TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 93°C explosive vapour/air mixtures may be formed.
Above 93°C use a closed system, ventilation.
Combat fire out of sheltered position.
EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Convulsions. Dizziness. Headache. Vomiting. Weakness. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! Redness. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness. Pain. Blurred vision.
Face shield, 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 Convulsions. Diarrhoea. Dizziness. Headache. Vomiting. Weakness. Unconsciousness.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS VISCOUS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes . Reacts violently with strong oxidants , acids , halogens causing fire and explosion hazard. Attacks rubber, some forms of plastic and coating.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as lead) 0.1 mg/m3; (skin); A4; (ACGIH 2003).
MAK: (as lead) 0.05 mg/m3; skin absorption (H);
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2007).
OSHA PEL: TWA 0.075 mg/m3 skin
NIOSH REL: TWA 0.075 mg/m3 skin
NIOSH IDLH: 40 mg/m3 (as Pb) See: 78002


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the central nervous system , resulting in unconsciousness . Exposure at high levels may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the central nervous system . May cause toxicity to human reproduction or development.

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised that this substance does not enter the environment.

N O T E S

Tetraethyl lead used as an anti-knock compound in gasoline also contains ethylene dibromide and ethylene dichloride as impurities. Depending on the degree of exposure, periodic medical examination is suggested. The relation between odour and the occupational exposure limit cannot be indicated. Do NOT take working clothes home.
