Stores ventilated

A vital point in flammable liquids safety is the prevention of the accumulation of explosive concentrations of vapors in closed off areas. Wherever either moderately or highly flammable liquids are used or stored, ventilation is a very important consideration... 

The thermal conductivity of solid engineering materials varies with chemical composition, physical structure, state of the substance, temperature, and moisture content. Because grains are stored, ventilated, and dried in bulk, the bulk density of such products also influences their thermal conductivity. At constant moisture content the thermal conductivity can be expressed as a linear function of the bulk density, pi, ... 

Monitor store regularly. Ensure good store ventilation... 

Care must be taken in handling radon, as with other radioactive materials. The main hazard is from inhalation of the element and its solid daughters which are collected on dust in the air. Good ventilation should be provided where radium, thorium, or actinium is stored to prevent build-up of the element. Radon build-up is a health consideration in uranium mines. Recently radon build-up in homes has been a concern. Many deaths from lung cancer are caused by radon exposure. In the U.S. it is recommended that remedial action be taken if the air in homes exceeds 4 pCi/1. 

The following cautions should be observed Do not destroy or remove inhibitor. Do not contaminate with alkaline or strongly acidic materials. Do not store in the presence of a water layer. In the event of spillage or misuse that cause a release of product vapor to the atmosphere, thoroughly ventilate the area, especially near floor levels where vapors will collect. 

Titanium trifluoride can be stored in tightly closed polyethylene containers for several years. Shipping regulations classify the material as a corrosive sohd and it should be handled in a fully ventilated area or in a chemical hood. The ACGIH adopted toxicity values (1992—1993) for TiF is as TWA for fluorides as F 2.5 mg/m. ... 

Dry oxahc acid is packed and sold in polyethylene-lined, multilayered 25-kg paper bags or in polyethylene-lined 300—600-kg PVC flexible containers. It should be stored in a cool, dry, ventilated place. For storage of its solutions at ordinary temperature, 316 stainless steel is often used as a constmction material. 

Because of the high vapor pressure of the simple quinones and their penetrating odor, adequate ventilation must be provided in areas where these quinones are handled or stored. Quinone vapor can harm the eyes, and a limit of 0.1 ppm of 1,4-benzoquinone in air has been recommended. Quinone in either sohd or solution form can cause severe local damage to the skin and mucous membranes. Swallowing benzoquinones may be fatal the LD q in rat is 130 mg/kg orally and 0.25 mg/kg intravenously. There is insufficient data concerning quinones and cancer. The higher quinones are less of a problem because of their decreased volatihty (118—120). 

Succinic acid and succinic anhydride are sold in 25-kg net polyethylene (PE) bags having cardboard box protection for the anhydride, in 70-liter (50-kg net) fiber dmms, and in 55-gaHon (275-lb 125-kg net) dmms. The two products must be stored in a fresh, dry, ventilated area. Succinic anhydride must be carefully protected from moisture during transportation and storage to avoid hydrolysis to succinic acid. 

The barium crowns are usually broken into smaller pieces and can be sold in this form or cast or extmded into bars or wire. Usually the metal is packaged in argon-fiked plastic bags inside argon-fiked steel containers. Barium is classed as a flammable soHd and cannot be mailed. It should be stored in a wek-ventilated area so as to remove any hydrogen formed through reaction with water vapor. It should not be stored where contact with water is possible. 

Diethyl chlorophosphate, supplied by Aldrich Chemical Company, Inc., was used by the submitters without purification and was handled in a glove bag under an atmosphere of dry nitrogen in a well-ventilated hood. The reagent was distilled and stored under nitrogen by the checkers. Aliquots were withdrawn with a syringe as needed. 

Store in the open air if possible, or at least in a well-ventilated area which is not below ground level. 

Stores should be ventilated and sound, e.g. no cracks in floors, no rusty window frames, no water seepages, etc. 

Stores should be adequately ventilated and, ideally, located outside and protected from the weather. 

Store in the open in a well-ventilated area at ground level. 

Store in a purpose-built compound preferably in the open air and well ventilated.
