 Health:

 Health Summary: Absorption is nil through the skin based on 

physical/chemical properties and good through the lungs and GI tract based on analogs. There is 

concern for irritation by analogy to which is corrosive to 

the eyes but is not a dermal irritant. There is uncertain concern for mutagenicity also by analogy 

to which gave a weak positive for chromosome aberrations in human lymphocytes but 

is negative in an oral mouse micronucleus assay and negative in Salmonella and E coli. The 

NOEL for from a 28-day oral study in rats is 30 mg/kg (LOEL = 150 mg/kg) based on 

degeneration of the kidneys, necrosis of the heart muscle, and effects to the male reproductive 

organs. Cesium has been shown to cause cardiac problems and developmental toxicity. Low 

moderate concern.

Generated by the 06/07/2005 version of ChemSTEER. PMN

import only -> Mfg no assessed. Tech contact not

available via phone. The submission provides no

information on the potential processing and use of PMN

after import; therefore, a same submitter, similar use

Exposure to Particulate (Class I)

Typical: 1.1E+0 mg/day over 200 days/yr

(typical) to 7.2 mg/day (worst-case).

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

INITIAL REVIEW ENGINEERING REPORT 

PMN: 11-0546

Use: Brazing of parts/component manufacture

Number of Sites/ Location: 2

unknown site(s)

Days/yr: 250

Basis: P-02-0025: 10 - 15 customer sites, 250 day/yr use

for 9 formulators (1 - 1.5 customers/ formulator). For

this case, assume 2 customers.

Process Description: (From Foster, 2001): (OEM

facilities) - The metal coated parts to be braized (e.g.,

aluminum heat exchangers), are loaded onto a conveyor and

first enter vented metal enclosures beginning with a

thermal degreaser/washer, then to the fluxer application

(application of braizing coating), then into a dryer to

remove moisture followed by the braising furnace and

primary and secondary cooling chambers. The metal parts

are coated with the flux, heated to temperatures of 435

to 480 deg. C at which the flux melts to form the bond

between the parts.

ENVIRONMENTAL RELEASES ESTIMATE SUMMARY

PMN chemical is fused onto the metal parts as a result of

the braising operation. Aside from residual in packaging,

process releases not expected, per past case P02-0025.

Incineration or Landfill

Conservative: 9.0E-2 kg/site-day over 250 days/yr from 2

sites

EPA SANITIZED Page 10 of 22
or 4.5E+1 kg/yr

to: industrial waste disposal (water not expected for

this process)

from: Cleaning Solid/ Powder Residuals from Containers

Used to Transport the Raw Material

basis: EPA/OPPT Solid Residuals in Transport Containers

Model, CEB standard 1% residual.

RELEASE TOTAL

4.5E+1 kg/yr - all sites

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 6

Basis:

Inhalation:

Expected to be negligible. // Inhalation exposure is not

expected from the braising operation. The intended use

of the PMN chemical is to form the bond between metal

parts so the great majority will end up on the parts.

Vapors from the furnace and primary and secondary cooling

chambers are not expected to be open to the workplace

environment (as per Foster, 2001)

Exposure to Particulate (Class I)

Typical: 4.3E-1 mg/day over 250 days/yr

Worst Case: 1.4E+0 mg/day over 250 days/yr

Number of workers (all sites) with inhalation exposure: 6

Basis: Unloading Solid Raw Material from Transport

Containers; EPA Small Volume Handling Model, less than 54

kg of PMN handled per site-day. Assume 3 workers/ site

max exposed during this activity.

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release 

activity labels.Multiple release activities are combined in one exposure scenario if their releases occur at 

same location. 

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and 

Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure 

scenario.CC is the aquatic concentration of concern. 

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily
