SCOPE OF WORK: 

BASF CORPORATION 

889 VALLEY PARK DRIVE 

SHAKOPEE, MINNESOTA 

DECEMBER 6, 20ll 

Jan Koehn, M.S .• CIH, Inc. or JK, Inc. was contracted to perform industrial hygiene 

consulting work for BASF Corporation Construction Chemicals for Building Systems research 

and development facility located at 889 Valley Park Drive in Shakopee, Minnesota during July 

2011. The requested professional consulting services involved specified airborne monitoring 

related to defined potential exposure testing scenarios for the identified chemical hazards of 

methylene bisphenyl isocyanate (MDI) or toluene diisocyanate (TDI). A combination ofoutlined 

personal and atea industrial hygiene monitoring to document various defined airborne 

exposures to the identified chemical hazards (i.e. MDI and/or TDI) was undertaken based on a 

provided sampling strategy involving various product application scenarios. Comparison of the 

monitoring results obtained to the current threshold Limit Values (TLVs) published by the 

American COnference of Governmental Industrial Hygienists (ACGIH) as well as good industrial 

hygiene practices was completed. The project work activities were outlined as follows: 

1. Discuss a defined industrial hygiene sampling strategy for identified proposed 

exposure testing scenarios (4) involving the outlined chemical hazards (i.e. MDI 

and/or TDI) for the specified isocyanate-containing products (2 sealants andl surface 

basecoat) related to standard anticipated application procedures for the building 

cons~tion industry within the BASF research and development facility, 

2. Review the outlined sampling strategy with facility EHS and project personnel and 

coordinate the on-site airborne isocyanate monitoring effort involving specified 

activities during a scheduled work day in July 2011, 

3. Conduct requested personal and area exposure monitoring for identified chemical 

hazards involving the outlined product application an~ testing scenarios specified by 

the Client's representatives in accordance with defmed local site conditions as directed 

by the research and development group and complete site recordkeeping,

SCOPE OF WORK: (oontinued) 

4. Provide collected industrial hygiene samples following outlined field desorption to 

EHS personnel for return shipment to the BASF Corporation laboratory in 

Wyandotte, MI for .routine sample analysis by a fapility accredited by the American 

Industrial Hygiene Association (AIHA), and 

5. Prepare a subsequent project summary isocyanate monitoring report for the Client. 

METHODOLOGY: 

An outlined sampling strategy for BASF Corporation Construction Chemicals was 

discussed with Jan Koehn, M.S., CIH of JK, Inc. including direct input from the Client's 

representatives related to the defmed airborne sampling strategy for isocyanate& associated with 

application of sealants and/or a surface coating product involving standard building system use. 

Based on discussions with the Client's representatives regarding the potential for airborne 

exposures to the specified chemical hazards related to standard product· application, review of 

current workplace exposure standards and guidelines, use of a developed isocyanate sampling 

and analytical method, and good work practices and procedures, a project site-specific 

industrial hygiene sampling strategy was outlined for review to complete the exposure testing 

scenarios for the defined monitoring scope of work. This airborne sampling strategy addressed 

a combination of representative personal as well as general area samples for specifi~d potential 

workplace chemical hazards (i.e. MDI and/or TDI) during defined separate product application 

procedures including short-term (15 minutes) and partial period (1 hour) time intervals 

involving 3 products and 4 separate scenarios. Three consecutive replicate sample sets were 

collected for each defmed exposure testing scenario as directed by BASF project personnel. 

Airborne samples were collected in accordance with the defined project sampling 

strategy at the BASF research and development facility on July 14, 2011. The referenced 

industrial hygiene sampling and analytical methods for the identified chemical components (i.e. 

MDI and/or TDI) was OSHA 47/42 involving use of cah'brated pumps from JK, Inc. and 

provided sample media as 13 mm treated filter cassettes from the Client's laboratory. 

Short -term personal as well as partial period work area monitoring was completed 

during specified product application scenarios in accordance with the defmed BASF exposure 

testing airborne sampling ·strategy for the identified isocyanate components as performed by 

project personnel at the research and development site locations. The scenarios were as 

follows: horizontal application of the So no guardTM Basecoat in an ambient environment; 

gunning cards with Sonolasticnx NPl product in the lab; use of Sonolastic NPl and MOlBased Construction Adhesive products, respectively in an allocated 6' x 6' constricted space; and, 

Sonolastic NPl and MDI-Based Construction Adhesive application, respectively within an office space to 

simulate a typical 10' x 12' residential room. The 6' x 6' constricted space scenario was 

designed to simulate an extreme "worst-case" situation. According to BASF applications 

experts, typically, no more than 2 - 3 units of 10 fl oz. cartridges would be used in a confined 

space. However, in this case, 7 - 10 cartridge units were applied in the allotted time without 

any specific further ventilation provided. 

