Section 4. First aid measures
No action shall be taken involving any personal risk or without suitable training.If fumes are still suspected to be present,
the rescuer should wear an appropriate mask or a self-contained breathing apparatus.It may be dangerous to the person
providing aid to give mouth-to-mouth resuscitation.
: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.
Eye contact
DO NOT remove contact lenses, if worn. Obtain medical attention without delay,
preferably from an ophthalmologist.
: Immediately warm frostbite area with warm water (not to exceed 40.5 C, 105F).
Skin contact
Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly
clean shoes before reuse. Get medical attention.
: Try to warm up the frozen tissues and seek medical attention.
Frostbite
: If inhaled, remove to fresh air. If breathing is difficult, give oxygen. If not breathing, give
Inhalation
artificial respiration. Get medical attention.
: Do NOT induce vomiting unless directed to do so by medical personnel. Never give
Ingestion
anything by mouth to an unconscious person. Get medical attention if symptoms
appear.

: Do not extinguish due to possible hazard of explosive reignition. Use water to cool
Fire fighting media and
containers and structures and to protect personnel attempting to shut-off flow. Attempt
instructions
shut-off only if hazard is not too great. Extinguish surrounding and/or residual fires with
appropriate fire fighting foam, carbon dioxide or dry chemical media.
If involved in fire, shut off flow immediately if it can be done without risk. Apply water
from a safe distance to cool container and protect surrounding area.

sparks and flame. To avoid fire, minimize ignition sources. Use explosion-proof
electrical (ventilating, lighting and material handling) equipment. Do not puncture or
incinerate container. High pressure gas. Use equipment rated for cylinder pressure.
Close valve after each use and when empty. Protect cylinders from physical damage; do
not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement.
: Keep container tightly closed. Keep container in a cool, well-ventilated area. Cylinders
Storage
should be stored upright, with valve protection cap in place, and firmly secured to
prevent falling or being knocked over. Cylinder temperatures should not exceed 52 掳C
(125 掳F).
Section 8. Exposure Controls, Personal Protection
: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation, or
Engineering controls
other engineering controls to keep airborne levels below recommended exposure limits.
The engineering controls also need to keep gas, vapor or dust concentrations below any
explosive limits. Use explosion-proof ventilation equipment.

Gas Density (lb/ft3) : Weighted average: 0.11
Section 10. Stability and reactivity
: The product is stable.
Stability and reactivity
Conditions to avoid: Stable as mixed; however, contains unstable materials
(methylacetylene and propadiene). Weathering off (evaporation of light components)
may allow concentration of the methylacetylene and propadiene to reach concentrations
which would make mixture unstable on heating. Avoid heating of mixture or venting of
lights that could cause lighter materials to weather off(evaporate).
Incompatibility with various : Extremely reactive or incompatible with oxidizing agents.
Reactive with metals.
substances
|Additionally, avoid contact with acetylide-forming metals (copper,silver and mercury).
Copper alloys (such as brass) containing sixty six percent (66%) or more of copper
should not be exposed to MAPD.
Hazardous polymerization : May Occur.
Conditions to Avoid: Elevated tempertures and pressures. Polymerization catalysts,
such as metal alkyls, can cause uncontrolled polymerization. Contamination with oxygen
can cause propadiene to form hazardous peroxides.
INHIBITORS/STABILIZERS
An ihibitor is added to the MAPD mixture to prevent potential unstable peroxide
formation. Butanes (iso and/or normal) are also added to the MAPD mixture to prevent
potential concentration of the methylacetylene and propadiene from reaching
concentration levels that would render the mixture unstable in case of weathering off
(evaporation of light components).
