SODIUM HYPOCHLORITE
7 HANDLING AND STORAGE
Safety: Keep out of reach of children. Do not mix with other
chemicals, fuels or solvents.
Risk: Contact with acids liberates toxic gas. Corrosive.
Storage and Transport: Store in a cool, dry place that is well-
ventilated and away from foodstuff containers. Direct sunlight
should be avoided.
Incompatibility (Materials to avoid for purposes of transport,
handling and storage only): Avoid storage with acids, oxidising
agents, reducing agents, metals and metallic salts. Class 8
Corrosives shall not be loaded with other Dangerous Goods of
Classes 1, 4.3, 5.1, 5.2, 7 or 8 (acids only) or with foodstuffs.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure Standards: None assigned for mixture.
Atmospheric Contaminant Exposure Standard for:
Chlorine: CAS No.7782-50-5 TWA = 1ppm (3 mg/cu.m)
STEL= Peak limitation same as
TWA
[Source: Safe Work Australia HSIS-2011]
Engineering Controls: Mechanical Ventilation: Not required
under normal conditions, but local exhaust ventilation should
be used to control any air contaminants to within the Exposure
Standards.
Personal Protection:
Gloves - Wear rubber, neoprene or nitrile gloves.
Note: Resistance of glove materials can vary. Evaluate
resistance under conditions of use and maintain PPE
carefully.
Eye-protection - Safety glasses should be worn.
Respiratory - If inhalation risk exists, a suitable cartridge type
Respirator should be worn.
Other - Protective overalls are desirable. An eyewash unit
should be available. Always work in a well ventilated area.

10 STABILITY AND REACTIVITY
Stability: Stable. However, heat, light, contamination with acids
or contact with metal surfaces may promote the formation of
toxic chlorine gas.
Sodium Hypochlorite is corrosive to aluminium, zinc and tin. It
can burn holes in clothes and cotton mops
Hazardous polymerization: Will not occur.
11 TOXICOLOGICAL INFORMATION
Health Effects:
Acute
Swallowed: Irritating to the gastro-intestinal tract, may cause
nausea and vomiting.
Eye: Eye contact may result in burns that could be permanent.
Skin: Principal route of exposure is usually by skin contact.
Repeated or prolonged skin contact may cause swelling,
redness, blistering or dermatitis. Sodium Hypochlorite acts as
a skin sensitiser and may burn sensitive skin. It is not
absorbed through the skin.
Inhaled: Can result in coughing and respiratory difficulty. The
vapour if concentrated may irritate the lungs. If reaction
occurs to liberate chlorine (such as accidental admixture with
acids), self-contained or air-supplied breathing apparatus will
be required.
Health Effects -
Chronic
: none known.
Toxicity data: No chronic effects known to occur as material is
inactivated by tissue and blood serum.
