Activity hazard analysis

The regulation requires preparation of an activity hazard analysis (AHA) before beginning each phase of work. This analysis addresses the hazards for each activity performed in the upcoming phase. It presents procedures and safeguards necessary to eliminate the hazards or reduce the risks to acceptable levels. [Pg.566]

The Corps of Engineers use a form oftheJHA process called Activity Hazard Analysis (AHA) on construction sites. The AHA is developed prior to performing any new task. [Pg.244]

The Corps ofEngineers uses a form of the JHA process called Activity hazard analysis (AHA) on all construction sites. Before beginning each work activity involving a type of work presenting hazards not experienced in previous project operations or where a new work crew or sub-contractor is to perform the work, the Contractor(s) performing that work activity shall prepare an AHA (Army System Safety Management Guide, 2008). [Pg.10]

Various analytical tools can be used in conjunction with the JHA process. These are used for specific purposes or conditions depending on the industry and range widely complexity. Examples would include — Process Hazard Analysis," What-If Analysis and Checklists for scenario development. Hazard and Operability Studies (HAZOP), Failure Mode and Efiect Analysis (FMEA), Fault-tree Analysis, Activity Hazard Analysis (Appendix H). [Pg.167]

The employer establishes a system to promptly address the team s results, timely resolve recommendations, schedule completion, and communicate the activities to affected personnel, livery five years after the completion of the initial process hazard analysis, it is equivalently updated and revalidated. Employers retain the required process hazards analyses for the life of the nmei-v -.. [Pg.31]

You can quickly identify these plant sections by reviewing process flow diagrams and valving arrangements. Isolation points are defined by control valves or powered block valves that can be remotely activated. Process hazard analysis techniques help you identify the maximum credible accident scenarios. (Note that manual valves should not be considered reliable isolation points unless they are located to be accessible following a major accident. However, remotely-activated valves can only be considered reliable isolation points if there are adequate reliability engineering and maintenance programs in place.)... [Pg.102]

One approach is to compare the risks, calculated from a hazard analysis, with risks that are generally considered acceptable such as, the average risks in the particular industry, and the kind of risks that people accept voluntarily. One measure of the risk to life is the Fatal Accident Frequency Rate (FAFR), defined as the number of deaths per 108 working hours. This is equivalent to the number of deaths in a group of 1000 men over their working lives. The FAFR can be calculated from statistical data for various industries and activities some of the published values are shown in Tables 9.8 and 9.9. Table 9.8 shows the relative position of the chemical industry compared with other industries Table 9.9 gives values for some of the risks that people accept voluntarily. [Pg.391]

Assessment. An analysis of the hazards present in this laboratory show the most significant hazard to be the release of vapor CSM from engineering controls and into the workplace. The significance of this hazard mandates further efforts in system safety in the form of a Preliminary Hazard List (PHL) and a Preliminary Hazard Analysis (PHA). The user must in this instance take an active role in the design review process. [Pg.213]

The void created by raised panel floors should be provided with smoke detectors and considered as a separate detection zone. The actual design and detection method used depends on several variables including ventilation and routing of electrical/data cables. Passive or active protection may be considered based on the results of a fire hazard analysis. [Pg.304]

PHA—Process hazard analysis. A hazard evaluation of broad scope that identifies and qualitatively analyzes the significance of hazardous situations associated with a process or activity. [Pg.438]

Schmidt-Lucke et al. [46] followed 120 patients (43 control subjects, 44 patients with stable CAD, and 33 patients with acute coronary syndromes) for 10 months and recorded MACE events (Fig. 7.2). Patients with reduced EPCs had significantly higher rates of MACE. When the results were analyzed by multivariate analysis, reduced EPC levels were found to be an independent predictor of worse prognosis, even after adjustment for traditional cardiovascular risk factors and disease activity (hazard ratio, 3.9 P< 0.05). [Pg.97]

The reader is urged to read Initiation of Explosives by Impact in Vol 7,135-R ff of this Encycl, Whereas that article dealt principally with the testing of expls, we shall want to include propints in the discussion. There is probably no subject in hazards analysis which is so actively studied as the role of impact, shock and thermal effects on the safety of expls and proplnts and which is as poorly understood. We have alluded to this incomplete state of theoretical development in the section of this article on Application of Computer Programming... [Pg.253]

Hazard analysis in process development is more a philosophy than a precise program. The complex and changing nature of process development requires the scientist to be constantly on guard for the unexpected and the unknown. Such programs must be flexible as well as structured most of all, they must become an established, well-integrated part of all development activities. [Pg.27]

The demonstration plot of the experimental site should be constructed to evaluate the effectiveness of phytoremediation. The field activities consist of site mobilization, plot layout an construction, and soil sampling combined with other agricultural practices designed secifically for phytoremediation and adapted for the conditions present at the site. The activities has to be conducted in accodance with the personal protective equipment, level of protection, action levels and other health and safety practices, i.e. hazard analysis general safety reccomendations evaluation of the mechanical, electrical, fire hazards, gas and power lines, heat stress, noise, chemical hazards. [Pg.300]

Hazard identification and control are important aspects of safety in a laboratory. Most hazards in a laboratory environment involve either unsafe conditions or behavior. Conditions can be controlled through proper analysis and inspection of the work environment, and implementation of controls to reduce or eliminate the exposure to these hazards. A formal job hazard analysis, where individual tasks are observed, broken down into their individual components, and analyzed for existing and potential hazards is necessary for hazard identification and corrective action. This activity must be followed by periodic formal inspections and hazard assessments. [Pg.294]

Hazard Analysis—The determination of material, system, process, and plant characteristics that can produce undesirable consequences, followed by the assessment of hazardous situations associated with a process or activity. Largely qualitative techniques are used to pinpoint weaknesses in design or operation of the facility that could lead to accidents. The Safety Analysis Report (SAR) hazard analysis examines the complete spectrum of potential accidents that could expose members of the public, on-site woikers, facility workers, and the environment to hazardous materials. [Pg.7]

For hazards that have been included in the site-wide analyses. Lists A and B at DEAR 48 CFR 970.5204-78(a) and (b) identify the applicable standards and requirements. List A consists of the required applicable Federal, State, and local laws and regulations (including DOE regulations), while List B contains the identified DOE directives appended to the contract. However, as a result of facility and activity level hazard analysis, new chemical hazards may be identified. These newly identified hazards may evoke standards not identified earlier in this process. [Pg.17]
