COMBUSTION AND THERMAL DECOMPOSITION PRODUCTS :
Not applicable
EXTINGUISHING MEDIA :
Use extinguishing media appropriate to surrounding fire conditions
*** SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION ***
NOTE : Exposure to this material can be controlled in many
ways. The measures appropriate for a particular
worksite depend on how this material is used and on
the extent of exposure. This general information can
be used to help develop specific control measures.
Ensure that control systems are properly designed and
maintained. Comply with occupational, environmental,
fire, and other applicable regulations.
SAMPLING AND ANALYSIS :
NIOSH METHOD 7300 - NIOSH Manual of Analytical Methods. 4th ed. Vol. 2.
Partially evaluated method for Elements by ICP. Collection on mixed
cellulose ester membrane filter. Analysis by inductively coupled argon
plasma (ICP-AES) Estimated detection limit: 1 ug
Use appropriate instrumentation and sampling strategy (location, timing,
duration, frequency, and number of samples). Interpretation of the sampling
results is related to these variables and the analytical method. Sampling
should be carried out by trained personnel.
RESPIRATORY PROTECTION GUIDELINES :
No specific guidelines are available. Contact chemical manufacturer,
supplier or appropriate government agencies for advice.
RESISTANCE OF MATERIALS FOR PROTECTIVE CLOTHING :
No specific guidelines are available for sodium chloride solid.
Guidelines for sodium chloride, saturated solution (5):
RECOMMENDED (resistance to breakthrough longer than 8 hours): natural
rubber, neoprene, nitrile rubber.
.
Recommendations are NOT valid for very thin natural rubber, neoprene,
nitrile and pvc gloves (0.3 mm or less).
Recommendations are valid for permeation rates reaching 0.1 ug/cm2/min or 1
mg/m2/min and over. Resistance of specific materials can vary from product
to product. Breakthrough times are obtained under conditions of continuous
contact, generally at room temperature. Evaluate resistance under
conditions of use and maintain clothing carefully.
** EXPOSURE GUIDELINES **
* THRESHOLD LIMIT VALUES (TLVs) / AMERICAN CONFERENCE OF
GOVERNMENTAL INDUSTRIAL HYGIENISTS (ACGIH) / 2000 *
TIME-WEIGHTED AVERAGE (TLV-TWA) : Not established
TLV COMMENTS :
NOTE: In many jurisdictions, exposure limits are similar to the ACGIH
TLVs. Since a TLV has not been established for this substance, appropriate
government agencies in each jurisdiction should be consulted to determine
which regulations apply.
* PERMISSIBLE EXPOSURE LIMITS (PELs) / FINAL RULE LIMITS /
U.S. OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) *
TIME WEIGHTED AVERAGE (PEL-TWA) : Not established
NOTE: The OSHA PEL Final Rule Limits are currently
non-enforceable due to a court decision. The OSHA
PEL Transitional Limits are now in force.
* PERMISSIBLE EXPOSURE LIMITS (PELs) / TRANSITIONAL LIMITS /
U.S. OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) *
TIME WEIGHTED AVERAGE (PEL-TWA) : Not established
TRANSITIONAL LIMIT PEL COMMENTS :
Not established
