It is the responsibility of all supervisors, trainers, and managers toĮnsure that all employees who work with compressed gases are properly trained In laboratory animals it has an LC 50 not more than 5000ml/m 3. Toxic to humans as to pose a hazard to health and in the absence of adequateĭata on human toxicity, is presumed to be toxic to humans because when tested Less at 14.7psia (101.3 kPa, abs), is known to be so Toxic Gas - Any Material which has a boiling point of 68 oF (20 oC) or Or animals that achieve its intended purpose through chemical rather than The diagnosis, cure, mitigation, treatment, or prevention of diseases in a man Supplements and gas(es) intended for direct use in Gas(es) recognized in the current USP-NF and its NOTE- compressed medical gases include the following: In combination with other gases that is a drug as defined by the Federal Food, Drug, and Cosmetic Act, 21 USC These limits shall be determined in accordance with ASTMĮ681, Standard Test Method for Concentration Limits of Flammability ofĬompressed Medical Gas - Medical liquefied or vaporized gas alone or (101.3 kPa, abs) with air of at least 12% regardless Mixture of 13% or less by volume with air and has flammable range at 14.7psia Ignitable at 14.7psia (101.3 kPa, abs) when in a (20 oC) or less at 14.7psia (101.3 kPa, abs) which is University of Rochester include oxygen and nitrogen.įlammable Gas - Any material which has a boiling point of 68 oF Having a vapor pressure exceeding 40 psi at 100 oF (37.8 oC) as determined by ASTMĬryogenic Liquid - A cryogenic liquid is any liquid with a boiling (54.4 oC), or both, regardless of the pressure at 70 oF (21.1 oC) or, a liquid (21.1 oC), or an absolute pressure exceeding 104 pounds per square inch at 130 oF The ambient atmosphere, and can thus cause oxygen deprivation in those who areĮxposed, leading to unconsciousness and death.Ĭompressed Gas - Any material or mixture having in a containerĮither an absolute pressure exceeding 40 pounds per square inch at 70 oF Please note that ALL Laboratory Safety Training courses contain both compressed gas and cryogenicĪsphyxiant Gas - A gas or mixture of gases that displaces oxygen in Training courses for compressed gases depending on the type of work with compressed gases. ![]() The online training courses can be found through the University of Rochester’s MyPath website. Training must be completed BEFORE an employee is allowed to handle compressed gases. Practical training, as overseen by their supervisor. ![]() A competent user is defined as someone who is authorized to useĬompressed gases after completing a University of Rochester sanctioned in person or online training course and test that is knowledge based, as well as This policy establishes requirements for all competent personnel to safely handle and use compressed gas cylinders. The appropriate documentation for cryogenics can be found at. This document does not cover cryogenic cylinders. Properly utilized, transported, and stored.Īdditional information is available by contacting Environmental Health & Safety. Operating procedures when using gas cylinders to ensure the cylinders are Therefore, personnel must follow all established Uncontrolled release can create a hazardous situation in the area in a very Because gas cylinder contents are under high pressure, any Pyrophoric, oxidative, an asphyxiant, and/or may present a combination of these The gas may be classified as flammable, toxic, corrosive, The gas contents in a cylinder can present physical and/or health All employees mustĪlso abide by all local, state, and federal laws. To follow these requirements may result in injury or death. It is a requirement that all University of Rochester employees who handleĬompressed gases understand the health and safety hazards of the compressed gasĬylinders, including proper handling, use, storage, and emergency procedures.
