  • Compressed Gases & Cryogens
    COMPRESSED GASES & CRYOGENS Compressed gas cylinders and cryogen Dewars must be handled with caution at all times. Assume all cylinders contain gas under pressure and treat all gases as hazardous chemicals. When using gas or cryogens, make sure to wear closed-toe shoes and safety glasses as a minimum, and tailor personal protective equipment to each hazard. HAZARDS OF COMPRESSED GASES Physical and health hazards are present with use of compressed gases. • The high pressure in cylinders (4.4 to 6,000 psig) makes the gas cylinder a potential physical explosive rocket that could punch through walls. • Some gases may be corrosive which could result in change in tissue and/or equipment at the point of contact. • Cryogenic gases have dangers of low temperature, potential frostbite, and they may expand into large volumes of gas that could displace oxygen and result in suffocation. • Inert gases and oxidizing reactions may create oxygen deficiency hazards by displacing oxygen and may lead to suffocation. The early symptoms may be dizziness and weakness, which may lead to unconsciousness and death. This is also termed asphyxiation. • Flammability is a concern especially with the gases acetylene, hydrogen, and propane. • The permissible exposure limits for toxic materials is very low and so even small exposure is considered to be poisonous. • Oxygen leaks may create oxygen enriched atmospheres which increase the risk of fire and explosions. Watch a video demonstrating the hazard at http://youtu.be/ZNiZaVT1mBY. • See additional hazards listed on safety data sheet for each chemical. Compressed gas cylinders must be handled with caution at all times.

  • Compressed Gas Cylinder Safety
    COMPRESSED GAS CYLINDER SAFETY Compressed gas cylinders are a common fixture in research laboratories. As such it is imperative to understand safe handling, transportation and use of compressed gas cylinders. A compressed gas is defined by the Occupational Health and Safety Administration (OSHA) per 29 CFR 1910.1200 as: A gas or mixture of gases having, in a container, an absolute pressure exceeding 40 psi at 70 deg. F (21.1 deg. C); or a gas or mixture of gases having, in a container, an absolute pressure exceeding 104 psi at 130 deg. F (54.4 deg. C) regardless of the pressure at 70 deg. F (21.1 deg. C); or a liquid having a vapor pressure exceeding 40 psi at 100 deg. F (37.8 deg. C) as determined by ASTM D-323-72. The broad definition provided by OSHA makes it difficult to cover all prudent practices concerning compressed gas safety. Therefore, the scope of this document will address compressed gas cylinders that are common in a laboratory environment. SAFE HANDLING AND USAGE Most compressed gas cylinders, whether they are ultra-high purity or industrial grade, will be pressurized to around 2000 psi. This represents an enormous amount of potential energy. If the gas is released uncontrollably or over-pressurizes equipment, there is an immediate hazard to life and health. Furthermore, many compressed gas cylinders will contain flammable or toxic gas. Finally, the threat of asphyxiation due to oxygen displacement by release of compressed gas must also be considered. Always review manufacturers Safety Data Sheet (SDS) before using compressed gas for specific personal protective equipment, usage, and storage guidelines.

These requirements are established to ensure faculty, staff and students know the physical characteristics of the material used and the protective measures necessary to prevent fire, explosion, or violent reaction. 1. Definitions 1.1. Compressed Gas: Any material or mixture having, when in its container, an absolute pressure exceeding 40 psi (an absolute pressure of 276 kPa) at 70°F (21.1°C) or, regardless of the pressure at 70°F (21.1°C), having an absolute pressure exceeding 104 psi (an absolute pressure of 717 kPa) at 130°F (54.4°C). 1.2. Flammable Gas: A material that is a gas at 68°F (20°C) or less at an absolute pressure of 14.7 psi (101.325 kPa), that is ignitable at an absolute pressure of 14.7 psi (101.325 kPa) when in a mixture of 13 percent or less by volume with air, or that has a flammable range at an absolute pressure of 14.7 psi (101.325 kPa) with air of at least 12 percent, regardless of the lower limit. 1.3. Liquefied Petroleum Gas (LP-Gas): Any material having a vapor pressure not exceeding that allowed for commercial propane that is composed predominantly of the following hydrocarbons, either by themselves or as mixtures: propane, propylene, butane (normal butane or isobutane), and butylenes.

Inhalation or skin contact overexposures can be harmful or fatal. This gas mixture can be irritating to the eyes. Hydrogen Cyanide can undergo polymerization. Emergency responders must wear adequate personal protective equipment during response situations. A cylinder rupture hazard exists when this gas mixture, which is under pressure, is subject to heat or flames.
