Mainly acetylene and other hydrocarbons, acetylene most dangerous, very low solubility in liquid oxygen (5.6 × 10-6mg / L), it is easy to solid precipitate and cause an explosion.
Mainly carbon dioxide, water and nitrous oxide, especially nitrous oxide, increasing cause for concern, after their crystallization, blocked the main cold aisle, it will cause the main cold "dry evaporation" and "dead-end boiling", resulting in concentrated hydrocarbons , accumulation, precipitation, causing the main cold explosion.
Chlorine is a strong oxidant
a. solid impurity particles mechanical impact detonation (such as acetylene particle friction, oxygen shock).
b. When static electricity, such as carbon dioxide particles reached (200 ~ 300) × 104ppm, can generate static electricity, voltage up to 3kV.
c. chemical sensitivity exceptionally strong material (such as ozone and nitrogen oxides).
d. flow shocks, pressure shocks, pressure pulses caused by cavitation, causing the temperature rise caused by the explosion.
