***************** IV - HEALTH EFFECTS INFORMATION (continued) *********
EFFECTS OF OVEREXPOSURE
No information found for this material. Based on the available animal
toxicity information for similar products, it is anticipated that this
material will produce moderate skin and eye irritation. Upon prolonged
contact, burns and possible irreversible damage may be produced.
Repeated or prolonged contact may induce skin or lung sensitization.
Mists or vapors may be irritating to the respiratory tract.
OVEREXPOSURE MAY AGGRAVATE EXISTING CONDITIONS:
Bronchial asthma, eczema or other allergic conditions.
EMERGENCY AND FIRST AID PROCEDURES:
Eyes:
Flush eyes with large amounts of running water for at least 15 minutes.
Hold eyelids apart to ensure rinsing of the entire surface of the eye
and lids with water. Get immediate medical attention. If physician not
available, flush for additional 15 minutes and then transport victim to
medical care.
Skin:
Wash affected areas with plenty of water, and soap if available, for
several minutes. Remove and clean contaminated clothing and shoes. Seek
medical attention if irritation develops.
Ingestion:
If swallowed, immediately give 3-4 glasses of water. DO NOT induce
vomiting. If vomiting occurs, give fluids again. Get immediate medical
attention. Have physician determine if patient's condition allows
induction of vomiting or evacuation of stomach. Do not give anything by
mouth to an unconscious or convulsing
person.
Inhalation:
Remove from area to fresh air. If not breathing, clear airway and start
artificial respiration. If victim is having trouble breathing, give
supplemental oxygen, if available. Get immediate medical attention.

****************** VI - SPILL AND DISPOSAL INFORMATION*****************
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Caution! Floors may become slippery. Wear appropriate protective gear
and NIOSH/MSHA approved respirator where mists or vapors of unknown
concentrations may be generated (self-contained breathing apparatus
preferred).
Dike and contain spill with inert material (sand, earth, etc.). Transfer
the liquid and solid separately to containers for recovery or disposal.
Wet residue with water and absorb with inert material (sand, earth...)
and transfer into appropriate containers for disposal. Keep spill out of
sewers and open bodies of water.
WASTE DISPOSAL METHODS
Dispose of in compliance with all Federal, state and local laws and
regulations. Incineration is the preferred method.
****************** VII - PERSONAL PROTECTION INFORMATION***************
VENTILATION TYPE
In processes where mists or vapors may be generated, proper ventilation must be
provided in accordance with good ventilation practices.
RESPIRATORY PROTECTION
In processes where mists or vapors may be generated, a NIOSH/MSHA jointly
approved respirator is advised in the absence of proper environmental controls.
PROTECTIVE GLOVES
Rubber or plastic, when needed, to prevent skin contact.
EYE PROTECTION
Wear chemical goggles where there is a potential for eye contact. Use safety
glasses with side shields under normal use conditions.
OTHER PROTECTIVE EQUIPMENT
Eye wash; safety shower; protective clothing (long sleeves, coveralls or
other, as appropriate), when needed, to prevent skin contact.
