Work area Safety

1.

Keep your work area clean and well lit.

Cluttered benches and dark areas invite accidents.

2.

Keep bystanders, children, and visitors away while operating.

Distractions can cause you to lose control. Protect others in the work area from intense heat. Do not allow others close enough to look at the flame as eye damage is a real possibility.

Provide barriers or shields as needed.

3.

When possible, move the work to a location well away from combustible materials.

If relocation is NOT possible, protect the combustibles with a cover made of fire resistant material. Remove or make safe all combustible materials for a radius of 35 feet (10 meters) around the work area.

4.

Enclose the work area with portable fire resistant screens.

Use a fire resistant material to block all openings and protect combustible walls, ceilings, floors, etc.

5.

if working near/on a metal wall, ceiling, floor, etc., prevent ignition of combustibles on the other side by moving the combustibles to a safe location.

If relocation of combustibles is NOT possible, designate someone to act as a fire watch equipped with a fire extinguisher during the cutting process and for at least one half hour after the cutting project is completed.

6.

Do not place the torch on any material other than bare concrete until it has cooled completely.

7.

Do not cut any material that has a combustible coating or a combustible internal structure, such as drums or tanks, without an approved method for eliminating the hazard.

8.

Do not dispose of hot slag in containers holding combustible materials.

9.

Keep a fully charged fire extinguisher close by and know the proper way to use it.

10.

after cutting make a thorough check for evidence of fire and be aware the easily visible flame or smoke may not be present for some time after a fire has started.

11.

Do not cut in atmospheres containing dangerously reactive or flammable gases, vapors, liquids, or dust.

12.

clean and purge containers before applying heat.

Do not apply heat to a container that has held an unknown substance or a combustible material whose contents, when heated, can produce flammable or explosive vapors. Vent closed containers, including castings, before preheating or cutting.

personal Safety

1.

Wearing and using personal safety clothing and safety devices reduce the risk of injury.

Wear the following:

a.

Fire-resistant clothing

(Do not wear pants with cuffs, shirts with open pockets, or any clothing that can catch and hold molten metal or sparks.) b.

Fire-resistant leather leggings and work boots

c.

Keep clothing and safety equipment free of grease, oil, solvents and any other flammable substances.

2.

Stay alert. Watch what you are doing, and use common sense when operating this torch.

Do not use while tired or under the influence of drugs, alcohol, or medication.

A moment of inattention while operating may result in serious personal injury.

3.

Do not overreach. Keep proper footing and balance at all times.

Proper footing and balance enables better control in unexpected situations.

4.

inHaLatiOn HaZarD:

Welding and cutting produce tOXic FuMES.

Exposure to cutting exhaust fumes can increase the risk of developing certain cancers, such as cancer of the larynx and lung cancer. Also, some diseases that may be linked to exposure to cutting exhaust fumes are:

• Early onset of Parkinson’s Disease

• Heart disease • Ulcers

• Damage to the reproductive organs

• Inflammation of the small intestine or stomach

• Kidney damage

• Respiratory diseases such as emphysema, bronchitis, or pneumonia

Use natural or forced air ventilation and wear a respirator approved by

NIOSH to protect against the fumes produced to reduce the risk of developing the above illnesses.

Item 96290

For technical questions, please call 1-888-866-5797.

5.

avoid overexposure to fumes and gases.

Keep your head out of the fumes. Do not breathe fumes. Use enough ventilation or exhaust, or both to keep fumes and gases away from your breathing area. Where ventilation is questionable, have a qualified technician take an air sampling to determine the need for corrective measures.

If necessary, use mechanical ventilation to improve air quality. If this is not possible, use an approved respirator. Do not work in confined areas unless they are well-ventilated or you are

Equipment Setup Safety

wearing an air supplied ventilator. Always follow

OSHA guidelines for Permissible Exposure Limits

(PEL’s) for various fumes and gases.

Follow the American Conference of Governmental

Industrial Hygienists recommendations for the Threshold Limit Values (TLV’s) for fumes and gases. Have a recognized specialist in

Industrial Hygiene or Environmental Services check the operation and air quality and make recommendations for the specific cutting situation.

