Acetylene

A fuel gas used in welding and cutting. It's unstable above 15 psig and burns very hot with oxygen.

Acetone

A fragrant chemical that is added to acetylene to give it a smell. Acetylene is normally odorless.

Earmuffs

Headphones that cover your ears to protect you from loud noises over 90 decibels.

Earplugs

In-ear protection that blocks loud sounds over 90 decibels.

Study Notes

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.
