Treating a benzene suspension of sodium borohydride (4 equiv.) With glacial acetic acid (3.25 equiv.) And refluxing the mixture for 15 min under nitrogen, after the initial rapid gas evolution subsided (ca. 3 mol of Hz liberated) [No Smoking ], gave a clear solution of NaBH(OAc)3. ...

Minimize stocks and segregate from other chemicals and work areas. Where appropriate, keep samples dilute or damp and avoid formation of large crystals when practicable. Add stabilizers if possible, e.g. to vinyl monomers. Store in specially-designed, well-labelled containers in No Smoking areas, preferably in several small containers rather than one large container. Where relevant, store in dark and under chilled conditions, except where this causes pure material to separate from stabilizer (e.g. acrylic acid). 

Stores and work areas should be designated No Smoking areas and access controlled. Depending upon scale, explosion-proof electrics and static elimination may be required. 

Stores should be specially designed, constructed of non-combustible material, and located away from other hazards (e.g. brick coal bunkers are suitable for small samples, but purpose-built constructions with explosion-proof lights etc. are required for larger quantities). They should be designated No Smoking areas and be well labelled.

Adhesives are not used Just for structural applications on modern aircraft. In fact, the number of non-structural applications of adhesives vastly outnumbers the structural applications. Adhesives are used for everything from assembling lavatory walls to attaching the No Smoking sign to cabin partitions. Just a sampling of adhesive types and applications are discussed below. 

There shall be no smoking or eating in the weighing area. All filters will be handled with tongs or tweezers. Do not handle the filters with bare hands. 

The flow should move smoothly into the cupboard and should not re emerge into the laboratory. It should be remembered that the smoke test is a negative test, i.e., if smoke is seen to emerge from the cupboard, the cupboard does leak if no smoke is seen to emerge, the cupboard may leak. 

Aryloxyphosphazene copolymers can also confer fireproof properties to flammable materials when blended. Dieck [591] have used the copolymers III, and IV containing small amounts of reactive unsaturated groups to prepare blends with compatible organic polymers crosslinkable by the same mechanism which crosslinks the polyphosphazene, e.g. ethylene-propylene and butadiene-acrylonitrile copolymers, poly(vinyl chloride), unsaturated urethane rubber. These blends were used to prepare foams exhibiting excellent fire retardance and producing low smoke levels or no smoke when heated in an open flame. Oxygen index values of 27-56 were obtained.