1.

Make sure you are prepared to begin work before opening gas supply.

2.

to prevent explosion, use reverse-flow check valves and flashback arrestors

(sold separately) on the base of the torch.

3.

use with oxygen and acetylene only.

Do not modify this torch or use it for a purpose for which it is not intended.

4.

Set acetylene regulator no greater than 15 pSi.

Acetylene is unstable and can explode if over-pressurized.

5.

Do not use oil, grease or thread seal tape on any connector.

6.

use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform.

Holding the work by hand or against your body is unstable and may lead to loss of control, fire and/or personal injury.

7.

use only accessories that are recommended by the manufacturer for your model torch.

Accessories that may be suitable for one Torch may become hazardous when used on another Torch.

Only use proper gas hoses.

cylinder Safety

1.

Do not use dented or damaged cylinders.

2.

Secure cylinders to a cart, wall, or post to prevent them from falling.

Use and store cylinders in an upright position only.

3.

use cylinder caps when moving or storing cylinders.

4.

Do not store cylinders in temperatures 120° F or higher.

2.

inSpEct BEFOrE EVEry uSE.

Look for the following, and do not use kit if any damage is noted:

a.

inspect the tapered seating surfaces on the nozzles and the tip nut.

Have a qualified technician resurface the seat area if it has dents, burrs, or is burned. A poor seating surface may result in backfire or flashback.

b.

Examine all hoses for cuts, cracks, burns, worn areas, or other damage.

Do not use if damaged.

c.

check for loose connections using soapy water solution.

Tighten or repair any leaks found.

d.

Do not use the torch Kit if either gas does not turn off completely when the Oxygen torch Valve and acetylene torch Valve are closed.

Leakage of gas from the tip is a substantial safety risk.

If gas cannot be turned off at the Torch Handle, it is dangerous and must be replaced.

e.

inspect for any other defects or damage.

Do not use any damaged parts.

Tag damaged parts “Do not use” until repaired.

Item 96290

Operation Safety

1.

inspect before every use; see previous warning section.

2.

use only with proper ventilation.

3.

Do not touch workpiece or tip until cool.

4.

Keep hoses away from hot parts, from cut area, and from flame.

5.

never leave the torch unattended when it is attached to a gas supply.

6.

allow sufficient time for the torch to completely cool before storing.

7.

any material discharged from the work area during use will be extremely hot.

Use care to not get burned by slag or other waste products.

8.

BacKFirE:

When the flame goes out with a loud “pop,” it is called a

backfire.

Backfire can be caused by: a. Operating the Torch at lower pressures than required for the Tip used.

b. Touching the Tip against the workpiece.

c. Overheating the Tip.

d. An obstruction in the Tip.

If backfire occurs, close the Torch Handle Valves

(oxygen first, then acetylene) and after remedying the cause, relight the torch.

9.

FLaSHBacK:

Flashback

is a condition that results when the flame flashes back into the Torch and burns inside with a shrill hissing or squealing noise.

if flashback occurs, close the torch Handle Valves

(oxygen first, then acetylene) iMMEDiatELy!

Flashback generally indicates a problem that should be repaired before proceeding with the job at hand.

A clogged Tip, improper functioning of the Valves, or incorrect acetylene/oxygen pressure could lead to flashback. Find and correct the cause before relighting the Torch.

If the cause is not found, have the kit serviced by a qualified technician before returning to your project.

10.

Beware of leaking gas. if you notice the odor of acetylene during use, close the torch Handle Valves

(oxygen first, then acetylene) iMMEDiatELy!

Extinguish all open flames and carefully check all hoses and connections for leaks using soapy water.

nEVEr check for leaks using a flame.

If the odor continues do not use the Torch.

Call acetylene supplier for assistance.

11.

read and understand all instructions and safety precautions as outlined in the manufacturer’s manual for the material you will cut.

12.

after use, bleed lines and store all components out of reach of children and other untrained persons.

Torches are dangerous in the hands of untrained users.
