Protective personnel

A filter cake from the wringer is washed to remove absorbed acid, transferred to a slurry tank of water, and quickly submerged, after which the nitrocellulose is pumped to the stabilization operation as a diluted water slurry. Exhaust systems are installed to protect personnel and equipment from acid fumes, and water sprays and cyclone separators are used for acid fume recovery before venting to the air. 

The furnace is constmcted with a steel shell lined with high temperature refractory (see Refractories). Refractory type and thickness are deterrnined by the particular need. Where combustion products include corrosive gases such as sulfur dioxide or hydrogen chloride, furnace shell temperatures are maintained above about 150—180°C to prevent condensation and corrosion on the inside carbon steel surfaces. Where corrosive gases are not present, insulation is sized to maintain a shell temperature below 60°C to protect personnel. 

The manufacturing cost consists of direct, indirect, distribution, and fixed costs. Direct costs are raw materials, operating labor, production supervision, utihties, suppHes, repair, and maintenance. Typical indirect costs include payroll overhead, quaHty control, storage, royalties, and plant overhead, eg, safety, protection, personnel, services, yard, waste, environmental control, and other plant categories. However, environmental control costs are frequendy set up as a separate account and calculated direcdy. The principal distribution costs are packaging and shipping. Fixed costs, which are insensitive to production level, include depreciation, property taxes, rents, insurance, and, in some cases, interest expense. 

Insulation provides other functions in addition to energy conservation. A key role for insulation is safety. It protects personnel from bums and minimizes hot surfaces that could ignite inflammables. It also protects equipment, piping, and contents in event of fire. Thus materials such as mineral wool are sometimes used despite relatively poor thermal quaUties. 

Has an effective safety and health program (for example, safety procedures, training, hazard identification and analysis) been established to protect personnel on the work site, including employees and contractors If no, explain. 

Provision of efficient drift eliminators of water cooling towers consideration of replacement by air cooling systems. Thermal insulation to protect personnel from contact with hot or cold surfaces prevention of water supply disruption by freezing. 

The CDC-NIH document describes, in detail, the different uses of the different classes and types of BSCs and the type of protection (personnel, product, and environmental) each type provides. The document also provides a detailed comparison of filtration (air cleaning), airflow pattern (into the cabinet from the room or from the supply duct), and necessary performance tests (leak, velocity profile, differential pressure, etc.) for each type of BSC (see also Simons ). 

Noise can constitute a danger to health, and therefore adequate precautions must be taken to protect personnel who are required to be in such an environment. The Health and Safety at Work, etc. Act 1974 has the power to control noise emissions, but the subject is complex. If it is anticipated that noise will exceed acceptable levels then... 

Vaporizing liquid halogen agents are electrically non-conductive and are effective on a wide range of combustibles, particularly flammable liquids and electrical fires. A lock-off system is required on fixed installations to protect personnel, the normal extinguishing concentration being 5% by volume. 

Down-Draft Hood. To protect personnel from benzene vapors, it is recommended that all the pouring, container closing, and final decantation and bottling operations be performed on an efficient down-draft hood (4) To increase efficiency in inserting and removing the bolts on the steel cans, a reversible air-driven screwdriver has been suspended on a counterweight over the down-draft hood. 

Whenever the operation to be performed involves the potential to cause the initiation of the propellant, explosive or pyrotechnic (PEP) component(s) of a munition item, the APE is either operated by remote control, with the operator behind a protection wall or barrier, or it is enclosed in a protective barricade or operational shield. Barricades or operational shields are designed to protect personnel and assets from the effects of blast overpressures, thermal effects or fireball, and fragments result from the initiation of PEP components, such as the fuze, primer, propelling charge, burster, etc. 

An Emergency Shutdown (ESD) system is a method to rapidly cease the operation of the process and isolate it from incoming or going connections or flows to reduce the likelihood of an unwanted event from occurring, continuing, or escalating. The aim of an ESD system is to protect personnel, afford protection to the facility, and prevention of an environmental impact from a process event. 

Facility personnel who perform inspections on fixed fire protection systems must be knowledgeable of the systems and have received training on the inspection protocols. Facility personnel may be operations personnel, maintenance personnel, security personnel, fire protection personnel, or others assigned by management. 

NOTE It is important to verify if drawings require approval by company fire protection personnel regulatory agencies or other authority having jurisdiction (AHJ). Drawing approval may have to be completed by a licensed professional engineer certified in fire protection engineering. 

Facility personnel who perform testing and maintenance on fire protection equipment and systems must be experienced and knowledgeable in the systems and on the protocols for testing and maintenance. Knowledge can include work history, educational experience, craft certification, manufacturer certification, field verification, and job assessment and testing. Testing and maintenance personnel may be pump mechanics, pipe fitters, instrument technicians, electrical technicians, millwrights, fire protection personnel or other qualified personnel. 

Regular safety and routine physical security activities will continue to protect personnel, facilities, and materiel from pilferage, unauthorized use, sabotage, and violation of community rules and regulations by any source, internal or external (U.S. Army, 1995, 2000f). Conceivably, the island could be the target of unauthorized entry and trespassing from the air or sea. Thus, a security presence appears to be warranted until final ownership of the island is established. 

Proper care must be exercised at all times to protect personnel from accidents, fires, or explosions, and to limit damage to equipment and loading areas. In this connection, the precautionary measures in the following paragraphs should be observed...