JK, Inc. Report#: 111-11 -2-
SANITIZED VERSION 

METHODOLOGY: (continued) 

SKC personal sampling pumps were pre- and post-calibrated with a primary standard 

and adjusted to the ·appropriate flow rates recommended for air sample collection of the 

identified isocyanate substances for the defined time intervals based on the developed sampling 

strategy. Appropriate media (i.e. prepared 13 mm treated filter cassettes) was used to collect 

representative industrial hygiene airborne monitoring samples based on .the defined product 

application scenarios as outlined by the Client's representatives. Short-term breathing zone 

personal samples were obtained for 15 minutes during direct product application for each 

defined scenario and partial period general area samples were also separately collected for a 

time interval of one hour adjacent to the application area location. A defined airborne sample 

field desorption procedure was employed by the Consultant as provided by the Client's 

representative in accordance with· the referenced industrial hygiene sampling and analytical 

method. Appropriate field blaiik samples for chemical components were also prepared for 

laboratory analysis to address standard quality control considerations. Use of personal 

protective equipment was also subsequently observed as employed by BASF project personnel. 

RESULTS AND DISCUSSION: 

Appendix 1 presents information about JK, Inc. personnel involved in performance of 

this exposure monitoring project. Appendix 2 contains the Client-provided isocyanate 

exposure testing scenarios for defined products and specified application methods at site 

locations. Appendix 3 presents a data summary of the project industrial hygiene airborne 

monitoring results based on the outlined sampling strategy. Appendix 4 contains the lab 

analytical result documentation from the BASF industrial hygiene laboratory. Appendix 5 

presents some digital photographs of the various application scenarios and site locations 

associated with completion of the defined airborne industrial hygiene monitoring effort. 

Personal monitoring was performed for a defined 15-minute time interval located within 

the breathing zone of the BASF technician completing outlined product application based on 

the specified exposure testing scenarios. An adjacent work area sample was collected for a 

time interval of one hour within the outlined general .area location directly adjacent to the 

application process. Three consecutive airborne isocyanate monitoring efforts were conducted 

in order to obtain replicate samples for each defined exposure testing scenario. Clean-up and 

removal of the applied product from each site exposure monitoring location was addressed 

after an elapsed time of one hour inCluding collection, processing, and field desorption of the 

air samples with subsequent set-up of the defined location for the next scenario application 

effort and allowance for some air exchange in the specified work area. 

JK, Inc. Report#: 111-11 -3-

RESULTS AND DISCUSSION:. (contintled) 

MDI-Based Construction Adhesive - Qen:er~Iy, nqn-:detectable <reSUlts were noted for 

MDI associated with the two exposure scenarios involving MDJ.,Based Construction Adhesive product 

application· either ·in. a constricted space or an office location; .Limited detectable results for 

2,6.:.TDI were also noted for the ar~a samples ranging from 0 .. 67 to 1.5 ppb associated with PL 

MDI·Based Construction Adhesive product application within the constricted space, According to BASF 

personnel, the MDI-Based Construction Adhesive product doe.s not contain TDI. compared to the 

Sonolastic NP-1 product which does have this component; therefore, it was stated that the most 

likely reason for the reported presence of TDI is that the confmed space room maY not have 

been given sufficient time for air exchange after further monitoring in the same room following 

use of the Sonolastic NP-1. The scenario involving "gunning cards .. in the lab also did not 

report the detectable presence of either 2,4..:TDI or 2,6-TDI. 

Sonoguard Basecoat · Results - Horizontal application of the Sonoguard Basecoat 

product performed in the outdoor ambient environment reported non-detectable results for both 

2,4-TDI and 2,6-TDI for the personal samples. The area samples, taken at a 1 to 2 foot range 

from the actual application, reported a single detectable result of 0.43 ppb 2,4-TDI and also 

area monitoring resu•ts ranging from 0.35 to 15 ppb based on an airborne exposure for a one 

hour time interval. The highest area result was obtained for the ambient application sample 

location directly on the ground that was positioned closer to the inside comer intersection of 

the BASF facility buildings outside the rear loading dock with increased winds noted. 

Sonolastic NP-1 Results - For these product application scenarios involving either the 

office or constricted space, respectively, all results for 2,4-TDI were reported as not detected 

(ND). A range of generally detectable results for 2,6-TDI was reported both for the personal 

breathing zone and adjacent area samples up to 1.5 ppb for the office space location associated 

with product application. For these applications, a range of 7 - 10 units of the 10 fl oz. 

cartridges were employed compared to a typical use of 2 - 3 units for a similar application 

within these further restricted work areas. Slightly higher 2,6-TDI results were reported for 

use of the same product within a constricted space. The results for this scenario were as 

follows: personal sample results between 1.6 to 3.7 ppb; and, area sample results ranging 

from 2. 7 to 7.8 ppb. Only these final area results based on a one-hour sample collection 

period approach or may exceed the published ACGIH TLV of 0.005 ppm for TOI [as an 8-

hour Time Weighted Average (TWA)]. The personal samples for the TDI components do not 

approach or exceed the published ACGIH TLV - STEL of 0~02 ppm or 20 ppb. 

These levels are substantially below the OSHA Ceiling Limit of 0.02 ppm and the 

ACGIH TLV of 0,005 ppm as an 8-hour Time Weighted Average (TWA). NIOSH also 

publishes two Recommended Exposure Limits (RELs) of 0.005 ppm as an 8-hour TWA and a 

Ceiling Limit of 0.02 ppm based on a 10 minute time interval. The reported sample results for 

the defined scenarios employing limited sampling time intervals were substantially below 

published occupational exposure standards and recommended technical guidelines. All 

industrial hygiene monitoring results are presented in Appendix 3 and· a s~arate technical data 

summary related to the different exposure scenarios is also included below.
