3. Hazards Identification
Oxidiser; skin and eye hazard, lung toxin
4. First aid measures
Eye contact: Irrigate thoroughly with water for at least 10 minutes. OBTAIN MEDICAL
ATTENTION.
Inhalation:
If person experiences nausea, headache or dizziness, the person should stop work
immediately and move to fresh air until these symptoms disappear. Use support respiration if needed.
Call a physician
Skin contact: Drench the skin thoroughly with water. Remove contaminated clothing and wash before
re-use. Unless contact has been slight, OBTAIN MEDICAL ATTENTION.
Ingestion:
Wash out mouth with water and give plenty of water to drink. DO NOT induce
vomiting. DO NOT give anything by mouth if the person is unconscious or if having convulsions.
OBTAIN MEDICAL ATTENTION.
5. Fire-fighting risks
Special risks:
Cool exposed containers with water
Suitable extinguishing media:
Page 1 Poolchlor granules
On small fires use water spray or fog. On large fires, use heavy deluge or fog streams Do not use dry
extinguishers containing ammonium compounds.
6. Accidental release measures
Spill Mitigation Procedures
Air Release
Water Release
Land Spill
Hazardous concentrations in air may be found in local spill area
and immediately downwind. If spill material is dry, do not put
water directly on this product as a gas evolution may occur. If
material is wet transfer to a suitable container, and contact local
chemical waste disposal company..
Dust/vapours may be suppressed by the use of a water fog.
This material is heavier than water. This material is soluble in
water. Stop flow of material into water source as soon as
possible.Monitor all exit water for available chlorine and pH.
Advise local authorities of any contaminated water release.
Containerise all virgin material in a clean dry container using only
dedicated equipment to clean material up. Containerise all
contaminated material in a clean dry container and remove to a
well ventilated area being sure to not seal tightly. Contaminated
spill material may become a hazardous waste.
Personal Protection for Emergency
Spill & Fire-Fighting Situations
In case of fire, use normal fire fighting equipment as self contained
breathing apparatus. Refer to section 8 for protective equipment in
the event of a spill.
Other
If this material becomes damp/wet or contaminated in a container,
the formation of nitrogen trichloride may occur and an explosive
condition may exist.
7. Handling and Storage
Handling
Do not take internally. Avoid contact with eyes, skin or clothing. Upon contact with
skin or eyes, wash off with water
Storage:
Keep tightly sealed. Store in a clean, dry well ventilated area. Do not store at
temperatures above 60°C
Product Stability and Compatability:
Shelf life limitations
Incompatible materials for packaging
Incompatible materials for storage or transport
Indefinite if stored at room temperature
Paper, cardboard
Other oxidisers, organic materials, reducing
agents, acids, bases.
8. Exposure controls / personal protection
As appropriate to quantity handles.
Respirator:
Chlorine cartridge full face piece respirator with dust/mist prefilter
Ventilation:
Use local exhaust ventilation to minimise dust levels and chlorine gas.
Gloves:
Neoprene rubber or PVC
Eye protection
Goggles or face shield
Other precautions:
Plastic apron, sleeves, boots – if handling large quantities

11. Toxicological information
Harmful if inhaled or ingested. Harmful if exposed to skin and eyes.
Signs, symptoms, and effects of exposure.
Inhalation
Acute exposure may cause: severe irritation to respiratory tract resulting in lung
edema which can result in shortness of breath, wheezing, choking, chest pain
and impaired lung function. Inhalation of high concentrations can result in
permanent lung damage.
Eye
Exposure may cause severe irritation and/or chemical burns with corneal
damage. Impairment of vision is possible.
Skin
Acute exposure can cause severe irritation, and/or chemical burns. Chronic
exposure effects would be similar to those from acute exposure except for
effects secondary to tissue destruction. Prolonged skin exposure may cause
dermis destruction with impaired skin regeneration at the site of contact.
Ingestion
Ingestion can cause irritation and/or chemical burns to the gastro-intestinal tract
characterised by nausea, vomiting, diahorrea, abdominal pain, bleeding and
ulceration. Chronic toxicity via this route is unlikely due to its corrosive nature.
Medical conditions aggravated by exposure: Respiratory, cardiovascular and skin diseases
