Welding Safety Flashcards
There are eight personal factors that may cause or contribute to accidents.
Stress Illness Fatigue Lack of Job Knowledge Age Lack of Wisdom Poor Attitude Drugs
There are three physical factors responsible for or involved in shop accidents.
Equipment Failure
Time of Day
HouseKeeping
What are the three most important factors in safety on the job?
- Staying healthy in mind and body
- Becoming well-trained in the required job or task and its possible hazards involved
- having a good attitude toward safety rules, equipment, and training on the job.
What is the responsibility and mandate of the US government agency OSHA
Oversees safety regulations in the workplace
Electric shock and kill, what are some of the factors to consider.
Wetness
Welder in or on workpiece
Confined space
Electrode holder and cable insualtion
Fumes and gases can be dangerous, what are some factors to consider?
Confined space
Positioning of welders head
Lack of general ventilation
Electrode types, chromium, manganese, etc.
Base metal coatings, galvanized, paint, etc.
Arc Rays can burn eyes and skin. What process has the most severe arc rays?
Gas-Shielded
When dealing with a confined space what are some factors to consider?
Metal enclosure Wetness Restricted entry Heavier than air gases Welder inside or on workpiece
General work area hazards and factors to consider
Cluttered work area
Electrical equipment
Engine-driven equipment
Gas cylinders
Personal Protective Equipment (PPE) list at least eight items of PPE
safety glasses hearing protection welding hood welding gloves Work boots Jeans Work shirt Any safety equipment (safety harness) etc.
Why do you not want to wear synthetic type of clothing when welding
When synthetic clothing catches on fire it will melt and stick to the skin causing severe burns.
Welding gloves are worn to protect against what types of injuries?
Arc radiation
Flames
Sparks
Hot flames or sharp metal
Housekeeping is one of the most important factors in shop safety, what does this really mean?
The floors, workbenches, equipment should be kept clean of dirt, scrap metal, gtrease, oil, DRINK BOTTLES, and anything that is not essential to the job at hand.
Combustibles, should be kept clear of (what?) and where should it be stored
must be kept clear of all areas where sparks or hot metal may fly. examples of combustibles would be wood, cardboard, paper, rags, flammable liquids, hair :)
etc.
True or False
Shops should normally have high ceilings for greater air volume and should have a well-designed ventilation system to provide an adequate volume of air-movement
TRUE
If your work area has hazards or obstacles what should be done so workers are fully aware of them?
These should be well marked by signs, fences, or barriers for temporary hazards, if you have permanent hazards they should be marked by wide yellow and black stripes to create high visibility
What information does a SDS supply
A SDS is a document that provides crucial information about a chemical or substance used in the workplace
Who prepares an SDS?
The manufacturer of the chemical or product
What standard must a SDS meet?
Must meet the OSHA Hazard Communication Standard (HCS)
What information does a SDS supply about the chemical or product that it is written up for?
The SDS will clearly explain the product identity, a listing of all hazardous ingredients and chemicals in the product, physical data, reactivity data, health hazard data, fire and explosion data, precautions for safe handling, as well as known health effects, symptoms, first aid treatment for exposure.
There are two ways that a employee can access a SDS what are they?
Electronic copy or paper copy
An oxyfuel gas flame is generally safe, but (blank) can build up to dangerous levels in a poorly ventilated place.
Carbon Monoxide (CO)
Why are inert gases dangerous to use in confined spaces?
Inert gases will displace air and oxygen
Do air purifying respirators filter out toxic fumes?
No, they are designed to only filter out dust, dirt, and metal fumes.
Your welding hood should have a sticker or stamp on the inside of it that reads CSA Z94.3, what does this mean
This standard relates to eye and face protectors for the industrial and educational processes.
There are two types of air respirators what are they?
Positive air flow respirator
Negative air flow respirator
How does a positive air flow respirator work?
The clean air flows from a central source or a special compressed air tank through a flexible hose into the welders helmet
How does a negative air respirator work
This removes dust and other airborne particles by drawing the contaminated air through a filter or cartridge in the respirator.
Cylinders like acetylene and Oxygen and other high pressure gases should be stored in an horizontal or vertical position?
Vertical
Acetylene gas must never be used at a working pressure on the gauge above ( blank ) psi
15
When you finish cutting with oxy/acetylene you should bleed the system down, how is this done?
All gases are bled from the cylinder to the torch tip, This is done by closing both cylinder tank valves, opening the torch valves, and turning in the regulator adjusting screw until all gases are released and the gauges read zero. The torch valves are then closed and the regulator adjusting screws are turned out unitl they feel loose.
What is the job of a fire watch
The fire watch is a person who carefully watches for fires that may start in the area where the welding or cutting is done.
What one item must every fire watch have and be trained to use?
Fire Extinguisher
What types of materials does a type A fire consist of?
Wood, Paper, Textiles
What types of materials does a class B fire consist of?
Grease, Gasoline, Oils, Paints.
What types of materials does a class C fire consist of?
Electrical equipment (motors, switches)
What types of materials does a class D fire consist of?
Magnesium, Lithium etc.
What type of fires do A extinguishers put out?
Solid material fires, these extinguishers are marked with a green triangle with an A in the middle of it
What type of fires do B fire extinguishers put out?
Combustible liquid, these have a red square sticker with a B in the middle of them.
What type of fires do C fire extinguishers put out?
Electrical fires and have a blue circle sticker with a letter C in the middle
What type of fires do D fire extinguishers put out?
Combustible metal fires, it has a yellow star sticker with a D in the middle
The National Fire Protection Association considers Welding and Cutting what type of work?
HOT
When you need a hot work permit who do you get one from?
Company’s safety department if the work being done is on company property
In other instances, the permit is obtained from the local fire department
A safety inspection of your welding area should be performed when?
Everytime you get ready to use your welding equipment
What does a safety check of your welding booth intel on your part as the welder.
detect damage to the equipment
any unsafe conditions
cable connectors are tight
welding gun should be checked for cracked insulators, loose contacts, worn out hoses
What is the most common injury encountered in the welding or cutting processes?
Burns
What causes burns to a welder while welding?
Ultraviolet or infrared rays
hot metal/sparks
What is a first degree burn? What first aid should be used on this?
A first degree burn occurs on the outer surface of the skin, First aid for this of burn is the application of cold water or cold water compresses to the burn area
What is a second degree burn? How is first aid applied to this?
With a second degree burn, the surface of the skin is severely damages, with small breaks in the skin and blisters appearing on the surface.
First aid for a second degree burn involves applying cold (not freezing) water and cold water compresses, the burn area is then covered with sterile bandages or pads, A doctor should be seen for further treatment.
What is a third degree burn? What first aid should be applied to this?
A third degree burn is the most serious. The surface of the skin appears white or charred like burned meat. The third or deeper layer of the skin may also be severely damaged with nerve and blood vessel damage.
NO water or ice should be placed on a third-degree burn area. Also No clothes should be removed from the burned area of the body. DO NOT put ointment, antiseptics, or any home remedies on the burn. Seek medical attention ASAP!
