Tool Safely

Train employees on the proper use of hand tools. The handout provided here is an overview of general rules for using hand tools. Train employees on specific information regarding the tools they work with to ensure they know how to operate their hand tools safely and effectively. 

An independent actor in a shared workplace must be aware of the possible harm and risks he causes, must have the necessary permits and licenses in effect, must use appropriate equipment and tools safely and perform the necessary periodical and implementation inspections. An independent actor must use appropriate personal protection equipment if necessary or required and follow regulations on handling hazardous substances. In addition, he must follow any safety instmctions issued by the main authority. The shared workplace model is analogous to an umbrella, where the main operator is the umbrella offering safety to the companies in its shade, making sure that every company fits and does not harm others by its actions (Fig. 2). 

Proper Use of Hand Tools. How to use a tool and how to safely use a tool are one in the same. Employees may be required to use nail guns, hammers, and other hand-held tools. Safe use of hand tools must be included in the orientation process. Following the manufacturers guidelines is highly recommended. 

Classification Societies exist to promote the safe construction of ships and to protect that condition throughout the life of the vessel. One of the tools available to shipbuilders, shipowners and surveyors that can be used to achieve these aims is Non-Destructive Examination (NDE). The intent of this presentation is to describe the application of NDE to hull structure during construction and also during periodic surveys as seen from the viewpoint of the Classification Surveyor. 

Other than the obvious advantages of reduced fluorescence and high resolution, FT Raman is fast, safe and requires mmimal skill, making it a popular analytic tool for the characterization of organic compounds, polymers, inorganic materials and surfaces and has been employed in many biological applications [41]. 

Reactive System Screening Tool (RSST) The RSST is a calorimeter that quickly and safely determines reactive chemical hazards. It approaches the ease of use of the DSC with the accuracy of the VSP. The apparatus measures sample temperature and pressure within a sample containment vessel. Tne RSST determines the potential for runaway reactions and measures the rate of temperature and pressure rise (for gassy reactions) to allow determinations of the energy and gas release rates. This information can be combined with simplified methods to assess reac tor safety system relief vent reqiiire-ments. It is especially useful when there is a need to screen a large number of different chemicals and processes. 

We must not forget the client. The client review is an excellent tool that can be used to get the client s first impression of safety performance. This has been shown to be especially effective when conducted on a formal basis after a phase of the project, or the entire project, has been completed. The PM and the SM should arrange to meet the client represen-tative(s) in a face-to-face meeting to discuss safety performance and possibly other parameters of the recently completed job, or phase of job. The information obtained from the review is immediately analyzed. Once analyzed, it can be used to prevent recurrences of identified problems, to publicize good practices and innovative approaches to problem solving, and to perform work more safely and efficiently. 

It is important to assign both authority and specific responsibility to implement each protective measure. A safety engineer may need to provide the training the manager should provide safe tools and equipment and the employees should inspect their tools to ensure that they are in safe condition. 

Hazard controls include engineering and administrative controls and PPE. Hazard characterization is a tool that is used to develop hazard controls and safe work practices and procedures and to make sure that the appropriate PPE is selected for each job. 

Antifriction bearings play an important part in the safe performance of the tool. The most likely requirements for bearing placement are very loose or bent cages (retainers), corrosion, abrasion, inadequate (or improper) lubrication, and spalling from fatigue. Excessive clearance may indicate improper adjustment or assembly and should be corrected. Repair of antifriction bearings should not be attempted by field or shop personnel. Consultation with the equipment manufacturer is recommended in case of unexplained or repeated bearing failure. 

Code of Practice No. 4, Safe and Satisfactory Operation of Propane-Fired Bitumen Boilers, Mastic Asphalt Cauldrons/Mixers, and Hand Tools Code of Practice No. 7, Storage of Full and Empty LPG Cylinders and Cartridges Code of Practice No. 9, LPG-Air Plants Code of Practice No. 10, Recommendations for Safe Handling of LPG in Small Trailer Mounted Vessels, Skid Tanks and Small Bulk Storage Vessels Permanently Attached to Mobile Gas-fired Equipment... 

Good housekeeping can play a major part in maintaining a safe and environmentally sound place of work. Tripping over material not tidied away causes many accidents. Another source of potential injury is in the lack of secure storage of cleaning equipment, tools, etc. 

All process equipment has procedures to operate and meet safety requirements. They include a checklist that includes preparation (moving material, etc.), startup and shutdown procedures, tooling changes, and to cleanup of all equipment. Most equipment generates high heats and pressures. They are built to run safely, but they must be treated with respect . 

New process technologies (Ref 53) such as jet mills (Fig 2) and co-precipitation (Ref 97) may allow safe compounding of sensitive or toxic formulations. New analytical tools such as neutron radiography (Ref 92) afford improved non-destructive testing of devices. X-ray fluorescence (Ref 93) and neutron activation (Ref 94) provide quantitative analysis of pyrotechnic compns and their trace contaminants... 

Developing new chemical engineering design tools to deal with the multiple objectives of minimum cost process resilience to changes in inputs minimization of toxic intermediates and products and safe response to upset conditions, start-up, and shutdown.
