Item 57574 
        

11. 

Do not weld or 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, cutting, or welding.

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. 

Dry, insulating leather welding gloves

d. 

NIOSH-approved respirator

e. 

Shade 5 or higher welding goggles

f. 

Appropriate head covering to 
protect head and neck

g. 

Fire-resistant ear plugs or ear muffs (if welding 
or cutting overhead or in confined spaces)

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 
Regulator.   
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 welding or 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 welding or 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.

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 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 welding or cutting situation.
