Additional Information:

What independent tests have been performed on the iEvac®?

Certification
The iEvac® Smoke/Fire Hood is certified by the Safety Equipment Institute (SEI) as being in complete conformance with ANSI/ISEA 110-2009, American National Standard for Air-Purifying Respiratory Protective Smoke Escape Devices. This certification is earned after extensive independent testing to prove compliance with every requirement in the Standard. This testing was performed by Intertek and Assay Technology.

Total Performance
The iEvac® Smoke/Fire Hood has a recorded protection factor greater than 90,000. iEvac® is a smoke escape hood, an air purifying respiratory device for evacuation in case of an emergency. Its overall effectiveness depends on the filters, the nose cup and the neck dam. Each of these three integrated elements must play a part in order for the entire hood to be protective. The overall effectiveness is determined by a Fit Test, and is measured by checking the performance during a series of standardized exercises. The Fit Test result is expressed as the protection factor of the iEvac®. For reference, OSHA has assigned a protection factor of 10 for N95 masks and 50 for rubberized full face masks. Another benchmark is the NIOSH test requirement for CBRN APER masks (respirators for escape from toxic and dangerous atmospheres containing chemical, biological, radiological and nuclear hazards). NIOSH requires a protection factor of 2,000 for these masks. The U.S. Army Research, Development and Engineering Command - Edgewood Chemical Biological Center in Aberdeen, Maryland conducted tests of the iEvac® using the NIOSH methods and procedures. Under these rigorous protocols, they measured the fit test protection factor for the iEvac® as being greater than 90,000.

ANSI 110 Total Performance Requirements
The total performance of a respirator may be determined by calculating its total inward leakage. This is determined by measuring the concentration of a challenge substance outside of the respirator, the concentration within the breathing zone and comparing the two results. Clearly, the best respirators are those with a very low Total Inward Leakage.

The iEvac® Smoke/Fire Hood has a recorded Total Inward Leakage measured inside the nose cup of less than 0.01%. This characteristic was measured by the U.S. Army Research, Development and Engineering Command - Edgewood Chemical Biological Center in Aberdeen, Maryland. For reference, the requirement for certification to the ANSI 110 standard is that the Total Inward Leakage inside the nose cup shall not exceed 2%.

It is also important to consider the possibility of leakage through the neck seal into the hood. If this were to happen, the wearer’s eyes could be affected and vision obscured by smoke. This characteristic is different from the Total Inward Leakage which is measured inside the nose cup. This measurement taken within the hood but outside the nose cup is known as the ocular leakage. The U.S. Army Research, Development and Engineering Command - Edgewood Chemical Biological Center in Aberdeen, Maryland measured and recorded the ocular leakage of the iEvac® Smoke/Fire Hood as less than 0.1%. For reference, the requirement for certification to the ANSI 110 standard is that the ocular leakage shall not exceed 20%.

Gases
The iEvac® filters are a proprietary blend of materials specifically formulated to be effective against a wide range of gases and particulates. (Tests against particulates are described below.) Probably the two most dangerous gases encountered during an emergency escape from a fire are carbon monoxide and hydrogen cyanide. These special filters will provide protection against both these gases. They are designed to provide protection against these life-threatening products of combustion and also against other toxic industrial gases and terrorist gases.

iEvac® filters have been independently tested against gases.
Among the tests are the following:

Particles
The iEvac® filters are a proprietary blend of materials specifically formulated to be effective against a wide range of particulates and gases. (Tests against gases are described above.) In keeping with its design excellence, the iEvac® filters contain the best possible particle filter, a high efficiency particulate air HEPA filter. This is the same material used in military gas masks to provide protection against biohazards. The HEPA filter will remove 99.996% of particles that are 0.2 microns in size. It is this ability of the filters to remove sub-micron particulates that keeps out the small particles that may be present in smoke. Also, the filters will remove very heavy particles such as soot. During this test, the filters must remove the soot from the air and still not clog the filters so that it is too difficult to breathe.

Breathing Resistance
The iEvac® filters are very protective and also designed for easy breathing. This is important in all applications but is particularly necessary in emergency situations when the wearer may be inclined to panic. The iEvac® is tested for both inhalation and exhalation resistance.

Physical Hazards
Many physical hazards may be encountered when escaping from a fire. There will be flames, heat, hot material dripping, and other hazards. Vision will be very important, as will the need for the packaging to stand up to vibration and puncture threats from sharp objects.

Inhalation Temperature
It is important to establish that the air that comes through the filters does not become overheated by the filtration process. This is established by passing 5000 ppm carbon monoxide at a temperature of 77°F (25°C) and checking for an increase in air temperature.

Flammability
Tests for heat and flame resistance. During theses tests components will not have an afterflame longer than 5 seconds. No component will drip, melt or develop a visible hole or be damaged so that eyes or lungs are exposed to smoke. These tests involve a temperature of 1475°F (800°).

Molten drip
In this test, a flaming drip from an ignited polypropylene rod is allowed to drop onto the hood. No after flame lasts longer than 5 seconds.

Radiant heat
The hood is exposed to a radiant heat panel comprising two quartz lamps with a surface temperature between 980°F (527°C) and 1700°F (927°C) determined from a spectral emittance curve. The hood is located 9.5 inches away from the radiant heat panel and exposed for 15 seconds. The requirement is that the hood is not damaged in a way that exposes eyes or lungs to gas or smoke and that the temperature at the top of the head and inside the eyepiece shall not exceed 158°F (70°C). The hood passed.

Putting the hood on very quickly
The hood can be unpackaged and put on in less than 30 seconds

Optical properties
Light transmission, haze and field of vision are all tested to make sure that the viewing area is big enough and durable enough.

Fogging
A test is conducted to ensure that a person can clearly read a standard eye chart while wearing the hood.

Corrosion
The hood is exposed to a corrosive salt spray, and tested afterwards

Vibration
This test involves vibrating the packaging for 10,000 cycles.

Puncture and tear
The package is raked by a sharp pointed heavy striker. The packaging does not puncture, rip or tear

Operational Package Leakage
The package is immersed in water heated to a temperature of 160°F (70°C) to a depth of 24 inches (600 mm) and must not leak.

Temperature exposure
The packaged hood is exposed to a temperature of 32°F (0°C) for 24 hours then exposed to 180°F (70°C) for 24 hours. Then the hood is unpacked and tested for performance.

Pressure conditioning
The packaged hood is exposed to 100 cycles of differential pressure. Each cycle is 60 seconds at ambient, 20 seconds going from ambient to 300 mbar below, 60 seconds at 300 mbar below and 20 seconds back to ambient. Then the hood is unpacked and tested for performance.

More Test Data
We are continuing to develop more test data for the iEvac® Smoke/Fire Hood and we will add these to our web site as they become available.

Precautions
Of course, no filter and no hood can provide 100% protection, so be sure to follow the instructions in the User Manual.
