Rubber buckets

Fig. 39. Removal of mercury fulminate from the reaction flask to a rubber bucket, according to Budnikov et al. [61].

Upon leaving the filter house, where it has been washed and filtered, and has satisfactorily passed the heat test, it is drawn off from the lowest tank in indiarubber buckets, and poured down the conduit leading to the precipitating house, where it is allowed to stand for a day, or sometimes longer, in order to allow the little water it still contains to rise to the surface. In order to accomplish this, it is sufficient to allow it to stand in covered-in tanks of a conical form, and about 3 or 4 feet high. In many works it is previously filtered through common salt, which of course absorbs the last traces of water. It is then of a pale yellow colour, and should be quite clear, and can be drawn off by means of a tap (of vulcanite), fixed at the bottom of the tanks, into rubber buckets, and is ready for use in the preparation of dynamite, or any of the various forms of gelatine compounds, smokeless powders, c., such as cordite, ballistite, and many others. 

The use of personal vehicles, company or institutional vehicles (including airplanes), and customer vehicles for transporting regulated materials, which may be hazardous, is a serious concern. Most businesses and academic institutions forbid the use of privately owned personal vehicles, due to the serious insurance consequences if an accident occurs. Most individuals will find that their personal vehicle insurance does not cover them when they are transporting hazardous materials. Anyone who needs to transport regulated materials personally between buildings within an institution should walk. (Secondary containment, such as a rubber bucket, should always be used for carrying bottled chemicals.)...

The rubber belt of a bucket elevator, fitted with aluminium buckets and used for transporting solid chlorate, jammed during use. Friction from the rotating drive pulley heated and powdered the jammed belt. A violent explosion consumed all the rubber belt and most of the 90 aluminium buckets. Bronze and steel equipment is now installed. 

Irradiations with this type of light source are carried out using a 1-1. Erlenmeyer flask as the reaction vessel instead of a l.S-1. beaker. The flask is placed in a cold-water bath that is supported on a magnetic stirrer. The bath can be made from a 10-qt. polyethylene bucket with a -in. hole bored about 1 in. from the top of the bucket and a piece of rubber tubing with a -in. bore and i-in. wall inserted as a drain. A stream of 24° tap water run into the bucket at flow rate of 51. per min. maintains the temperature of the reaction mixture below 33°. 

Any NG left after tests or in waste waters should be mixed, by means of a hard rubber spatula, with sawdust in a waste bucket and sent to the burning grounds. All the apparatus which contained NG should be cleaned... 

The following accident was described in a cordite factory. A worker wearing rubber shoes wanted to clean his hands which were soiled with powder dough. He rubbed his hands together and held them towards a bucket filled with acetone standing on the concrete floor. A spark between the hands and the surface of the acetone ignited the latter. 

Wear breathing apparatus, eye protection, laboratory coat, and butyl rubber gloves. Cover spill with 1 1 1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand.8 For each 1 mL of iron pentacarbonyl, place 45-50 mL of household bleach (about 5% sodium hypochlorite solution) in a plastic bucket equipped with a stirrer and located in a fume hood. Dilute the bleach with three times its volume of water and, to this solution, slowly add the contaminated spill mix while stirring. Continue the stirring for a period of 48 hours, and then filter the slurry using vacuum filtration. The... 

Wear eye protection, laboratory coat, and nitrile rubber gloves. Shovel into bucket and add, a little at a time and while stirring, to a large volume of ice water. Neutralize with 5% hydrochloric acid and wash into the drain.16 Spill site should be washed thoroughly with water.14... 

Sodium Metal. Instruct others to maintain a safe distance. Wear face shield, goggles, laboratory coat, and nitrile rubber gloves. Cover sodium with dry sodium carbonate or calcium carbonate, shovel into dry bucket, and transport to fume hood. Behind a shield, add a little at a time to a large excess of dry butanol. Leave to stand for 24 hours and run to waste, diluting greatly with at least 50 times its volume of water.32... 

It is supplied with a dual purpose head. The buckets can either swing out to the horizontal position or, by means of a rubber adapter, the buckets can be held at a fixed angle of 45° (M.S.E.) or 51° (International) in the latter case, the instrument acts as an angle centrifuge. This is an alternative to the hand centrifuge.
