EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!

Inhalation
Local exhaust or breathing protection.
Fresh air, rest.
Skin
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain. Severe deep burns.
Safety goggles, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal pain. Burning sensation.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention. Rest.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Then remove to safe place. (Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust.)

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR COLOURLESS VISCOUS HYGROSCOPIC LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes. The solution in water is a medium strong base. Reacts violently with strong oxidants, strong acids. Attacks copper, zinc, aluminium, and their alloys.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 mg/m; (skin); (ACGIH 2002).
MAK: class Carcinogen category: 3A; Sh, H (2002).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver and kidneys.
