4. Runaway Reaction: An uncontrolled reaction that proceeds at an increasing
rate.
5. Polymerization: A chemical reaction that produces the bonding of two or more
monomers.
6. Overpressurization: Instantaneous energy release or detonation.
7. Corrosion: The presence of the regulated substance could lead to destruction of
equipment and a release. Corrosion may be a major hazard for substances
identified as corrosives on MSDSs unless the equipment used limits the hazard.
8. Overfilling: Filling a tank or vessel beyond its maximum safe capacity.
9. Contamination: A release could occur if inappropriate substances are
introduced into storage or process vessels. Contamination may be a major
hazard if controlling inappropriate substances (e.g., H O) is difficult. 2
10. Equipment Failure: Equipment failure is likely to be a major hazard for most
processes because such failure could lead to a release. Equipment failure
includes cracks, weld failures, disk failures, ruptures, pump/gauge/control
system failures, etc.
11. Loss of Cooling, Heating, Electricity, Instrument Air: These losses could be
major hazards if they would lead to releases. For example, loss of cooling could
lead to an increase in pressure and failure of a vessel or pipe; a loss of heating or
power could lead to unstable processes. These conditions are less likely to be
major hazards for substances handles at atmospheric temperatures and pressures.
12. Earthquake: Report these only if they are frequent enough or likely enough to
occur at your site so that you design and plan for them.
13. Floods (Flood Plain): Report these only if they are frequent enough or likely
enough to occur at your site so that you design and plan for them.
14. Tornado: Report these only if they are frequent enough or likely enough to
occur at your site so that you design and plan for them.
15. Hurricanes: Report these only if they are frequent enough or likely enough to
occur at your site so that you design and plan for them.
16. Other (specify)
e. Process controls: Indicate all of the process controls used on this Program 3 process.
Process controls are equipment and associated procedures used to prevent or limit
releases. Check all that apply.
