1.0 Safety Precautions 1.1 Safety - English

WARNING: These Safety Precautions are

for your protection. They summarize pre-

cautionaryinformationfromthereferences

listed in Additional Safety Information sec-

tion. Before performing any installation or operating

procedures, be sure to read and follow the safety

precautions listed below as well as all other manuals,

materialsafetydatasheets,labels,etc.Failuretoobserve

Safety Precautions can result in injury or death.

PROTECT YOURSELF AND OTHERS --

Some welding, cutting, and gouging

processes are noisy and require ear

protection.Thearc,likethesun,emits

ultraviolet (UV) and other radiation

and can injure skin and eyes. Hot metal can cause

burns. Training in the proper use of the processes

and equipment is essential to prevent accidents.

Therefore:

1. Always wear safety glasses with side shields in any

workarea,evenifweldinghelmets,faceshields,and

goggles are also required.

2. Use a face shield ﬁtted with the correct ﬁlter and

cover plates to protect your eyes, face, neck, and

ears from sparks and rays of the arc when operat-

ing or observing operations. Warn bystanders not

to watch the arc and not to expose themselves to

the rays of the electric-arc or hot metal.

3. Wear ﬂameproof gauntlet type gloves, heavy long-

sleeve shirt, cuﬄess trousers, high-topped shoes,

and a welding helmet or cap for hair protection, to

protect against arc rays and hot sparks or hot metal.

Aﬂameproofapronmayalsobe desirableas protec-

tion against radiated heat and sparks.

4. Hot sparks or metal can lodge in rolled up sleeves,

trouser cuﬀs, or pockets. Sleeves and collars should

bekeptbuttoned,andopenpocketseliminatedfrom

the front of clothing.

5. Protect other personnel from arc rays and hot

sparks with a suitable non-ﬂammable partition or

curtains.

6. Usegogglesoversafety glasseswhen chippingslag

orgrinding.Chipped slagmaybehot andcan ﬂy far.

Bystanders should also wear goggles over safety

glasses.

FIRES AND EXPLOSIONS -- Heat from

ﬂames and arcs can start ﬁres. Hot

slag or sparks can also cause ﬁres and

explosions. Therefore:

1. Remove all combustible materials well away from

the work area or cover the materials with a protec-

tivenon-ﬂammablecovering.Combustiblematerials

include wood, cloth, sawdust, liquid and gas fuels,

solvents, paints and coatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks or

crevices in ﬂoors or wall openings and cause a hid-

densmolderingﬁreorﬁresontheﬂoorbelow.Make

certain that such openings are protected from hot

sparks and metal.“

3. Donotweld,cutorperformother hotworkuntilthe

workpiecehasbeencompletelycleanedsothatthere

are no substances on the workpiece which might

produce ﬂammable or toxic vapors. Do not do hot

work on closed containers. They may explode.

4. Haveﬁreextinguishingequipmenthandyforinstant

use, such as a garden hose, water pail, sand bucket,

orportableﬁreextinguisher.Be sureyouaretrained

daño, particularmente en espacios

sin ventilación. No inhale el humo

o gases. El gas de protección puede

causar falta de oxígeno.

Por lo tanto:

1. Siempre provea ventilación adecuada en el área

de trabajo pormedionaturalomecánico.Nosolde,

corte, o ranure materiales con hierro galvanizado,

acero inoxidable, cobre, zinc, plomo, berílio, o cad-

mio a menos que provea ventilación mecánica

positiva . No respire los gases producidos por

estos materiales.

2. No opere cerca de lugares donde se aplique sub-

stancias químicas en aerosol. El calor de los rayos

del arco pueden reaccionar con los vapores de

hidrocarburo clorinado paraformarun fosfógeno,

o gas tóxico, y otros irritant es.

3. Si momentáneamente desarrolla inrritación de

ojos, nariz o garganta mientras est á operando, es

indicación de que la ventilación no es apropiada.

Pare de trabajar y tome las medidas necesarias

para mejorar la ventilación en el área de trabajo.

No continúe operando si el malestar físico per-

siste.
