7. HANDLING AND STORAGE
Handling: Avoid inhalation of dust and fumes. Do not take internally. Avoid contact with skin, eyes
and clothing. Upon contact with skin or eyes, wash off with water. Remove contaminated clothing and
wash before reuse.
Storage: Keep product tightly sealed in original containers. Store product in a cool, dry, well
ventilated area. Store away from combustible or flammable products. Keep product packaging clean
and free of all contamination, including, e.g. other pool treatment products, acids, organic materials,
nitrogen-containing compounds, dry powder fire extinguishers (containing mono-ammonium
phosphate), oxidizers, all corrosive liquids, flammable or combustible materials, etc.
Shelf Life Limitations: Do not store product where the average daily temperature exceeds 95
o
F.
Storage above this temperature may result in rapid decomposition, evolution of chlorine gas and heat
sufficient to ignite combustible products. Shelf life (that is, the period of time before the product goes
below stated label strength) is determined by storage time and temperatures. Store in a cool, dry,
well ventilated area. Prolonged storage at elevated temperatures will significantly shorten the shelf
life. Storage in a climate controlled storage area or building is recommended in those areas where
extremes of high temperature occur. Average daily temperature of 35
o
C/95
o
F. Storage above this
temperature may result in rapid decomposition, evolution of chlorine gas and heat sufficient to ignite
combustible products.
Incompatible Materials for Storage: Do not allow product to come in contact with other materials,
including e.g. other pool treatment products, acids, organic materials, nitrogen-containing
compounds, dry powder fire extinguishers (containing mono-ammonium phosphate), oxidizers, all
corrosive liquids, flammable or combustible materials, etc. A chemical reaction with such substances
can cause a fire.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Ventilation: Local exhaust ventilation or other engineering controls are normally required when
handling or using this product to keep airborne exposures below the TLV, PEL or other
recommended exposure limit.
Protection Equipment for Routine Use of Product:
Respiratory Protection: Wear a NIOSH approved respirator if levels above the exposure limits are
possible. A NIOSH approved full-face air purifying respirator equipped with combination
chlorine/P100 cartridges. Air purifying respirators should not be used in oxygen deficient or IDLH
atmospheres or if exposure concentrations exceed (10) times the published limit.
Skin Protection: Wear impervious gloves to avoid skin contact. A full impervious suit is recommended
if exposure is possible to a large portion of the body.
Eye Protection: Use chemical goggles.
Protection Clothing Type: Nitrite, Natural rubber, Neoprene (This includes: gloves, boots, apron,
protective suit)
General Protective Measures: An eye wash and safety shower should be provided in the immediate
work area.
