(Practice)Standard Practice for Safe Filling of Low-Pressure Pressurized Products
Standard Practice for Safe Filling of Low-Pressure Pressurized Products
ABSTRACT
This practice covers the procedures for filling low-pressure pressurized products in laboratory research and experimental work and in commercial refrigeration and pressure filling. Propellants and chemicals should be properly stored and handled. Care should be taken when handling sealing machinery such as crimpers and seamers and aerosol containers. Safety equipment should be installed and all basic and additional safety precautions should be properly disseminated and observed.
SCOPE
1.1 This practice covers the filling of low-pressure pressurized products, either in the laboratory or in production.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 2.
