SAFed guidance

The complexity of choosing a disposal method or providing safe guidance for the disposal of a particular product becomes apparent vhen some of the factors that must be considered in evaluating a disposal action are listed ... 

Although this relay model is rather simple, it provides a safe guidance for retrosyn-thetic planning and its predictive capacity has been successfully tested in numerous applications. Scheme 9-18 compiles some of the targets which have been obtained in our laboratory so far [34], which are supplemented by many additional examples from other... 

At about the same time a thorough study was undertaken by the Department of Agriculture to determine which dyes, if any, were safe for use in foods and what restrictions should be placed on thek use. This monumental task eventually included a study of the chemistry and physiology of the then nearly 700 extant coal-tar dyes as well as the laws of various countries and states regarding thek use in food products. Most of this investigation was done under the guidance of Dr. Bernard C. Hesse, a German dye expert (17). 

Laboratoiy procedures may need to be evaluated against the sampling techniques and materials involved in the toll. There may be new laboratoiy chemicals and hazards to be considered. This work may have been identified in the evaluation of special analytical techniques required for the process. A good practice is to ensure that the lab technicians have the necessaiy guidance and types of equipment on hand to monitor the process and waste streams accurately and safely.

A properly written HASP should contain worker health and safety program information, guidance, and alternatives. The HASP should quickly answer the following questions What hazards are present and How can we make sure that the tasks will be performed safely The following general guidelines will help to answer these questions ... 

Safe venting of the gas relieved is of great importance. The British Gas publication Guidance Notes on the Installation of Gas Pipework, Boosters and Compressors in Customers Premises (lM/16) gives guidance on this. The main requirements are ... 

After testing for soundness it will be necessary to safely introduce gas into the pipework displacing the air or inert gas that is in it. Similarly, if pipework is decommissioned for any reason fuel gas must be displaced by air or inert gas. This is a requirement of the Gas Safety (Installation and Use) Regulations, Regulation 21. Guidance on recommended procedures is given in the British Gas publication Purging Procedures for Non-Domestic Gas Installations (IM/2). 

For further guidance it is recommended that some study should be made of books devoted to hazards and safe practices in chemical laboratories. Some institutions and organisations issue booklets dealing with these matters and further information will be found in citations 12-17 of the Bibliography, Section 3.39. 

The 5,330 hectare (13,170 acre) Savanna Army Depot Activity, north of Savanna, IL, consists of high ground and Mississippi River flood plain. In the flood plain are 223 hectares of waterways connected to the river about 10 hectares of sediment plain in these waterways are considered potentially contaminated by munitions-related compounds (see Table I). Of these compounds, only TNT has been isolated (0.3 rag/kg in one sediment sample) DNT, TNB, and RDX are associated with TNT in other munitions contexts, hence they were also included. The waterways are fished by a number of activity personnel and retirees. These persons and their families may eat some of their catch, and thereby ingest those compounds that might be present in the fish (predominantly carp and catfish, both bottom-feeders). Acceptable safe sediment level guidance for these compounds was therefore desired. 

The Army terminology for destruction of obsolete weapons Is "demilitarization". This term encompasses all the steps required to disassemble and safely destroy or decontaminate the component materials of which the munition was constructed. National Academy of Sciences and Department of the Army Guidance for demilitarization of obsolete chemical weapons (t) requires absolute safety and security, assurance of total containment of agent during processing, maximum protection of operating personnel and Incontrovertible evidence verifying the destruction of the toxic wastes. 

Conclusion Toxicity data are available for many thousands of solid, liquid, and gaseous chemicals and other materials. The data for inhalation toxicity provide guidance for concentration and duration limits, for protection of the public, chemical plant employees, and emergency response personnel. Similar data for ingestion and skin contact with toxic materials are not as readily available. Investigation into toxic effects is continuing, so that toxic materials can be handled safely. 

Injuries and fatalities from asphyxiation are often associated with personnel entry into inerted equipment or enclosures. Guidance on safe procedures for confined space access are provided by OSHA (OSHA, 29 CFR 1910.146, Confined Space Entry Standard, 2000), the American National Standards Institute (ANSI, Z117.1, Safety Requirements for Confined Spaces, 2003), Hodson (Hodson, Safe Entry into Confined Spaces, Handbook of Chemical Health and Safety, American Chemical Society, 2001), and BP (BP, Hazards of Nitrogen and Catalyst Handling, 2003). OSHA has established 19.5 vol % as the minimum safe oxygen concentration for confined space entry without supplemental oxygen supply (see Table 23-18). Note that OSHA imposes a safe upper limit on 02 concentration of 23.5 vol % to protect against the enhanced flammability hazards associated with 02-enriched atmospheres. 

Guidance can be found in the CCPS book (2007) Guidelines for Safe and Reliable Instrumented Protective Systems related to the development of the process requirements specification.
