| Gefahrenübersicht | Possible frostbite from contact with liquid[NIOSH] MAPP gas is an explosive hazard. Reduce hazard by keeping concentrations below 10% of lower explosive limit (3400 ppm). It can cause anesthetic effects and at very high concentrations, asphyxiation. At an exposure level of 5000 ppm 7 hours/day, 5 days/week, experimental animals show decreased body weight. [ACGIH] Classified as Simple asphyxiant[CAMEO] Methylacetylene-propadiene mixture, stabilized (UN1060) has warning of explosive polymerization[ERG 2016] See Methylacetylene and Propadiene. |

| Hazardous Reactivities and Incompatibilities | Strong oxidizers, copper alloys [Note: Forms explosive compounds at high pressure in contact with alloys containing more than 67% copper.] |
| Erste Hilfe | (General first aid procedures)Eye: Frostbite - If eye tissue is frozen, seek medical attention immediatelyif tissue is not frozen, immediately and thoroughly flush the eyes with large amounts of water for at least 15 minutes, occasionally lifting the lower and upper eyelids. If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible.Skin: Frostbite - Compressed gases may create low temperatures when they expand rapidly. Leaks and uses that allow rapid expansion may cause a frostbite hazard. Wear appropriate personal protective clothing to prevent the skin from becoming frozen. |
