SECTION 5 STABILITY AND REACTIVITY
Stability Unstable Conditions to Avoid
Avoid temperatures above 50oC.
Stable X
Incompatibility (Materials and Conditions to Avoid)
Avoid contact with combustable materials, acids, organic materials and reducing agents.
Hazardous Decomposition Products
Thermal decomposition expected to produce chlorine dioxide, chlorates.
SECTION 6 TOXICITY DATA
Short term effects of over exposure when :
In contact with skin : Slightly irritating in contact with skin
In contact with eyes : Liquid causes severe damage, even on short duration.
Vapour causes irritation.
Inhaled : Severe irritant to respiratory system and signs of haemolysis from
0.1 mg/l as NaClO2
Ingested : Harmful if swallowed. LD50/oral/rat 284mg/Kg as NaClO2
Long Term Exposure : Not genotoxic, absence of toxic effects on fertility, foetal development.
SECTION 7 FIRST AID MEASURES
Skin Contact : Remove contaminated clothing and wash affected area
with copious quantities of water.
Eye Contact : Immediately irrigate with water holding eye open if necessary.
Seek medical attention.
Inhalation : Remove patient to fresh air. Keep patient warm and at rest.
Apply oxygen or artificial respiration if needed.
Ingestion : Do not induce vomiting. Give copious quantities of water to drink.
Get medical assistance.
Further Medical Advice : Harmful by ingestion, inhalation skin and eye contact. Local corrosive
effects predominate. No known systemic effects. No specific antidotal
treatment, symptomatic support required. No known delayed effects
apart from consequence of local tissue damage.
