TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting.
NO open flames, NO sparks, and NO smoking.
Dry powder. Water may be ineffective.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Burning sensation. Cough. Sore throat. Dizziness. Headache. Nausea. Shortness of breath. Laboured breathing.
Closed system and ventilation.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
 •SKIN Redness. Pain. Skin burns. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain. Blurred vision. Loss of vision. Severe burns.
Face shield or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
 •INGESTION Burns in mouth and throat. Abdominal cramps. Vomiting. Diarrhoea. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING

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

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
On combustion, forms toxic gases including phosgene and hydrogen chloride . The substance decomposes on contact with water producing hydrogen chloride and formaldehyde. Attacks many metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Exposure by all routes should be carefully controled to levels as low as possible A2 (suspected human carcinogen); (ACGIH 2009).
MAK:
Carcinogen category: 1 (applies to the technical product containing up to 7% impurities of dichlorodimethyl ether.)
(DFG 2009).
OSHA PEL: 1910.1006 See Appendix B
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
Serious local effects by all routes of exposure.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is carcinogenic to humans. Lungs may be affected by repeated or prolonged exposure.
