Process Safety Management of Highly Hazardous Chemicals is a regulation promulgated by the U.S. Occupational Safety and Health Administration (OSHA). [1] It defines and regulates a process safety management (PSM) program for plants using, storing, manufacturing, handling or carrying out on-site movement of hazardous materials above defined amount thresholds.
Section 8 permits OSHA inspectors to enter, inspect and investigate, during regular working hours, any workplace covered by the Act. [25] Employers must also communicate with employees about hazards in the workplace. By regulation, OSHA requires that employers keep a record of every non-consumer chemical product used in the workplace.
Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (7.9 in). Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm. Cut-off grinders are useless for these kinds of application. Robotic oxy-fuel cutters sometimes use a high-speed divergent nozzle.
Methods of oxygen storage for subsequent use span many approaches, including high pressures in oxygen tanks, cryogenics, oxygen-rich compounds and reaction mixtures, and chemical compounds that reversibly release oxygen upon heating or pressure change. O 2 is the second most important industrial gas.
The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).
A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
The Occupational Safety and Health Act grants OSHA the authority to issue workplace health and safety regulations. These regulations include limits on hazardous chemical exposure, employee access to hazard information, requirements for the use of personal protective equipment, and requirements to prevent falls and hazards from operating ...
The flashback arrestors are suitable for most technical gases (fuel gases) such as acetylene, hydrogen, methane, propane, propylene and butane as well as oxygen and compressed air. Flashback arrestors have to be tested for gas non-return, for tightness and for gas flow by a qualified person depending on the country specific regulations.
