    Personal Safety (contd)� Obtain and read Material Safety Data Sheets

    (MSDS) for all materials used. Follow themanufacturer’s instructions for safe handlingand use of materials, and use recommendedpersonal protection devices.

    � Make sure the spray area is adequatelyventilated.

    � To prevent injury, be aware of less-obviousdangers in the workplace that often cannot becompletely eliminated, such as hot surfaces,sharp edges, energized electrical circuits, andmoving parts that cannot be enclosed orotherwise guarded for practical reasons.

    High-Pressure Fluids

    High-pressure fluids, unless they are safelycontained, are extremely hazardous. Alwaysrelieve fluid pressure before adjusting or servicinghigh pressure equipment. A jet of high-pressurefluid can cut like a knife and cause serious bodilyinjury, amputation, or death. Fluids penetrating theskin can also cause toxic poisoning.

    If you suffer a fluid injection injury, seek medicalcare immediately. If possible, provide a copy of theMSDS for the injected fluid to the health careprovider.

    The National Spray Equipment ManufacturersAssociation has created a wallet card that youshould carry when you are operating high-pressurespray equipment. These cards are supplied withyour equipment. The following is the text of thiscard:

    WARNING: Any injury caused by highpressure liquid can be serious. If you areinjured or even suspect an injury:

    � Go to an emergency room immediately.

    � Tell the doctor that you suspect an injectioninjury.

    � Show him this card

    � Tell him what kind of material you were spraying

    MEDICAL ALERT—AIRLESS SPRAY WOUNDS:NOTE TO PHYSICIAN

    Injection in the skin is a serious traumatic injury. Itis important to treat the injury surgically as soon aspossible. Do not delay treatment to researchtoxicity. Toxicity is a concern with some exoticcoatings injected directly into the bloodstream.

    Consultation with a plastic surgeon or areconstructive hand surgeon may be advisable.

    The seriousness of the wound depends on wherethe injury is on the body, whether the substance hitsomething on its way in and deflected causingmore damage, and many other variables includingskin microflora residing in the paint or gun whichare blasted into the wound. If the injected paintcontains acrylic latex and titanium dioxide thatdamage the tissue’s resistance to infection,bacterial growth will flourish. The treatment thatdoctors recommend for an injection injury to thehand includes immediate decompression of theclosed vascular compartments of the hand torelease the underlying tissue distended by theinjected paint, judicious wound debridement, andimmediate antibiotic treatment.

    Fire Safety To avoid a fire or explosion, follow theseinstructions.

    � Ground all conductive equipment. Use onlygrounded air and fluid hoses. Check equipmentand workpiece grounding devices regularly.Resistance to ground must not exceed onemegohm.

    � Shut down all equipment immediately if younotice static sparking or arcing. Do not restartthe equipment until the cause has beenidentified and corrected.

    � Do not smoke, weld, grind, or use open flameswhere flammable materials are being used orstored.

    � Do not heat materials to temperatures abovethose recommended by the manufacturer.Make sure heat monitoring and limiting devicesare working properly.

    � Provide adequate ventilation to preventdangerous concentrations of volatile particles orvapors. Refer to local codes or your materialMSDS for guidance.

    � Do not disconnect live electrical circuits whenworking with flammable materials. Shut offpower at a disconnect switch first to preventsparking.

    � Know where emergency stop buttons, shutoffvalves, and fire extinguishers are located. If afire starts in a spray booth, immediately shut offthe spray system and exhaust fans.

    � Shut off electrostatic power and ground thecharging system before adjusting, cleaning, orrepairing electrostatic equipment.

    � Clean, maintain, test, and repair equipmentaccording to the instructions in your equipmentdocumentation.

    � Use only replacement parts that are designedfor use with original equipment. Contact yourNordson representative for parts informationand advice.

    Halogenated Hydrocarbon SolventHazards

    Do not use halogenated hydrocarbon solvents in apressurized system that contains aluminumcomponents. Under pressure, these solvents canreact with aluminum and explode, causing injury,death, or property damage. Halogenatedhydrocarbon solvents contain one or more of thefollowing elements:

    Element Symbol Prefix

    Fluorine F “Fluoro-”

    Chlorine Cl “Chloro-”

    Bromine Br “Bromo-”

    Iodine I “Iodo-”

    Check your material MSDS or contact your materialsupplier for more information. If you must usehalogenated hydrocarbon solvents, contact yourNordson representative for information aboutcompatible Nordson components.

    Action in the Event of aMalfunction If a system or any equipment in a systemmalfunctions, shut off the system immediately andperform the following steps:

    � Disconnect and lock out system electricalpower. Close hydraulic and pneumatic shutoffvalves and relieve pressures.

    � Identify the reason for the malfunction andcorrect it before restarting the system.

    Disposal Dispose of equipment and materials used inoperation and servicing according to local codes.
