General Safety, Welding

1- Never look at or cause another person to look at a weld being performed unless the proper safety equipment is protecting everyone’s eyes.

·                     Number 5 lens for oxy-fuel welding and cutting.

·                     Number 8 lens for plasma arc cutting.

·                     Number 10 to 12 for GMAW, SMAW and GTAW.

·                     Number 15 for the sun.

·                     Use the welding curtains

2- Safety glasses must be worn in the shop at all times!

3- When operating any piece of machinery—

·         No loose fitting clothing, jewelry, or hair; tie it back or remove it.

·         Only one person is allowed to operate any one machine at a time.

·         Keep your hands well clear of cutting blades.

·         Clamp the work-piece when cutting or drilling it.

·         Never leave a machine that is running unattended.

·         Consult the teacher before cutting metal different than hot or cold-rolled steel.

4- Cutting Fluid.

We use a water-based cutting fluid which can cause itching if it comes in contact with your skin, so wash it off ASAP if it does come in contact with your skin; in addition, wipe it off of your work-piece with paper towel.

5- The bench drill press.

                Use cutting fluid when drilling into metal.

                Correctly adjust the drill speed (consult teacher before using).

                Correctly adjust the feed speed (consult teacher before using).

6- The hand grinder.

                Never grind toward another person or a flammable object.

7- The bench grinder.

                Keep your hands well clear of grinding wheels.

                Use vise-grips to hold objects that are smaller than 4".

                Never grind an object unless the table is 1/16” away from the grindstone.

8- The manual and hydraulic metal shear and iron worker.

                Clamp the work-piece to be cut.

                Do not exceed the cutting capacity of the machines.

9- The cold cut saw.

Always clamp the metal tightly.

Never cut a piece of round hollow tubing on an angle other than 90 degrees without instructor permission.

Make sure the cutting fluid is flowing properly onto the saw-blade and work-piece.

                Cut on high speed only unless advised otherwise by the instructor.

10- No sandals or shorts in the shop area.
