Nordson EFD Product Safety Statement (continued)
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components.
Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage.
Halogenated hydrocarbon solvents contain one or more of the following elements.
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check the Safety Data Sheet (SDS) or contact your material supplier for more information. If you must use
halogenated hydrocarbon solvents, contact your EFD representative for compatible EFD components.
High Pressure Fluids
High pressure uids, unless they are safely contained, are extremely hazardous. Always release uid pressure before
adjusting or servicing high pressure equipment. A jet of high pressure uid can cut like a knife and cause serious
bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning.
Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury:
• Go to an emergency room immediately.
• Tell the doctor that you suspect an injection injury.
• Show the doctor the following note.
• Tell the doctor what kind of material you were dispensing.
WARNING
Medical Alert — Airless Spray Wounds: Note to Physician
Injection in the skin is a serious traumatic injury. It is important to treat the injury surgically as soon as possible. Do
not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the
bloodstream.
Qualified Personnel
Equipment owners are responsible for making sure that EFD equipment is installed, operated, and serviced by
qualied personnel. Qualied personnel are those employees or contractors who are trained to safely perform
their assigned tasks. They are familiar with all relevant safety rules and regulations and are physically capable of
performing their assigned tasks.
