If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines.
Can welding start fires?
The sparks and expulsion of molten metal produced by welding and cutting processes are ready sources of ignition that can travel up to 35 feet (10 meters) from their source. Because sparks can travel so far, any combustible material in the immediate area can pose a significant fire hazard.
How long after welding can a fire start?
A fire watch shall be maintained for
at least a half hour
after completion of welding or cutting operations to detect and extinguish possible smoldering fires.
How do you prevent welding fires?

Are welding sparks hot?
At such high temperatures, the molten metal bubbles and spits, expelling a shower of incandescent droplets: these are the sparks you see. They can be

Is it safe to weld in a garage?

not wearing the right PPE
. Arc welding produces sparks and spatter — and emits intense rays that pose several hazards to unprotected skin and eyes. Shorts, short sleeves and open collars leave you vulnerable to burns.
Is it safe to weld near wood?
Wood is a highly-flammable material that must be covered with the
appropriate nonflammable material prior
to welding. Utilizing a fire watcher is another alternative for instances where welding cannot be removed from an area with considerable flammable materials.
What kind of fire extinguisher do welders need?
For most welding, a
combination extinguisher (Class A, B, C)
is best. ➢ For magnesium fires, it is best to use a Class D fire extinguisher or to cover the fire with sand or magnesium foundry flux.
How do welders stay healthy?
Cardiovascular exercises, such as
running, swimming or cycling
, can help you build endurance for long days on the job by strengthening your heart and lungs. Though you'll be wearing a respirator when ventilation is inadequate, it's important to avoid respiratory problems in tight, dusty, and fume-filled spaces.
Why do welders have explosions?
Using an explosion,
one piece of metal is accelerated at high velocity towards another
. Their impact results in a solid state bond between the pieces, successfully welding them together.
Is welding a good career?
Welding is an excellent career
, and welders commonly praise their profession and extol the many benefits they get from welding as a career. Overall, if you can handle extreme conditions, long hours, and smoke and fire regularly, a career in welding can be rewarding.
What kind of welding makes sparks?
MIG welding
is called metal inert gas welding. MIG uses a welding gun with a feed wire. The feed wire transmits an electrical current which then creates the sparks. This electrical current/sparks is what heats the metal and melts it.
Do welding sparks hurt?
The immediate danger welders is the danger of burns on the body:
Sparks can fly into shoes or eyes and cause injury
. To protect the body from sparks, welders should wear high-necked, low flammability protective clothing, leather protective gloves and a welding helmet.
