PAA

Slide5

History

Slide6

PAA first registered in the U.S. as a pesticide for use as a disinfectant, sanitizer, and sterilant in 1985.

FDA approved for direct contact with food, food processing equipment and utensils, and other food contact surfaces (

21 C.F.R. § 178.1010,

April 1, 2011

Slide7

Occupational

Health

Considerations

Slide8

OSHA—No PEL, but other standards do exist. Thus, agency has issued Rapid Response letters and citations under the General Duty Clause, for what it deems to be high exposures.

Cal/OSHA—Proposed:  0.15 ppm (8

hr

TWA); 0.4 ppm (15 min STEL)

NIOSH—No REL, but proposed IDLH of 0.64 ppm

ACGIH TLV—0.4 ppm as a 15-min STEL

Slide9

Chemical

Properties

Slide10

Anhydrous peracetic acid explodes violently upon heating

PAA sanitizers created by combining aqueous acetic acid and hydrogen peroxide

Equilibrates to solution containing peracetic acid, acetic acid, and hydrogen peroxide

Breaks down rapidly in air

Slide11

Gas Detection Challenges

Slide12

PAA unstable in air, so calibration standard must be generated on-the-fly

This stream must then be analyzed using wet chemistry

Now, you have a standardized calibration source;

good for two hours

DPD (N, N-diethyl-p-phenylenediamine) method: PAA oxidizes

iodide to iodine; iodine oxidizes DPD forming pink product

Slide13

True field calibration is impractical— but a good PAA bump test can be supplied

A suitable PAA solution, activated with a bubbler generates a

gas stream. User refers to calibration chart, by temperature

and flow rate.

Pre-calibrated sensors are delivered to user on a scheduled

basis. Nothing to send back to factory.Best solution is our SENSOR EXPRESS® program
