Material and Solvent Precautions

Heated Materials
Heated materials may cause severe burns on contact. Remember that some materials, even solid materials, may retain heat for some time. If you are burned by a heated material, immediately cool the affected skin with lots of cool, clean water. Do not try to remove hot, melted material from the skin. Seek immediate medical attention.

Injection Hazard
High-pressure fluids, unless they are safely contained are extremely hazardous. A jet of high-pressure fluid can act like a knife or needle, penetrate skin and muscle, and inject itself into your body. Injection fluids can cause toxic poisoning. Do not treat an injection injury as minor. Seek medical care immediately. Inform the medical staff at the hospital that you have an injection injury and identify the fluid that was injected. If possible, give the doctor copies of the MSDS for the injected fluid and for any additives, such as solvents that are in the injected fluid. Nordson recommends that you carry a National Safety Equipment Manufacturers Association (NSEMA) wallet card to give to emergency medical staff in the event of an injection injury. These cards are supplied with the equipment. Additional cards are available free from Nordson Corporation.

  • Always handle fluid dispensing devices carefully. Do not point the nozzle of a pressurized device at yourself or other personnel.

  • Never place hands, fingers or other parts of your body directly over a nozzle or near a leak in a high-pressure system.

  • Never "back-flush" the nozzles. Blocking a nozzle causes the high-pressure fluid to change direction. An injection injury may result.

  • Always relieve system pressure before servicing equipment. Trigger all dispensing devices and bleed off system pressure.

Halogenated Hydrocarbon Solvents
Halogenated hydrocarbon solvents can cause an explosion when used with aluminum components in a pressurized fluid pumping system (pumps, heaters, filters, valves, spray guns and tanks). The explosion could cause serious bodily injury, death or substantial property damage. No available stabilizers will prevent this violent reaction from happening.

  • Use nonhalogenated solvents.

  • Contact your solvent supplier to determine whether your existing materials and solvents contain
    halogenated hydrocarbons or to obtain a suitable, nonhalogenated hydrocarbon solvent for cleaning and flushing out your system.

  • Check the labels on your solvent containers. Halogenated hydrocarbon solvents can be recognized if any of the following elements are listed in the name of the product or as an ingredient:

  • Pump the system empty, shut-off the pumps, and relieve the system pressure.

     Element Symbol Prefix
    Flourine F "Flouro-" 
    Chlorine Cl "Chloro-"
    Bromine Br "Bromo-"
    Iodine I "Iodo-"

  • Disassemble and inspect the system components. Replace any damaged or corroded parts.

  • Thoroughly clean all noncorroded parts with nonhalogenated hydrocarbon solvents before reassembling the system.

  • Contact your coatings, solvent or adhesive supplier for a nonhalogenated solvent to thoroughly flush the entire system before operating it.

  • If you must use halogenated hydrocarbon solvents, consult your Nordson representative about compatible Nordson components.
