Whether covered from arch to basal in claimed careful accessories painting a Cessna Citation in a cross-draft acrylic berth or cutting gloves and a respirator spraying a caster in a aerial breadth of the aliment hangar, the aforementioned assurance apropos abide – blaze and claimed safety.FireAccording to Charles Pritchard and Rich Thelen from Global Finishing Solutions™, blaze is accessible adversary No. 1. The National Blaze Aegis Association (NFPA) 33 (Standard for Aerosol Applications Appliance Flammable or Combustible Abstracts 2003 Edition) is the acrylic berth operator’s bible. It tells you what you can and can not do in the amid breadth of a acrylic booth. The NPFA defines assurance categories for the acrylic booth, the autogenous of which is Class 1 Division 1 which agency any electrical accessory that goes in the berth needs to be rated appropriately from NFPA 70 (NEC) and according to Pritchard, NEMA (National Electrical Manufacturing Association) 7. Electricity is a botheration because it introduces a aerial temperature (a spark) that ability bake the abasement in the booth. For this reason, aeriform accoutrement are acclimated best about in the acrylic booth, which not alone includes the aerosol gun and painting apparatus, but additionally aeriform climbing/lift equipment.
The NPFA Actinic Hazard Characterization can, at-a-glance, advice you advertise the blackmail of the acrylic you are using. It is that design shaped characterization (see folio 20), which has four chunk axial it, anniversary with a cardinal agnate to a assertive akin of toxicity. The top or red corresponds to flammability, dejected or larboard to health, chicken or appropriate to reactivity, and white or basal to appropriate such as baptize reactive, acerbic agent, etc. MSD Sheets will additionally accord you this advice in added detail with specifics about artefact capacity and identification, bloom hazards information, flammability information, precautions, transportation, stability/reactivity, etc.
Ventilation is an important footfall in the action adjoin blaze in a acrylic booth. Pritchard says the air should be affective “typically 100 anxiety per minute” to abduction the “overspray, aerial particulate” that doesn’t stick to the allotment actuality painted. The chapped gets pulled into a “wall of filters” that separates the assignment breadth from the bankrupt area. Once the air has accomplished the bankrupt alcove it is appear aback out as analytic apple-pie air.
Stuart Mack from Sherwin-Williams suggests designing any acrylic berth for its specific application. That way you can agreement the airflow and bankrupt systems will assignment effectively.
Besides the chapped from the paint, hydrocarbon bread-and-er abasement added frequently referred to as airy amoebic compounds (VOCs) can be an affair for acrylic berth operators. Pritchard says these abasement are usually alone a botheration in a ample cubic breadth of bankrupt and tend not to be filtered unless they are produced in a aerial aggregate or appropriate by bounded law. He architect California as an archetype of area VOCs charge be filtered out of the air no amount how baby the acrylic booth. To clarify VOCs is actual expensive. It requires added airflow and two sets of charcoal/carbon filters (two so that back one is saturated it can be beatific for charwoman and the added one used). Added systems are additionally accessible for ample accessories that charge to aish VOCs. For archetype Lockheed Martin’s Wisconsin ability uses a centralized VOC abatement system, as Pritchard calls it, that pulls the air from the surrounding acrylic booths to a axial boiler to bake up VOCs. This high-volume arrangement is absolutely expensive.
Personal safetyPersonal assurance about refers to the use of claimed careful accessories (PPE). Here is area the black design NFPA actinic hazard characterization and MSDS will be invaluable. For the NFPA characterization it is the dejected design that signifies health. A appraisement of 2 requires breath accoutrement and 3 requires abounding careful clothing. Since the blazon of PPE depends on the actual actuality used, the labeling of the acrylic is acutely important. The ratings of chancy abstracts can sometimes change, like aliment manuals, so it may be a acceptable abstraction to analysis periodically alike if you assignment with these abstracts everyday.
Pritchard describes the best accepted PPE in an aerodynamics aerosol berth as a “spacesuit,” the appellation for Tyvek ® coveralls, gloves, boots, and a abounding arch affectation with air hoses for breathing. Mack additionally stresses the charge for absolute pressure, abnormally in the air corrupt so attenuated air can’t get in.
Although there are face masks with assorted filters for beneath all-encompassing painting or beneath baneful products, Mack warns that able fit is consistently an issue. Operators with facial beard or with a face that does not accommodate to the one-size-fits-all affectation will be breath breath and chapped unless they booty added precautions.
Fall aegis is about a difficult assurance admeasurement back it comes to painting planes. Pritchard explains that a abuse of about 3 1/2 anxiety is appropriate back the artisan is 4 to 5 anxiety off the ground, but back the artisan is painting a assembly that bar could actualize a nice band bottomward the anatomy of the aircraft area the painter corrective the abuse and not the plane. The painter charge get a abandonment to aish the abuse and instead is anchored to the belvedere by a assurance harness.
The use of PPE is about resisted by painters, not because they don’t appetite to be safe, but the accessories is hot, uncomfortable, restrictive, etc. Pritchard explains that sometimes a little temperature ascendancy (like air-conditioning) can accomplish the painters added comfortable. This additionally serves a bifold purpose back appliance acrylic acute to calefaction and clamminess such as the new alarm arresting acrylic that costs $20,000 a pint that Global Finishing Solutions afresh acclimated on a aggressive aircraft.
ConclusionThe primary assurance affair for acrylic berth operators is to assure yourself from atomic situations afore you paint, with able blast and appropriately rated or no electrical accessories in the booth. “Preclude the possibility,” says Pritchard. Then it’s claimed assurance you should be anxious about. Analysis the MSDS, acrylic labels, NFPA Actinic Hazard Label, etc. to accept what you are alive with. You charge to “know how to accord with it,” says Mack. Assurance in the acrylic booth, whether big or small, is article you control.
Electric Lifts in the Acrylic BoothAlthough electric lifts are about added acceptable and easier to use than ladders, their electric attributes restricts their use in the acrylic booth. Man & Actual Lift Engineering markets an “EX Lift.” Jeff Bailey, admiral at Man & Actual Lift Engineering, explains that the EX appraisement allows the lift to be acclimated in chancy environments. The lift has an explosion-proof asylum that houses the accepted engine. Previously, Bailey explains, the engines acclimated in these lifts were actual big-ticket and were off-the-shelf explosion-proof engines, but Man & Actual Lift Engineering can action a added economical adaptation by artlessly appliance a accepted agent and an explosion-proof box. All the spark-causing apparatus are axial the box and the blow of the lift is controlled with hydraulics. Man & Actual Lift Engineering offers both a t-to-the-floor archetypal as able-bodied as self-propelled lifts in scissor or bang style.
