Medical Examination Frequently Asked Questions For Respirators

Conventional health and safety practice has stressed the main role of individual protective devices in supplying worker security and achieving OSHA compliance. Progressively, however, security and health specialists are engaging plant supervisors and production supervisors in discussion of a new paradigm: How breathing defense systems can actually increase worker performance, comfort and spirits, which can lead to minimized manufacturing expenses.

In particular, positive-pressure respirators (notably, supplied-air respirators with loose-fitting face pieces, hoods or helmets and powered air-purifying respirators-- see "Definitions You Need to Know") are moving well beyond the recognized compliance-driven function of securing workers' breathing and ending up being valuable work environment productivity tools.

• The decrease of relocating components reduced production costs and increased longevity.
• Research suggests that disagreement with breathing protection requirements is common and implementing new techniques is tough.
• A downside of this setup is that if a nonsymptomatic, however contagious wearer is exhaling an infection or various other microorganism, the infection or microorganism might bypass the filter, be released to the outside environment, and also potentially infect individuals in the prompt location.

This is welcome news for safety and health professionals, who require management assistance and employee acceptance to make their respiratory protection programs work. In fact, so particular is the effect that some plant supervisors and managers are leading the charge for positive-pressure systems, and their staff members aspire to attempt them and use them regularly.



In addition to securing employees from airborne pollutants, the equipment can be utilized to secure the eyes, head and face, and to defend against heat stress, when combined with a Vortex cooling system. There are likewise performance, item quality, worker comfort and morale benefits that are triggering whole markets to reassess how they carry out respirator protection programs.

" Employers are just starting to see business case for positive-pressure respirators [PPR]," according to Tom Nelson, CIH, previous business health and safety manager for DuPont and now a commercial health expert. "A properly designed respirator program and the suitable PPR system allows companies to increase paint shop efficiency, 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 beneficial, even when engineering manages avoid overexposures," said Wes Norton, CIH, CSP, who has more than 20 years of industrial experience. "When you provide workers a choice in between a half-face piece, negative-pressure respirator and a supplied-air respirator with a loose-fitting hood or helmet, they select the supplied-air system because of the convenience advantages. Once they attempt provided air, they never wish 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 most workers," Norton said. "Great, proficient painters are tough to discover and crucial to keep delighted. When they are supplied comfy breathing security, the quality of work is greater and absenteeism is reduced."


Respirator programs that utilize positive-pressure systems with loose-fitting helmets and hoods are easier to administer, according here to Jerry Guilliams, a Boeing Co. senior industrial hygienist and safety specialist. These types of respirators, he pointed out, do not require in shape testing, and users need not be clean-shaven. "Right there, you have gotten rid of two considerable aspects of worker resistance," said Guilliams, who works for Boeing's Military Aircraft and Missile Systems Group in St. Louis.
Quality Paint Job at Piper Aircraft
New Piper Aircraft Inc. manufactures single-engine airplanes for private, commercial and flight school use. At its 1,200-employee facility in Vero Beach, Fla., New Piper Airplane runs a modern paint buy 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 using full-face, negative-pressure respirators. Sadly, paint overspray and incompatibility with prescription eyeglasses were affecting employees' clear vision, which was hurting the quality of the paint job.

The solution was to change to a supplied-air respirator with a loose-fitting helmet and a peel-off face guard, which secures the main lens and can be changed when vision ends up being blocked by paint spray. The company also uses 3M's Vortex cooling system, which enables employees to regulate the temperature level of their breathing air by cooling it as much as 50 degrees-- a crucial health preventative measure and convenience advantage in hot, damp Florida.

" This is the best thing we have actually carried out in years," stated Dave Youmans, security organizer at the Piper Aircraft plant. "There is absolutely no trade-off among production, defense and convenience. We discovered a service that is easy for management, employees, and safety and health people to support. We do not have to require this problem at all since the quality problems are so essential. At Piper, the paint shop supervisor pushed for this solution, and the director of making spent for it out of his budget plan."

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