Section 3: HAZARDS IDENTIFICATION (Cont.)
3.1 POTENTIAL HEALTH EFFECTS
EYE: Contact with the eyes by product mist or solution will cause irritation and a burning sensation. Eye
contact may result in severe corneal injury.
SKIN CONTACT: Contact with product mist or solution will cause skin irritation and may result in corrosion of
the skin.
SKIN ABSORPTION: Absorption is unlikely to occur.
INGESTION: Ingestion of product solution will cause irritation and corrosion of the gastrointestinal tract to
include nausea, vomiting and diarrhea.
INHALATION: Inhalation of product vapors, liquid or mist may produce burns of the respiratory tract.
CHRONIC EFFECTS/CARCINOGENICITY: Not listed as a carcinogen by NTP, IARC or OSHA.
Section 4: FIRST AID MEASURES
4.1 EYES: Immediately flush with large quantities of water for 15 minutes. Hold eyelids apart during irrigation
to insure thorough flushing of the entire area of the eye and lids. Obtain immediate medical attention.
4.2 SKIN: Immediately flush with large quantities of water. Remove contaminated clothing under a safety
shower. Obtain immediate medical attention.
4.3 INGESTION: DO NOT INDUCE VOMITING. If victim is conscious, immediately give large quantities of
water. If vomiting does occur, continue to give fluids. Obtain immediate medical attention.
4.4 INHALATION: Remove victim from contaminated atmosphere. If breathing is labored, administer
oxygen. If breathing has ceased, clear airway and start mouth to mouth resuscitation. If heart has stopped
beating, external heart massage should be applied. Obtain immediate medical attention.
Section 5: FIRE FIGHTING MEASURES
5.1 FLAMMABLE PROPERTIES
FLASH POINT: 201潞F (93.9掳C) METHOD USED: PMCC

Section 5: FIRE FIGHTING MEASURES (Cont.)
5.4 FIRE & EXPLOSIVE HAZARDS: When heated or involved in a fire carbon disulfide and/or
dimethylamine may evolve. These gases may form explosive mixtures with air. (See Section 5.2) Keep
containers/storage vessels in fire area cooled with water spray.
5.5 FIRE FIGHTING EQUIPMENT: Because of the possible presence of toxic gases and the corrosive nature
of the product, wear self-contained breathing apparatus, positive pressure, MSHA/NIOSH (approved or
equivalent) and full protective gear.
Section 6: ACCIDENTAL RELEASE MEASURES
6.1 Small releases: Confine and absorb small releases on sand, earth or other inert absorbent. Neutralize
with a very dilute acid such as acetic acid. Place contaminated product and soil in a suitable container for
disposal.
6.2 Large releases: Confine area to qualified personnel. Wear proper protective equipment. Shut off
release if safe to do so. Dike or divert spill area to prevent runoff into sewers, drains or surface waterways
(potential aquatic toxicity). Recover as much of the solution as possible. Treat remaining material as a small
release (above).
Section 7: HANDLING and STORAGE
7.1 Handling: Handle in enclosed containers to avoid breathing product. Avoid contact with skin and eyes.
Use in a well ventilated area. Wash thoroughly after handling.
7.2 Storage: Store in well ventilated areas in enclosed containers. Do not store combustibles in the area of
storage vessels. Keep away from any sources of heat or flame. Store tote and smaller containers out of
direct sunlight at moderate temperatures [<90潞F (32潞C)]. (See Section 10.4 for materials of construction)
Section 8: EXPOSURE CONTROLS, PERSONAL PROTECTION
8.1 RESPIRATORY PROTECTION: Wear self-contained breathing apparatus, positive pressure,
MSHA/NIOSH (approved or equivalent).
8.2 SKIN PROTECTION: Gloves, boots, and chemical suit should be worn to prevent liquid contact. Wash
contaminated clothing prior to reuse. Contaminated shoes cannot be cleaned and should be discarded
8.3 EYE PROTECTION: Chemical goggles and a full face shield.
8.4 EXPOSURE GUIDELINES: OSHA ACGIH
TWA STEL TLV STEL
8.5 ENGINEERING CONTROLS: Use adequate exhaust ventilation to prevent inhalation of product vapors.
Maintain eyewash/safety shower in areas where chemical is handled.
