The worst industrial accident in the world took place at
Bhopal
The Bhopal, India, incident is best described by the following statement:
Bhopal gas tragedy, was a gas leak incident on the night of 2-3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. It is considered to be the world's worst industrial disaster. Over 500,000 people were exposed to methyl isocyanate (MIC) gas. The highly toxic substance made its way into and around the small towns located near the plant.

back away
Liquid fires depend on a ___________ mixture above the product
gas and air mixture
Solid and liquid fires must burn in the _______ phase.
gas phase
The effects of absorbed heat include all of the following except:
increase in volume, temperature, change of state, chemical change and electrical transfer
Denotations are a special type of explosion that are extremely destructive because they
it travels at high velocity and produce high internal pressures.
