Leather gloves

Potassium forms corrosive potassium hydroxide and Hberates explosive hydrogen gas upon reaction with water and moisture. Airborne potassium dusts or potassium combustion products attack mucous membranes and skin causing bums and skin cauterization. Inhalation and skin contact must be avoided. Safety goggles, full face shields, respirators, leather gloves, fire-resistant clothing, and a leather apron are considered minimum safety equipment. 

Wear proteetive elothing appropriate to the work, e.g. leather gloves, fire-retardant overalls, safety shoes or boots and eye proteetion. 

Caution. The reaction is exothermic and n-butane gas is produced. Therefore, sufficient cooling and a slow addition of the n-BuLi/hexanes solution are required. n-BuLi can ignite on contact with water or air. During the addition of n-BuLi solutions the storage bottle should be kept in the metal container provided by the supplier, and leather gloves should be worn because disposable gloves react immediately with n-BuLi. 

The liquid sulfur dioxide solutions described in the preparations have a vapor pressure of about 3.3 atm at 21 °C. Therefore, well-constructed glass vessels and a glass (or metal) vacuum line must be employed to prevent pressure bursts. Thick leather gloves, safety goggles, a face shield, and a rubber apron should be worn and the experiments have to be conducted behind a safety shield or explosion-proof glass in a fume hood to prevent possible contact with the reaction mixtures as well as with AsF5 and SbFs. 

Little other individual protective equipment emerged during the First World War beyond impregnated leather gloves and linseed oil-impregnated suits for occasional use by troops in areas where mustard gas had been employed. These items were not in general use however, and the war ended before the particular problems associated with the protection of the skin against mustard gas had been studied. The only other notable... 

Wear leather gloves, eye protection, and laboratory coat. Work from behind body shield. Avoid unnecessary heat, friction, or impact. Absorb the liquid on paper towel. Place paper towel in a beaker containing concentrated hydrochloric acid (about 100 mL of acid for each 1 g of azide). Follow waste disposal procedure. Wash spill site thoroughly with soap and water.7,8... 

Wear leather gloves, heavy face shield, and laboratory coat. Work from behind a body shield. Avoid unnecessary heat, friction, or impact. 

Wear leather gloves, a heavy face shield, goggles, and a laboratory coat. Cover the spill with a 1 1 1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. With a plastic scoop, shovel the mixture into a plastic container and transport to the fume hood. Very slowly, add the mixture to a large beaker containing concentrated hydrochloric acid (100 mL/g azide) and granular tin (6 g/g azide). Stir for 30 minutes, and then cautiously add the solution to a pail of cold water. The solid may be treated as normal refuse. Neutralize the aqueous solution with sodium carbonate and wash into the drain.5... 

Caution Carry out all procedures in a well-ventilated hood, and wear disposable vinyl or latex gloves and chemical-resistant safety goggles. For handling diethyl-zinc wear a long laboratory coat, leather gloves, and a helmet with a face protection shield.
