PMN: 00-7 ENGINEER: Jon/TMB

PV (kg/yr): 

SUBMITTER: Kelco Biopolymers, unit of Monsanto B 

USE: I_--_ 

OTHER USES: None listed 

MSDS: Yes Label: Yes 

General Eqp.: protective gloves/avoid eye contact/natural 

or mechanical.venti1ation to control exposure

levels below airborne exposure limits. The 

use of mechanical ventilation is preferred at 

sources of air contamination. 

Respirator: use NIOSH approved respiratory protection

equipment when airbogne exposure limits are 

exceeded 

Health Effects1 combustible dust/fore-ignbody

irritant/prolonged'contact may cause 

drying or chapping of the skin/excessive

inhalation of dust may be annoying and 

can mechanically impede respiration 

TLV/PEL (PMN or raw mat6rials): 

OSHA PEL 15 mg/m3 (total dust), 5 mg/m3 (regjp. dust)

ACGIH TLV 10 mg/m3 (inhalable), 3 mg/m3 (respirable)
