Ventilation storage areas

One of the daughter products of natural radiation is radon gas. In order to allow this gas to dissipate, it is important to ventilate storage areas and/or... 

Store chemical substances according to their primary hazard classification. Store chemical substances in a cool, dry, properly ventilated storage area away from direct sunlight. 

Store volatile chemical substances in a well ventilated storage area. 

Cloth, especially cotton, and diatomaceous earth filters can also be responsible for transmitting off-flavors they may have picked up in damp, poorly ventilated storage areas. 

Can ignite spontaneously and explosively In air at fast flow rates from cylinder or in the event of gas leak. High atmospheric concentrations, e.g. in poorly ventilated epecee, can cause oxygen deficiency, with risk of unconsciousness. Use special hydrogen detector. Ventilate storage area at highest level. 

The areas for the reactors and storage tanks should be separated by fire walls, and must be adequately ventilated. Storage tanks should be blanketed by inert gas. A slight positive pressure of inert gas should be maintained in the reactor or storage tanks during the discharging of the resin or resin solution to prevent air from being sucked into the vessel to form an explosive mixture with the solvent vapor. 

They would require a larger storage area, which should be dustproof but well ventilated to provide for sufficient air circulation. 

Appropriate gas/vapour/fume/pressure venting, e.g. flame arrestors, scrubbers, absorbers, stacks Ensure adequate natural or forced general ventilation of the storage area Provide adequate, safe lighting... 

The entire space within the building or storage area and outside any doorway, low level ventilator or other opening into the store within the separation distance set out in Table 9.1 7, column 3, up to a height of 1.5 m above ground level. 

The satellite buildings contain service areas, laboratories, storage areas, offices, and various utilities (ventilation, electricity, brine, steam, inert gas and water for fire protection). 

The heating, ventilation, and air conditioning (HVAC) system is designed to create airflow, which has a cascading effect. It provides a pressure differential between the aseptic filling suites (critical/controlled access areas, class 100 level I and level II and the sterile storage unit of at least 15 Pa. In addition, a pressure differential is maintained between the sterile storage area (controlled access area, class 100, level II) and the controlled areas (class 10,000 and class 100,000) of at least 20 Pa at all times. 

Work with 10% buffered neutral formalin is recommended to be executed in a well-ventilated area, wearing goggles, gloves, and lab coat. Storage areas should have appropriate ventilation systems. 

Where flammable solvents and adhesives are used, they must be stored, handled, and used in a manner preventing any possibility of ignition. Proper safety containers, storage areas, and well-ventilated workplaces are required. 

Ventilation switches and emergency protection equipment should be located outside the storage area in easily accessible locations, which would be uncontaminated in the event of an emergency. 

However, low temperature (5-10°C) and a relative humidity of 95% or higher are recommended if an extended storage period after irradiation is anticipated. For irradiated onions, storage at low temperature is recommended, but high relative humidity was found to contribute to rotting. For both irradiated potatoes and onions, good ventilation in the storage area is also necessary. 

Powered ventilation systems in chemical warehouses are typically used for some flammable gas and liquid storage areas (see Gas and Vapor Control, Section 6.6). Heating and ventilation systems and powered roof exhaust systems can be arranged to shut down automatically upon receipt of a fire alarm signal so as not to interfere with sprinkler system operations due to airflow. Furthermore, these systems can also be arranged for manual starting and full exhaust by the fire department for smoke removal during search and rescue operations.
