Welding Safety Chapter 2 Flashcards

Welding Safety Flashcards

• Acetone: A fragrant chemical that tints acetylene, which is ordinarily odorless.

• Acetylene: A fuel gas crucial for welding and cutting. It is unstable above 15 psig and produces one of the highest flame temperatures when burned in oxygen.

• Earmuffs: Designed to cover ears for protection against noise exceeding 90 dB.

• Earplugs: In-ear protection effective for shielding against noise levels above 90 dB.

• Electric Shock: Occurs when an individual contacts an electrical energy source, posing serious risk.

• Electrical Ground: Provides a direct connection to the earth, minimizing accidental contact with electrical hazards.

• Electrical Resistance: Measures the difficulty of electric current passing through a conductor. Larger surface area and diameter enhance current flow.

• Exhaust Pickups: Individual ventilation units that remove welding fumes efficiently.

• Flash Burn: An arc-caused injury primarily affecting the eyes from brief exposure to ultraviolet light during welding.

• Flash Glasses (Oxyfuel Goggles): Goggles with shaded lenses that protect against flash burns and retinal damage when using oxyfuel.

• Forced Ventilation: A system that forces air through ducts under pressure to ensure proper airflow.

• Full Face Shield: Protective gear that shields the entire face from impact hazards, such as debris and flying objects.

• Ground-Fault Circuit Interrupter (GFCI): A safety device that shuts off electricity if it detects current flowing through an unintended path, preventing shocks.

• Goggles: Eye protection against liquid splashes, acid vapors, airborne dust, and impact threats.

• Infrared Light: Produces heat and poses hazards in oxyfuel cutting and welding by causing bone marrow to expand.

• Natural Ventilation: Utilizes natural air movement for ventilation without mechanical assistance.

• Safety Data Sheets (SDS): Documents detailing potential health risks from chemical exposure and guidelines for safe handling of hazardous materials.

• Safety Glasses: Toughened eyewear that safeguards the eyes during the use of power tools or in industrial settings.

• Type A Fire Extinguisher: Effective against common combustible fires involving materials like wood and paper, excluding flammable liquids and electrical fires.

• Type B Fire Extinguisher: Designed for fires from combustible liquids such as oil or gasoline, without electrical involvement.

• Type C Fire Extinguisher: Used for fires involving electrical equipment, preventing shocks.

• Type D Fire Extinguisher: Specifically for extinguishing fires caused by combustible metals like magnesium.

• Ultraviolet Light: Harmful rays that can damage the eyes, potentially leading to corneal issues, cataracts, and skin cancer in the eye area.

• Valve Protection Cap: Safety caps that must remain on gas cylinders when not in use to ensure safe transportation.

• Ventilation: A mechanical system that circulates fresh air in a room or building, essential for a safe working environment.

• Visible Light: A form of electromagnetic radiation that encompasses wavelengths visible to the human eye, part of a broader spectrum that includes various radiation types.
