a.
NR = Not Required
S = Separation by a partial noncombustible partition
R =
Separate Rooms
1 hr. = 1-hour fire-barrier construction
b.
Hazardous production material gas shall be separated from HPM liquids and solids
by a 1-hour fire-barrier or shall be kept in approved gas cabinets.
c.
Separation by not less than 20 feet is allowed
in lieu of a noncombustible
partition.

Figure 2: Partial List of Incompatible Chemicals
The following list of chemicals in the left-hand column should be transported, stored,
used, and disposed of in such a manner that they do not accidentally come in contact
with the corresponding chemicals in the right
–hand column. These chemicals could
react violently if allowed to come in accidental contact with each other,
resulting in an
explosion, or may produce highly toxic and/or flammable gases or vapors. However, it
should be remembered that this list is not in any way complete, but is to serve only as a
guide for the commonly used chemicals.
Primary Chemical
Incompatible with
Acetic acid
Chromic acid, ethylene glycol,
hydroxyl-containing compounds,
nitric acid, perchloric acid, permanganates and peroxides.
Acetone
Bromine, chlorine, nitric acid, and sulfuric acid.
Acetylene
Bromine, chlorine, copper, mercury, and silver.
Alkaline and alkaline
earth metals such as
calcium, cesium,
lithium, magnesium,
potassium and
sodium.
Carbon dioxide, chlorinated hydrocarbons, and water.
Aluminum and its
alloys (as powders)
Acid or alkaline solutions, ammonium persulfate and water,
chlorates, chlorinated compounds, nitrates, and organic
compounds in nitrate/nitrite salt baths.
Ammonia
(anhydrous)
