes Metals

Certain metals, such as zinc, lead, cadmium, and beryllium, that create harmful fumes when welded.

Metal Fume Fever

A flu-like illness resulting from exposure to metal fumes, with symptoms like dizziness, nausea, and headaches.

Ventilation

The circulation of air or use of exhaust hoods to remove welding fumes from the work area, especially indoors.

Welding on Closed Containers

Extremely dangerous practice due to the high risk of explosion.

Arc Flash (Welder's Flash)

An eye burn caused by intense UV rays from the welding arc.

Radiation Exposure (Welding)

Damage to skin and eyes from UV/IR radiation emitted by the welding arc.

Lifting Technique

Proper method for lifting heavy objects by bending the knees, not the back, to prevent injury.

Fatigue

Physical or mental exhaustion that increases the risk of accidents in the workplace.
