Work at working safely

Cut-oul wind speed is the maximum w ind speed beyond which the prime mover may overspeed above its permissible limits. As the structure and the blades are designed for a particular maximum speed, a wind speed higher than this may exceed their mechanical endurance and become unsafe. At this speed the brakes apply and the machine is disconnected from the grid. The cut-in and cut-out speeds define the wind speed limits within which the turbine will work safely through the generator. Rated wind speed is the speed at which the prime mover rotates at the rated negative slip and generates the rated power. 

Both Cr111 and Cr concentrations in natural water samples were measured by flame AAS after pre-concentrations of the chromium species on microcolumns packed with activated alumina (acidic form) (Sperling et al., 1992). An FI manifold was used in this work to obtain conditions for species-selective sorption and subsequent elution of the chromium species directly to the nebuliser of the spectrometer. In this procedure, water samples were maintained at a safe pH of 4 prior to analysis. Analytical conditions of pH 2 and 7 were attained by adding buffers on-line only fractions of a second before the corresponding chromium species was sorbed into the column. In this manner, any risk of losses of analytes and/or shifts in equilibria between the species at pH 2 and 7 were minimised. The detection limits were 1.0 and O.Smgdm 3 for Cr111 and Cr, respectively. 

It has been emphasized already that you should be familiar with the regulations and codes of practice pertaining in your laboratory. We will not discuss safety legislation here but some fundamental rules should be stressed. Never work alone in a laboratory. Always wear suitable safety spectacles and a cotton lab coat, and use other protection such as gloves, face masks, or safety shields if there is a particular hazard. Never eat, drink or smoke in a laboratory. Work at a safe, steady pace, and keep your bench and your lab clean and tidy. Familiarity breeds contempt do not allow yourself to get careless with everyday dangers such as solvent flammability. Familiarize yourself with the location and operation of the safety equipment in your laboratory. 

The professor left. The Captain was a big but not fat man, about forty years old, and he spoke in a formal manner. Mr. Johnston, he said, I am a medical officer in the Chemical Warfare Service. Questions have been raised in connection with your application for SECRET clearance and concerning your suitability to work safely on Dickinson s project. I am here to interview you concerning these and other questions. I was shocked at the idea that I might not be able to work safely in Dickinson s laboratory. 

Providing for one or more standby buddy persons, who is equally protected, at a safe distance from the work area but maintaining visual contact with the worker. 

The SWGR and MCC eqnipment are invariably housed in a building or enclosed module, or at least effectively protected against bad weather and aggressive environmental conditions. The constrnction is therefore of the metal clad type, in which all the live parts are housed in a mild-steel sheet metal enclosure. The enclosure is sub-divided so that personnel may work safely on some compartments without danger or the risk of electric shock. 

Under an annually renewed, systemwide contract with WGI, Rockwell Automation works with all of the incineration sites through surveys and visits to forecast requirements for control system spares (based on historical and forecast spares depletion rates), establish certified spares inventory levels for each site, repair or rebuild failed parts and components, and to special-build new parts and circuit cards as needed to keep maintenance inventories at a safe operational level. The Rockwell Automation support group, located in Cleveland, Ohio, also implemented a relatively simple soft-... 

In summary, selection processes can help to ensure new employee safety if they clearly define the knowledge, skills, and abilities that are required to perform a job, and obtain or develop accurate predictors of these. Put simply if an organization selects an individual for a job that does not have the knowledge, skills, and abilities which are necessary to perform the job in a safe manner, there will be an increased chance that the individual (the new employee) will be involved in an accident. Of course, working safely is also partly dependent on the new employee s attitude toward safety and on their personality (see Chap. 5). Unfortunately, attitudes and personality are not easy to measure in an error-free way. In this regard, an organization should not assume that they have very much ability at all to predict safety-related attitudes or to determine much in the way of safety behavior based on personality profiling.

Another difficulty with the use of ALARP is that the term is defined by those who will not be exposed to the risk, i.e., the managers, consultants, and engineers who work safely in offices located a long way from the facility being analyzed. Were the workers at the site be allowed to define ALARP, it is more than likely that they would come up with a much lower value. 

Narcosis of sufficient degree to increase accident proneness (narcosis affects a person s judgment and can impair their abihty to work safely). No more than four excursions per day are permitted with at least 60 minutes between excursions and provided that the 8-hour TLV-TWA is not exceeded. 

We need to understand the reasons people work safely or take risks at work and we need to create a work environment that supports people in working safely [p. 44]. 

An alternative approach to the intrinsic DNA electrochemical activity utilizes electroactive species as redox indicators of the presence of immobilized DNA as well as its interaction events such as hybridization, damage, and association with another substance [14]. This mode was also used in a pioneering work on the DNA biosensor used for sequence detection [7]. In this case, it is still a label-free method in the sense that DNA probes or targets are not chemically modified by a special label however, as the indicator has to be added to a test S5 em as an additional reagent, we cannot speak more about the reagent-less technique. Redox indicators typically possess electrochemical responses at a "safe" electrode potential and often reversibly. The terms redox probe and redox marker are sometimes used in the literature to mean the redox indicator, which is confusable with the DNA capture probe used as a recognition element at hybridization and with markers used in medical diagnostics [8]. 

The second billboard clearly states that if you do not work safely, then you are not welcome at this company. (It s OK not to wear your vehicle safety belt, but woe betide being injured, that means you were unsafe.)... 

Old safety philosophy assumes that at any given time workers make a choice to work safe or not, whereas modem safety thinking assumes that accidents are defects in the total system and that people are only a part of the system. 

Taking medicines can affect peoples ability to work safely, as can the effects of alcohol. Abuse of drugs or substances such as solvents can also cause accidents at work. 

Preventative maintenance is needed to identify potential failures before employees are put at risk of injury. Worn or defective parts need to be repaired or replaced and adjustments need to be made at set intervals to ensure the press will continue to work safely, in particular those parts that could cause danger if they failed or deteriorated such as brakes, clutches, guards and safety-related parts of the control system. 

While testing acid pumps (after completing some maintenance work) always stand at a safe distance, and be ready to switch the pump off immediately if a leak is noticed.
