Protective controls

Flevated or Remote Air Intakes Elevated or remote air intakes for control rooms will help in reducing ingress of dense, flammable vapors into those rooms. Ordinarily, elevating the tip of the air intake duct 9 m (30 ft) above the ground is sufficient. Installing flammable vapor detectors in the air intake ducts provides additional protection. Controls that automatically stop air to control rooms if vapor concentrations reach 25 percent of their LFL should also be considered. [Pg.2321]

As noted by Roy (4), the world of the university generally presents a rather unimaginative picture. Reasons should be obvious. "Disciplines" are part of a continuum. In fact, separation is sometimes difficult. Portions of chemical and civil engineering, both addressing health-protective control techno-... [Pg.207]

Many large companies are becoming increasingly selective in purchasing chemicals from small suppliers who do not follow sound environmental or worker protection control procedures. This attitude is directly related to the problems associated with the production of kepone by Life Sciences, Inc., for use by a single customer, Allied Chemical Company. Similarly, on a number of recent occasions large chemical companies have withheld sales to... [Pg.184]

In many countries the freedom of the individual investigators to decide the details of their research programme is well protected. Control of day-by-day activities is inappropriate. Nevertheless, in cases such as the above, a preferable procedure would be for two or three selected laboratories to attempt confirmation of the claim. They would then communicate the results to others. Again this massive duplication may be regarded as a corollary of the large number of well-staffed and well-supported research laboratories around the globe. [Pg.131]

Obviously, very stable and long life embeddable reference electrodes are a must for this type of application (long-term corrosion monitoring). However, for cathodic protection control applications the stability requirement is not that important. It is surely desirable for the reference electrode to have a long embedded life . More reports on held experiences with embeddable reference electrodes for concrete would be highly appreciated. [Pg.36]

Visibly clean is not an acceptable cleaning criterion. A detailed, sequential cleaning procedure is advisable, for surfaces inside and outside laboratory chemical hoods and ventilated weighing enclosures. If settling of powder occurs on the floor, this indicates that material is escaping and that additional administrative and personal protective controls are warranted when using chemical fume hoods for subdivision applications. [Pg.400]
