Accidents reviewing history

Hazard Reviews. Formal and informal hazard reviews are essential to establishing an operational history that is free of accidents. Reviews should be made at key points during the selection, design, construction, start-up and operation of a system. Such reviews are cost-effective because they identify hazards and permit problems to be solved before incorrect and... 

Review the case histories described in the booklet by Marsh McLennan,31 and document the number of accidents that occurred in refineries and in petrochemical plants. 

Program Level 1 Conduct a worst-case release scenario analysis, review accident history, ensure emergency response procedures are in place and coordinated with community officials. 

The chemistry involved in this explosively unstable system is reviewed [1], The mechanism of the trigger reactions that initiate the exothermic decomposition of chlorate—sulfur mixtures has been studied. Mixtures containing 1—30% of sulfur can decompose well below the m.p. of sulfur, and addition of sulfur dioxide, the suspected chemical trigger, causes immediate onset of the reaction [2], Autoignition of stoichiometric mixtures can be as low as 115°C, with frictional sensitivity at 5N, the lowest load the test apparatus permitted. Both were dependent upon the history of the sulphur used [3]. An account of historical explosions includes contemporary accounts of the fatal 18th century accidents resulting from the attempt to replace the nitrate in black powder by chlorate [4],... 

Improper or insufficient maintenance can lead to serious personnel or process accidents. Occasionally, well-intended maintenance activities inadvertendy introduce an unwanted situation into a carefully engineered plant. A lack of a maintenance program with proper inspections and tests can also result in accidents. This chapter will review both of these maintenance causes of accidents while emphasizing piping-related case histories. 

This chapter examines die history of accidents from early incidents to recent catastrophes. In conjunction widi diis review, die material will study the evolution of safety precautions, particularly as diey apply to chemical plants. A crucial part of any design project is the inclusion of safety controls. Wliedier die plans involve a chemical plant, a nuclear reactor, or a dmiway, steps must be taken to minimize the likelihood, or eonsequences, of accidents. It is also important to realize how accident plaiming lias improved in order to monitor today s adi anced teclmologies. This cliapter reviews a variety of actual accidents in order to provide an understanding of diese phenomena, which will supplement the subsequent chapters tliat deal widi diese subjects in significant detail. 

Numerous other case histories of interest may be found in the MCA compilation, in the review of liquid hydrogen hazards by Wein-traub, and in the article on oxygen plant safety by McKinley and Himmelberger, and that on hazards in cryogenic systems by Van Dyke. " An analysis of a number of accidents indicates the following... 

One of your drivers is involved in his third accident in the last 12 months. This time a big one, involving two other vehicles and several injuries. A review of his DQ file reveals a history of unsafe driving behavior includ-... 

In addition to the five regulatoiy factors, a sixth factor addresses the accident history of the motor carrier. This factor is the recordable accident rate the carrier has experienced during the past 12 months. This factor will he used only when a motor carrier incurs two or more recordable accidents within the 12 months prior to the compliance review. 

Review your company s accident/ipjury/illness/near-miss history to determine which jobs pose the highest risk. 

As one reviews the early history of criticality safety there is good evidence that standard industrial accident prevention techniques served well. Where there were failures, the evidence was not obscure that Simple, straUd>tforward multiple techniques of procedural control would produce the level of accident control required even by a changing social climate. 

Past accident and maintenance history. When records have been reviewed or copied, check. ... 

Plant event history and/or similar plant event, major accident/incident event information or near miss issues should be reviewed. Here one point must be... 

Her past medical history was without significance. She had had no falls or accidents. She used only birth control medication and a vitamin. She had no allergies. The review of systems was non-contributory. 

Safety Performance History is a background investigation that motor carriers are required to obtain and review for each job applicant seeking emplo5mient as a commercial motor vehicle driver. The inquiry includes three years worth of information about where the driver worked, the motor vehicle accidents he/she was involved in, and the driver s DOT drug/alcohol testing history. 

Scaling up exothermic chemical reactions can be very tricky. Tables 12-5 and 12-6 give reactions that have resulted in accidents and their causes, respectively. The reader should review the case histories of these reactions to learn how to avoid similar accidents. 

SAFETY SCREENING - A 3-year accident history review indicates the following (This can be quickly accomplished using readily available products from the Department s Safety Information Management System (SIMS) and the computerized TE-164 methodology).
