Section 3 - HAZARDS IDENTIFICATION
damaging to the health of the individual, following ingestion, especially where
pre-existing organ (e.g. liver, kidney) damage is evident. Present definitions
of harmful or toxic substances are generally based on doses producing mortality
(death) rather than those producing morbidity (disease, ill-health).
Gastrointestinal tract discomfort may produce nausea and vomiting. In an
occupational setting however, unintentional ingestion is not thought to be cause
for concern.
EYE
Although the liquid is not thought to be an irritant, direct contact with the
eye may produce transient discomfort characterized by tearing or conjunctival
redness (as with windburn).
SKIN
The material is not thought to produce adverse health effects or skin irritation
following contact (as classified using animal models). Nevertheless, good
hygiene practice requires that exposure be kept to a minimum and that suitable
gloves be used in an occupational setting.
INHALED
Not normally a hazard due to non-volatile nature of product.
The material is not thought to produce adverse health effects or irritation of
the respiratory tract (as classified using animal models). Nevertheless, good
hygiene practice requires that exposure be kept to a minimum and that suitable
control measures be used in an occupational setting.
CHRONIC HEALTH EFFECTS
Long-term exposure to the product is not thought to produce chronic effects
adverse to the health (as classified using animal models); nevertheless exposure
by all routes should be minimized as a matter of course.
Section 4 - FIRST AID MEASURES
SWALLOWED
- Immediately give a glass of water.
- First aid is not generally required. If in doubt, contact a Poisons
Information Center or a doctor.
EYE
If this product comes in contact with eyes:
- Wash out immediately with water.
- If irritation continues, seek medical attention.
- Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If skin or hair contact occurs:
- Flush skin and hair with running water (and soap if available).
- Seek medical attention in event of irritation.
INHALED
- If fumes or combustion products are inhaled remove from contaminated area.
- Other measures are usually unnecessary.

NOTES TO PHYSICIAN
Treat symptomatically.
Section 5 - FIRE FIGHTING MEASURES
Flash Point (F): Not Applicable
Lower Explosive Limit (%): Not Applicable
Upper Explosive Limit (%): Not Applicable
Autoignition Temp (F): Not Applicable
EXTINGUISHING MEDIA
The product contains a substantial proportion of water, therefore there are no
restrictions on the type of extinguishing media which may be used. Choice of
extinguishing media should take into account surrounding areas.
Though the material is non-combustible, evaporation of water from the mixture,
caused by the heat of nearby fire, may produce floating layers of combustible
substances.
In such an event consider:
- foam
- dry chemical powder
- carbon dioxide.
FIRE FIGHTING
- Alert Emergency Responders and tell them location and nature of hazard.
- Wear breathing apparatus plus protective gloves for fire only.
- Prevent, by any means available, spillage from entering drains or water
course.
- Use fire fighting procedures suitable for surrounding area.
- Do not approach containers suspected to be hot.
- Cool fire exposed containers with water spray from a protected location.
- If safe to do so, remove containers from path of fire.
- Equipment should be thoroughly decontaminated after use.
GENERAL FIRE HAZARDS/HAZARDOUS COMBUSTIBLE PRODUCTS
- Non combustible.
- Not considered to be a significant fire risk.
- Expansion or decomposition on heating may lead to violent rupture of
containers.
- Decomposes on heating and may produce toxic fumes of carbon monoxide (CO).
- May emit acrid smoke.
Decomposition may produce toxic fumes of, carbon dioxide (CO2), other pyrolysis
products typical of burning organic material.
FIRE INCOMPATIBILITY
None known.
PERSONAL PROTECTION
Glasses:
Chemical goggles.
Gloves:
When handling larger quantities:
General purpose rubber glove.

- If contamination of drains or waterways occurs, advise emergency services.
ACUTE EXPOSURE GUIDELINE LEVELS (AEGL) (in ppm)
AEGL 1: The airborne concentration of a substance above which it is predicted
that the general population, including susceptible individuals, could
experience notable discomfort, irritation, or certain asymptomatic nonsensory
effects. However, the effects are not disabling and are transient and
reversible upon cessation of exposure.
AEGL 2: The airborne concentration of a substance above which it is predicted
that the general population, including susceptible individuals, could
experience irreversible or other serious, long-lasting adverse health effects
or an impaired ability to escape.
AEGL 3: The airborne concentration of a substance above which it is predicted
that the general population, including susceptible individuals, could
experience life-threatening health effects or death.
EMERGENCY RESPONSE PLANNING GUIDELINES (ERPG)
The maximum airborne concentration below which it is believed that nearly all
individuals could be exposed for up to one hour WITHOUT experiencing or developing
life-threatening health effects is:
water 500 mg/m鲁
irreversible or other serious effects or symptoms which could
impair an individual's ability to take protective action is:
water 500 mg/m鲁
other than mild, transient adverse effects
without perceiving a clearly defined odour is:
water 500 mg/m鲁

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
The local concentration of material, quantity and
conditions of use determine the type of personal
protective equipment required.
Use appropriate NIOSH-certified respirator based on informed professional
judgement. In conditions where no reasonable estimate of exposure can be
made, assume the exposure is in a concentration IDLH and use NIOSH-certified
full face pressure demand SCBA with a minimum service life of 30 minutes, or
a combination full facepiece pressure demand SAR with auxiliary self-contained
air supply. Respirators provided only for escape from IDLH atmospheres shall be
NIOSH-certified for escape from the atmosphere in which they will be used.
ENGINEERING CONTROLS
General exhaust is adequate under normal operating conditions. If risk of
overexposure exists, wear an approved respirator. Correct fit is essential to
obtain adequate protection. Provide adequate ventilation in warehouse or closed
storage areas.
