3. HAZARDS IDENTIFICATION OF THE PREPARATION
HARMFUL
On contact with moisture, NaDCC readily decomposes to Chlorine, Hypochlorous Acid & Cyanuric Acid. Health Effects
of Tablet (NOT resultant solution)
Effect on Skin: Irritation and burning
Effect on Eyes: Irritation and burning
Effect on Ingestion: Harmful if swallowed. Nausea, headache, vomiting & upper abdominal pain.
Effect On Inhalation Unlikely route of exposure unless tablet breaks into powder, then material may be irritant to
mucous membranes

4. FIRST AID MEASURES
Eye Contact: Immediately flush with plenty of clean water for at least 15 minutes. If irritation
persists, seek medical attention.
Skin Contact: Promptly wash thoroughly with water for at least 15 minutes while removing
contaminated clothing. Wash any contaminated clothing well before re-use.
Ingestion: Immediately rinse mouth, then drink plenty of water or milk. Do not induce
vomiting. Seek medical attention.
Inhalation: Move to fresh air. If irritation persists, seek medical attention.

5. FIRE-FIGHTING MEASURES
Special Fire or Explosion Hazards
Product is not flammable itself, but contact with combustible material may cause fire. Product combustible if dehydrated by
drying. Decomposes above 250OC with release of chlorine & other toxic fumes.
A thermal decomposition can be extinguished by flooding with copious amounts of water or by isolating the decomposing
material in open air and allowing it to be consumed. Use self contained breathing apparatus and goggles. Do not approach
from leeward.
Suitable Extinguishing Media: Pressurised water or dry powder. Do not use dry fire extinguishers containing ammonium
compounds.
Other Recommendations: Remove the product if it is safe to do so, before using water for fire fighting, in order to minimise
hazards from release of toxic fumes. It will often be safer to let the fire burn itself out. Where it is decided to fight the fire with
water, large quantities must be used. If insufficient water is used there may be an explosion hazard associated with hot damp
material.

6. ACCIDENTAL RELEASE MEASURES.
Any spillage鈥檚 should be cleaned up as soon as possible to prevent contamination with foreign materials with which it may
react - see section 10, stability and reactivity.
Handle spillage carefully, do not return spilled material to original container. If tablets are dry and uncontaminated, collect
up into heavy-duty plastic bag; where possible and suitable, use material as originally intended. Wash away any residues with
copious amounts of water.
If tablets are contaminated they should be transferred to waste ground, spread thinly and covered with a thin layer of earth; a
smell of chlorine will be noted until the material has degraded. Keep people, vehicles and animals away from the disposal area.
If tablets become damp they will effervesce, evolving carbon dioxide and may decompose to give off chlorine fumes;
transfer spillage to unsealed plastic bags avoiding any large masses of material within the bags and remove to waste ground for
immediate treatment/disposal as above; avoid breathing fumes. Wash away residues with copious amounts of water.
If spillage of tablets is large (more than 100Kg), place into bins lined with polythene bags and eliminate in accordance with
locally valid disposal regulations

7. HANDLING AND STORAGE.
Recommended Storage Conditions
Store away from all incompatibles and combustibles (see section 10). Store in a cool, dry, well ventilated place. Moisture
sensitive. Avoid high humidity levels. Do not allow water to get into container. Keep away from fire, heat, flame & direct
sunlight. Keep container tightly closed. Keep out of reach of children. Never store damp or contaminated material.
Recommended Handling Precautions
Avoid contact with eyes, skin & clothing.
When handling large quantities of tablets, wear chemical resistant gloves and safety goggles.
Avoid breathing any dust.
Wash thoroughly after handling.
Use protective equipment recommended in section 8.
Do not eat, drink or smoke when handling this material.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Occupational Exposure Limits (EH40/2000): Long Term Exposure Limit to Chlorine 鈥? (8 hours TWA) 0.5ppm
1.5mgm-3
Short Term Exposure Limit to Chlorine 鈥? (10 minutes) 1ppm
2.9mgm-3

Respiratory Protection: Where any dust in the breathing zone cannot be controlled with ventilation, wear an
officially approved respirator (NIOSH/MSHA or equivalent agency) for protection
against airborne dust.
Ventilation: Use local exhaust ventilation where appropriate
Eye Protection: If airborne dust concentrations are high, wear appropriate protective goggles. Wash
eyes with clean water where there is potential eye contact.
Skin Protection: When handling large bulk quantities wear protective gloves.
Wash immediately if skin is contaminated. Remove and wash contaminated
clothing and clean up equipment before re-use.
Wash thoroughly with soap and water after handling

9. PHYSICAL AND CHEMICAL PROPERTIES
Appearance: White flat bevelled tablet
Odour: Characteristic Chlorine Odour
pH: As is - not applicable
pH: In solution - 5.0 - 6.0 approx.
Solubility: Freely soluble
Oxidising Properties: Non oxidising
Flash Point: Not flashing
Flammability: Not flammable
Autoflammability: Not autoflammable
Explosion Properties: Not explosive

10. STABILITY AND REACTIVITY
Conditions to Avoid
Do not store on or near heat sources or naked flame. Avoid moisture. NaDCC decomposes at temperatures above 240OC
liberating toxic gases.
Materials to Avoid
Contact with water liberates chlorine and with nitrogen compounds may cause explosion. Avoid organic materials, oils,
grease, sawdust, reducing agents, nitrogen containing compounds, calcium hypochlorite, other oxidizers, acids, alkalis,
cationic and certain non-ionic surfactants.

11. TOXICOLOGICAL INFORMATION
Route of entry: Inhalation, skin contact & ingestion.
Inhalation of NaDCC is irritating to the nose, mouth, throat and lungs.
Ingestion of NaDCC can cause irritation and or/burns to the gastrointestinal tract.
Skin & Eye Contact: with NaDCC can cause severe irritation and/or burns, characterized by redness, swelling and scab
formation. May cause impairment of vision and corneal damage.
Toxicological Data: NaDCC
Acute toxicity
Oral LD50 (rat) ca. 1825mg/kg
Eye Irritation (rabbit) Severe irritant
Rabbit dermal LD50 >20,000mg/kg
Carcinogenicity
This chemical is not considered to be carcinogenic by any reference source.

12. ECOLOGICAL INFORMATION
NaDCC is highly toxic to fish. Do not discharge into lakes, ponds, streams or public water unless in accordance with the
permit of official regulations.

13. DISPOSAL CONSIDERATIONS
Disposal should be done in accordance with all official regulations. If material is dry, incineration is recommended.
