Special Remarks on Explosion Hazards:
Anydrous Sodium Hypochlorite is very explosive. Primary amines and calcium hypochlorite or sodium hypochlorite react
to form normal chloroamines, which are explosive. Interaction of ethyleneimine with sodium (or other) hypochlorite gives
the explosive N-chloro cmpd. Removal of formic acid from industrial waste streams with sodium hypochlorite soln becomes
explosive at 55 deg C. Several explosions involving methanol and sodium hypochlorite were attributed to formation of methyl
hypochlorite, especially in presence of acid or other esterification catalyst. Use of sodium hypochlorite soln to destroy acidified
benzyl cyanide residues caused a violent explosion, thought to have been due to formation of nitrogen trichloride. (Sodium
hypochlorite)
Section 6: Accidental Release Measures
Small Spill:
Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container.
Large Spill:
Corrosive liquid. Oxidizing material. Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material.
Do not get water inside container. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance
damp using water spray. Do not touch spilled material. Use water spray curtain to divert vapor drift. Prevent entry into sewers,
basements or confined areas; dike if needed. Call for assistance on disposal. Be careful that the product is not present at a
concentration level above TLV. Check TLV on the MSDS and with local authorities.
Section 7: Handling and Storage
Precautions:
Keep locked up.. Keep container dry. Keep away from heat. Keep away from sources of ignition. Keep away from combustible
material.. Do not ingest. Do not breathe gas/fumes/ vapor/spray. Never add water to this product. In case of insufficient
ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or
the label. Avoid contact with skin and eyes. Keep away from incompatibles such as reducing agents, combustible materials,
organic materials, metals, acids.
Storage:
Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies, reducing agents
and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers. Air Sensitive Sensitive to light. Store in
light-resistant containers.
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective
threshold limit value.
Personal Protection:
Face shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Boots.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
product.
Exposure Limits:
Sodium hypochlorite TWA: 1 CEIL: 1 (ppm as Cl2) STEL: 1 (ppm as Cl2) from ACGIH (TLV) [United States] Sodium hydroxide
STEL: 2 (mg/m3) from ACGIH (TLV) [United States] TWA: 2 CEIL: 2 (mg/m3) from OSHA (PEL) [United States] CEIL: 2 (mg/
m3) from NIOSH Consult local authorities for acceptable exposure limits.
