GHS labeling requirements are not required for chemicals being stored in a laboratory. However, since most chemicals stored in the laboratory have been purchased from a chemical manufacturer, the GHS labeling and pictogram requirements are very relevant and must be understood by laboratory employees. Figure 2.3 illustrates the GHS label format showing the required elements. ACETONE PRODUCT IDENTIFIER Code: HAZARD PICTOGRAMS
Compressed Gas Cylinder Safety Compressed gas storage requirements are discussed above in Section 5.7.3. However, there are additional important safety requirements for use of compressed gases in laboratories detailed below: Gas cylinder connections and fittings must be inspected frequently for deterioration. Never use a leaking, corroded, or damaged cylinder and never refill compressed gas cylinders. When stopping a leak between cylinder and regulator, always close the valve before tightening the union nut. The regulator must be replaced with a safety cap when the cylinder is not in use. The safety cap must be in place when a gas cylinder is moved. For large gas cylinders (>27 inches), an approved gas cylinder cart should be used. The cylinder must be strapped to the cart and the protective cap must be in place before moving the cylinder. A cylinder should never be moved or transported without the protective cap. The proper way to move a large gas cylinder is illustrated in Figure 5.7. Never dispense from a cylinder if it is on a gas cylinder cart. Figure 5.7 – Gas Cylinder Cart A few compressed gas cylinders have a shelf-life and can become more hazardous as time goes on. It is extremely important that these chemicals are identified and managed properly. If any time-sensitive gases are found to be past the manufacturer’s expiration date, they must be submitted to REM for hazardous waste disposal immediately. The following is a list of compressed gases: Hydrogen Fluoride, anhydrous Hydrogen Bromide, anhydrous Hydrogen Sulfide, anhydrous Hydrogen Cyanide, anhydrous Hydrogen Chloride, anhydrous The compressed gases listed above have a shelf-life provided by the manufacturer that must be strictly followed. There have been numerous incidents involving these compounds related to storage past the expiration date. For example, hydrogen fluoride (HF) and hydrogen bromide sensitive

Flash Point: The minimum temperature at which vapors are formed on the surface of a substance in sufficient quantity to ignite when exposed to an ignition source. Boiling Point: The temperature at which the vapor pressure of a liquid equals the atmospheric pressure and the liquid changes into a vapor.
