Steering System Safety

Trailer separation can occur due to improper hitching, or inadequate or damaged equipment. Pintle hooks and ball hitches may uncouple if impropeily latched. Hitch

Walkie trucks can be considered the battery-powered version of the hand-operated forklift trucks. They are equipped with wheeled forks used to lift loads. The worker usually does not ride on the vehicle, but he controls the speed and the steering systems by using a control handle in front of the vehicle. For safety reasons, the maximum speed is limited to about 5 km/h, therefore no more than the normal speed of a human worker. 

Does your preventive maintenance and inspection program recognize the following safety-related vehicle components whose deterioration directly affects vehicle control - braking system - steering system - couplers - tires and wheels - suspension... 

The Consumer Product Safety Commission (CPSC) estimates that there has been about 500,000 nonfatal bicycle-related injuries treated in emergency rooms every year since the early 1970s. About 30 percent of these incidents involved head or face injuries. Additionally, it is estimated that there may be as many as 1000 bicycle-related fatalities annually, and about 90 percent of these incidents involve motor vehicles. The CPSC bicycle standard (16 CFR Part 1512), effective in 1976, set safety requirements for reflectors, wheels, tires, chains, pedals, braking and steering systems, and for the frame and fork structural components. The CPSC Bicycle Helmet Standard (16 CFR 1203) sets forth the requirements for bicycle helmets (Figure B.l). Biohazard... 

The control rod steering computers already mentioned were subjected to a qualification procedure that was not as rigorous as it would have been for a reactor protection system. This was due to the lower safety relevance of the control rod steering system. However, due to its operational success, it was chosen as the object for a rigorous post-qualification procedure in order to determine the effectiveness of the qualification methods. 

Functional safeguarding with hydraulic systems has always been used for automobiles. A typical example would be the dual-circuit braking system or the hydraulic steering system. Electronic and software based functional safety mechanisms were introduced as for example the ABS (Anti-Wheel-Blocking-System) for brake systems 30 years ago. Prior to that the necessary safety was only established by sufficient robust system and safe component characteristics (meaning through design). 

The Scania plant at Falun in Sweden manufaetures bus and truck steering knuckles. These are safety-critical components that are specified as having to be crack-free. For this reason, every component is now inspected using an automatic process that ensures the appropiate inspection is consistently canied out to the required standards of quality. Photos of the system are shown in Fig 1. The principle of operation is as follows. 

In the United States, regulation of emissions from new automotive vehicles has followed the prototype-replicate route. The argument for routine annual automobile inspection is that cars should be regularly inspected for safety (brakes, lights, steering, and tires) and that the additional time and cost required to check the car s emission control system during the same inspection will be minimal. Such an inspection certainly pinpoints cars whose emission control system has been removed, altered, damaged, or deteriorated and force such defects to be remedied. The question is whether... 

Applications for physical sensors are dominated by the automotive industry. Engines are monitored and controlled by various sensors, and most cars are equipped with systems to enhance safety for brakes, steering, chassis, and even crashes. Controlling airflow and temperature in the cabin enhances the comfort of drivers. 

Since late 2005, the ICH has added three more quality guidelines Q8— Pharmaceutical Development, Q9—Quality Risk Management, and QIO— Pharmaceutical Quality System. All these guidelines are intended to bolster the quality of drugs to be manufactured, steering manufacturers in the direction to improve compliance, safety, and consistency of the drugs. 

This system improves driving safety by preventing lateral instability of the vehicle. Besides sensors for wheel speed, steering-wheel movement, and yaw rate, a high-pressure sensor is needed to detect the brake pressure. 

Electronic control systems such as ESP, EPS, ABC, ECD, ACC, and navigation systems need steering-angle data as part of the information available on the vehicle network (CAN = control area network). Some ESP system suppliers and car manufacturers require an SAS to fulfill safety requirements. Fig. 7.11.2 shows a modular approach around an SAS core technology.

The first step towards safety for the individual healthcare professional is to appreciate the ubiquity and multiple sources of error and hazard and then consider how it applies in one s own environment. Which are the most dangerous processes on the ward Which are most prone to error and failure When is the system at its most vulnerable When are errors most likely to occur What are the principal forms of harm that may afflict patients in this environment Really grappling with this requires openness about error and a willingness to discuss the hazards and dangers of the environment, as a team is much more likely to be able to monitor and prevent error than an individual. Anyone at any level can foster openness about error and hazard. A nurse running a ward can make it clear that it is acceptable to discuss the possibility of error can constantly reinforce the possibilities for error, the need for anticipation and cross-checking. The most junior nurse can steer a new doctor away from a hazardous situation. All of this is critical safety conscious behaviour.
