I-Rod load values (when using I-Rod as a beam dressing )
Piping engineers: Use the following maximum loading for each I-Rod. Up to three rods can be used to achieve desired weight loading:
1 in I-Rod 8,000 lb (3636 Kg) 1 ½ in I-Rod 10,000 lb (4545 Kg)
The table below conservatively estimates total weight/foot of pipe filled with water. Multiply this number by support spacing to get total weight loading, then select number of 1 in. I-Rods if pipe is less than 12 in. 1 ½ in. I-Rods are generally recommended for piping over 12 in. Do not mix rod sizes.

I-Rod material health-hazard data (standard I-Rod material only)
ACUTE OR IMMEDIATE EFFECTS: Routes of entry and systems
INGESTION: Not a probable route of exposure
SKIN: Molten I-Rod® causes thermal burns
EYE: Mechanical irritation only
INHALATION: Shapes not respirable
Emergency first aid
• If exposed to fumes from overheating, move to fresh air. Consult a physician if symptoms persist
• Wash skin with soap and plenty of water
• Flush eyes with water. Consult a physician if symptoms persist. • If molten I-Rod contacts skin, cool rapidly with cold water. Do not attempt to peel I-Rod from skin. Obtain medical attention to thermal burn.
Chronic effects: Chronic inhalation studies in animals have shown that formaldehyde causes cancer in rats. The international agency for research on cancer has classified formaldehyde as a carcinogen in group 2A, and the national toxicology program includes formaldehyde in its annual report on carcinogens. The OSHA TWA for formaldehyde is 0.75 ppm. The ACGIH TLV is 1 ppm. The OSHA and ACGIH STEL is 2 ppm.
Medical conditions generally aggravated by this material: No data are available which addresses medical conditions that are generally recognized as being aggravated by exposure to this product.
Fire and explosion hazard data
Flash ignition temperature: 608° F. / 320° C. Method: ASTM D-1929
Unusual fire, explosion hazards: None known
Hazardous combustion products: Formaldehyde may be released if product is exposed to excessive heat or fire.
Special fire-fighting instructions: Fire fighters and others exposed to products of combustion should wear full protective clothing including a self-contained breathing apparatus. Fire-fighting equipment should be thoroughly decontaminated after use.
Extinguishing media: Water spray or any class A extinguishing agent.
Uses
I-Rod is to be used in outdoor environments to eliminate crevice corrosion at the pipe and the pipe support interface where water can accumulate. There is not any reason to use this product in an indoor environment. The quantity of I-Rod is very small, thus the amount of combustion products will be minimal. I-Rod® has been used in thousands of applications in the oil and gas industry without any reports of combustion gases being released from this product.
