Clinical Evaluation Frequently Asked Questions For Respirators

Traditional health and safety practice has stressed the primary function of individual protective equipment in offering employee protection and accomplishing OSHA compliance. Significantly, nevertheless, security and health professionals are engaging plant managers and production managers in discussion of a new paradigm: How breathing defense systems can actually increase worker efficiency, convenience and spirits, which can lead to decreased production 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 Required to Know") are moving well beyond the established compliance-driven function of securing workers' breathing and ending up being important office productivity tools.

• This test was made to assess scientific performance, taking into account lots of obstacles of working in outpatient health care setups.
• The bistable fluid amplifier style allowed the respirator to function as both a respiratory assistor and controller.
• For the more comprehensive post, on both favorable- as well as negative-pressure gadgets, see Mechanical air flow.

This is welcome news for safety and health experts, who require management assistance and staff member acceptance to make their respiratory security programs work. In fact, so specific is the effect that some plant supervisors and managers are leading the charge for positive-pressure systems, and their employees are eager to try them and utilize them frequently.



In addition to securing workers from airborne pollutants, the devices 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 also efficiency, item quality, staff member convenience and spirits benefits that are causing entire industries to reconsider how they execute respirator defense programs.

" Companies are simply beginning to see the business case for positive-pressure respirators [PPR]," according to Tom Nelson, CIH, former corporate health and safety supervisor for DuPont and now a commercial health expert. "A properly designed respirator program and the appropriate PPR system enables companies to increase paint shop efficiency, be more effective in repair and maintenance operations, or do more grinding, cutting and welding."

" There are a great deal of operations where positive-pressure respirators are helpful, even when engineering manages prevent overexposures," said Wes Norton, CIH, CSP, who has more than 20 years of industrial experience. "When you provide workers 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 provided air, they never ever want to give it up, and they don't complain about using it."





For example, in paint shops, Norton has seen worker turnover and absenteeism considerably minimized due to a well-implemented, supplied-air respirator program. "Conditions in paint cubicles are not the first choice of a lot of staff members," Norton stated. "Excellent, knowledgeable painters are tough to discover and important to keep happy. When they are provided comfortable respiratory protection, the quality of work is higher and absenteeism is reduced."


Respirator programs that use positive-pressure systems with loose-fitting helmets and hoods are easier to administer, according to Jerry Guilliams, a Boeing Co. senior industrial hygienist and safety specialist. These types of respirators, he pointed out, do not require fit testing, and users need not be clean-shaven. "Right there, you have eliminated two significant aspects of worker resistance," said Guilliams, who works for Boeing's Military Aircraft and Missile Systems Group in St. Louis.
Quality Paint Task at Piper Airplane
New Piper Airplane Inc. makes single-engine aircrafts for personal, business and flight school usage. At its 1,200-employee center in Vero Beach, Fla., New Piper Airplane runs an advanced paint purchase using several coats of paint on the airplanes. It is a demanding, high-precision job. To protect workers from paint overspray, the company had been using full-face, negative-pressure respirators. Unfortunately, paint overspray and incompatibility with prescription eyewear were impacting staff members' clear vision, which was injuring the quality of the paint task.

The option was to change to a supplied-air respirator with a loose-fitting helmet and a peel-off face guard, which safeguards the primary lens and can be replaced when vision becomes obstructed by paint spray. The company also utilizes 3M's Vortex cooling click here system, which makes it possible for staff members to manage the temperature level of their breathing air by cooling it as much as 50 degrees-- an essential health safety measure and comfort benefit in hot, humid Florida.

" This is the very best thing we have actually performed in years," said Dave Youmans, safety coordinator at the Piper Aircraft plant. "There is absolutely no compromise amongst production, security and convenience. We found a solution that is easy for management, employees, and security and health individuals to support. We do not need to force this issue at all because the quality issues are so crucial. At Piper, the paint store manager promoted this service, and the director of manufacturing paid for it out of his spending plan."

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.
