Robot Hazards
Introduction: the aim of this assignment is to gain general awareness and an understanding of the legal requirements and responsibilities that are involved in the safe working practices associated with robotic assisted manufacture. This is to be achieved by the identification of associated hazards with robotic applications and provide an understanding of how these hazards are overcome.
Typical sources of hazards associated with robotic operations within the working environment include.
· Crushing
· Shearing
· Striking
· Entrapment / entanglement
· Process hazards such as toxic fumes, welding flash, lasers, dust, coolant, high-pressure water jet, unguarded abrasive wheel etc.
· Fire if the robot is function's by use of hydraulics
As a matter of good system design all moving parts of the robot system should by design or enclosure eliminate / minimise all possibilities of the above from happening
The source for theses types of hazards can be caused by
Unknown / unintentional or un-covenanted movements this could be in the form of unpredictable movements whilst the equipment is being maintained or at the reinstatement of power. Other causes may be due to the corruption of software, or damage to the any of the peripherals or programmable electronics.
End effecter malfunction, which may result in a component ejection hazard, which can be due to a malfunction of the control system, or programming error.
Both of the above may occur as a result of a pneumatic or hydraulic equipment dump fault, as either may have a reservoir and could be subjected to sudden movements of one or more actuators when a jam-up is freed.
Hazards may arise from problems when interfacing with other machinery and equipmen...

...subject, I have found it to be difficult in obtaining some of the information required to complete this assignment.
In particular I have been unable to obtain referencing material to the EN 775 standard which is needed to cover section 4 of the brief, even after going to the BSI website.
The other areas of the assignment were made easier as I found that a lot of the information to be on the HSE website.
Overall I believe that I have covered all of the assignment that is possible in light of not being able to cover section 4 hence the reason that I have expanded the safety devices section somewhat.

In order to complete this assignments I need to gather as much information as I can from different sources, such as course notes, internet and a Newspaper.
Because of this assignment, I have expanded my knowledge on this subject and I believe this will greatly help me in the future.
The above excerpt was provided so that the student would know the focus of the essay. The complete essay begins below.
Section 8 of the Safety, Health and Welfare at Work Act (2005) puts the onus on the employer to ensure systems of work that are planned, organised, performed, maintained and revised as appropriate so as to be, so far as is reasonably practicable, safe and without risk to health. Section 19 of the Act requires the employer to conduct a risk assessment of work activities and Schedule 3 of the Act provides the general principles of prevention to ensure the safety of employees in the workplace.

Within the Care Industry the Occupational Safety and Health Administration (2010) stated that “nursing aides, orderlies and attendants had the highest rate of musculoskeletal disorders of all occupations in 2010”.
a) Failure of winding due to short circuits (turn-turn faults and open winding) [63] [64].
Robots are used in factories and even in people’s homes. So what if the Terminator film series got it right? Human workers, who work in factories, machineries, mills, everyday human controlled jobs like cash registers operators, are being replaced by robotic automation. This is a major problem for the everyday employee. Jobs that were once held by human workers, are now being replaced every day by robot “workers”.
Technological and accidental hazards can be occur without warning and can be both hazardous material incidents and failures at nuclear power plant. In some cases, victims that have been exposed to harmful chemicals or radiation show little to no symptoms until several years later. There are an increasing number of new substances and chemicals being manufactured which has increased the likelihood of a hazardous material spill or release. This also increases the risk to the environment and to the health and safety of a community.
circumstances and failures that can occur in any element of power system. Moreover, the rapid
The primary cause is of airplane accidents does at some stage contain an element of a person being unable to discharge his duties correctly and in an accurate manner. More than 53% accidents are the result of ignorance or faults by the pilot during flight. Other staff is responsible for about 8% accidents. The most obvious errors by pilot are made during the take off or landing on the runway. Additionally errors can occur during the maintenance of the airplane outside the plane, whereby a lack of thorough inspection and oversight can lead to complication during mid-flight. Fueling and loading of the plane also sometimes create problems (Shapiro, 2001).
To begin with, the first type of hazard/exposure is fire and explosion. Fire is highly flammable and the vapor is heavier than normal air. It can travel for a considerable distance to source of ignition and flash back. Fire can be of 3 types: small, large and fire involving tanks or cars or trailer loads. An acute hazard can be the vapor/air mixtures that cause explosions. One way of preventing is to not open flames and sparks as well as no smoking. It is also preferable to take off reactions in clo...
The report I am going to write about is to do with electrical safety devices and safety practices which contribute in reducing and eliminate specific risks. The workplace I have chosen to write about is electricians in power stations. The report I am going to write is going to show a clear understanding of electrical safety devices and the improvements of electrical safety devices.
Each of the six basic styles of robot used in industry today were designed with different applications in mind. Some of the robots were designed for assembly, others are more suited for simple pick and place applications, while a select few are capable of carrying heavy loads over a large area.
