Containment, of hazardous

Small lab-pack containers of hazardous waste if they are first placed in nonlealdug, larger containers. These containers must be Filled to capacity and surrounded by enough absorbent material to contain the liquid contents of the lab pack. The resultant container must then be placed in a larger container packed with absorbent material which will not react with, become decomposed by, or ignited by the contents of the inside containers. Incompatible wastes may not be packed and disposed of together in this manner. 

The most common scenario of interest for LOPA in the chemical process industry is loss of containment of hazardous material. This can occur through a variety of incidents, such as a leak from a vessel, a ruptured pipeline, a gasket failure, or release from a relief valve. 

Safeguards against Toxicity Hazards Certainly the best protection against toxicity hazards is complete containment of hazardous materials within processing equipment. 

Disposal Drum A specially constructed drum used to overpack damaged or leaking containers of hazardous materials for shipment. 

Labpack Generally refers to any small containers of hazardous waste in an overpacked drum, but not restricted to laboratory wastes. 

Disposal in Landfills of Small Containers of Hazardous Waste in Overpacked Drums Yes 40 CFR 264.316 EPA 1982e... 

Geomembranes are giant impermeable membranes made of (un)reinforced polymeric materials and used to stabilize earth and to secure landfills ensuring containment of hazardous or municipal wastes and their leachates. Functionalities are varied ... 

Today, almost everyone works or lives with chemicals and chemical prodncts. Over the centuries man has lived in a chemical age, but especially so during the past several decades. Many of the chemical substances can have deleterious effects on animals, humans, and the environment. These substances are capable of causing physical hazards (e.g., lire or explosion) or health hazards (such as systemic toxicity and chemical bums). Improper use of chemical substances causes a wide range of health hazards. It is the responsibility of the user to evaluate each chemical substance and know its potential to cause adverse health effects and pose physical hazards, such as flammability in the workplace. The manufacturers, importers, and distributors of different chemical substances must be sure that containers of hazardous chemicals leaving the workplace are properly labeled with the identity of the chemical and appropriate hazard warnings. In the workplace, each container must be marked with the identity of hazardous chemicals contained in it and must show hazard warnings appropriate for employee protection. 

All containers of hazardous chemicals should be labeled in accordance with OSHA hazard communication standards. Each container of and/or apparatus with hazardous chemical contents in the lab should be labeled with the following information ... 

The benefits to process safety are obvious since eliminating equipment failures removes potential causes for losing control of the process, losing containment of hazardous materials, and the necessity for nonroutine operations. Successfully implementing reliability programs depends upon collecting the proper data to assess performance and maintain reliable, dependable practices. Superior... 

BSC The BSC should operate continuously to ensure containment of hazardous substances. All work-zone interior surfaces with the exception of the HEPA filter-protective screen should be cleaned and sanitized carefully in the manner of the LFCB in the proper order to ensure protection of operator s garb from contaminants and cleaning residues during the cleaning process. This sequence will also prevent the transfer of drug residues to the general environment. " ... 

III BSC is used where absolute containment of hazardous agents is required, and is normally configured with glove ports housing gas-tight, full length latex, neoprene, PVC, urethane, or laminated polymer glovesJ ... 

Premises 3 and 4 (above) imply that the design or operating modifications of a process leading to the elimination or containment of hazards (identified by the inductive approach) can be generated deductively from the knowledge of the plant and its operating conditions. 

Waste materials can be segregated, leading to containment of hazardous and toxic waste, which in turn can improve workers health and safety. 

Jet grouting ean also be used to create horizontal barriers, as also shown in Figure 9.4. This application is important in the containment of hazardous wastes. 

Marking means applying the descriptive name, instructions, cautions, weight or specification marks or combination thereof required by the regulations to be placed upon outside containers of hazardous materials. 

The standard requires that the employer ensure that each container of hazardous chemicals in the workplace is labeled, tagged or marked with the identity of the hazardous chemical(s) and the hazard warnings. 

Label means any written, printed, or graphic material displayed on or affixed to containers of hazardous chemicals. 

The employer shall not remove or deface existing labels on incoming containers of hazardous chemicals, unless the container is immediately marked with the required information. 

Chemical manufacturers and importers shall label containers of hazardous chemicals leaving their workplaces, and provide material safety data sheets with initial shipments by November 25, 1986. 

Labeling a descriptive name, identification number, instructions, cautions, etc. to be placed directly on the primary container of hazardous materials. 

Employers must ensure that each container of hazardous chemical in their workplace is labeled, tagged, or marked to identify the chemical and its specific hazards. Hazard warning labels must remain on the container even when empty until the container has been cleaned and purged. There are exceptions to the labeling requirements just discussed. For instance, labels are not required for ... 

Labels on containers of hazardous chemicals provide immediate information about the contents of the container and the hazards associated with the contents. Labels are important for use in determining handling methods and immediate emergency response action. All containers of hazardous chemicals must be appropriately labeled to show the hazards of the contents and other necessary information. The two most common labels are the NFPA and HMIS labels. 

There are two important types of labels in laboratories. The labels on commercial containers are usually extremely comprehensive, providing not only information on the nature, amount, and quality of the product but also a very laige amount of safety-related data. Typically a commercial label will readily meet the requirements of the hazard communication standard. On the other hand, labels placed on secondary containers in the laboratory by employees may be something such as soln. A or even less. This may be sufficient if all of the material is to be promptly used by the individual placing the label on the container, but otherwise it is not. In most instances, secondary containers of hazardous chemicals should be marked with labels identifying the chemical in the container and providing basic hazard warnings. The secondary label should be affixed before the container is put into use.
