Procedures safety

During the modeling practices of the plant lifecycle, procedures are defined as the steps within each operation and as set of constraints associated with the different model elements of the plant lifecycle model. This will facilitate the automatic generation of the related safety procedures associated with the target process within the plant. This has been represented to operator in the form of HTME pages.

Hydrogen chloride in air can also be a phytotoxicant (88). Tomatoes, sugar beets, and fmit trees of the Pmnus family are sensitive to HCl in air. Exposure of concentrated hydrochloric acid to the skin can cause chemical bums or dermatitis. Whereas the irritation is noticed readily, the acid can be water flushed from the exposed area. Copious use of miming water is the only recommended safety procedure for any external exposure. Ingestion is seldom a problem because hydrochloric acid is a normal constituent of the stomach juices. If significant quantities are accidentally swallowed, it can be neutrali2ed by antacids. 

Sta.rting from Phenol. Phenol can be selectively oxidized into -benzoquinone with oxygen. The reaction is catalyzed by cuprous chloride. At low catalyst concentration, the principal drawback of this method is the high pressure of oxygen that is required, leading to difficult safety procedures. It appears that a high concentration of the catalyst (50% of Cu(I)—phenol) allows the reaction to proceed at atmospheric pressure (58). 

Nonmolecular species, including radiant quanta, electrons, holes, and phonons, may interact with the molecular environment. In some cases, the electronic environment (3), in a film for example, may be improved by doping with impurities (4). Contamination by undesirable species must at the same time be limited. In general, depending primarily on temperature, molecular transport occurs in and between phases (5), but it is unlikely that the concentration ratios of molecular species is uniform from one phase to another or that, within one phase, all partial concentrations or their ratios are uniform. Molecular concentrations and species that are anathema in one appHcation may be tolerable or even desirable in another. Toxic and other types of dangerous gases are handled or generated in vacuum systems. Safety procedures have been discussed (6,7). 

Analysts should discuss sample-collection methods with those responsible. Frequently, the methods result in biased data due to venting, failure to blow down the sample lines, and contamination. These are limitations that must either be corrected or accepted and understood. Sampling must be conducted within the safety procedures established for the unit. Since samples may be hot, toxic, or reactive in the presence of oxygen, the sample gatherers must be aware of and implement the safety procedures of the unit.

Ascertain that each accident or illness was investigated promptly to determine the cause and make necessary changes in health and safety procedures. 

The audit includes a review of the process safety information, inspection of the physical facilities, and interviews with all levels of plant personnel. Using the procedures and checklist, the team systematically analyzes compliance with the PSM Rule and any other relevant corporate policies. The training program is reviewed for adequacy of content, frequency and effectiveness of training. Interviews determine employee knowledge and awareness ofthe safety procedures, duties, rules, and emergency response assignments. The team identifies deficiencies in the application of safety and health policies, procedures, and work authorization practices to determine live actions. 

Accident defenses may be regarded as a series of barriers (engineered safety systems, safety procedures, emergency training, etc.). As barriers fail, incipient failures become real. Inappropriate management policies create inadequate PIFs, which give rise to opportunities foi ermr when initiated by local triggers or unusual conditions. 

The fact that the model connecting error types with their causes may change as a result of gaining further experience with the data collection system means that the informahon gathered on the PIFs in a situation may also change. For example, if incident data indicates the neglect of safety procedures because of production pressures, then the questions relating to this area wUl need to be extended. 

The DS team spent one session compiling a list of the documentation requirements that they were aware of from their individual experiences. This documentation ranged from vessel details and drawings to accident/incident reporting to MSDSs to safety procedures. Many different departments and functions were involved. Some documentation was kept in hard copy form, while the rest was in electronic form but on several different systems. The... 

The event or series of events diat will inidate an accident has to be identified. An event could be a failure to follow correct safety procedures, improperly repaired equipment, or failure of a safety mechanism. 

A process checklist evaluates equipment, materials and safety procedures. A checklist is composed of a series of questions prepared by an engineer who knows the procedure being evaluated. It compares what is in tlie actual plant to a set of safety and company standards. Some questions tliat may be on a t>pical checklist are ... 

This rather complicated procedure has been necessary because the drilling rig can only accommodate the BOP stack that has only one set of pipe rams and a blind ram (i.e.. Figure 4-188). It is obvious if the rig could accommodate the taller BOP stack with two pipe rams (namely Figure 4-187), one pipe ram could be for 3 in. drill pipe and the other for the 4 in. liner. Such an arrangement would greatly simplify the safety procedures necessary for placing the 4 in. liner into the borehole. 

When a well is making (formation) gas, the rig crews must be constantly alert to safety and proper safety procedures, and rules must be followed. Nearly all drilling companies strictly forbid any smoking material, lighters or matches to be taken into the areas where air (or gas) is being used to drill a well for hydrocarbons [75]. 

Note that the following procedures only provide a framework in which specific health and safety procedures for the individual works or premises may be prepared. A senior member of the company or the person nominated as responsible for health and safety in the organization should write the foreword to a company s procedure. To emphasize its importance it should also include a part of the company s health and safety statement. It should be followed by an instruction such as You are required to read the following procedures carefully and comply with the sections relevant to your workplace . 

Safety procedures must be observed in the laboratory at all times. Many chemicals encountered in analysis are poisonous and must be carefully handled. Whereas the dangerous properties of concentrated acids and of widely recognised poisons such as potassium cyanide are well known, the dangers associated with organo-chlorine solvents, benzene and many other chemicals are less apparent.
