Medical Evaluation Frequently Asked Questions For Respirators

Standard health and safety practice has actually emphasized the primary role of individual protective equipment in supplying worker security and attaining OSHA compliance. Increasingly, however, safety and health experts are engaging plant supervisors and production managers in discussion of a brand-new paradigm: How respiratory protection systems can really increase employee performance, comfort and morale, which can result in lowered production costs.

In particular, positive-pressure respirators (significantly, supplied-air respirators with loose-fitting face pieces, hoods or helmets and powered air-purifying respirators-- see "Meanings You Required to Know") are moving well beyond the established compliance-driven role of safeguarding employees' breathing and becoming important workplace efficiency tools.

• Modern ventilators are online controlled by a little ingrained system to enable specific adaptation of stress and also flow attributes to an individual client's demands.
• For filtration as well as capturing of aqueous bits, polypropylene fiber surface areas require adjustment to provide them more hydrophilic since polypropylene is naturally hydrophobic.
• Meanwhile, Allegheny Health and wellness has actually switched its entire personnel to MSA's elastomeric half-mask respirators.

This is welcome news for security and health specialists, who need management support and worker approval to make their breathing defense programs work. In fact, so certain is the impact that some plant managers and managers are leading the charge for positive-pressure systems, and their staff members aspire to try them and use them routinely.



In addition to safeguarding employees from air-borne contaminants, the equipment can be used to safeguard the eyes, head and face, and to defend against heat tension, when integrated with a Vortex cooling system. There are also productivity, product quality, worker convenience and spirits advantages that are triggering entire industries to rethink how they implement respirator security programs.

" Employers are simply starting to see business case for positive-pressure respirators [PPR]," according to Tom Nelson, CIH, previous corporate health and safety manager for DuPont and now an industrial hygiene specialist. "A properly designed respirator program and the proper PPR system makes it possible for companies to increase paint shop productivity, be more efficient in maintenance and repair operations, or do more grinding, cutting and welding."

" There are a great deal of operations where positive-pressure respirators are useful, even when engineering manages prevent overexposures," said Wes Norton, CIH, CSP, who has more than 20 years of industrial experience. "When you provide employees an option in between a half-face piece, negative-pressure respirator and a supplied-air respirator with a loose-fitting hood or helmet, they pick the supplied-air system because of the convenience advantages. Once they attempt supplied air, they never want to give it up, and they don't complain about using it."





For example, in paint shops, Norton has actually seen worker turnover and absence substantially lowered due to a well-implemented, supplied-air respirator program. "Conditions in paint cubicles are not the first choice of the majority of staff members," Norton stated. "Good, skilled painters are hard to find and important to keep happy. When they are offered comfortable respiratory security, the quality of work is higher and absenteeism is decreased."


Respirator programs that utilize positive-pressure systems with loose-fitting helmets and hoods are simpler to administer, according to Jerry Guilliams, a Boeing Co. more info senior commercial hygienist and security expert. These kinds of respirators, he explained, do not need healthy screening, and users require not be clean-shaven. "Right there, you have actually removed 2 substantial elements of worker resistance," said Guilliams, who works for Boeing's Armed force Aircraft and Rocket Systems Group in St. Louis.
Quality Paint Task at Piper Aircraft
New Piper Aircraft Inc. manufactures single-engine planes for private, commercial and flight school use. At its 1,200-employee facility in Vero Beach, Fla., New Piper Aircraft runs a state-of-the-art paint shop for using numerous coats of paint on the aircrafts. It is a requiring, high-precision task. To secure employees from paint overspray, the business had actually been utilizing full-face, negative-pressure respirators. Sadly, paint overspray and incompatibility with prescription eyeglasses were affecting workers' clear vision, which was hurting the quality of the paint job.

The solution was to switch to a supplied-air respirator with a loose-fitting helmet and a peel-off face shield, which secures the main lens and can be changed when vision ends up being blocked by paint spray. The business likewise uses 3M's Vortex cooling system, which allows employees to regulate the temperature of their breathing air by cooling it as much as 50 degrees-- an important health precaution and convenience advantage in hot, damp Florida.

" This is the best thing we've done in years," stated Dave Youmans, security planner at the Piper Airplane plant. "There is definitely no trade-off among production, defense and comfort. We found a service that is easy for management, employees, and safety and health individuals to support. We do not need to force this problem at all because the quality issues are so important. At Piper, the paint store manager promoted this service, and the director of producing paid for it out of his budget."

The success in the paint store has actually resulted in the maintenance department's interest in supplied-air respirators. Despite the short-term, scattered nature of maintenance work, Youmans stated, a supplied-air program can be made practical for upkeep workers by stationing high-pressure, supplied-air sources throughout the plant.
