EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS!

Inhalation Cough. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
OILY, COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance is a weak acid. Reacts violently with strong bases and oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.
